Since Dr. Frank Jobe performed the initial surgery on Tommy John in 1974, the ulnar collateral ligament (UCL) reconstruction (UCLR), colloquially "Tommy John Surgery," described in 1986 has evolved as the gold standard treatment for UCL tears. The crux of technique modifications involve flexor pronator mass (FPM) management, ulnar nerve transposition (UNT), graft selection, or graft-fixation options. Jobe used a figure-of-8 graft fixation through the cubital tunnel, necessitating FPM elevation and UNT. Although 68% of patients returned to play (RTP), 25% of patients experienced ulnar neuritis, prompting change. Described by Thompson et al. in 2001, the modified Jobe technique implemented a muscle-splitting approach to the FPM, eliminating the need for FPM elevation, facilitating optional UNT. This technique uses larger tunnel sizes to facilitate graft passage in a figure-of-8 fashion. Graft selection is another consideration in UCLR. Most commonly, the palmaris longus autograft is used. In addition, there are no significant outcome differences between alternative graft types such as allografts, hamstring autografts, or extensor tendons. Notably, palmaris longus autograft is perhaps a high-risk choice, given the proximity to the median nerve. One case series reported 19 incidents of iatrogenic median nerve harvest. Lastly, the docking technique, from Altchek et al. in 2002, builds upon the modified Jobe. Using the FPM split, optional UNT enhanced graft passage and fixation with one humeral tunnel and smaller exit holes. This approach demonstrates a remarkable 90% RTP at 12 to 18 months, ultimately leading to satisfactory outcomes and potentially shorter operating room times. An alternative approach to UCLR, UCL repair with suture augmentation obviates the need for a graft, shortening RTP time to approximately 6 months. Historically, UCL repair indications were inconsistent; however, the current professional consensus suggests acute injuries, minimal ligamentous degeneration, or isolated proximal or distal avulsions may be optimal injury patterns for repair., Competing Interests: Disclosures The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: B.J.E. reports board or committee member of American Academy of Orthopaedic Surgeons, American Orthopaedic Society for Sports Medicine, and American Shoulder and Elbow Surgeons; paid consultant for and research support from Arthrex; research support from Depuy (A Johnson & Johnson Company), Linvatec, Smith & Nephew, and Stryker; and editorial or governing board of PLOS One.

Purpose: The aim of this systematic review is to review the functional, clinical and radiological outcomes of patients undergoing large to massive rotator cuff repair with long head of biceps tendon (LHBT) autograft, as well as compare these to standard arthroscopic cuff repair., Methods: A review of the online Medline database was conducted on 20 October 2022 according to PRISMA guidelines and registered prospectively on the PROSPERO database. Clinical studies assessing patients with large to massive rotator cuff tears undergoing LHBT autograft repair were included. All studies reported on functional outcomes, range of movement (ROM) and radiological re-tear rates. The Methodological Index for Non-Randomised Studies (MINORS) tool was used to appraise all studies., Results: The search strategy identified ten studies for inclusion including a total of 594 patients. Five studies were comparable (346 patients), assessing LHBT autograft repair against arthroscopic rotator cuff repair without autograft. A variety of techniques of LHBT autograft were used across all studies, including bridging and augmentation styles. Radiographic comparison showed lower re-tear rates in the LHBT autograft group with two studies demonstrating statistically significant results. Pain scores, functional outcomes and ROM were significantly improved post-operatively in all studies for LHBT autograft patients, with no significant difference when compared to standard arthroscopic repair., Conclusion: LHBT autograft looks to significantly improve functional scoring and range of motion in patients with large to massive rotator cuff tears. When compared to standard arthroscopic cuff repair, LHBT autograft appears to significantly reduce the re-tear rate. Further randomised studies are needed to assess the efficacy of this technique., (© 2024. Crown.)

Anterior cruciate ligament reconstruction (ACLR) is one of the more common procedures performed worldwide and perhaps the most widely studied construct in orthopedic literature. Interference screws are reliable and frequently used for ligament reconstruction, providing rigid fixation and facilitates graft incorporation allowing for the physiologic loads of early rehabilitation. The purpose of this study was to determine the bio-integration profile and quality of soft tissue graft when using mineral fiber-reinforced screws in an ACLR interference model. Nine sheep underwent ACLR using harvested autologous tendon graft fixated with 4.75 mm screws made of continuous mineral fibers. Histopathology and imaging evaluation at 28, 52, 104, 132-weeks (W) demonstrated mesenchymal tissue ingrowth into implant wall at 28 W, which increased at 52 W and peaked at 104 W. At 132 W, implants fully replaced by newly remodeled bone. Graft cellularity was evident at 28 W and continued to increase through 132 W as the tendon ossified at sites of bone contact. Pro-healing M2-macrophages and giant cells remained infrequent, with minor increases between 52 W and 104 W, attributed to expected phagocytic response. Pro-inflammatory cells (i.e., M1-macrophages, polymorphonuclears) were absent through the entire study course. In conclusion, bio-integrative screws provide secure soft tissue fixation with replacement by bone demonstrating graft cellularization over time., (© 2024. The Author(s).)

Our hypothesis is that the peroneus longus (PL) is a great option for ligament reconstruction in the knee, and therefore the objective of the study is to determine if the use of this graft is safe and does not cause secondary damage to the harvested area. A prospective study was conducted between April 2019 and September 2022. Patients who underwent any type of knee ligament reconstruction using the PL or just the anterior half (AHPL) as grafts were followed up. These patients were evaluated according to the Tegner-Lysholm score and the International Knee Documentation Committee (IKDC) guidelines for functional evaluation of the knee and the American Orthopedic Foot and Ankle Score (AOFAS) and the Foot and Ankle Disability Index (FADI) for the functional evaluation of the ankle. Most patients had an increase in the IKDC score, Tegner-Lysholm score, AOFAS and FADI regardless of the graft used in the surgical procedure, with mean values at the 24-month follow-up of, respectively, 99.02± 0.02, 98.69± 0.08, 99.92± 0.07, and 99.92± 0.07 for those with PL grafts and 99.31± 0.54, 98.88± 0.95, 100± 0.00, and 100± 0.00 for those with AHPL grafts. The differences in the scores between the two graft groups during each of the follow-up periods were significant (P = 0.001). The use of the peroneus longus tendon as a graft in knee surgeries was shown to be adequate for achieving good knee functional results., (© 2024. The Author(s).)

Background: Rotator cuff repair augmentation using biological materials has become popular in clinical practice to reduce the high retear rates associated with traditional repair techniques. Tissue engineering approaches, such as engineered tendon-fibrocartilage-bone composite (TFBC), have shown promise in enhancing the biological healing of rotator cuff tears in animals. However, previous studies have provided limited long-term data on TFBC repair outcomes. The effect of mechanical stimulation on TFBC has not been explored extensively., Purpose: To evaluate functional outcomes after rotator cuff repair with engineered TFBC subjected to mechanical stimulation in a 6-month follow-up using a canine in vivo model., Study Design: Controlled laboratory study., Methods: A total of 40 canines with an acute infraspinatus (ISP) tendon transection model were randomly allocated to 4 groups (n =10): (1) unilateral ISP tendon undergoing suture repair only (control surgery); (2) augmentation with engineered TFBC alone (TFBC); (3) augmentation with engineered TFBC and bone marrow-derived stem cells (BMSCs) (TFBC+C); and (4) augmentation with engineered TFBC and BMSCs, as well as mechanical stimulation (TFBC+C+M). Outcome measures-including biomechanical evaluations such as failure strength, stiffness, failure mode, gross appearance, ISP tendon and muscle morphological assessment, and histological analysis-were performed 6 months after surgery., Results: As shown in the mechanical test, the TFBC+C+M group exhibited higher failure strength compared with other repair techniques. The most common failure mode was avulsion fracture in the TFBC+C+M group, but tendon-bone junction rupture was observed predominantly in different groups. Engineered TFBC with mechanical stimulation showed over 70% relative failure strength compared with normal ISP, and the other groups showed about 50% relative failure strength. Histological analysis revealed less fat infiltration and closer-to-normal muscle fiber structure in the mechanical stimulation group., Conclusion: This study provides evidence that mechanical stimulation of engineered TFBC promotes rotator cuff regeneration, thus supporting its potential for rotator cuff repair augmentation., Clinical Relevance: This study provides valuable evidence supporting the use of a novel tissue-engineered material (TFBC) in rotator cuff repair and paves the way for advancements in the field of rotator cuff regeneration., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: This work was supported by a grant from the National Institute of Health (AR73811).

Purpose: To evaluate the histologic healing process and mechanical characteristics of the interface between a fascia lata autograft and supraspinatus muscle by establishing a supraspinatus tendon reconstruction model for chronic massive irreparable rotator cuff tears (MIRCTs)., Methods: A total of 40 rats were studied. Eight rats were killed to establish an intact control group, and the other rats were first established as a chronic MIRCT model and then developed as the supraspinatus tendon reconstruction model. Histology, fatty infiltration, mechanics, and open field test for the interface between the fascia lata autograft and muscle were assessed at 2, 4, 8, and 16 weeks postoperatively., Results: Histologically, the interface between the fascia lata autograft and muscle gradually regenerated structural characteristics similar to the normal muscle-tendon interface by 16 weeks postoperatively. The amount of collagen I and III increased significantly during the healing time and stabilized at 8 weeks postoperatively. Fatty infiltration was obvious in the supraspinatus muscle 4 weeks after establishing the MIRCT model. However, the degree of fatty infiltration in the supraspinatus muscle gradually decreased after supraspinatus tendon reconstruction and stabilized at 8 weeks postoperatively. The ultimate failure force and ultimate stress gradually increased from 2 to 16 weeks and reached the level of the intact control tendon at 16 weeks postoperatively (P = .086). The movability of the forepaw returned to normal in the open field test (P = .907)., Conclusions: In this rat supraspinatus tendon reconstruction model, fascia lata autografts showed good interface healing with the supraspinatus muscle, and fatty infiltration in the supraspinatus muscle was histologically decreased. The interface between the fascia lata autograft and muscle showed mechanical strength similar to the anatomic muscle-tendon interface., Clinical Relevance: A supraspinatus tendon reconstruction technique using fascia lata autografts might be a good histologic and biomechanical option for treating MIRCTs., Competing Interests: Disclosures 'All authors (Y.L., Z.Z., J.W., H.L., B.Z.) declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.

BACKGROUND Anterior cruciate ligament (ACL) reconstruction commonly uses a hamstring tendon autograft, but the peroneus longus tendon can also be used. This study aimed to compare outcomes of anterior cruciate ligament reconstruction in 106 patients using peroneus longus tendon and hamstring tendon autografts. MATERIAL AND METHODS ACL repair was performed on 54 patients using a hamstring tendon autograft and 52 patients with a peroneus longus tendon autograft. Knee function was assessed using the International Knee Documentation Committee (IKDC) and Lysholm scores, while the ankle was evaluated using the American Orthopedic Foot and Ankle Score (AOFAS) and the Foot & Ankle Disability Index (FADI) scores. Donor-site morbidity and graft characteristics were compared. RESULTS There was no difference between the 2 groups in terms of knee IKDC and Lysholm scores (p=0.49, p=0.68, respectively). The diameter of the peroneus longus tendon graft (8.56±0.93) was significantly larger than the hamstring tendon (7.44±0.6) (p<0.001). The peroneus graft harvesting time was significantly shorter (p<0.001). Thigh hypotrophy and donor-site morbidity were significantly higher in the hamstring group (p<0.001 and p=0.006). The donor ankle AOFAS score was 93.46±3.8, and the FADI score was 93.48±4.6. No morbidity associated with the peroneus longus graft was observed. CONCLUSIONS Patients who underwent ACL reconstruction using the peroneus longus tendon experienced faster knee rehabilitation and less donor-site morbidity, such as thigh hypotrophy and knee pain. The peroneus longus tendon, with its larger diameter, fewer graft-related complications, and similar knee scores compared to the hamstring group, is considered a suitable alternative graft source.

Background: The treatment of chronic scapholunate dissociation (SLD) can be challenging due to several factors such as poor quality of ligament, malalignment of the carpus, limited surgical options, and risk of recurrent instability. Various surgical techniques have been developed, but there is ongoing debate regarding the optimal surgical technique. This study aimed to report the clinical and radiological outcomes after dorsal scapholunate (SL) ligament complex reconstruction using suture tape-augmented autologous tendon graft., Methods: The study included patients with Garcia-Elias stage 3-4 chronic SLD, SL advanced collapse (SLAC) stage 1, and a follow-up period exceeding 1 year. Pre- and postoperative SL gap, SL angle (SLA), radiolunate angle (RLA), and dorsal scaphoid translation (DST) were measured, and wrist active range of motion, Modified Mayo Wrist Score (MMWS), and visual analog scale (VAS) were evaluated., Results: Nine patients were included in this study with a mean follow-up period of 17 months (range, 15-31 months). All patients were male, with a mean age of 49 years (range, 30-62 years). Eight patients were classified as Garcia-Elias stage 4, while one was classified as SLAC 1. The median (range) of preoperative, immediate postoperative, and final follow-up measurements for SL gap, SLA, RLA, and DST were 5.4 mm (4.5-5.9), 2.1 mm (1.8-2.5), and 2.5 mm (2.0-2.8) ( p = 0.008); 76° (69°-88°), 50° (32°-56°), and 54° (50°-64°) ( p = 0.008); 22° (11.5°-33°), 2.8° (0.5°-3.8°), and 3.8° (2.2°-5.6°) ( p = 0.008); and 2.8 mm (2.0-3.4), 0.8 mm (0.1-1.2), and 1.0 mm (0.1-2.0) ( p = 0.008), respectively. Immediately after surgery, all radiological measurements showed significant improvement, which persisted up to 15 months postoperatively. The preoperative and final follow-up measurements of active flexion, extension, radial deviation, and ulnar deviation of the wrist showed significant improvement. The median preoperative and final follow-up values of MMWS were 51.1 (range, 40-60) and 88.3 (range, 85-95) ( p = 0.007), respectively, and those of VAS were 7 (range, 6-8) and 2 (range, 1-3) ( p = 0.007), respectively., Conclusions: Dorsal SL ligament complex reconstruction using suture tape-augmented autologous free tendon graft could be regarded as a feasible and straightforward technique for addressing irreparable chronic SLD., Competing Interests: CONFLICT OF INTEREST: No potential conflict of interest relevant to this article was reported., (Copyright © 2024 by The Korean Orthopaedic Association.)

Purpose: To investigate sex-based recovery differences in patients undergoing anterior cruciate ligament reconstruction (ACLR) with a hamstring (HT) or quadriceps (QT) tendon autograft., Methods: This study included 97 patients, including 50 females (HT = 25, QT = 25) and 47 males (HT = 24, QT = 23), assessed presurgery and at 12- and 24-month postoperatively via surveys, laxity, isokinetic knee extensor and flexor torque and a 6-hop performance battery. Limb symmetry indices (LSIs) were calculated. Outcomes were compared between males and females, as well as within each graft type., Results: Males reported significantly higher Tegner scores at 12 (p = 0.029) and 24 (p = 0.031) months, Anterior Cruciate Ligament Return to Sport after Injury scores at 12 (p = 0.009) and 24 (p = 0.010) months, and a significantly higher lateral hop LSI at 12 (p = 0.045) months, knee extensor torque LSI at 12 (p = 0.020) months, and knee flexor torque LSI at 12 (p = 0.001) and 24 (p = 0.039) months. Females undergoing ACLR with a QT (vs. HT) graft demonstrated a lower knee extensor torque LSI at 12 (p = 0.006) months, a lower lateral hop LSI at 12 (p = 0.038) months, and a lower medial hop LSI at 12 (p = 0.042) months., Conclusions: Females reported less activity and psychological readiness, as well as strength symmetry. Furthermore, the recovery of quadriceps strength and hop symmetry was delayed in females (vs. males) undergoing ACLR with a QT graft. A better understanding of these differences will assist in counselling on expectations, determining the most appropriate graft construct and permitting more targeted rehabilitation., Level of Evidence: Level IV., (© 2024 The Author(s).

Background: The type of the graft in anterior cruciate ligament reconstruction is still argument which one is the best regarding hamstring or bone tendon bone graft. Peroneus longus (PL) tendon is emerging good alternative choice in such type of surgery., Methods: Study done on 30 patients with anterior cruciate ligament reconstruction (ACLR) using PL graft and evaluated after 2 years with lysholm knee score and American orthopedic foot and ankle disability index., Results: Two year of surgery, the result 86-95% (good to excellent) in 22 cases (73.3%), 6 (20%) patients with 80-85% (fair to good), and 2 (6.6%) cases with 70% (poor) score without any new insult on the knee. American foot and ankle score was 100 in all 28 patients (93.3) and 96 only in 2 cases (6.6%)., Conclusion: Good size of the graft and low donor site morbidity as well as good functional outcome may make the PL graft is a favorable graft choice in ACLR.

Introduction: Cartilage is an important source in supporting the structure of the nose for dorsal augmentation rhinoplasty. However, it is known that its viability is not always on the ideal level. Various wrapping materials are used to increase the strength of cartilage. Donor site morbidity, which develops following the harvesting of both cartilage and fascia as one such cover material, has attracted interest in recent years., Objective: In this study, we aimed to investigate the potential of dermis and tendon autografts as alternatives to fascia and cartilage., Material and Method: The sample of the study included 16 New Zealand white rabbits. The right auricular cartilage of all rabbits was amputated, and it was transformed into diced cartilage autografts. The dermis autografts from the right gluteal areas of the rabbits were deepithelialized, and lumbosacral fascia autografts were harvested from the same incision. Additionally, the Achilles tendon of each rabbit was harvested and transformed into diced tendon autografts. Four different autografts were embedded under the skin of each rabbit from 4 different pouches opened in the back of the rabbit. These autografts included diced cartilage alone (Intervention 1), fascia-wrapped cartilage (Intervention 2), dermis-wrapped cartilage (Intervention 3) and fascia-wrapped tendon (Intervention 4) autografts., Results: Intervention 1 had the most irregular appearance, the outcomes in Intervention 4 were volumetrically smaller and softer. Connective tissue formed between the diced pieces in all interventions, and it was observed that the dermis and fascia had a capsule-like appearance, and their viability was preserved. The differences between the initial and final measurements of the volumes of interventions 1, 2 and 3 were statistically significant (p < 0.05). There was no significant difference between the initial and final volumetric measurements of intervention 4 (p > 0.05). More peripheral proliferation was observed in the interventions of fascia-wrapped and dermis-wrapped diced cartilage compared to the other interventions. The intervention including fascia-wrapped diced tendon grafts had displayed more fibrosis, fragmentation and collagen fibers, while it showed a lower amount of elastic fiber. There were no significant differences among the intervention in terms of other histological parameters., Conclusion: Tendon autografts may be a good option for dorsal augmentation rhinoplasty as they are easily harvested and have minimal donor site morbidity. Dermis autograft usage is more advantageous than fascia usage in terms of accessibility and convenience., No Level Assigned: This journal requires that authors assign a level of evidence to each submission to which Evidence-Based Medicine rankings are applicable.

This study aimed to compare the clinically established autologous extrasynovial tendon graft to a newly developed tissue-engineered allograft (Eng-allograft) in terms of functional outcomes following flexor tendon reconstruction in a canine model. The second and fifth flexor digitorum profundus (FDP) tendons from 16 dogs were transected and repaired in Zone II. After 6 weeks of cage activity, the repaired tendons were intentionally ruptured, creating a clinically relevant model for reconstruction. The re-ruptured FDP tendons were then reconstructed using either the clinically standard autologous extrasynovial tendon graft or the Eng-allograft, which had been revitalized with autologous bone marrow-derived mesenchymal stem cells (BMSCs) and synovialized using carbodiimide derivatized synovial fluid (cd-SYN). Following 12 weeks of postoperative rehabilitation, the functional outcomes of the surgical digits were evaluated. The Eng-allograft group exhibited improved digital function, including lower digit work of flexion and reduced adhesion status, while maintaining similar tendon gliding resistance compared to the autograft group. However, the failure load of both the distal and proximal host/graft conjunctions in the Eng-allograft group was significantly lower than that of the autograft group with higher graft rupture at the host-graft junction. In conclusion, the decellularized allogenic intrasynovial tendon, when revitalized BMSCs and synovialized with cd-SYN, demonstrates positive effects on digital function improvement and adhesion reduction. However, the healing at both proximal and distal graft/host junctions is far lower than the autograft. Further research is needed to enhance the healing capacity of allograft conjunctions, aiming to achieve a comparable level of healing seen with autografts., (© 2024 Orthopaedic Research Society.)

Objective: To compare the effectiveness of I.D.E.A.L technique and transtibial (TT) technique in anterior cruciate ligament (ACL) reconstruction., Methods: A clinical data of 60 patients with ACL injury, who were admitted and met the selection criteria between January 2020 and September 2022, was retrospectively analyzed. All patients underwent arthroscopic ACL reconstruction with autologous tendon. During operation, the femoral tunnel was prepared by using I.D.E.A.L technique in 30 cases (I.D.E.A.L group) and using TT technique in 30 cases (TT group). There was no significant difference in baseline data such as age, gender, body mass index, cause of injury, injured side, interval from injury to operation, constituent ratio of combined cartilage and meniscus injury, and preoperative Lysholm score, International Knee Documentation Committee (IKDC) score, visual analogue scale (VAS) score, anterior tibial translation difference, and Blumensaat angle between the two groups ( P >0.05). The length of hospital stay and the occurrence of early and late complications were recorded. During follow-up, the Lysholm score, IKDC score, and VAS score were used to evaluate knee joint function and pain degree, and the anterior tibial translation difference was measured. MRI reexamination was performed to observe the healing of the graft, and the signal to noise quotient (SNQ) values of the femoral end, middle section, and tibial end of the graft, as well as the Blumensaat angle of the knee joint were measured. The differences in tibial anterior translation difference and Blumensaat angle before and after operation (change values) were calculated and compared between the two groups., Results: The incisions in both groups healed by first intention after operation, and there was no significant difference in the length of hospital stay between the two groups ( P >0.05). All patients were followed up 12-18 months, with an average of 14.9 months. The Lysholm score and IKDC score of the knee joint in both groups after operation increased when compared with those before operation, and the VAS score decreased. Compared to preoperative scores, except for the VAS score of the TT group at 1 week after operation ( P >0.05), there were significant differences in all scores at different time points postoperatively in the two groups ( P <0.05). The above scores in both groups showed a further improvement trend with the prolongation of time after operation. There were significant differences in Lysholm score and VAS score among 1 week, 1 month, 3 months, 6 months, and 12 months after operation in the two groups ( P <0.05). The IKDC score of both groups at 1 month after operation was significantly different from that at 1 week after operation ( P <0.05). At 1 week after operation, the Lysholm score and IKDC score in the I.D.E.A.L group were significantly higher than those in the TT group ( P <0.05), and the VAS score was significantly lower ( P <0.05); there was no significant difference between the two groups at 1, 3, 6, and 12 months after operation ( P >0.05). At 12 months after operation, the anterior tibial translation differences in both groups were significantly lower than those before operation ( P <0.05); and the change value in the I.D.E.A.L group was significantly higher than that in the TT group ( P <0.05). The incidences of early and late complications in the I.D.E.A.L group were significantly lower than those in the TT group ( P <0.05). At 12 months after operation, MRI examination showed that the grafts of the knee joint in both groups survived well, and the Blumensaat angles of both groups were significantly smaller than those before operation ( P <0.05). The change value of the Blumensaat angle in the I.D.E.A.L group was significantly higher than that in the TT group ( P <0.05). The SNQ values of the femoral end, middle section, and tibial end of the graft in the I.D.E.A.L group were significantly higher than those in the TT group ( P <0.05)., Conclusion: The early effectiveness of ACL reconstruction by using the I.D.E.A.L technique is better, the knee joint is more stable, and the incidence of postoperative complication is lower. However, the maturity of the graft after reconstruction using the TT technique is higher.

Rationale and Objectives: There are currently no studies investigating the in vivo stiffness of the most commonly used autografts for anterior cruciate ligament reconstruction (ACLR) using Shear wave elastography (SWE). We hypothesize that there are differences regarding the elastic properties between the three tendons commonly used for ACLR and that they are influenced by patient-related factors., Materials and Methods: 80 healthy subjects (25 females, 55 males, age: 25.33 ± 4.76 years, BMI: 23.76 ± 3.14 kg/m 2 , 40 semiprofessional athletes, athlete group [AG], age: 25.51 [19-29]; 40 healthy controls, control group [CG], age: 25.50 [20-29]) were recruited as participants. In addition to patient reported outcome scores, every participant underwent a standardized multimodal ultrasound protocol consisting of B-mode-ultrasound (B-US), Color Doppler-ultrasound (CD-US) and a SWE examination of the bilateral quadriceps tendon (QT), patellar tendon (PT) and semitendinosus tendon (ST)., Results: The highest shear wave velocity (SWV) were observed in ST (4.88 (4.35-5.52) m/s, ST vs QT, p = 0.005; ST vs PT, p < 0.001) followed by QT (4.61 (4.13-5.26) m/s, QT vs PT, p < 0.001) and PT (3.73 (3.30-4.68) m/s). Median QT, PT and ST stiffness was significantly higher in AG compared to CG. Male subjects tend to have stiffer QT and PT than female subjects. Positive correlation with SWV was obtained for age and activity level., Conclusion: There are significant differences regarding in vivo tendon stiffness between the most frequently used autograft tendon options for ACLR. The quantitative information obtained by SWE could be of particular interest for graft choice for ACLR., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Association of University Radiologists.

Introduction: The purpose of this prospective study was to report the outcomes of two different methods in CC and AC reconstruction for the treatment of AC separation using a tendon graft and knot-hiding titanium clavicular implant., Materials and Methods: Twenty-seven patients with Rockwood grade III and V acromioclavicular (AC) separations were randomized into two groups. The primary outcome was whether taking the tendon graft through the coracoid risked a fracture. The following were secondary outcomes: follow-up of clavicular wound healing and Nottingham Clavicle score, Constant score, and Simple Shoulder Test results obtained preoperatively and 24 months postoperatively. The anteroposterior radiographic change between the clavicular and coracoid cortexes and the clavicular tunnel diameter was measured postoperatively and 24 months postoperatively. General patient satisfaction with the outcome (poor, fair, good, or excellent) was assessed 2 years postoperatively., Results: No coracoid fractures were detected. No issues in clavicular wound healing were detected. The mean Nottingham Clavicle score increased from a preoperative mean of 42.42 ± 13.42 to 95.31 ± 14.20 (P < 0.00). The Constant score increased from a preoperative mean of 50.81 ± 17.77 to 96.42 ± 11.51 (P < 0.001). The Simple Shoulder Test score increased from a preoperative mean of 7.50 ± 2.45 to 11.77 ± 1.18 (P < 0.001). The changes were significant. The coracoclavicular distance increased from 11.88 ± 4.00 to 14.19 ± 4.71 mm (P = 0.001), which was significant. The clavicular drill hole diameter increased from 5.5 to a mean of 8.00 ± 0.75 mm. General patient satisfaction was excellent., Conclusions: There were no significant differences between the two groups. There were no implant related complications in the clavicular wound healing.

Importance: Bibliometric research is a statistical analysis of publications to measure the scientific output in a specific field in order to highlight medical developments or knowledge gaps and to direct future scientific research. The quantity of orthopedic papers on the internet is astounding and is steadily growing as a result of recent advancements in technology and medicine. This is why choosing the right information is essential., Aim: The purpose of this study was to analyze the current literature for trends in publications regarding quadriceps tendon (QT) grafting of the anterior cruciate ligament (ACL)., Evidence Review: PubMed was searched on August 28, 2023. References were collected from PubMed, and trends were analyzed using this information. This search retrieved 405 articles regarding human and animal studies. We analyzed the top 10 authors and journals in terms of publication numbers, citation numbers, and citations per year. The PubMed-by-year feature was used to compare the number of publications regarding ACL reconstruction by quadriceps grafting with all publications in PubMed., Findings: The number of yearly publications averaged 10 or less up to 2018, starting from 1982 when the first paper on the QT was published. However, the number of publications increased from 2018. While the total number of publications on this topic was 405, 260 were published from 2018 alone. The number of citations was 8262 in total overall years. It is expected that the last five years' publications, especially those for the last year, will be low in number, as it takes time for citations to accrue. The journal Arthroscopy published the most articles on this topic, with 57 papers and 1884 citations, followed by the American Journal of Sports Medicine, with 39 articles and 1576 citations. The top three journals on this topic were Arthroscopy, AmericanJournalofSportsMedicine, and KneeSurgery, SportsTraumatology, Arthroscopy. The most published author was Musahl V (with 24 articles), and the most cited author was Xerogeanes JW (with 570 citations)., Conclusions and Relevance: Global trend analysis suggests that research on anterior cruciate ligament reconstruction with the quadriceps has significantly increased in the last 5 years and that the number of papers on this topic is increasing steadily. We found that the publications and citations are exhibiting a rising trend, Arthroscopy is the most impactful journal, and Musahl V is the most impactful author on the topic. Xerogeanes JW is the author with the most citations on the topic. The promising clinical results of anterior cruciate ligament reconstruction with the QT have attracted the most research interest., Level of Evidence: Level IV., (Copyright © 2024 The Author(s).

This study aimed to test and compare the biomechanical properties of three tibial fixation methods of anterior cruciate ligament (ACL) tendon grafts under cyclic load and load-to-failure testing in the bovine proximal tibiae, comprising (1) staple fixation alone, (2) interference screw fixation alone, and (3) interference screw fixation with a supplementary staple. Twenty-four bovine tibiae used in the study were divided into three groups (eight proximal tibiae in each group) based on tibial fixation methods of ACL tendon grafts: group A (a spiked ligament staple alone), group B (a cannulated interference screw alone), and group C (a cannulated interference screw with a supplementary staple). Each graft fixation was exposed to cyclic loading conditions. Significant differences were determined in failure load among the three groups ( p  = 0.008). The mean failure load was significantly higher in group B (717.04 ± 218.51 N) than in group A (308.03 ± 17.22 N) ( p  = 0.006). No significant differences were observed among the groups regarding axial stiffness ( p  = 0.442). Cyclic displacement differed significantly among the three groups ( p  = 0.005). In pairwise comparisons, the mean cyclic displacement was significantly higher in group A (8.22 ± 3.24 mm) compared with group C (1.49 ± 0.41 mm) ( p  = 0.005). Failure displacement varied considerably among the groups ( p  = 0.037). Although group B (15.53 ± 6.43 mm) exhibited a greater mean failure displacement than both group A (4.9 ± 0.75 mm) and group C (8.84 ± 4.65 mm), these differences did not reach statistical significance ( p  = 0.602 and p  = 0.329, respectively). Interference screw fixation alone and supplementary staple fixation have biomechanically similar characteristics in terms of initial strength and stiffness of tibial ACL soft tissue graft fixation. Regardless of staple use, an interference screw with the same diameter as the tibial tunnel can ensure sufficient tensile strength in tibial ACL graft fixation., Competing Interests: None declared., (Thieme.

Background: The ideal graft for anterior cruciate ligament (ACL) reconstruction (ACLR) in young athletes has a high return-to-sport (RTS) rate and a low reinjury rate. Quadriceps tendon autografts are being used with increasing frequency for ACLR in this population, despite a paucity of evidence to support their use., Purpose: To report the RTS rate, ipsilateral reinjury rate, and contralateral ACL injury rate in a young athletic population undergoing primary ACLR using an all-soft tissue quadriceps tendon (ASTQT) autograft., Study Design: Cases series; Level of evidence, 4., Methods: Patients aged 14 to 22 years who underwent primary ACLR using an ASTQT autograft by a single surgeon between January 1, 2005, and April 30, 2020, were identified via electronic medical records and contacted ≥24 months after ACLR to complete a survey regarding subsequent ipsilateral or contralateral ACL injuries and RTS. Patients who had undergone previous ACLR (ipsilateral or contralateral) were excluded., Results: A total of 656 patients (330 male, 326 female; mean age, 17.9 years) were identified, and 395 patients completed the survey (60.2%; 174 male, 221 female; mean age, 17.8 years) with a mean follow-up of 73 ± 29 months (range, 24-139 months). The RTS rate was high (male: 87.7%; female: 82.8%; P = .19). Male and female patients had similar rates of revision ACLR (male: 12.6%; female: 10.0%; P = .40) and contralateral ACL injuries (male: 13.8%; female: 11.3%; P = .46)., Conclusion: A high RTS rate and similar rates of ipsilateral and contralateral ACL injuries were found for male and female patients in a young athletic population undergoing primary ACLR using an ASTQT autograft. These results help one to better understand the utility of ASTQT grafts to support successful ACLR in young athletic populations, for which ASTQT grafts appear to yield favorable outcomes., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: H.S. has received support for education from Peerless Surgical and Evolution Surgical and travel expenses from Arthrex.

Purpose: Fresh-frozen specimen availability and cost may be a barrier for initiation of biomechanical studies where soft tissue is used in a construct with other medical devices. The impact of soft tissue preservation method on the outcomes of biomechanical studies in the specific case of graft-suture constructs is relatively unexplored. This study aimed to observe peak loads and failure modes in biomechanical testing of fresh-frozen (FF) versus formalin embalmed (FE) quadriceps tendon (QT) graft-suture constructs for soft tissue fixation in ACLR and assess suitability of FE QT graft constructs for load-to-fail testing., Methods: Twenty QT grafts were harvested from human cadaver specimens. Ten grafts came from fresh-frozen donors and 10 from embalmed donors. All grafts were prepared with the modified Prusik knot using a braided composite suture and subjected to tensile loading. Comparisons between the biomechanical properties of the graft-suture constructs were made with unpaired t tests with α = 0.05., Results: FE and FF constructs displayed similar peak loads and failure modes. FF constructs had greater elongation after pre-tensioning than FE (7.3 vs. 5.5 mm, p = 0.02) and greater elongation after cyclic loading than FE constructs (17.5 vs. 10.5 mm, p = 0.01). Hysteresis was greater for FF constructs at the 50th, 100th, 150th, and 200th cycle (p = 0.02, p = 0.07, p < 0.001, p = 0.004, respectively). FE constructs were stiffer than fresh-frozen (103 vs. 84 N/mm, p < 0.001)., Conclusion: FE constructs were significantly stiffer but displayed similar peak load and failure mode to FF which was reflective of the strength of the suture material. FE grafts can offer an alternative to FF grafts in graft-suture constructs for biomechanical studies where load at failure and knot security and strength is of main interest., (© 2024.

Background: Anterior cruciate ligament reconstruction (ACLR) is most commonly performed with hamstring tendon (HT) or bone-patellar tendon-bone (BTB) autografts, although the quadriceps tendon (QT) autograft has recently increased in popularity. This systematic review and meta-analysis review compares QT and HT autografts for primary ACLR with a sole focus on randomised controlled trials (RCTs)., Methods: A prospective protocol was registered on PROSPERO (CRD42023427339). The search included MEDLINE, Embase and Web of Science until February 2024. Only comparative RCTs were included. The primary outcome was the International Knee Documentation Committee (IKDC) Subjective Knee Evaluation Form score. Secondary outcomes included: other validated patient-reported outcome measures (PROMs), objective strength scores, complications, and return to sport and work., Results: From 2,609 articles identified, seven were included (n = 474 patients). This meta-analysis did not identify a significant difference in post-operative IKDC scores (5 articles; p = 0.73), Lysholm scores (3 studies; p = 0.80) or Tegner activity scales (2 studies; p = 0.98). There were no differences in graft failure rates (4 studies; p = 0.92) or in overall adverse events (4 studies; p = 0.83) at 24 months post-ACLR as per meta-analysis. Donor site morbidity scores were significantly lower in the QT group (MD -4.67, 95% CI -9.29 to -0.05; 2 studies, 211 patients; p = 0.05, I 2  = 34%)., Conclusion: There were no differences between QT and HT in PROMs, graft failure rates or overall complications based on low- to moderate-quality evidence. There may possibly be lower donor site morbidity with the QT autograft, however, the evidence is not sufficient to draw definitive conclusions., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Purpose: To retrospectively compare strength outcomes of individuals undergoing postoperative rehabilitation following quadriceps tendon (QT) autograft anterior cruciate ligament reconstruction (ACLR) with and without blood flow restriction therapy., Methods: A retrospective review of consecutive patients undergoing ACLR with QT autograft with a minimum of two quantitative postoperative isometric strength assessments via an electromechanical dynamometer (Biodex) was included. Demographics, surgical variables and strength measurement outcomes were compared between patients undergoing blood flow restriction therapy as part of postoperative rehabilitation versus those who did not., Results: Eighty-one (81) patients met the inclusion criteria. No differences were found in demographic and surgical characteristics between those who received blood flow restriction compared with those who did not. While both groups had improvements in quadriceps peak torque and limb symmetry index (LSI; defined as peak torque of the operative limb divided by the peak torque of the nonoperative limb) over the study period, the blood flow restriction group had significantly lower mean peak torque of the operative limb at first Biodex strength measurement (95.6 vs. 111.2 Nm; p = 0.03). Additionally, the blood flow restriction group had a significantly lower mean LSI than those with no blood flow restriction at the second Biodex measurement timepoint (81% vs. 90%; p = 0.02). No other significant differences were found between the strength outcomes measured., Conclusions: Results of this study show that the 'real world' clinical implementation of blood flow restriction therapy to the postoperative rehabilitation protocol following QT autograft ACLR did not result in an increase in absolute or longitudinal changes in quadriceps strength measurements. A better understanding and standardisation of the use of blood flow restriction therapy in the rehabilitation setting is necessary to delineate the true effects of this modality on strength recovery after QT autograft ACLR., Level of Evidence: Level III., (© 2024 European Society of Sports Traumatology, Knee Surgery and Arthroscopy.)

Introduction: Peroneus longus has proved to be a promising graft for ACL reconstruction due to its high tensile strength, and ease of harvesting. While multiple studies have assessed the functional outcomes of the knee after ACL reconstruction using peroneus longus autograft, we aimed to evaluated donor site morbidity among the Indian population., Matreials and Methods: This was a prospective, longitudinal, descriptive study conducted at a tertiary care hospital. Preoperative AOFAS and Karlsson-Peterson scores were obtained, and patients were followed up after surgery for a period of 6-months using the same scoring systems and strength testing with a hand-held Chatillon MSE-100-M dynamometer. Pedobarographs were done using Diers Pedoscan Plantar Pressure Measurement System on a subset of seven patients., Results: 20 patients participated in the study. Mean AOFAS and Karlsson-Peterson scores pre-operatively were 99.7 ± 1.34 and 98.5 ± 4.62 respectively. On completing 6- months of follow-up these scores were found to be 95.6 ± 9.43 and 88.75 ± 18.42 respectively. Deterioration of mean evertor strength was noted at all follow-ups compared to the opposite side. Static pedobarographs showed significant decreased in total surface area of contact and pressure over the posterior aspect of the operated side by 3-months which improved later at 6-months. Dynamic pedobarographs showed decreased mean average plantar pressure while walking on the operated side and significant increase in mean surface area of contact of the operated side (191.886±22.678 cm 2 ) at 6-months of follow-up compared to the opposite side (184.471 ± 22.218 cm 2 ). Five patients showed deviation of the point of maximum pressure while walking on the operated foot making it lateral to the COP with increased lateral plantar/ medial plantar pressure ratio., Conclusion: While the use of peroneus longus tendon autografts in arthroscopic ACL reconstruction does not seem problematic on short-term subjective assessment, there is objective evidence in keeping with evertor weakness, weakness of first ray plantar flexion and possible ankle instability., Level of Evidence: Level lll., (© 2024.

Purpose: To assess the validity and informational value of teaching material regarding anterior cruciate ligament reconstruction (ACLR) using quadriceps tendon (QT) autograft provided on the YouTube video platform., Methods: An extensive systematic search of the YouTube video platform was performed, and all videos that met the criteria were included in the analysis. The analysis of the video content was performed using the DISCERN instrument, Journal of American Medical Association (JAMA) benchmark criteria, and Global Quality Score (GQS). The duration of the videos, the date of publication, and the number of likes and views were recorded. Furthermore, videos were categorized based on the source (physicians, companies, patients), the subject (surgical technique, patient experience and overview [overview videos were videos in which multiple aspects were analyzed]), and the type of content (educational or subjective patient experience)., Results: A total of 88 videos were included in the analysis. Seventy-one (80.7%) videos were published by physicians, 15 (17.0%) by patients, and 2 (2.3%) by companies. The majority of the videos described various surgical techniques (59%-67.0%), 80.7% of the videos (72%-81.8%) had an educational nature, and the remaining 18.2% described patient experiences. The mean length of the videos was 8.21 ± 7.88 minutes. The mean number of views was 3,988.51 ± 9,792.98 (range 9-56,047), whereas the mean numbers of comments and likes were 30.07 ± 70.07 (range 0-493) and 4.48 ± 14.22 (range 0-82), respectively. The mean DISCERN score, JAMA score, and GQS were 27.43 ±11.56 (95% confidence interval [CI] 25.01-29.85; range: 17-68), 1.22 ± 0.85 (95% CI 1.04-1.40; range 0-3), and 1.82 ± 0.93 (95% CI 1.63-2.01; range 1-4), respectively. For all scores, videos published by physicians had greater quality (DISCERN score, JAMA score, and GQS) (P < .05). Among all of the analyzed videos, overview videos were of the highest quality (P < .05)., Conclusions: YouTube is a fast and open-access source of mass information. The overall quality of the videos on ACLR performed using QT autograft was unsatisfactory, demonstrating low educational quality and reliability. Currently, YouTube cannot be recommended as a reliable source of information on ACLR with the QT., Clinical Relevance: Surgeons treating anterior cruciate ligament injuries should take special care when suggesting outside sources for patients to use to further educate themselves about this procedure. Due to the poor quality of the content, orthopaedic health care professionals should alert patients about the inaccuracies of YouTube videos addressing anterior cruciate ligament reconstruction with the quadriceps tendon. Additionally, health care practitioners should attempt to offer patients better options., Competing Interests: Disclosures The authors report no conflicts of interest in the authorship and publication of this article.

Case: A 14-year-old adolescent girl and 18-year-old man underwent right anterior cruciate ligament (ACL) reconstruction using quadriceps tendon (QT) autografts via partial-thickness harvest. While both patients initially recovered well, later they experienced a painful snapping in their knee localized to the lateral QT, just proximal to the patella. Surgical completion of the previous partial-thickness defect with imbrication provided resolution of symptoms at 4 and 9 months postoperatively, respectively., Conclusion: We present a snapping QT as a rare complication of partial-thickness QT harvest for ACL reconstruction. Surgical completion of the partial-thickness defect with imbrication resolved the snapping sensation in these two cases., Competing Interests: Disclosure: The Disclosure of Potential Conflicts of Interest forms are provided with the online version of the article (http://links.lww.com/JBJSCC/C394)., (Copyright © 2024 by The Journal of Bone and Joint Surgery, Incorporated.)

The hamstring tendon (HT) autograft is currently the most widely utilised autograft option for anterior cruciate ligament (ACL) reconstruction. However, recent studies endorse the peroneus longus tendon (PLT) autograft as a viable alternative. To evaluate this, we systematically reviewed randomised controlled trials (RCTs) to compare the efficacy of PLT against HT autografts. Our search encompassed Cochrane, Embase, OVID, PubMed, and Scopus databases for RCTs comparing outcomes of PLT and HT autografts in ACL reconstruction. Primary outcomes included Lysholm and International Knee Documentation Committee (IKDC) scores, while secondary outcomes involved American Orthopaedic Foot and Ankle Society (AOFAS) scores, graft diameters and donor-site complications. Statistical analysis was performed using Review Manager 5.4 (Cochrane Collaboration) and heterogeneity was assessed with I 2 statistics. 683 patients from 6 RCTs were included, with 338 (49.5%) patients treated with PLT autografts. Follow-up ranged from 12 to 30 months. Despite lower preoperative Lysholm scores in the PLT group, no significant differences were observed at 6 and 12 months. Although preoperative and 6-month IKDC scores were lower in the PLT group, no significant differences were found at 12 and 24 months. AOFAS scores showed no significant preoperative difference, but slightly lower scores were noted in the PLT group at 12 or 24 months. There was no significant difference in graft diameter, while donor-site complications were fewer in the PLT group. In summary, the PLT autograft is a promising and non-inferior alternative to the HT autograft, demonstrating equivalent outcomes in patient-reported knee and ankle metrics, comparable graft diameters and fewer donor-site complications., (© 2024.

Background: The rate of anterior cruciate ligament (ACL) rupture in active, skeletally immature patients is increasing. Although hamstring tendon autograft (HTA) was previously deemed the gold standard, recent studies have shown HTA to have a high failure rate in this high-risk population of young competitive athletes, and quadriceps tendon autograft (QTA) has yielded excellent preliminary outcomes in some studies examining this population., Purpose: To evaluate 3-year clinical and patient-reported functional outcomes of primary ACL reconstruction (ACLR) with soft tissue QTA in skeletally immature patients., Study Design: Case series; Level of evidence, 4., Methods: Skeletally immature patients who underwent ACLR with a full-thickness soft tissue QTA were included. Preoperative patient and surgical data were collected. The ACLR technique was selected predicated upon skeletal age and included all-epiphyseal and complete transphyseal techniques. Patients were followed for a minimum of 2 years with successive clinical visits or were contacted via telephone. Patients who did not have minimum 2-year follow-up after 3 contact attempts via telephone were excluded. Information regarding return to sports (RTS) and concomitant or subsequent surgical procedures was collected. Pediatric International Knee Documentation Committee (Pedi-IKDC), Hospital for Special Surgery Functional Activity Brief Scale (HSS Pedi-FABS), and Single Assessment Numeric Evaluation (SANE) scores were collected., Results: Of 85 adolescent patients aged 11.1 to 17.6 years (mean age, 14.1 ± 1.2 years), 2 patients were determined to be lost to follow-up after 3 failed contact attempts. Of the patients included in this study (N = 83), 26 patients (31%) underwent all-epiphyseal and 57 patients (69%) underwent complete transphyseal ACLR. Additionally, 48 patients (58%) underwent concomitant lateral extra-articular tenodesis using the iliotibial band with a modified Lemaire technique. The mean follow-up time was 3.7 ± 1.2 years (range, 2-7 years). Twenty (24%) patients had subsequent surgical procedures, of which 3 (4%) were due to graft failures. At a mean 3-year follow-up, the mean Pedi-IKDC, HSS Pedi-FABS, and SANE scores were 90, 23, and 94 respectively; the RTS rate was 100%; and the rate of RTS at the previous level of performance was 93%., Conclusion: Use of a soft tissue QTA for ALCR in a high-risk skeletally immature population of athletes resulted in excellent postoperative outcomes with low rates of graft failure and high return to sport rates., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: F.A.C. has received royalties from Arthrex, Saunders Mosby Elsevier, and Wolters-Kluwer Health Lippincott Williams and Wilkins; consulting fees from Arthrex; and support for education from Gotham Surgical Solutions & Devices.

Purpose: Management of massive rotator cuff tears (MRCTs) remains debated, and various arthroscopic and open techniques have been described for their management. Nevertheless, the optimal strategy remains unclear. The present study evaluated the clinical results in patients managed arthroscopically for MRCTs augmented with the long head biceps tendon (LHBT) at a minimum 1-year follow-up, considering different type of tears, demographic data and number of torn tendons., Methods: Patients treated in a secondary referral centre from January 2021 to April 2022 were enroled prospectively. Inclusion criteria were pain, inability to fully elevate the affected shoulder, irreparable tears and active and motivated patients. All patients were managed within 2 months from diagnosis in a single centre by the same surgeons. Preoperative shoulder radiographs and magnetic resonance imaging (MRI) were collected, and clinical assessment was also performed using the Numerical analogue scale (NAS), Constant score (CS) American Shoulder and Elbow Surgeons Shoulder Score (ASES). Tissue retraction and tendon fatty infiltration were evaluated using Patte and Fuchs scale, respectively. Clinical assessment was performed using the same scales at 3-6 months and 1-year follow-up., Results: A total of 55 patients (31 female and 24 male) with a mean age of 60 ± 7.1 years were enroled for a mean follow-up of 18.2 ± 4.3 months. The mean preoperative NAS was 7.8 ± 0.6, CS was 20.5 ± 7.6 and ASES was 22.6 ± 9.2, increasing, respectively, to 0.3 ± 0.6, 91.5 ± 6.9 and 94.2 ± 6.7. No adverse side effects (infection, rejection, allergy) were reported during the study period. All patients were evaluated after surgery at 3 and 6 months and 1 year with statistically significant improvement for each score at the first and last follow-up (p < 0.05)., Conclusions: The use of LHBT augmentation in patients with MRCTs in appropriately selected patients is safe and effective and can lead to pain relief and acceptable clinical outcomes. Furthermore, its use carries low donor site morbidity and is cost effective. Comparative studies, including randomised controlled trials, with other proposed techniques are needed to confirm these findings., Level of Evidence: Level IV., (© 2024 European Society of Sports Traumatology, Knee Surgery and Arthroscopy.)

Purpose: We describe a surgical technique for ACL reconstruction combined with anterolateral structure reinforcement and report early clinical follow-up results., Methods: The semitendinosus and gracilis tendons are braided into 5 strands and the ACL femoral tunnel and tibial tunnel are created. The graft is passed through the tunnel with the use of a traction suture and the tibial end is fixed with absorbable interference screws at 30° of knee flexion. The ACL graft traction suture is used as an anterolateral reconstruction structure to pass through the proximal exit of the ACL femoral tunnel and then through the depth of the iliotibial bundle to the anterior to Gerdy's tubercle, a bony tunnel is created from the anterior to Gerdy's tubercle to the goose foot, and the traction suture is passed through this bony tunnel to form a Loop structure at 20° of knee flexion. Between March 2021 and May 2022 IKDC score, Lysholm score, and Tegner score were performed preoperatively and 6-12 months postoperatively in 24 consecutive patients who met the indications for this procedure and underwent surgery. The patient's maximum flexion angle, the circumference of the thigh, and the stress X-ray between the operated and healthy knee were measured., Results: Patients showed significant improvement in IKDC score, Lysholm score and Tegner score at a mean follow-up of 7 months postoperatively compared to preoperatively. No significant increase in anterior tibial displacement was found between the patient's operated side and the healthy side., Conclusion: The Loop technique ACLR combined with ALSA can be used in patients with an ACL tear combined with a high degree of positive pivot shift. The patient's subjective perception was significantly improved from the preoperative period and knee stability was restored., Level of Evidence: IV, therapeutic study., (© 2024. The Author(s).)

Introduction: Multiligament knee injury with posteromedial laxity is serious and usually requires surgery. Reconstruction is preferable to repair. The main aim of the present study was to report clinical results and laximetry for an original posteromedial corner (PMC) allograft reconstruction technique known as The Versailles Technique. The secondary aim was to determine prognostic factors for surgery. The study hypothesis was that anatomic PMC reconstruction by tendon allograft provides satisfactory medium-term clinical and laximetric results., Methods: A retrospective study assessed postoperative clinical and laximetric results after PMC allograft reconstruction at a minimum 12 months' follow-up. Laxity was assessed on comparative bilateral stress X-rays, and functional results on the International Knee Documentation Committee (IKDC) score, the Lysholm score and the Knee injury and Osteoarthritis Outcome Score (KOOS)., Results: Twenty-six patients were included between 2013 and 2019. Mean follow-up was 27.4±9 months. Mean subjective IKDC score was 69.21±17.36, mean Lysholm score 77.78±14.98 and mean KOOS 66.44±18.52., Objective: IKDC results were 77% grade A, 22% grade B, and 0% grade C or D. Mean medial differential laxity in forced varus was 0.83±1.26mm. Mean subjective IKDC scores were poorer in Schenck KD-III than KD-I (p=0.03). Functional results were comparable with acute and with chronic laxity. Age correlated inversely with median KOOS (p=0.009). There was no correlation between postoperative radiologic laxity in forced varus and functional results., Discussion: Versailles anatomic PMC allograft reconstruction for acute or chronic posteromedial knee laxity showed medium-term efficacy in restoring good objective and subjective stability., Level of Evidence: IV; retrospective observational study., (Copyright © 2024 Elsevier Masson SAS.

Purpose: The use of peroneus longus tendon (PLT) autografts in primary anterior cruciate ligament reconstruction (ACLR) has increased recently, but there is a lack of research on its use in revision ACLR. This study aimed to compare the clinical outcomes and complications between revision ACLR using allografts and PLT autografts., Materials and Methods: Fifty-nine patients who underwent arthroscopic revision of ACLR with complete clinical follow-ups between 2012 and 2021 were retrospectively reviewed. Allograft was used in 44 of these patients, and PLT autograft was used in 15 of them. Lysholm knee score, Tegner activity score, Lachman, and anterior drawer tests were performed after a mean follow-up of 60months (range: 19-116). The American Orthopaedic Foot and Ankle Society (AOFAS) scale was used to evaluate the donor ankle functions. Clinical outcomes and complications were compared between groups., Results: Both groups showed significantly improved functional outcomes compared to their preoperative assessments. However, both groups had similar clinical results at the final follow-up, including Lysholm knee score, Tegner activity scale, knee range of motion, return to sports, time to return to daily activities, and rate of re-rupture. No major complications were seen in any of the patients. The AOFAS score was 99.13±2.64 in the PLT autograft group without loss of ankle muscle strength, deformity, instability, and permanent iatrogenic neurovascular injuries. The cumulative cost of the allograft group was significantly higher than the PLT autograft group., Conclusions: The PLT autograft might be an alternative autograft option to allografts due to similar clinical outcomes, low donor site morbidity, and reduced cost in ACLR revisions, especially if the primary ACLR was performed using grafts harvested around the knee., Level of Evidence: III; retrospective comparative study., (Copyright © 2023.

Objective: Peroneus Longus Tendon (PLT), a viable anterior cruciate ligament (ACL) graft, shares similar biomechanics, making it suitable for reconstruction. Controversy exists over whether PLT transplants affects the donor ankle joint. The purpose of this study was to examine the recovery of knee joint function following arthroscopic ACL restoration using autologous PLT and its influence on the donor ankle joint., Methods: A retrospective analysis was conducted on 65 patients with ACL rupture who underwent PLT graft reconstruction in our hospital from January 2016 to December 2021. A three-dimensional gait analysis of the bilateral knee and ankle joints was performed postoperatively using an Opti&#95;Knee three-dimensional motion measurement and analysis system-Yidong Medical Infrared Motion Gait Analyzer. Knee function scores and changes in the range of motion of the bilateral knee and ankle joints were collected. The analysis of preoperative and postoperative joint function scores, bilateral knee and ankle mobility was performed by t-tests., Results: One year after surgery, the patients' International Knee Documentation Committee (IKDC) scores, Knee Injury and Osteoarthritis Outcome Scores (KOOSs), and Lysholm scores were significantly improved compared to preoperative scores, with statistically significant differences (p < 0.05). There was no statistical difference in the American Orthopedic Foot and Ankle Society (AOFAS) score of the donor ankle joint before and after surgery (p > 0.05). During different gait cycles, there was no statistical difference in knee joint mobility between the affected and healthy sides (p > 0.05), but there was a statistical difference in the inversion and eversion angle of the donor ankle joint during the support phase (p < 0.05)., Conclusion: ACL reconstruction using the PLT can yield satisfactory knee joint function. However, it does affect inversion and eversion in the donor ankle joint, necessitating postoperative exercises. Similar subjective function ratings for both operated and non-operated feet, despite increased inversion-eversion motion in the operated foot, may be influenced by the subjective nature and margin of error in the AOFAS Ankle-hindfoot score, along with the relatively small variation in ankle inversion-eversion angles., (© 2024 The Authors.

Background: The indirect head of the rectus femoris (IHRF) tendon has been used as an autograft for segmental labral reconstruction. However, the biomechanical properties and anatomic characteristics of the IHRF, as they relate to surgical applications, have yet to be investigated., Purpose: To (1) quantitatively and qualitatively describe the anatomy of IHRF and its relationship with surrounding arthroscopically relevant landmarks; (2) detail radiographic findings pertinent to IHRF; (3) biomechanically assess segmental labral reconstruction with IHRF, including restoration of the suction seal and contact pressures in comparison with iliotibial band (ITB) reconstruction; and (4) assess potential donor-site morbidity caused by graft harvesting., Study Design: Descriptive laboratory study., Methods: A cadaveric study was performed using 8 fresh-frozen human cadaveric full pelvises and 7 hemipelvises. Three-dimensional anatomic measurements were collected using a 3-dimensional coordinate digitizer. Radiographic analysis was accomplished by securing radiopaque markers of different sizes to the evaluated anatomic structures of the assigned hip.Suction seal and contact pressure testing were performed over 3 trials on 6 pelvises under 4 different testing conditions for each specimen: intact, labral tear, segmental labral reconstruction with ITB, and segmental labral reconstruction with IHRF. After IHRF tendon harvest, each full pelvis had both the intact and contralateral hip tested under tension along its anatomic direction to assess potential site morbidity, such as tendon failure or bony avulsion., Results: The centroid and posterior apex of the indirect rectus femoris attachment are respectively located 10.3 ± 2.6 mm and 21.0 ± 6.5 mm posteriorly, 2.5 ± 7.8 mm and 0.7 ± 8.0 mm superiorly, and 5.0 ± 2.8 mm and 22.2 ± 4.4 mm laterally to the 12:30 labral position. Radiographically, the mean distance of the IHRF to the following landmarks was determined as follows: anterior inferior iliac spine (8.8 ± 2.5 mm), direct head of the rectus femoris (8.0 ± 3.9 mm), 12-o'clock labral position (14.1 ± 2.8 mm), and 3-o'clock labral position (36.5 ± 4.4 mm). During suction seal testing, both the ITB and the IHRF reconstruction groups had significantly lower peak loads and lower energy to peak loads compared with both intact and tear groups ( P = .01 to .02 for all comparisons). There were no significant differences between the reconstruction groups for peak loads, energy, and displacement at peak load. In 60° of flexion, there were no differences in normalized contact pressure and contact area between ITB or IHRF reconstruction groups ( P > .99). There were no significant differences between intact and harvested specimen groups in donor-site morbidity testing., Conclusion: The IHRF tendon is within close anatomic proximity to arthroscopic acetabular landmarks. In the cadaveric model, harvesting of the IHRF tendon as an autograft does not lead to significant donor-site morbidity in the remaining tendon. Segmental labral reconstruction performed with the IHRF tendon exhibits similar biomechanical outcomes compared with that performed with ITB., Clinical Relevance: This study demonstrates the viability of segmental labral reconstruction with an IHRF tendon and provides a detailed anatomic description of the tendon in the context of an arthroscopic labral reconstruction. Clinicians can use this information during the selection of a graft and as a guide during an arthroscopic graft harvest., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: Stryker donated the suture anchors used in the study.

Introduction: Only a few anatomic studies have described an isolated rectus femoris tendon autograft for anterior cruciate ligament (ACL) reconstruction. This study aims to demonstrate a new surgical technique utilising the rectus femoris tendon for ACL reconstruction. This study hypothesises that the rectus tendon autograft will yield satisfying postoperative outcomes in terms of stability, with minimal complications at the harvest site., Methods: This retrospective study investigated the outcomes of 28 revision ACL reconstructions using a rectus tendon autograft with a mean follow-up of 41.7 (range, 24.0-64.8) months. A 3 cm longitudinal incision was used to harvest the rectus tendon with an open tendon stripper. Intraoperative collected data included the length of the tendon and thickness of a 4-fold graft. Further outcome parameters include anterior cruciate ligament stability and range of motion. Additionally, postoperative complications, especially donor site morbidity, were documented in type and frequency., Results: The mean tendon length measured 32.4 cm (range, 30-35 cm). After preparing a 4-fold graft, the mean diameter was 9.2 mm (range, 8.0-10 mm) at the tibial and 9.0 mm (range, 7.5-10 mm) at the femoral end. Stability evaluated by the Lachman test improved significantly from 2 (Interquartile range (IQR), 2-3) preoperatively to 0 (IQR, 0-1) postoperatively (p < .001). Rerupture of the anterior cruciate ligament graft was observed in 2 patients (7.1%). Four patients showed a persistent extension deficit of about 5 degrees postoperatively. Two of them underwent revision surgery due to a Cyclops lesion. Only one patient complained of prolonged pain at the harvest site (3.6%)., Conclusion: The 4-fold rectus tendon represents a novel autograft technique in revision ACL reconstruction. This study provides evidence of appropriate graft dimensions and satisfying postoperative outcomes regarding stability. The technique is associated with a low complication rate at the harvest site., Study Design: Case series; Level of evidence, IV., (© 2024.

Objectives: This study aimed to report surgical technique and clinical outcomes for a novel figure-of-eight collateral ligament reconstruction technique using palmaris longus autograft for chronic irreparable collateral ligament injury of the thumb metacarpophalangeal joint., Material and Methods: The Jobe elbow collateral ligament reconstruction method was adapted for thumb metacarpophalangeal joint collateral ligament reconstruction. Sixteen reconstructions (7 ulnar collateral ligament, 9 radial collateral ligament) using palmaris longus autograft were reviewed retrospectively. Surgery was performed at a mean 12 months post-injury. All 16 patients were followed up for more than 1 year. Metacarpophalangeal joint radial and ulnar deviation, metacarpophalangeal and interphalangeal joint range of motion, key pinch and grip strength, Glickel functional grade and QuickDASH score were evaluated., Results: Preoperative radial or ulnar deviation improved from 19.3° to 5.3° postoperatively. Metacarpophalangeal range of motion improved from 31.5° to 46.6°, and interphalangeal range of motion from 48.4° to 65.6°. Preoperative key pinch and grip strength were respectively 49% and 81% of contralateral values and improved to 82% and 87%. On Glickel grade, 9 cases were excellent and 7 good., Conclusion: The novel Jobe-like figure-of-eight reconstruction technique using palmaris longus graft was useful for reconstructing irreparable thumb metacarpophalangeal joint instability without an incision on the opposite side or an additional implant., Level of Evidence: Therapeutic study, level IV., (Copyright © 2024 SFCM.

Purpose: To evaluate and compare isokinetic knee muscle (extension and flexion) strength, single-leg hop (SLH) test performance, anterior knee laxity, subjective knee function, and the 2-year revision surgery risk between patients who underwent anterior cruciate ligament reconstruction (ACLR) with semitendinosus tendon (ST) autografts and patients who underwent ACLR with ST and gracilis tendon (ST-G) autografts., Methods: We identified patients aged 16 years or older who underwent primary ACLR with hamstring tendon autografts at our institution from January 2005 to December 2020 and had no associated ligament injuries. Isokinetic knee muscle strength and SLH test performance were assessed 6 months postoperatively. Anterior knee laxity (KT-1000 arthrometer, 134 N) was assessed preoperatively and 6 months postoperatively. The Knee Injury and Osteoarthritis Outcome Score (KOOS) was collected preoperatively and 1 and 2 years postoperatively. Patients who underwent revision ACLR at any institution in Sweden within 2 years of primary surgery were identified through the Swedish National Knee Ligament Registry., Results: A total of 6,974 patients (5,479 with ST and 1,495 with ST-G) were included. There were no significant differences in extension and flexion strength or SLH test performance between the groups. Preoperatively, there was no significant difference in knee laxity between the ST and ST-G groups. Postoperatively, the ST-G group had significantly increased mean side-to-side (STS) laxity (2.1 ± 2.3 mm vs 1.7 ± 2.2 mm, P < .001) and showed a trend toward increased STS laxity according to the International Knee Documentation Committee form, with significantly fewer patients with STS laxity of 2 mm or less (58.4% vs 65.8%) and significantly more patients with STS laxity between 3 and 5 mm (35.0% vs 29.9%) or greater than 5 mm (6.6% vs 4.3%) (P < .001). The only significant difference in subjective knee function was for the KOOS Quality of Life subscale score in favor of the ST group preoperatively (37.3 ± 21.4 vs 35.1 ± 19.9, P = .001). No other significant differences between the groups were found preoperatively and 1 and 2 years postoperatively for any of the KOOS subscales. The overall revision ACLR rate within 2 years of primary surgery was 2.0% (138 of 6,974 patients). The revision ACLR risk in the ST-G group (1.7%, 25 of 1,495 patients) was not significantly different from that in the ST group (2.1%, 113 of 5,479 patients) (hazard ratio, 0.80; 95% confidence interval, 0.50-1.24; P = .32)., Conclusions: The addition of the gracilis tendon to an ST autograft was not associated with knee muscle strength, SLH test performance, subjective knee function, or the risk of revision surgery after ACLR., Level of Evidence: Level III, retrospective comparative study., Competing Interests: Disclosures The authors report no conflicts of interest in the authorship and publication of this article.

Purpose: To evaluate the utility of semitendinosus tendon (ST) and gracilis tendon (GT) cross-sectional area (CSA) on magnetic resonance imaging (MRI) and anthropometric characteristics in preoperative estimation of graft diameter in patients undergoing anterior cruciate ligament reconstruction (ACLR) with four-strand hamstring autografts., Methods: Three databases were searched on 29 August 2023. The authors adhered to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) and R-AMSTAR (Revised Assessment of Multiple Systematic Review) guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. Data on demographics, anthropometric characteristics, imaging techniques, tendon CSA, correlation coefficients, sensitivities, specificities, regression models and cutoffs for predicting intraoperative graft diameters above 8 mm were recorded., Results: Forty-six studies comprising 4140 patients were included. Twelve of 19 (63.2%) studies reporting on ST + GT CSA found a moderate to very high correlation with intraoperative graft diameter. Five of 10 (50%) and one of seven (14.3%) studies reporting on ST CSA and GT CSA, respectively, found a moderate to high correlation with intraoperative graft diameter. Cutoffs of ST + GT CSA for predicting graft diameters above 8 mm ranged from 15.8 to 31.2 mm 2 . Nine of 35 (25.7%) studies that reported on height found a moderate to very high correlation with graft diameter. Seven of 33 (21.2%) studies reporting on weight found a moderate correlation with graft diameter., Conclusion: Of the MRI parameters assessed, ST + GT CSA was the most reliable predictor of graft diameter. However, cutoffs, sensitivities, and specificities for predicting diameters above 8 mm were highly variable. Anthropometric characteristics in general were less predictive of graft diameter than MRI parameters. This information can be used by clinicians to predict patients at risk for ACLR failure due to insufficient graft size., Level of Evidence: Level IV., (© 2024 The Authors.

Background: The vancomycin presoaking technique (wherein grafts are treated with a vancomycin solution [VS] for anterior cruciate ligament reconstruction [ACLR]) reduces the infection rate after ACLR. However, the effects of this technique on graft-bone healing have not been fully elucidated., Purpose: To investigate the effects of vancomycin presoaking on graft-bone healing in a rat ACLR model., Study Design: Controlled laboratory study., Methods: Long flexor digitorum longus tendons were obtained from 9 Wistar rats, and each was randomly allocated to the normal saline (NS) or VS groups. The grafts were immersed in sterile saline for 30 minutes in the NS group and in a 5-mg/mL VS in the VS group. The presence of time-zero graft bacterial contamination was confirmed, and the grafts were incubated in Fluidised Thioglycollate Broth for 2 weeks. ACLR was performed on the right knees of 65 male Wistar rats using the flexor digitorum longus tendons. Each graft was similarly treated. Biomechanical testing, micro-computed tomography, and histological evaluations were performed 4 and 12 weeks postoperatively., Results: The VS group showed significantly reduced graft contamination at time zero ( P = .02). The mean maximum loads to failure were 13.7 ± 8.2 N and 11.6 ± 4.8 N in the NS and VS groups, respectively, at 4 weeks ( P = .95); and 23.2 ± 13.2 N and 30.4 ± 18.0 N in the NS and VS groups, respectively, at 12 weeks ( P = .35). Regarding micro-computed tomography, the mean bone tunnel volumes were 3.76 ± 0.48 mm 3 and 4.40 ± 0.58 mm 3 in the NS and VS groups, respectively, at 4 weeks ( P = .41); and 3.51 ± 0.38 mm 3 and 3.67 ± 0.35 mm 3 in the NS and VS groups, respectively, at 12 weeks ( P = .54). Histological semiquantitative examination revealed no clear between-group differences at any time point., Conclusion: Presoaking grafts in vancomycin in a rat ACLR model demonstrated no discernible adverse effects on short- and midterm biomechanical, radiological, and histological investigations., Clinical Relevance: The findings provide guidance for surgeons when considering this technique., Competing Interests: One or more of the authors has declared the following potential conflict of interest or source of funding: This study was supported by the Japan Society for the Promotion of Science (22K16709).

Objective: To explore the early effectiveness and influence on cartilage of local injection of multimodal drug cocktail (MDC) during anterior cruciate ligament reconstruction (ACLR)., Methods: Between February 2022 and August 2023, patients undergone arthroscopic ACLR using autologous hamstring tendons were selected as the study subjects. Among them, 90 patients met the selection criteria and were randomly divided into 3 groups ( n =30) according to the different injection drugs after ligament reconstruction. There was no significant difference in baseline data such as gender, age, body mass index, surgical side, disease duration, preoperative thigh circumference, and preoperative levels of tumor necrosis factor α (TNF-α), interleukin 6 (IL-6), IL-1, matrix metalloproteinase 3 (MMP-3), MMP-13, and aggrecan (ACAN) in synovial fluid between groups ( P >0.05). After the ligament reconstruction during operation, corresponding MDC (consisting of ropivacaine, tranexamic acid, and betamethasone in group A, and ropivacaine, betamethasone, and saline in group B) or saline (group C) were injected into the joint and tendon site, respectively. The length of hospital stay, postoperative tramadol injection volume, incidence of complications, degree of knee joint swelling and range of motion, visual analogue scale (VAS) score, International Knee Documentation Committee (IKDC) score, Lyshlom score, and Hospital for Special Surgery (HSS) score were recorded and compared between groups. The T2 * values in different cartilage regions were detected by MRI examination and the levels of TNF-α, IL-6, IL-1, MMP-3, MMP-13, and ACAN in synovial fluid were detected by ELISA method., Results: The patients in group A, B, and C were followed up (12.53±3.24), (13.14±2.87), and (12.82±3.32) months, respectively. All incisions healed by first intention. Compared with group C, group A and group B had shorter length of hospital stay, less tramadol injection volume, and lower incidence of complications, showing significant differences ( P <0.05); there was no significant difference between group A and group B ( P >0.05). The degree of knee swelling in group A was significantly less than that in group B and group C ( P <0.05), but there was no significant difference between group B and group C ( P >0.05). At 3, 6, 12, 24, and 48 hours after operation, VAS scores of group A and group B were significantly lower than those of group C ( P <0.05); at 72 hours after operation, there was no significant difference among the three groups ( P >0.05). At 3 days, 14 days, and 1 month after operation, the range of motion of knee joint in group A were significantly better than those in group C ( P <0.05), and there was no significant difference between the other groups ( P >0.05). At 1 month after operation, the IKDC score of group A and group B was significantly higher than that of group C ( P <0.05); there was no significant difference among the three groups at other time points ( P >0.05). There was no significant difference in Lyshlom score and HSS score among the three groups at each time point ( P >0.05). At 14 days after operation, the levels of IL-1 and IL-6 in the synovial fluid in groups A and B were significantly lower than those in group C ( P <0.05). There was no significant difference in the levels of TNF-α, MMP-3, MMP-13, and ACAN between groups A and B ( P >0.05). At 1 month after operation, there was no significant difference in the above indicators among the three groups ( P >0.05). At 3, 6, and 12 months after operation, there was no significant difference in the T2 * values of different cartilage regions among the three groups ( P >0.05)., Conclusion: Injecting MDC (ropivacaine, tranexamic acid, betamethasone) into the joint and tendon site during ACLR can achieve good early effectiveness without significant impact on cartilage.

Purpose:  To determine femoral construct fixation strength as bone plug length decreases in anterior cruciate ligament reconstruction (ACLR)., Methods:  Sixty fresh-frozen bone-patellar tendon-bone allografts were utilized and divided into 20-, 15-, and 10-mm length bone plug groups, subdivided further so that half utilized the patella side (P) for testing and half used the tibial side (T). Ten mm diameter recipient tunnels were created within the anatomic anterior cruciate ligament footprint of 60 cadaveric femurs. All bone plugs were 10 mm in diameter; grafts were fixed using a 7 × 23 mm metal interference screw. An Instron was used to determine the load to failure of each group. A one-way multivariate analysis of variance (MANOVA) was conducted to test the hypothesis that there would be one or more mean differences in fixation stability between 20- or 15-mm plug lengths (P or T) versus 10 mm T plug lengths when cross-compared, with no association between other P or T subgroups., Results:  The mean load to failure of the 20 mm plugs (20 P + T) was 457 ± 66N, 15 mm plugs (15 P + T) was 437 ± 74N, and 10 mm plugs (10 P + T) was 407 ± 107N. There was no significant difference between P + T groups: 20-versus 15-mm ( p  = 1.000), 15-versus 10-mm ( p  = 0.798), and 20-versus 10-mm ( p  = 0.200); P + T MANOVA ( p  = 0.291). Within groups, there was no significant difference between patella and tibial bone plug subgroups with a pullout force range between 469 ± 56N and 374 ± 116N and p -value ranging from p  = 1.000 for longer bone plugs to p  = 0.194 for shorter bone plugs; P versus T MANOVA ( p  = 0.113)., Conclusion:  In this human time zero cadaver model, there was no significant difference in construct failure between 20-,15-, and 10-mm bone plugs when fixed with an interference screw within the femoral tunnel, although fixation strength did trend down when from 20- to 15- to 10-mm bone plugs., Clinical Relevance:  There is a balance between optimal bone plug length on the femoral side for achieving adequate fixation as well as minimizing donor site morbidity and facilitating graft passage in ACLR. This study reveals utilizing shorter plugs with interference screw fixation is potentially acceptable on the femoral side if shorter plugs are harvested., Competing Interests: None declared., (Thieme.

Background: Surgical treatment helps to restore stability of the elbow in patients with posterolateral rotatory instability (PLRI). The anconeus muscle is one of the most important active stabilizers against PLRI. A minimally invasive anconeus-sparing approach for lateral ulnar collateral ligament (LUCL) reconstruction using a triceps tendon autograft has been previously described. The purpose of this study was to evaluate the outcome of this intervention and identify risk factors that influenced the clinical and patient-reported outcomes., Methods: Sixty-one patients with chronic PLRI and no previous elbow surgery who underwent surgical reconstruction of the LUCL using a triceps tendon autograft in a minimally invasive anconeus-sparing approach during 2012 and 2018 were evaluated. Outcome measures included a clinical examination and the Oxford Elbow Score (OES) and the Mayo Elbow Performance Score (MEPS) questionnaires. Subjective patient outcomes were evaluated with the visual analog scale (VAS) for pain and the Subjective Elbow Value (SEV). Integrity of the common extensor tendons and centering of the radial head were assessed preoperatively on standardized magnetic resonance images (MRIs)., Results: Fifty-two patients were available at final follow-up. The mean age of patients was 51 ± 12 years with a mean follow-up of 53 ± 14 months (range 20-76). Clinical examination after surgery (n = 41) showed no clinical signs of instability in 98% of the patients (P < .001) and a nonsignificant improvement in range of motion. OES, MEPS, and VAS scores averaged 40 ± 10 of 48 points, 92 ± 12 of 100 points, and 1 ± 2 points, respectively, all corresponding with good or excellent outcomes. The SEV was 88%, indicating very high satisfaction with the surgery. Only 1 patient had revision surgery due to pain, and there were no reported postoperative complications in this cohort. A radial head subluxation in the MRI correlated significantly with worse postoperative outcomes., Conclusions: The anconeus-sparing minimally invasive technique for posterolateral stabilization of the elbow using a triceps tendon autograft is an effective and safe treatment for chronic posterolateral instability of the elbow with substantial improvements in elbow function and pain relief with a very low rate of persistent clinical instability., (Copyright © 2024 Journal of Shoulder and Elbow Surgery Board of Trustees.

Background: The use of allografts and autografts has been met with mixed views on whether allografts are a suitable alternative to autografts., Question: We aimed to investigate if chemically sterilized allografts show similar rerupture rates to those reported in the literature for allografts and autografts in anterior (ACL) and posterior cruciate ligaments (PCL) and complex knee surgery., Materials and Methods: Retrospective data on knee reconstructions performed between 2011 and 2015 with tendon/ligamnet allografts sterilized with peracetic acid were collected in the form of a questionnaire. The inclusion criteria of 2 years for each patient were met by 38 patients, representing 22 ACL reconstructions, 5 PCL reconstructions, 3 OTHER surgeries, including the Larson technique and medial patellofemoral ligament (MPFL) reconstruction and 8 COMPLEX surgeries. The main endpoints were rerupture and complication rate. Secondary endpoints included stability of the knee (Lachman test, Pivot shift test) and the range of motion., Results: The rerupture rate was 7.9% (3 grafts). Reruptures only occurred in the ACL group. No reruptures were observed in the PCL, OTHER and COMPLEX surgery groups. Stability improved significantly after surgery and the range of motion returned to values similar to that of healthy knees., Conclusions: Tendon allografts sterilized with peracetic acid show promising low rerupture rates and good clinical scores and the results are comparable to the literature on autografts and other allografts., (© 2024.
