Collegiate athletes face rigorous physical, academic, and emotional demands. While significant attention has been paid to injury prevention among young athletes in the past two decades, orthopedic injury rates remain high among collegiate athletes, and a significant number will undergo surgical management for injuries each year. In this narrative review, we describe techniques for perioperative management of pain and stress after surgery in collegiate athletes. In particular, we outline pharmacologic and non-pharmacologic management of surgical pain, with a goal of minimizing opiate consumption. We emphasize a multi-disciplinary approach to optimizing post-operative recovery in collegiate athletes help minimize reliance on opiate pain medication. Additionally, we recommend that institutional resources should be harnessed to support athletes in their well-being, from a nutritional, psychological and sleep standpoint. Critical to success in perioperative pain management is the communication among the athletic medicine team members and with the athlete and family to address pain and stress management and encourage timely, safe return to play.

To compare complications, unplanned reoperations, and costs between single-stage and 2-stage treatment of multi-ligament knee injuries.The MarketScan database was queried (2007-2016), identifying patients undergoing surgery for a multi-ligament knee injury. The single-stage cohort was defined as having at least 2 Current Procedural Terminology codes for ligament reconstruction at the index procedure without a Current Procedural Terminology code for ligament reconstruction appearing in the database for the following 12 months. The 2-stage cohort was defined as undergoing multiple ligament reconstruction procedures within a 12-month period with subsequent ligament procedure codes that differed from the index ligament reconstruction codes. Propensity score matching was performed using a greedy nearest-neighbor algorithm to match specific injury patterns between the 2 cohorts. Baseline demographic characteristics, medical comorbidities, and the Charlson Comorbidity Index were recorded. Complications, unplanned reoperations, and total health care expenditures were recorded for up to 5-year follow-up. Two-sampleWe identified 1,150 patients who underwent surgery for multi-ligament knee injuries (1,080 with single-stage approach and 270 with 2-stage approach). No significant differences in baseline characteristics or medical comorbidities were found between the cohorts. After propensity score matching, the single-stage group had fewer complications at 30, 90, 180, and 365 days (Single-stage surgical treatment of multi-ligament knee injuries results in fewer complications and reoperations and lower total costs compared with 2-stage treatment, even after controlling for the number and combination of ligaments injured.Level III, retrospective cohort study.

Given the high volume of patient visits for foot and ankle complaints, developing a systematic approach to evaluation of foot and ankle pathology is important for orthopaedic providers. A thorough evaluation of weight-bearing radiographs is essential to differentiate acute and chronic injury from normal findings to dictate treatment. Radiographic changes and varying degrees of deformity can influence surgical considerations. The purpose of this article was to review and define radiographic measurements relevant to surgical decision making for common foot and ankle pathologies and treatment.

Background and purpose — In Malawi, both skeletal traction (ST) and intramedullary nailing (IMN) are used in the treatment of femoral shaft fractures, ST being the mainstay treatment. Previous studies have found that IMN has improved outcomes and is less expensive than ST. However, no cost-effectiveness analyses have yet compared IMN and ST in Malawi. We report the results of a cost-utility analysis (CUA) comparing treatment using either IMN or ST. Patients and methods — This was an economic evaluation study, where a CUA was done using a decision-tree model from the government healthcare payer and societal perspectives with an 1-year time horizon. We obtained EQ-5D-3L utility scores and probabilities from a prospective observational study assessing quality of life and function in 187 adult patients with femoral shaft fractures treated with either IMN or ST. The patients were followed up at 6 weeks, and 3, 6, and 12 months post-injury. Quality adjusted life years (QALYs) were calculated from utility scores using the area under the curve method. Direct treatment costs were obtained from a prospective micro costing study. Indirect costs included patient lost productivity, patient transportation, meals, and childcare costs associated with hospital stay and follow-up visits. Multiple sensitivity analyses assessed model uncertainty. Results — Total treatment costs were higher for ST ($1,349) compared with IMN ($1,122). QALYs were lower for ST than IMN, 0.71 (95% confidence interval [CI] 0.66–0.76) and 0.77 (CI 0.71–0.82) respectively. Based on lower cost and higher utility, IMN was the dominant strategy. IMN remained dominant in 94% of simulations. IMN would be less cost-effective than ST at a total procedure cost exceeding $880 from the payer’s perspective, or $1,035 from the societal perspective. Interpretation — IMN was cost saving and more effective than ST in the treatment of adult femoral shaft fractures in Malawi, and may be an efficient use of limited healthcare resources. publishedVersion

Context: A strict rehabilitation protocol is traditionally followed after microfracture, including weightbearing restrictions for 2 to 6 weeks. However, such restrictions pose significant disability, especially in a patient population that is younger and more active. Evidence Acquisition: An extensive literature review was performed through PubMed and Google Scholar of all studies through December 2018 related to microfracture, including biomechanical, basic science, and clinical studies. For inclusion, clinical studies had to report weightbearing status and outcomes with a minimum 12-month follow-up. Study Design: Clinical review. Level of Evidence: Level 3. Results: Review of biomechanical and biology studies suggest new forming repair tissue is protected from shear forces of knee joint loading by the cartilaginous margins of the defect. This margin acts as a shoulder to maintain axial height and allow for tissue remodeling up to at least 12 months after surgery, well beyond current weight bearing restriction trends. A retrospective case-control study showed that weightbearing status postoperatively had no effect on clinical outcomes in patients who underwent microfracture for small chondral (2) defects. In fact, 1 survey showed that many orthopaedic surgeons currently do not restrict weightbearing after microfracture. Conclusion: This clinical literature review suggests that weightbearing restrictions may not be required after microfracture for isolated tibiofemoral chondral lesions of the knee. Strength of Recommendation Taxonomy: C.

Proximal hamstring injuries are common, and open surgical repair with suture anchors has been the gold standard when surgical intervention is warranted. Endoscopic techniques offer the opportunity of surgical repair with smaller incisions to limit complications and expedite rehabilitation. The purpose of this technique guide is to describe a modified endoscopic technique that allows a safe and anatomic repair of proximal hamstring injuries. The patient is positioned prone with the feet at the head of the bed, table in reverse Trendelenburg, and knees flexed to 90°. Four portals are used, 3 in horizontal alignment within the gluteal fold and 1 directly superior to the ischial tuberosity. The sciatic nerve is identified, dissected, and mobilized away from the operative field. Retraction sutures help retract the gluteus maximus and further protect the sciatic nerve. Dissection is within the interval between the conjoint and semimembranosus tendons. The tendons are freed and mobilized, the ischial tuberosity is decorticated, and an anatomic repair is performed via 4 suture anchors, 2 at each tendon footprint. Advancements in arthroscopy have permitted adequate visualization and exposure of the hamstring footprint, thus allowing for an anatomic repair with increased protection of the sciatic nerve and decreased resources and cost.

Background: Psychological distress after orthopaedic surgery can lead to worse outcomes, including higher levels of disability and pain and lower quality of life. The 10-item Optimal Screening for Prediction for Referral and Outcome–Yellow Flag (OSPRO-YF) survey screens for multiple psychological constructs relevant to recovery from orthopaedic injury and may be useful to preoperatively identify patients who may require further psychological assessment and possible intervention after surgery. Purpose/Hypothesis: To determine the association between the OSPRO-YF and physiological patient-reported outcomes (PROs). It was hypothesized that higher OSPRO-YF scores (indicating worse psychological distress) would be associated with worse PRO scores at time of return to sport. Study Design: Case series; Level of evidence, 4. Methods: This study evaluated 107 patients at a single, academic health center who were assessed at a sports orthopaedics clinic and ultimately treated surgically for injuries to the knee, shoulder, foot, or ankle. Preoperatively, patients completed the OSPRO-YF survey as well as the following PRO measures: Patient-Reported Outcomes Measurement Information System (PROMIS), Single Assessment Numeric Evaluation, numeric rating scale for pain; American Shoulder and Elbow Surgeons standardized shoulder assessment form for patients with shoulder injuries, the International Knee Documentation Committee score (for patients with knee injuries), and the Foot and Ankle Ability Measure (FAAM; for patients with foot or ankle injuries). At the time of anticipated full recovery and/or return to sport, patients again completed the same PRO surveys. Multivariable regression was used to evaluate the association between total OSPRO-YF score at baseline and PRO scores at the time of functional recovery. Results: The baseline OSPRO-YF score predicted postoperative PROMIS Physical Function and FAAM Sports scores only. A 1-unit increase in the OSPRO-YF was associated with a 0.55-point reduction in PROMIS Physical Function (95% CI, –1.05 to –0.04; P = .033) indicating worse outcomes. Among patients who underwent ankle surgery, a 1-unit increase in OSPRO-YF was associated with a 6.45-point reduction in FAAM Sports (95% CI, –12.0 to –0.87; P = .023). Conclusion: The study findings demonstrated that the OSPRO-YF survey predicts certain long-term PRO scores at the time of expected return to sport, independent of baseline scores.

Background: No consensus exists regarding the superiority of operative versus nonoperative management for Achilles tendon ruptures, as multiple randomized controlled trials conducted since the advent of early mobilization protocols have found outcomes for these 2 interventions to be more similar than were previously held. Purpose: To use a large national database to (1) compare reoperation and complication rates between operative and nonoperative treatment of acute Achilles tendon ruptures and (2) evaluate trends in treatment and cost over time. Study Design: Cohort study; Level of evidence, 3. Methods: The MarketScan Commercial Claims and Encounters database was used to identify an unmatched cohort of 31,515 patients who sustained primary Achilles tendon ruptures between 2007 and 2015. Patients were stratified into operative and nonoperative treatment groups, and a propensity score—a matching algorithm—was used to establish a matched cohort of 17,996 patients (n = 8993 per treatment group). Reoperation rates, complications, and aggregate treatment costs were compared between groups with an alpha level of .05. A number needed to harm (NNH) was calculated from the absolute risk difference in complications between cohorts. Results: The operative cohort experienced a significantly larger total number of complications within 30 days of injury (1026 vs 917; P = .0088). The absolute increase in cumulative risk was 1.2% with operative treatment, which resulted in an NNH of 83. Neither 1-year (1.1% [operative] vs 1.3% [nonoperative]; P = .1201) nor 2-year reoperation rates (1.9% [operative] vs 2% [nonoperative]; P = .2810) were significantly different. Operative care was more expensive than nonoperative care at 9 months and 2 years after injury; however, there was no difference in cost between treatments at 5 years. Before matching, the rate of surgical repair for Achilles tendon rupture remained stable, from 69.7% to 71.7% between 2007 and 2015, indicating little change in practice in the United States. Conclusion: Results indicated no differences in reoperation rates between operative and nonoperative management of Achilles tendon ruptures. Operative management was associated with an increased risk of complications and higher initial costs, which dissipated over time. Between 2007 and 2015 the proportion of Achilles tendon ruptures managed operatively remained similar despite increasing evidence that nonoperative management of Achilles tendon rupture may provide equivalent outcomes.

BackgroundAnterior cruciate ligament (ACL) and meniscus tears are common knee injuries. Despite the high rate of post-traumatic osteoarthritis (PTOA) following these injuries, the contributing factors remain unclear. In this study, we characterized the immune cell profiles of normal and injured joints at the time of ACL and meniscal surgeries.MethodsTwenty-nine patients (14 meniscus-injured and 15 ACL-injured) undergoing ACL and/or meniscus surgery but with a normal contralateral knee were recruited. During surgery, synovial fluid was aspirated from both normal and injured knees. Synovial fluid cells were pelleted, washed, and stained with an antibody cocktail consisting of fluorescent antibodies for cell surface proteins. Analysis of immune cells in the synovial fluid was performed by polychromatic flow cytometry. A broad spectrum immune cell panel was used in the first 10 subjects. Based on these results, a T cell-specific panel was used in the subsequent 19 subjects.ResultsUsing the broad spectrum immune cell panel, we detected significantly more total viable cells and CD3 T cells in the injured compared to the paired normal knees. In addition, there were significantly more injured knees with T cells above a 500-cell threshold. Within the injured knees, CD4 and CD8 T cells were able to be differentiated into subsets. The frequency of total CD4 T cells was significantly different among injury types, but no statistical differences were detected among CD4 and CD8 T cell subsets by injury type.ConclusionsOur findings provide foundational data showing that ACL and meniscus injuries induce an immune cell-rich microenvironment that consists primarily of T cells with multiple T helper phenotypes. Future studies investigating the relationship between immune cells and joint degeneration may provide an enhanced understanding of the pathophysiology of PTOA following joint injury.

The athlete with shoulder instability poses a unique challenge to the sports medicine team. Clinical studies support surgical intervention followed by a phased approach to rehabilitation. In the latter phases, it is important to tailor this program to the individual’s specific athletic needs, which requires ongoing qualitative assessment and objective measurement. Passing a return-to-sport testing battery has been shown to decrease the risk of recurrent instability. What is lacking in the literature is a consensus for how to best measure shoulder performance when the required athletic demands are widely varied by hand dominance, sport played, and playing position. Multiple upper-extremity tests have been described in the literature, but there is no consensus on which tests should be used to direct rehabilitation and to safely return the athlete to unrestricted athletic exposure. Using available evidence, we suggest a framework for return-to-play testing that integrates traditional rehabilitation phases with performance testing and graduated sports exposure. Level of Evidence: Level V, expert opinion.

Background: The adoption of telehealth visits for physical therapy (PT) has accelerated because of the COVID-19 pandemic. Patient reception of virtual PT at the outbreak of the pandemic was positive, but it is unclear how telehealth visits compare to in-person visits in the postpandemic era. Purpose: To evaluate utilization trends and patient satisfaction with virtual PT compared with in-person PT during and after the COVID-19 pandemic. Study Design: Cross-sectional study; Level of evidence, 3. Methods: We identified 59,461 in-person and 2016 telehealth visits at a single physical rehabilitation center between March 2020 and December 2021. Patient socioeconomic and demographic variables, including insurance status, were compared between telehealth users and in-person visitors. A total of 1012 patient satisfaction surveys were available and analyzed using the top-box method. Univariable statistics ( t test or Mann-Whitney U and chi-square tests) were used for group comparisons. Results: Overall, telehealth users when compared with in-person visitors were older (median age, 47 vs 42 years, respectively; P < .001), and a higher proportion was female (60.6% vs 54.8%; P < .001), was White (69.7% vs 66.6%; P = .023), spoke English as their primary language (99.2% vs 98.1%; P = .001), and had Medicare insurance (20.3% vs 16.1%; P < .001). Telehealth patients more often lived out-of-county (50.7% vs 45.8%; P < .001) and in small towns rather than in urban areas (1.0% vs 0.3%; P < .001). When we compared telehealth use before and after official reopening of the PT center in September 2020, telehealth users in the postpandemic era had an out-of-county rate of 58.7%, and 68.7% were female. Patient satisfaction survey results demonstrated that telehealth patients compared with in-person patients were less likely to recommend visits to others (75.0% vs 89.1%, respectively; P = .008) and had lower overall assessment of their visits (71.7% vs 88.6%; P = .001). Accordingly, there was a significant reduction in telehealth visits from 2020 to 2021 (from 6.9% to 0.9% of visits; P < .001). Conclusion: We noted a decline in telehealth PT use during the postpandemic era, consistent with reduced patient satisfaction when compared with in-person visits. Telehealth is a useful option for populations with limited time or access to care and may serve a role in a hybrid care model. Further studies on long-term outcomes after telehealth PT are warranted to evaluate its efficacy.

Background: Osteochondral lesions of the tibial plafond (OLTPs) remain less common than osteochondral lesions of the talus (OLTs), but recognition of the condition has increased. Purpose: To systematically evaluate the literature on lesion locations and treatment outcomes of OLTPs, whether in isolation or in combination with OLTs. Study Design: Systematic review; Level of evidence, 4. Methods: A search was performed using the PubMed, Embase, and CINAHL databases for studies on lesion locations or with imaging or treatment outcomes of OLTPs. Case reports and reports based on expert opinion were excluded. Lesion locations as well as outcome measure results were aggregated. The Methodological Index for Non-randomized Studies score was used to assess methodological quality when applicable. Results: Included in this review were 10 articles, all published in 2000 or later. Most studies were evidence level 4, and the mean Methodological Index for Non-randomized Studies score was 8.6 (range, 8-10). Overall, 174 confirmed OLTP cases were identified, and the mean patient age was 38.8 years. Of the 157 lesions with confirmed locations, the most common was central-medial (32/157; 20.4%). Of 6 studies on treatment outcomes, all but 1 evaluated bone marrow stimulation techniques. Microfracture of small lesions (2) was the most common treatment utilized. Imaging and functional outcomes appeared favorable after treatment. The data did not support differences in outcomes between isolated OLTPs and OLTPs with coexisting OLTs. Conclusion: Osteochondral lesions of the distal tibia most commonly occurred at the central-medial tibial plafond. Microfracture of small lesions was the most common treatment utilized, and clinical and magnetic resonance imaging results were favorable, although data were heterogeneous. Areas for future research include the following: the effect of patient factors and additional pathologies on outcomes; larger or deeper lesion treatment; more direct comparisons of outcomes between kissing or coexisting lesions and isolated lesions; and head-to-head comparison of treatments, such as microfracture, bone marrow–derived cell transplantation, and osteochondral autografts/allografts.

Background: Revision shoulder stabilizations are becoming increasingly common. Returning to play after revision shoulder stabilizations is important to patients. Purpose: To evaluate the return-to-play rate after revision anterior shoulder stabilization using arthroscopic, open, coracoid transfer, or free bone block procedures. Study Design: Systematic review; Level of evidence, 4. Methods: All English-language studies published between 2000 and 2020 that reported on return to play after revision anterior shoulder stabilization were reviewed. Clinical outcomes that were evaluated included rate of overall return to play, level of return to play, and time to return to play. Study quality was evaluated using the Downs and Black quality assessment score. Results: Eighteen studies (1 level 2; 17 level 4; mean Downs and Black score, 10.1/31) on revision anterior shoulder stabilization reported on return to play and met inclusion criteria (7 arthroscopic, 5 open, 3 Latarjet, and 3 bony augmentation), with a total of 564 revision cases (mean age, 27.9 years; 84.1% male). The weighted mean length of follow-up was 52.5 months. The overall weighted rate of return to play was 80.1%. The weighted mean rate of return to play was 84.0% (n = 153) after arthroscopic revision, 91.5% (n = 153) after open revision, 88.1% (n = 149) after Latarjet, and 73.8% (n = 65) after bone augmentation. The weighted mean rate of return to same level of play was 69.7% for arthroscopic revision, 70.0% for open revision, 67.1% for Latarjet revision, and 61.8% after bone block revision. There were 5 studies that reported on time to return to play, with a weighted mean of 7.75 months (4 arthroscopic) and 5.2 months (1 Latarjet). The weighted mean rates of complication (for studies that provided it) were 3.3% after arthroscopic revision (n = 174), 3.5% after open revision (n = 110), 9.3% after Latarjet revision (n = 108), and 45.8% after bone block revision (n = 72). Conclusion: Revision using open stabilization demonstrated the highest return-to-play rate. Revision using Latarjet had the quickest time to return to play but had higher complication rates. When evaluated for return to same level of play, arthroscopic, open, and Latarjet had similar rates, and bone block had lower rates. The choice of an optimal revision shoulder stabilization technique, however, depends on patient goals. Higher-quality studies are needed to compare treatments regarding return to play after revision shoulder stabilization.

Background The purpose of this study was to describe trends in the incidence of open versus arthroscopic management of posterior shoulder instability (PSI) as well as the patients undergoing these procedures in the United States over time. Methods The PearlDiver Patient Records Database was utilized for this study. Cases of PSI and surgery were identified via the appropriate ICD-10-CM and CPT codes. Linear regression and two-sample Student's t-test were used to analyze incidence rates, procedure type, number of instability events, and patient age. Results A total of 5655 patients were identified as having PSI, undergoing a total of 686 capsulorraphies. The incidence of PSI treated surgically increased across the years of the study at a rate of 0.0293 per 100,000 person-years with an incidence in 2019–2020 greater than in 2016–2018 ( p = 0.0151). Patients undergoing arthroscopic capsulorrhaphy were on average younger than those undergoing open capsulorrhaphy ( p = 0.0021). Patients experienced a higher number of posterior instability events before open surgery compared to arthroscopic ( p = 0.0274). Discussion The incidence of surgical treatment of PSI in the United States is steadily rising, with greater than 90% of cases being treated arthroscopically. Those undergoing arthroscopic posterior stabilization are both younger and face fewer instability events prior to surgery.

Background: The COVID-19 pandemic has changed the practice of orthopaedic sports medicine. The threat of COVID-19 persists, and future restrictions to elective procedures are possible. It is important to understand how sports surgeons are prioritizing surgical cases during elective case restrictions and how telehealth is being incorporated into practice. Purpose: To understand how orthopaedic sports surgeons have triaged surgical sports cases and how telehealth is being utilized in response to COVID-19. Study Design: Cross-sectional study. Methods: A survey was presented to participants of the American Orthopaedic Society for Sports Medicine (AOSSM) webinar “Handling Sports and COVID-19” and distributed through email to all members of the AOSSM. The survey consisted of 25 questions with 3 sections: demographics, clinical practice, and telehealth. Descriptive statistics were performed. Results: Overall, 104 respondents participated. Respondents varied with respect to their location, type of clinical practice, and years in practice. The cases with the highest priority during triage included infections, fractures, and traumatic tendon ruptures (eg, quadriceps tendon). Before COVID-19, Conclusion: Telehealth has seen rapid adoption during the COVID-19 pandemic, and the majority of respondents plan to continue using it. It is being used more for established patients rather than new patient visits. For surgical cases, there was a clear triage priority of sports medicine cases, including infections, fractures, and traumatic tendon ruptures. Lower extremity cases had higher priority than upper extremity.

Background:Treatment of a first-time anterior shoulder dislocation (FTASD) is sensitive to patient preferences. The operative or nonoperative management debate provides an excellent opportunity to learn how surgeons apply patient preferences in treatment decisions.Purpose:To determine how patient preferences (repeat dislocation risk, recovery difficulties, fear of surgery, treatment costs) and surgeon factors influence a surgeon’s treatment plan for FTASD.Study Design:Cross-sectional study.Methods:Eight clinical vignettes of hypothetical patients with FTASD (including age, sex, and activity level) were presented to members of the Magellan Society. A second set of matched vignettes with patient preferences and clinical variables were also presented. The vignettes represented scenarios in which evidence does not favor one treatment over another. Respondents were asked how they would manage each hypothetical case. Respondents also estimated the risk of redislocation for the nonoperative cases for comparison with the published rates. Finally, respondents completed a Likert-scale questionnaire to determine their perceptions on factors influencing their decisions.Results:A total of 103 orthopaedic surgeons completed the survey; 48% practiced in an academic hospital; 79% were in practice for 10 years or longer; and 75% had completed a sports medicine fellowship. Patient preferences were the single most important factor influencing treatment recommendation, with activity type and age also important. Just 62% of the surgeon estimates of the risk of redislocation were consistent with the published rates. The inclusion of patient preferences to clinical variables changed treatment recommendations in 62.5% of our hypothetical cases. Respondents rated patient treatment preference as the leading factor in their treatment decision making.Conclusion:Patient preferences were important when deciding the appropriate treatment for FTASD. Respondents were inconsistent when applying evidence in their decision making and estimates of recurrent instability. Decision support tools that deliver patient preferences and personalized evidence-based outcome estimates improve the quality of decision making at the point of care.

Category: Sports; Basic Sciences/Biologics Introduction/Purpose: Syndesmosis injuries are common and frequently occur with deltoid injuries but optimal repair remains controversial. Prior biomechanical studies have demonstrated that 1 and 2 suture buttons are equivalent to screw fixation and that parallel or divergent suture buttons are equivalent to single suture button. Prior studies, however, created constructs with suture buttons within 1cm from each other (2-3cm from joint surface). Additionally, the role of deltoid injury and repair have not been evaluated in conjunction with syndesmosis injury and repair. The purpose of this study was to biomechanically compare a narrow vs spread 2-suture button construct with and without a deltoid repair. Methods: Four matched lower leg specimens (8 total specimens) aged mean 60.2 years (range 57-66 years; 6 females and 2 males; mean BMI 21.1) were tested. Ankle motion under cyclic loading was measured in multiple planes: first in the intact state, following simulated syndesmosis and deltoid injury, then following fixation with 1 of 2 randomly assigned constructs: 2 parallel suture buttons at 2 and 3cm from joint line (narrow); and 2 parallel suture buttons at 1 and 4cm from joint line (spread), and then finally following a deltoid repair with each construct. Each state was tested at a constant 750 N axial compressive force and 5N internal/external torque. Rotation position (degrees) and anterior-posterior displacement (mm) were collected throughout the testing to characterize relative spatial relationships of the tibiofibular articulation using 3D video capture technology. Results: Narrow and spread 2-suture button constructs improved rotation and translation compared to cut state (p0.05). There were no significant differences in rotation or translation between Narrow and Spread constructs (p>0.05). The addition of a deltoid repair did not improve rotation or translation compared to syndesmosis repair with either construct alone (p>0.05). Conclusion: The preliminary results of this study suggest that constructs with suture button placed close together or spread apart during fixation of combined syndesmosis and deltoid injury could improve rotation and translation equally. Additionally, in a combined syndesmosis and deltoid injury, the addition of a deltoid repair to a syndesmosis repair did not strengthen the construct. These findings suggest that repair of syndesmosis alone may be sufficient in combined syndesmosis and deltoid injuries. Additional matched samples will be tested to validate preliminary findings.

Background: The Short Musculoskeletal Function Assessment (SMFA) tool measures function and quality of life in patients with musculoskeletal conditions. Objective: This study aimed to translate and adapt culturally the SMFA into Chichewa, and assess its clinimetric properties. Methods: The translated Chichewa version was administered to 53 patients with musculoskeletal disorders. To assess repeatability, an additional 20 patients answered the questionnaire twice over a time interval of two weeks. Internal consistency, floor and ceiling effects, and repeatability were tested; construct validity was assessed with the World Health Organization Quality of Life Assessment tool (WHOQOL-BREF). Results: There was good internal consistency for both Dysfunction and Bothersome indices (Cronbach’s alpha 0.90) and good construct validity between both indices with the WHOQOL-BREF. Pearson’s correlation coefficient and intraclass correlation coefficient (ICC) for repeatability for the Dysfunction Index were 0.941 and 0.922 (95% CI: 0.772, 0.971) respectively, and 0.877 and 0.851 (95% CI: 0.629, 0.941) for the Bothersome Index respectively. Conclusion: The translated Chichewa SMFA is a valid tool for populations that speak the Chichewa language. publishedVersion

Background: Osteochondral lesion of the talus (OLT) may be caused by osteochondritis dissecans, osteochondral fractures, avascular necrosis, or focal arthritic changes. For certain focal cartilage defects, bone marrow stimulation (BMS) has been a widely used technique to restore a fibrocartilage substitute overlying the defect. There are various postoperative weightbearing protocols for this procedure, with no single gold standard method. Purpose: To retrospectively review the outcomes of patients undergoing ankle arthroscopy with concomitant BMS to determine outcomes based on postoperative weightbearing status. Study Design: Cohort study; Level of evidence, 3. Methods: We retrospectively reviewed the records of patients who underwent ankle arthroscopy with BMS for OLTs between 2015 and 2018. Patients were placed into 2 cohorts based on postoperative immobilization status: the nonweightbearing (NWB) group and the weightbearing-as-tolerated (WBAT) group. Patient characteristics obtained included age, sex, comorbidities, and etiology of talar pathology. Outcomes included the pain visual analog scale (VAS), range of motion (ROM), complications, time to first weightbearing, and the method and length of immobilization. Patients who were lost to follow-up before 30 days were excluded. The chi-square test was used to compare categorical variables between cohorts, and the t test was used for continuous variables. Results: A total of 69 patients met the inclusion criteria for this study, 18 in the WBAT group and 51 in the NWB group. The mean lesion size was 9.48 × 9.21 mm (range, 3-15 mm × 2-20 mm) for the NWB group and 9.36 × 9.72 mm (range, 5-14 mm × 6-20 mm) for the WBAT group ( P > .05). The VAS scores improved from 4.40 to 0.67 for the WBAT group and from 6.33 to 2.55 for the NWB group, with the difference in final values reaching statistical significance ( P = .0002). Postoperative ROM was not significantly different between the groups. There were 4 repeat operations within the NWB cohort. Conclusion: The surgical management of OLTs can be challenging, and the postoperative weightbearing protocol can be an extra obstacle for the patient to navigate. We found no difference in pain, ROM, or complications when allowing immediate, full WBAT.

Background: Modern techniques for graft choice, preparation, and fixation for anterior cruciate ligament (ACL) reconstruction demonstrate excellent longevity and return-to-play rates; however, up to 10% to 18% of cases continue to suffer reruptures, with even higher rates in specific subsets of patients. Indications: Normally, the posterior tibial slope is measured between 7° and 10°, with biomechanical and observational studies showing that posterior slope greater than 12° increases the risk of graft failure by 5× by allowing for increased anterior tibial translation, putting increased stress on the graft. The primary indication for a slope correction osteotomy with a revision ACL reconstruction is a patient with tibial slope greater than 12° who has failed prior ACL reconstruction. Technique Description: In our preferred technique, we illustrate a slope reducing anterior closing wedge proximal tibial osteotomy with concurrent revision ACL reconstruction rather than a staged ACL reconstruction. Results: The primary benefit of this technique is the ability to correct the tibial slope and reconstruct the ACL in one setting, which decreases recovery time, costs, and risks to the patients by eliminating an additional procedure. Discussion/Conclusion: In cases of ACL reconstruction failure, particularly in patients with multiple failures, an increased posterior tibial slope may be a contributing factor. Anterior closing wedge osteotomy has been shown to be an effective treatment, in patients with a native slope greater than 12°. A slope reducing anterior closing wedge proximal tibial osteotomy with concurrent revision ACL reconstruction rather than a staged ACL reconstruction has a wide array of benefits.

Background and purpose — Intramedullary nailing (IMN) is underutilized in low-income countries (LICs) where skeletal traction (ST) remains the standard of care for femoral shaft fractures. This prospective study compared patient-reported quality of life and functional status after femoral shaft fractures treated with IMN or ST in Malawi. Patients and methods — Adult patients with femoral shaft fractures managed by IMN or ST were enrolled prospectively from 6 hospitals. Quality of life and functional status were assessed using EQ-5D-3L, and the Short Musculoskeletal Function Assessment (SMFA) respectively. Patients were followed up at 6 weeks, 3, 6, and 12 months post-injury. Results — Of 248 patients enrolled (85 IMN, 163 ST), 187 (75%) completed 1-year follow-up (55 IMN, 132 ST). 1 of 55 IMN cases had nonunion compared with 40 of 132 ST cases that failed treatment and converted to IMN (p < 0.001). Quality of life and SMFA Functional Index Scores were better for IMN than ST at 6 weeks, 3 and 6 months, but not at 1 year. At 6 months, 24 of 51 patients in the ST group had returned to work, compared with 26 of 37 in the IMN group (p = 0.02). Interpretation — Treatment with IMN improved early quality of life and function and allowed patients to return to work earlier compared with treatment with ST. Approximately one-third of patients treated with ST failed treatment and were converted to IMN. publishedVersion

Background: The Cotton osteotomy, or dorsal-opening wedge osteotomy of the medial cuneiform (MC), is used to address medial column alignment to restore the static-triangle of support. There are many described techniques regarding the incision and osteotomy. Successful completion of the osteotomy requires knowledge of the anatomy, particularly the location of the medial dorsal cutaneous nerve (MDCN). This study describes the relationship between MDCN, tibialis anterior, extensor-hallucis-longus tendon, and ligamentous attachments to the MC. A technique to determine a safe location for the osteotomy is also described. Methods: Twelve fresh-frozen adult foot specimens were used for this study (7 male and 5 female). The MDCN and its branches were dissected and its relationship with the MC was documented. Osteotomy tilt angle and relationship to structures around the MC were measured. Results: MDCN traveled medially and distally over the dorsum of the MC, and a small branch to the MC was observed. The tilt angle was 80.1 ±1.4 degrees. There was no significant difference between the distance from the distal-articular surface to the midline of the cuneiform and to the interosseous ligament ( P = .69), or between the distance from the distal-articular surface to the second tarsometatarsal joint and to the origin of the Lisfranc ligament ( P = .12). Conclusions: The dorsal-medial-oblique incision effectively protected MDCN and the MC. We believe the osteotomy should be performed in the safe zone to maintain the stability of the opening wedge. Clinical relevance: The dorsal-medial-oblique incision could reduce the risk of injury to the MDCN and the tibialis-anterior tendon.

Background: There is little in vivo data that describe the relationships between patellar tendon orientation, patellar tendon strain, and anterior cruciate ligament (ACL) strain during dynamic activities. Quantifying how the quadriceps load the ACL via the patellar tendon is important for understanding ACL injury mechanisms. Hypothesis: We hypothesized that flexion angle, patellar tendon orientation, and patellar tendon strain influence ACL strain during a single-leg jump. Specifically, we hypothesized that patellar tendon and ACL strains would increase concurrently when the knee is positioned near extension during the jump. Study Design: Descriptive laboratory study. Methods: Models of the femur, tibia, ACL, patellar tendon, and quadriceps tendon attachment sites of 8 male participants were generated from magnetic resonance imaging (MRI). High-speed biplanar radiographs during a single-leg jump were obtained. The bone models were registered to the radiographs, thereby reproducing the in vivo positions of the bones, ligament, and tendon attachment sites. Flexion angle, patellar tendon orientation, patellar tendon strain, and ACL strain were measured from the registered models. ACL and patellar tendon strains were approximated by normalizing their length at each knee position to their length at the time of MRI. Two separate bivariate linear regression models were used to assess relationships between flexion angle and patellar tendon orientation and between ACL strain and patellar tendon strain. A multivariate linear regression model was used to assess whether flexion angle and patellar tendon strain were significant predictors of ACL strain during the inflight and landing portions of the jump. Results: Both flexion angle and patellar tendon strain were significant predictors ( P < .05) of ACL strain. These results indicate that elevated ACL and patellar tendon strains were observed concurrently when the knee was positioned near extension. Conclusion: Concurrent increases in patellar tendon and ACL strains indicate that the quadriceps load the ACL via the patellar tendon when the knee is positioned near extension. Clinical Relevance: Increased ACL strain when the knee is positioned near extension before landing may be due to quadriceps contraction. Thus, landing with unanticipated timing on an extended knee may increase vulnerability to ACL injury as a taut ligament is more likely to fail.

Background: Pectoralis major (PM) tendon tears are a relatively uncommon injury that typically occurs in a young, active population during weightlifting or recreational sports. Musculotendinous junction and chronic PM tears often require tendon reconstruction due to inadequate remnant tendon stump or inability to reduce the remnant tendon stump to humeral footprint. Indications: We favor operative repair or reconstruction of PM tears in all young and active patients medically appropriate for surgery as supported by the literature. We present a technique for PM tendon reconstruction with semitendinosus allograft. This technique is applicable to musculotendinous junction and chronic tears. Technique: A modified deltopectoral approach is used. The PM tear is identified at the musculotendinous junction and the retracted muscle belly is mobilized. The PM tendon is reconstructed with a semitendinosus allograft using a Pulvertaft weave technique. The humeral footprint is prepped and the reconstructed tendon is properly tensioned and reduced. Fixation is performed with fibertapes loaded on 3 unicortical buttons. Postoperatively, the patient follows a graduated rehabilitation protocol. Results: There is a paucity of literature regarding outcomes of PM tendon reconstructions for musculotendinous junction tears. One study reported outcomes on 6 patients who had musculotendinous junction tears and underwent semitendinosus allograft reconstruction with a technique similar to ours. They report good clinical outcomes with high patient satisfaction regarding cosmetic outcome, return of strength, and overall satisfaction postoperatively. Discussion: It is our experience that the described technique for reconstruction of the PM tendon with semitendinosus allograft provides a viable option with good clinical outcomes for patients with PM ruptures at the musculotendinous junction.

Category: Sports Introduction/Purpose: Osteochondral lesions of the talus (OLT) are common injuries, however management remains challenging. Lesion size remains a common determinant of treatment and microfracture remains common for smaller lesions. Microfracture provides access to mesenchymal stem cells within the subchondral bone. Dehydrated micronized allogenic cartilage (DMAC) (BioCartilage, Arthrex, Naples, FL) utilizes a single stage attempt to augment microfracture with a scaffold over the defect to improve hyaline cartilage restoration. DMAC requires hydration with plasma rich protein (PRP) or bone marrow aspirate concentrate (BMAC). Currently, there is limited literature on pain scores and return-to-activities and satisfactory return- to-sport following DMAC treatments. The purpose of this study is to report pain scores, percent and time return-to -activities, percent and time to satisfactory return-to-sport following microfracture + DMAC and isolated microfracture. Methods: We reviewed a series of 65 cases (37 female and 28 male; mean age 34.6 (SD 14.1); mean BMI 27.3 (SD 6.2)) between 2010 and 2019 in which surgical treatment for OLT consisted of microfracture + DMAC, or isolated microfracture. Surgical procedure was determined by treating surgeon. Demographic, visual analog scale (VAS) pain scores (0-10), return-to-activities, and satisfactory-return-to-sport were collected preoperatively and postoperatively at 3-months, 6-months, and 1 year. Return-to- activities was defined as any engagement in desired activities, whereas satisfactory-return-to-sport was determined by patient- report. T-tests were used to determine between group differences. Results: Sixty-five cases (DMAC 25; isolated-microfracture: 40) demonstrated mean pain score at 3-months for DMAC and isolated-microfracture of 0.8 and 2.0, respectively, (p=0.04). There were no significant differences in remaining pain scores. By 1- year, 100% of DMAC and 87.5% of isolated-microfracture returned-to-activities, p=0.09. Of those that returned-to-activities there was no difference in time-to-return-to-activities between groups 82.9 days vs 82.4 days. By 1-year, patients that return-to-sport demonstrated a patient-reported satisfactory-level-of-return of 52.0% in DMAC and 37.5% in isolated-microfracture. Of those that returned satisfactorily-to-sport, the time-to-satisfactory-return-to-sport was similar (mean 139.5 and 135.7 days, p=0.66). A subgroup analysis of microfracture + DMAC group determined that PRP (n=16) had less pain at 3 months than BMAC (n=9), mean 0.8 vs 2.0, respectively; p=0.03, with no other differences noted (p>0.05). Conclusion: The use of microfracture + DMAC may improve early post-operative pain scores and improve ability to return to a patient-reported satisfactory level of sport by 1-year. Isolated microfracture and DMAC augmentation had similar rates and times to return-to-activities, and pain levels after 6-months post-operatively. The use of PRP to supplement DMAC improved early post- operative pain scores compared to BMAC which may be related to donor-site morbidity. Otherwise PRP and BMAC supplementation of DMAC had similar subsequent pain scores, and rate and time to return to activities. Augmentation of microfracture with DMAC for OLTs may improve outcomes compared to microfracture alone.

Background:Primary shoulder stabilization is successful, but there continues to be a risk of recurrence after operative repair, particularly in the young athlete. It is important for surgeons to understand the outcomes after various revision stabilization techniques to best counsel patients and manage expectations.Purpose:To analyze recurrent instability and revision surgery rates in patients who underwent revision anterior glenohumeral stabilization procedures with either arthroscopic repair, open repair, coracoid transfer, free bone block, or capsular reconstruction.Study Design:Systematic review; Level of evidence, 4.Methods:We performed a systematic review of level 2 to 4 evidence studies using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Clinical studies of revision anterior glenohumeral stabilization (arthroscopic repair, open repair, coracoid transfer, free bone block, or capsular reconstruction) with a minimum 2-year follow-up were analyzed. The rate of recurrent instability, rate of revision surgery, patient-reported outcomes, and range of motion were extracted and reported. Study methodological quality was evaluated using the Downs and Black quality assessment score.Results:A total of 37 studies met inclusion criteria and were available for analysis: 20 studies evaluated arthroscopic repair, 8 evaluated open repair, 5 evaluated Latarjet procedure, 3 evaluated bone block, and 2 evaluated capsular reconstruction. There was 1 study included in both arthroscopic and Latarjet procedures, for a total of 1110 revision cases. There was 1 level 2 study, and the remainder were level 3 or 4 with poor Downs and Black scores. Participants analyzed were most commonly young (weighted mean age, 26.1 years) and male (78.4%). The weighted mean clinical follow-up after revision surgery was 47.8 months. The weighted mean rate of recurrent instability was 3.8% (n = 245) after the Latarjet procedure, 13.4% (n = 260) after open repair, 16.0% (n = 531) after arthroscopic repair, 20.8% (n = 72) after bone block, and 31.0% (n = 35) after capsular reconstruction. The weighted mean rate of additional revision surgery was 0.0% after bone block, 0.02% after the Latarjet procedure, 9.0% after arthroscopic repair, 9.3% after open repair, and 22.8% after capsular reconstruction. Patient-reported outcomes and objective measures of range of motion and strength improved with all revision techniques.Conclusion:The current review identifies a deficiency in the literature pertaining to consistent meaningful outcomes and the effect of bone loss after revision shoulder stabilization. Published studies demonstrate, however, that revision shoulder stabilization using arthroscopic, open, coracoid transfer, or bone block techniques yielded satisfactory objective and patient-reported outcomes. The Latarjet procedure exhibited the lowest recurrent instability rate. This study confirms that recurrent instability remains a common problem, despite revision shoulder stabilization. The quality of research in revision shoulder stabilization remains poor, and higher quality studies are needed to establish best practices for treatment of this complex problem.

Author(s): LaMartina, Joey A; Lau, Brian C; Miller, Liane; Salesky, Madeleine A; Feeley, Brian T; Ma, C Benjamin; Zhang, Alan L | Abstract: BackgroundThere is no standard method for the surgical treatment of acromioclavicular (AC) joint separations. Current techniques have associated complications, including need for device removal, coracoid fracture, and inadequate reduction.PurposeTo evaluate the clinical outcomes of an internal splint technique without graft augmentation or rigid fixation to treat acute Rockwood type IV and V AC joint injuries.Study designCase series; Level of evidence, 4.MethodsA retrospective analysis was performed of 26 patients who underwent a novel internal splint fixation technique between 2011 and 2016. Patients had type IV (n = 2) and type V (n = 24) acute AC separations. The mean time to surgery was 13.7 days (range, 1-28 days). The surgical technique included an open approach with coracoclavicular suture and tape fixation and AC suture fixation. Range of motion, strength, and radiographs were evaluated after surgery. Patient follow-up included the DASH (Disabilities of the Arm, Shoulder and Hand) questionnaire at a mean 3.3 years postoperatively (range, 6 months-8.6 years). DASH questionnaires were obtained for all patients via email. Patients were also surveyed on cosmetic appearance and willingness to undergo the operation again.ResultsAll patients regained full strength and range of motion following surgery. All postoperative radiographs demonstrated well-maintained reduction of the AC joint. The mean DASH score was 3.4 at final follow-up, and 23 of 26 respondents were satisfied with their postoperative shoulder appearance. There were no reoperations, and all patients stated that they would have the operation again given the same circumstances.ConclusionThe results of this study demonstrate a reliable new technique for acute fixation of type IV or V AC joint injuries via an internal splint construct. This technique enables reduction in the coronal and sagittal planes without the need for graft augmentation or a rigid implant, allowing healing of the coracoclavicular and AC ligaments.

BackgroundThe American Shoulder and Elbow Surgeons (ASES) score is composed of a patient-reported portion and a physician assessment. Although the patient-reported score is frequently used to assess postoperative outcomes after shoulder arthroplasty, no previous studies have used the physician-assessment component. This study evaluated the relationship of the ASES physician-assessment measurements with patient-reported shoulder and general health outcomes.MethodsA retrospective review of a prospectively collected multicenter database was used to analyze patients who underwent primary reverse total shoulder arthroplasty (RTSA) from 2012 to 2015 with a minimum 2-year follow-up. ASES physician-assessment and patient-reported components and 12-Item Short Form Health Survey (SF-12) general health questionnaires were obtained preoperatively and 2 years postoperatively. The relationship between ASES physician measurements with ASES patient-reported outcome (PRO) scores and SF-12 Physical and Mental domain scores was assessed with Pearson correlation coefficients.ResultsIncluded were 74 patients (32 men; mean age, 69.2 years; body mass index, 29.4 kg/m2). Preoperative physician measurements and PRO scores were not significantly correlated. Postoperatively, only the ASES physician-measured active (R = 0.54, P

Background: Convergence insufficiency (CI) is a common binocular vision deficit after a sport-related concussion (SRC). CI may result in visual discomfort and vision-mediated functional difficulties such as slowed reading and compromised attention, leading to impaired academic, work, and sport performance. Purpose: To test the reliability of repeated near point of convergence (NPC) measurements in a sample of athletes after an SRC; compare the symptoms and cognitive impairment of athletes with normal NPC to those with CI after an SRC; and explore the relationship among age, sex, learning disability, migraine history, and CI. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A total of 78 athletes (mean age, 14.31 ± 2.77 years) who were seen a mean 5.79 ± 5.63 days after an SRC were administered 3 trials of an NPC assessment, along with neurocognitive (Immediate Post-Concussion Assessment and Cognitive Testing [ImPACT]) and symptom assessments. Patients were divided into normal NPC (NPC ≤5 cm; n = 45) and CI (NPC >5 cm; n = 33) groups. Intraclass correlation coefficients (ICCs) and repeated-measures analyses of variance (ANOVAs) assessed the consistency of NPC across the 3 trials. The ANOVAs were employed to examine differences on neurocognitive composites and symptoms between the normal NPC and CI groups. Stepwise regressions (controlling for age and symptom scores on the Post-Concussion Symptom Scale [PCSS]) were conducted to evaluate the predictive utility of the NPC distance for neurocognitive impairment. Results: Groups did not differ on demographic or injury characteristics. NPC differed between trial 1 and trials 2 ( P = .02) and 3 ( P = .01) for the CI group but not the normal NPC group. Internal consistency was high across NPC measurements (ICC range, 0.95-0.98). Patients with CI performed worse on verbal memory ( P = .02), visual motor speed ( P = .02), and reaction time ( P = .001, η2 = .13) and had greater total symptom scores ( P = .02) after the injury. Results of hierarchical regression revealed that the NPC distance contributed significantly to the model for reaction time ( P < .001). Conclusion: CI was common (~42%) in athletes evaluated within 1 month after an SRC. Athletes with CI had worse neurocognitive impairment and higher symptom scores than did those with normal NPC. Clinicians should consider routinely screening for NPC as part of a comprehensive concussion evaluation to help inform treatment recommendations, academic accommodations, and referrals for vision therapy.

Background: The EQ-5D is a standardised instrument that measures health-related quality-of-life and explores cost-effectiveness of treatments. Malawi is a low-resource country that would benefit from assessment of quality-of-life among individuals living with chronic conditions. Chichewa is the official native language of Malawi. The Chichewa version of the EQ-5D-3L developed by EuroQoL group has not been validated with Chichewa speakers. The purpose of this study was to evaluate the clinimetric properties of the Chichewa EQ-5D-3L. Methods: Patients with orthopaedic conditions were recruited in the outpatient orthopaedic clinics and wards at Queen Elizabeth Central Hospital, Blantyre, Malawi. Fifty-three patients with various musculoskeletal problems were administered the Chichewa EQ-5D-3L and World Health Organization quality of life (WHO-QOL) questionnaires. To assess repeatability, a separate test–retest population of 20 patients were also selected from orthopaedic clinics and wards to fill out the questionnaire twice. Results: Convergence validity was determined, with each of the WHO-QOL domains and the EQ-5D descriptive index and visual analogue scale (VAS) having good to moderate correlation (r = 0.3–0.7). Internal consistency was measured for the descriptive index, and the Cronbach’s alpha was 0.7. The ceiling effect for the descriptive index and the VAS were 9.4% and 0%, respectively. No respondents reached floor effect for the descriptive index or the VAS. The test retest intraclass correlation coefficient reliability at 14 days was 0.984 for the VAS and 1 for the descriptive index, with all 20 respondents providing the same responses. Conclusions: The EuroQoL translated version of the Chichewa EQ-5D-3L was found to demonstrate adequate validity, internal consistency, floor/ ceiling effects, and reliability.
