Abstract Achilles tendon reconstruction is an effective method of repairing Achilles tendon rupture defects. We introduce a new approach for Achilles tendon reconstruction using transversal calcaneal anchored autogenous semitendinosus tendon graft. The study aimed to evaluate the clinical role of this new Achilles tendon reconstruction. We retrospectively enrolled patients who underwent Achilles tendon reconstruction using transversal calcaneal anchored autogenous semitendinosus tendon graft for acute Achilles tendon rupture defects from 2016 to 2021. The clinical and radiological results were assessed at the preoperative and the final postoperative follow-up with Visual Analog Score (VAS) scores, American Orthopaedic Foot & Ankle Society (AOFAS) scores and Achilles tendon Total Rupture Scores (ATRS). Besides, at the last postoperative follow-up, the difference in ankle range of motion between the two side of the patients and the incidence of postoperative complications were recorded. Results revealed patients had significantly lower VAS and higher AOFAS and ATRS (P

BackgroundRobot-assisted technology has been widely used in orthopedic surgery, which can provide surgeons with higher accuracy and reduce radiation exposure. In spinal surgery, robots are often used to assist pedicle screw implantation, while there are relatively few studies on robot-assisted percutaneous kyphoplasty (PKP) under local anesthesia.MethodsA total of 96 patients with single-segment OVCF who met the inclusion criteria were included in this study. Fifty-six patients underwent robot-assisted PKP and forty patients underwent conventional PKP by the same group of surgeons. Collect the relevant parameters.ResultsThe puncture time and fluoroscopy times during puncture in the robot group were significantly less than those in the manual group (P

Abstract Background As a common disease in orthopedic clinics, popliteal cysts often coexist with intra-articular lesions. Compared with traditional open surgery, arthroscopic treatment of popliteal cysts is less traumatic, and intra-articular lesions can be treated. The ‘one-way valve’ mechanism of the popliteal cyst can be removed by expanding the communication between the articular cavity and the cyst to avoid cyst recurrence. In terms of arthroscopic techniques, the comparison of clinical effects between the double posteromedial portal (DPP) and single posteromedial portal (SPP) has rarely been studied. The purpose of this retrospective study was to compare the clinical effects of DPP and SPP. Methods A total of 46 consecutive patients with symptomatic popliteal cysts who underwent arthroscopic treatment were included in this study and followed for approximately 1 year. All patients were divided into two groups according to the arthroscopic portals (DPP group and SPP group). The cyst size, Lysholm score and Rauschening–Lindgren (R–L) grade were evaluated before the operation for all patients, and the intra-articular lesions, operative time and complications were recorded after operation. At the last follow-up, the Lysholm score and R–L grade were recorded, and magnetic resonance imaging was used to evaluate the outcome of the cyst. The clinical data of the two groups was statistically compared and analyzed. Results There were no significant differences in preoperative cyst size, Lysholm score or R–L grade between the two groups (P > 0.05). The operation time of the DPP group (67.52 ± 18.23 min) was longer than that of the SPP group (55.95 ± 16.40 min) (P = 0.030), but the recurrence rate of cysts in the DPP group (0%) was obviously lower than that in the SPP group (19.0%) (P = 0.046). There were no significant differences in the Lysholm score, R–L grade or complication rate between the two groups at the last follow-up (P > 0.05). Conclusion Arthroscopic treatment of popliteal cysts using double posteromedial portals was a safe and effective surgical method. Trial registration: ChiCTR, ChiCTR2200060115.

Aim: To assess the effectiveness of shear wave elastography (SWE) in diagnosing delaminated partial-thickness rotator cuff tears (DPT-RCT). Material and methods: A retrospective study was carried out on 137 patients with DPT-RCT. The study included complete clinical data, including the images of conventional ultrasound (US), SWE, Magnetic Resonance Imaging (MRI) and shoulder arthroscopic surgery. The features of US, SWE, and MRI were evaluated. The study analysed the Shear-Wave Velocity (SWV) among three types of DPT-RCT, and between the regions of tears, normal contralateral, and affected unilateral supraspinatus tendon. Furthermore, receiver operating characteristic (ROC) curves were evaluated. Results: The SWE detection rate was significantly higher (91.2%) compared to US (73.7%) and MRI (87.6%) for the overall diagnosis of DPT-RCT. Similarly, SWE yielded higher rates of detection for types 1 (89.5%) and 2 (92.3%) of DPT-RCT as compared to US (71.7%, 69.2%) and MRI (81.6%, 94.9%), respectively. However, there was no significant difference in the accuracy of diagnosing type 3 among the three methods. The SWV of the 137 supraspinatus tendon tears was 3.64±0.60 m/s, which was higher than that of the normal supraspinatus tendon (2.43±0.47 m/s, p<0.01) as well as the region of tears (1.61±0.54 m/s, p< 0.01). Nevertheless, there was no significant difference in SWV among the three types of DPT-RCT. The cutoff thresholds of SWV for identifying normal tendon from DPT-RCT and for identifying DPT-RCT from the region of tears were 2.96m/s and 2.39m/s, respectively. Conclusions: SWE with SWV can provide both quantitative and qualitative diagnostic information for DPT-RCT, which can be used as a crucial supplement imaging method. [ABSTRACT FROM AUTHOR]
