Surgical intervention in EDS is challenging due to potential complications such as poor wound healing and tissue fragility.

Patients with vascular EDS were excluded. Demographic and surgical data, including graft type, cause of injury, concomitant procedures such as meniscus repair and anatomical measurements (posterior tibial slope, intercondylar notch width, lateral femoral condyle morphology, tibiofemoral rotation and tibial tubercle- trochlear groove distance), were collected. Survival analysis was performed using Kaplan-Meier curves, with endpoints defined as ACLR failure or conversion to total knee arthroplasty (TKA).

They underwent a surgical intervention involving arthroscopy-assisted subscapularis-complex release and conjoint muscle transfer onto the infraspinatus footprint on the humeral head. The evaluation of shoulder function was conducted using the Mallet score system, and the range of motion was measured at preoperative and six month postoperative intervals. Statistical analyses were performed to determine the significance of the outcomes.</p><p><strong>Results: </strong>The average age of participants was 4.83 ± 2.1 years. Preoperatively, the mean Mallet score was 14.08 ± 1.4, which improved to 23.83 ± 1.2 postoperatively. The average gain in shoulder abduction was 66.4 ± 5.6°, and external rotation improved by 85.4 ± 16.6° at 18 months final follow-up. All patients exhibited improvements in shoulder function, with a significant correlation (p value = 0.037) between Naraka grading, and clinical outcomes.</p><p><strong>Conclusion: </strong>The combined surgical approach of arthroscopic subscapularis-complex release with conjoint tendon transfer effectively enhances the shoulder function in the studied cohort. Further research and extended follow-up are needed to evaluate the long-term benefits.</p><p><strong>Level of evidence: </strong>Level IV (Therapeutic case series).</p>","PeriodicalId":14450,"journal":{"name":"International Orthopaedics","volume":" ","pages":"2529-2537"},"PeriodicalIF":2.6,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144794410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
