Healing rates were 77.8% for DR and 83% for TOE-SB (odds ratio, 1.34 [95% CI, 0.53-3.38]; &lt;i&gt;P&lt;/i&gt; = .53). Multivariable regression analysis showed a positive correlation between nonhealing rates and the rotator cuff tear size in the sagittal plane (odds ratio, 1.97 (95% CI, 1.02-3.78); &lt;i&gt;P&lt;/i&gt; = .042).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;No difference was found between DR and TOE-SB rotator cuff repair in the Western Ontario Rotator Cuff index, the American Shoulder and Elbow Surgeons score, Constant strength subscore, or the healing rate. The Constant score at the 24-month follow-up favored DR repair but did not reach the minimal clinically","PeriodicalId":19646,"journal":{"name":"Orthopaedic Journal of Sports Medicine","volume":"13 1","pages":"23259671241307673"},"PeriodicalIF":2.4,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11783469/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143080527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
