Preoperative radiographs and magnetic resonance imaging scans were used to diagnose SLAP lesions, and arthroscopic views from the standard posterior portal were recorded. The traditional 10-type classification system for SLAP was used to classify these cases. A classification method for SLAP lesions associated with SGHL injury was introduced. This classification system was investigated by 4 observers to evaluate inter- and intraobserver reliability (kappa coefficient [κ]).</p><p><strong>Results: </strong>A total of 828 patients were included in this analysis; 61 patients (7.4%) could not be classified by the 10-type traditional classification, and 44 patients (5.3%) had SGHL lesions. A novel classification for 3 subtypes of SLAP with SGHL lesions was introduced. The mean κ value of the interobserver reliability for the classification approach was 0.796 (range, 0.678-0.854), indicating substantial agreement. The mean κ value for the intraobserver reliability was 0.883 (range, 0.779-0.964), indicating excellent agreement.</p><p><strong>Conclusion: </strong>This study demonstrated a novel classification system for SLAP lesions associated with SGHL injury by introducing a series of cases with characteristics that showed high inter- and intraobserver reliability. Such cases have not been reported before, and the classification correlates with surgical treatment. This classification may be used as a supplement to the traditional 10-type classification.</p>","PeriodicalId":19646,"journal":{"name":"Orthopaedic Journal of Sports Medicine","volume":"13 1","pages":"23259671241303464"},"PeriodicalIF":2.4,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11748399/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143009298","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}

At final follow-up, Lysholm scores and Tegner activity scale scores were collected.
