Abstract
PURPOSE: To review the current literature available and evaluate the efficacy of arthroscopic repair of 270° and 360° labral tears, as well as the complication rates associated with such. In addition, we intend to investigate whether consistent clinical findings can be observed in these patients. METHODS: This review is registered in the PROSPERO database. The MEDLINE, Cochrane Library, Scopus, and EMBASE databases were queried, and additional searches were performed manually. Studies that reported outcomes after arthroscopic repair of a minimum of 270° of glenoid labrum were included. Technique articles, repairs of less than 270°, studies on atraumatic multidirectional instability, and studies that lacked observable outcomes were excluded. RESULTS: In total, 3031 studies/documents were identified from database and manual searching. Screening, removal of duplicates, and assessment for inclusion/exclusion criteria resulted in 6 level IV studies for review. History and physical examination, as well as advanced imaging findings, were variable across studies. All studies reported satisfactory outcomes at short- to mid-term follow-up, although there was heterogeneity in type of outcomes used. Return to sport ranged from 75% to 100%. Complication rates ranged from 10% to 30%. Notably, recurrence of instability and need for secondary surgery occurred in up to 15% of patients. CONCLUSIONS: The current literature suggests that although clinical and radiographic variability exist in the diagnosis of 270° and 360° glenoid labrum tears, successful outcomes and return to work/sport can be achieved with arthroscopic management at an average minimum follow-up of 1 year. These figures, however, are limited by heterogenous studies containing small numbers of patients. Complications occur in up to 30% of cases, including an instability recurrence rate of up to 15%. LEVEL OF EVIDENCE: Systematic review of Level IV evidence. Published by Elsevier Inc.
