Long-term outcomes of the arthroscopic Bankart repair: a systematic review of studies at 10-year follow-up

Background: The purpose of this study was to systematically review the evidence in the literature to ascertain the functional outcomes and recurrences rates, as well as subsequent revision rates, following arthroscopic Bankart repair at a minimum of 10 years' follow-up. Methods: Two independent reviewers performed a literature search based on Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, using the Embase, MEDLINE, and Cochrane Library databases. Studies were included if they were clinical studies on arthroscopic Bankart repair with a minimum of 10 years' follow-up. Statistical analysis was performed using SPSS software. Results: Our review found 9 studies including 822 shoulders meeting our inclusion criteria. The majority of patients were male patients (75.5%), the average age was 28.0 years (range, 15-73 years), and the mean follow-up period was 149.4 months. The most commonly used functional outcome score was the Rowe score, with a weighted mean of 87.0. Overall, 77.6% of athletes were able to return to sports postoperatively. The overall rate of recurrent instability was 31.2%, with 16.0% of patients having recurrent dislocations, and the overall revision rate was 17.0%. Evidence of instability arthropathy was found in 59.4% of patients, with 105% of patients having moderate to severe arthropathy. Discussion and conclusion: Arthroscopic Bankart repair for anterior shoulder instability has been shown to result in excellent long-term functional outcomes despite a relatively high rate of recurrent instability necessitating revision surgery. In addition, the high rate of instability arthropathy is a concern following arthroscopic Bankart repair in the long term. (C) 2019 Journal of Shoulder and Elbow Surgery Board of Trustees.
