Clinical outcomes of revision arthroscopic Bankart repair for anterior shoulder instability: a systematic review of studies.

Background: The purpose of this study was to review the literature to ascertain the functional outcomes, recurrence rates, and subsequent revision rates following revision arthroscopic Bankart repair.

Methods: Two independent reviewers performed a literature search based on PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines using the Embase, MEDLINE, and Cochrane Library databases. Studies in which arthroscopic Bankart repair was performed as a revision procedure were included. The clinical outcomes extracted and analyzed were functional outcomes, return to play, and recurrent instability.

Results: Fourteen studies with 433 patients met the inclusion criteria. The majority of patients were male patients (63.7%); the average age was 26.1 years (range, 14-58 years), and the mean follow-up period was 37.6 months (range, 10-144 months). The mean Rowe score was 84.2, and 79.7% of patients had good to excellent outcomes. The rate of return to play was 78.5%, with 47.5% of patients returning to their preinjury level of play across 10 studies. The rate of recurrent instability was reported in 12 studies, with 328 shoulders demonstrating 86 instability events (26.2%). The rate of recurrent instability due to dislocation was reported in 7 studies (n = 176), with 19 events (10.8%), whereas the rate of subluxation was reported in 4 studies (n = 76), with 6 events (7.9%).

Conclusions: Revision arthroscopic Bankart repair for anterior shoulder instability was shown to result in a high rate of recurrent shoulder instability. There was a relatively poor rate of return to sport among athletes, and only about half of the patients were able to return at or above their preoperative level of ability.
