Arthroscopic revision of Bankart repair.

The success of revision surgery for failed Bankart repair is not well known. This purpose of this study was to report the success rates achieved using arthroscopic techniques to revise failed Bankart repairs. Twelve arthroscopic revision Bankart repairs were performed on patients with recurrent unidirectional shoulder instability after open or arthroscopic Bankart repair. Follow-up was available on 11 of the 12 patients at a mean of 34.4 months (range, 25-56 months). The surgical findings, possible modes of failure, shoulder scores (Rowe score, University of California Los Angeles [UCLA], Simple Shoulder Test), and clinical outcome were evaluated. Various modes of failure were recognized during revision arthroscopic Bankart repairs. Good-to-excellent results were obtained in 8 patients (73%) undergoing revision stabilization according to Rowe and UCLA scoring. A subluxation or dislocation event occurred in 3 (27%) of the 11 patients at a mean of 8.7 months (range, 6-12 months) postoperatively. Arthroscopic revision Bankart repairs are technically challenging procedures but can be used to achieve stable, pain-free, functional shoulders with return to prior sport. Owing to limited follow-up and the small number of patients in this study, we were unable to conclude any pattern of failure or selection criteria for this procedure.
