Arthroscopic salvage of failed arthroscopic Bankart repair: a prospective study with a minimum follow-up of 4 years

BACKGROUND: Data on arthroscopic salvage of failed arthroscopic Bankart repair are lacking. PURPOSE: To prospectively evaluate the surgical outcome of arthroscopic salvage of failed arthroscopic Bankart repair. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Operations were performed on 10 patients (8 male and 2 female; mean age at revision, 25.6 years; range, 18-41 years). The mean interval from the time of the revision surgery to the final follow-up was 68 months (range, 46-83 months). Objective testing included preoperative and postoperative range of motion. Outcome measures included the rating system of the University of California at Los Angeles. The surgical procedure was performed in a consistent manner: capsular plications, suture anchor repair of the displaced labrum, and, when indicated, rotator interval closure. RESULTS: The University of California at Los Angeles rating system showed a statistically significant improvement from a preoperative mean rating of 11.7 (range, 6-14) to a mean of 31.7 (range, 29-35) postoperatively (P < .05). All patients had a full and equal postoperative range of motion compared with the preoperative range of motion. One patient experienced recurrent dislocations after the salvage procedure. None of the other 9 patients experienced a recurrent dislocation, with all returning to their previous sports levels. CONCLUSION: Arthroscopic Bankart revision surgery is a reliable procedure with respect to recurrence rate, range of motion, and shoulder function in carefully selected patients.
