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.
