Risk Factors for Recurrence of Shoulder Instability After Arthroscopic Bankart Repair

The higher failure rates reported with arthroscopic stabilization of traumatic, recurrent anterior shoulder instability compared with open stabilization remain a concern. The purpose of this study was to evaluate the outcomes of arthroscopic Bankart repairs with the use of suture anchors and to identify risk factors related to postoperative recurrence of shoulder instability.

Ninety-one consecutive patients underwent arthroscopic stabilization for recurrent anterior traumatic shoulder instability. The mean age (and standard deviation) at the time of surgery was 26.4 +/- 5.4 years. Seventy-one patients were male. Seventy-nine patients were involved in sports (forty, in high-risk sports). Capsulolabral reattachment and capsule retensioning was performed with use of absorbable suture anchors (mean, 4.3 anchors; range, two to seven anchors). All patients were prospectively followed, and, at the time of the last review, the patients were examined and assessed functionally by independent observers.
