Arthroscopic Bankart Repair in Traumatic Anterior Shoulder Instability Using a Suture Anchor Technique

PURPOSE: The purpose of this study was to prospectively evaluate the surgical outcome of arthroscopic Bankart repair via suture anchors in patients with recurrent traumatic anterior shoulder instability with a minimum follow-up of 2 years. METHODS: We included 54 consecutive patients without an osseous Bankart lesion of greater than 25% of the glenoid circumference with a mean age of 25.3 years (range, 16 to 58 years) undergoing arthroscopic Bankart repair via suture anchors for traumatic anterior shoulder instability. The mean follow-up was 3.7 years (range, 2.3 to 5.2 years) at the final follow-up examination. Patients were evaluated prospectively according to the rating scales of Rowe, the American Shoulder and Elbow Surgeons, and Constant and Murley. One patient was lost to follow-up. RESULTS: After 3.7 years, 4 patients had recurrent instability: 3 had redislocated and 1 had recurrent subluxations. Thus the overall redislocation rate was 7.5%. Of the 4 redislocators, 3 had a traumatic onset of the redislocation. All shoulder scores (Rowe, American Shoulder and Elbow Surgeons, and Constant and Murley) revealed highly significant improvements postoperatively. At final follow-up, 85.7% of patients had returned to their preoperative sports level. CONCLUSIONS: Our results in this series demonstrate the efficacy of arthroscopic Bankart repair with suture anchors for the treatment of recurrent traumatic anterior shoulder instability with respect to recurrence rate, range of motion, and shoulder function during a mean follow-up of 3.7 years. LEVEL OF EVIDENCE: Level IV, therapeutic case series.
