Arthroscopic anterior stabilization and posterior capsular plication for anterior glenohumeral instability: a report of 71 cases.

PURPOSE: Results after arthroscopic treatment of anterior glenohumeral instability continue to improve as advancements are made in instrumentation and techniques. We present 71 cases of anterior glenohumeral instability treated with arthroscopic anterior stabilization and posterior capsular plication.

TYPE OF STUDY: Case series.

METHODS: Arthroscopic anterior reconstruction and posterior inferior "pinch-tuck" capsular plication was performed in 71 shoulders (67 patients) with anterior glenohumeral instability. The average follow-up was 33.3 months (range, 20 to 24 months). Outcomes were assessed by completion of the Simple Shoulder Test (SST), Western Ontario Shoulder Instability (WOSI) Index, a Rowe score, and a subjective self-assessment shoulder instability form.

RESULTS: Postoperative dislocation occurred in 5 patients (7%). The average SST score was 11.2 (12 maximum) and the average WOSI Index was 85.6% (range, 30.6% to 100%). The average Rowe score was 85. Ninety-seven percent of patients reported they were able to return to their normal activity level, and 90% of patients reported that they were able to return to their previous level of athletics; 100% of patients reported that they were doing better than before surgery and were satisfied with their result; 100% of patients reported that they would undergo the procedure again.

CONCLUSIONS: Arthroscopic anterior stabilization using suture anchors, combined with posterior capsular suture plication, is a reliable treatment option for anterior glenohumeral instability.

LEVEL OF EVIDENCE: Level IV.
