The purpose of this study was to evaluate the minimum 2-year-follow-up result of arthroscopic Bankart repair using suture anchor (ASB) for traumatic anterior glenohumeral instability and made a comparison of the result between the with and without arthroscopic rotator interval closure (ASRIC). We retrospectively studied 105 shoulders of 103 patients. There were 71 male and 32 female patients. The average age at operation was 24.1 years old. 71 shoulders underwent ASB (group S), and 34 shoulders underwent ASB and ASRIC together (groupR). A comparison of the clinical results between with (group S) and without ASRIC (group R) was made. Postoperatively, 6 shoulders (8.5%) in group S and 3 shoulders (8.8%) in group R experienced recurrences. At the time of the final follow-up, the average loss of external rotation was 7.9° in group S and 11.4° in group R with the arm at the side, and 6.3° in group S and 7.8° in group R with the arm in 90° of abduction. The averaged Japanese Shoulder Society shoulder instability score (JSS-IS score) changed from 50.2 before surgery to 94.7 after surgery in group S, from 48.3 before surgery to 93.8 in group R. No significant differences were observed in the recurrence rate, shoulder ROM and JSS-SI score at the time of the final follow- up between group S and R. Rotator interval closure did not affect the result of arthroscopic Bankart repair.
