Purpose: To compare the results of arthroscopic Bankart repair completed with knot-tying with results of the procedure performed with knotless suture anchors. Methods: We evaluated 82 patients who underwent arthroscopic Bankart repair. A total of 61 patients were treated with knot-tying suture anchors, and 21 patients were treated with knotless suture anchors during the same period. In all, 75 male and 7 female patients were studied. Mean patient age at the time of operation was 24 years (range, 16 to 42 years), and the mean follow-up period had a duration of 29 months (range, 24 to 41 months’ duration). Results: Shoulder scores improved in both groups (P < .05). Postoperative pain, patient satisfaction score, and redislocation rate were significantly different between the 2 groups, with the knot-tying suture anchor group showing better results (P = .007, P = .007, and P = .012, respectively). In the knot-tying suture anchor group, 4.9% (3 patients) experienced redislocation and 1 patient underwent revision surgery. The redislocation rate in the knotless suture anchor group was 23.8% (5 patients), and 4 patients underwent revision surgery. Conclusions: The knot-tying and knotless suture anchor groups showed improvement in postoperative shoulder scores after arthroscopic Bankart repair. However, results after the knotless technique was performed were unsatisfactory when compared with results in the standard suture anchor group, particularly in terms of redislocation rate. Level of Evidence: Level III, retrospective comparative therapeutic study.

Patient Demographics

We retrospectively evaluated patients who underwent arthroscopic Bankart repair with the use of knot-tying suture anchors or knotless suture anchors between August 2001 and September 2002. Medical records and intraoperative arthroscopic photographs of 123 shoulders in 117 patients were reviewed. Patients who had a classic Bankart lesion with good remaining labrum were included. Those with a bony Bankart lesion, an anterior labroligamentous periosteal sleeve avulsion (ALPSA)-like lesion, humeral

Discussion

The goal of the Bankart repair is to restore the attachment of the labral/capsular ligaments to the anterior and inferior glenoid rim. Proper repair results in a painless, nondislocating, nonsubluxating shoulder with adequate strength and nearly full range of motion. The Bankart procedure provides consistent and reliable results in eliminating anteroinferior instability and 93% to 97% good to excellent results.11, 12, 13 Arthroscopic repair with the use of suture anchors has the potential to

Conclusions

The knot-tying and knotless suture anchor groups showed improvement in postoperative shoulder scores after arthroscopic Bankart repair. However, results after the knotless technique was used were unsatisfactory in comparison with outcomes in the standard suture anchor group, particularly in terms of redislocation rate.
