BACKGROUND: Although arthroscopic glenoid labrum repair using the BioKnotless anchor is common, the benefits and efficacy have not been fully evaluated. HYPOTHESIS: BioKnotless suture anchor is a clinically and radiologically suitable material for arthroscopic labral repair. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Ninety-seven patients underwent arthroscopic glenoid labrum repair with BioKnotless anchor between July 2004 and December 2005. Thirty-seven patients had traumatic anterior instability and 60 patients had an isolated superior labrum, anterior-posterior (SLAP) lesion. The mean age at surgery was 36.0 years (range, 15-66); the average follow-up was 34.1 months (range, 24-54). Clinical outcomes were evaluated using range of motion and various functional evaluation scores including sports activity. Pain and patient satisfaction were measured using a visual analog scale (VAS). Computed tomography arthrography was conducted in 73 patients at least 1 year after surgery for radiologic evaluation. RESULTS: In patients with instability, the Western Ontario Shoulder Instability index and Rowe score improved from 53.2 to 85.9 and from 68.7 to 92.7, respectively. Return to normal recreation and sports were possible in 30 patients (81.1%); the mean satisfaction VAS was 9.2. There was 1 postoperative dislocation, and the apprehension test was positive in 1 case. Postoperative range of motion including external rotation was not different. In patients with a SLAP lesion, the American Shoulder and Elbow Surgeons score and Constant score improved from 67.3 to 96.0 and 79.1 to 96.8, respectively. Pain VAS decreased from 6.0 to 0.4, and the mean satisfaction VAS was 9.4. Return to normal recreation and sports were possible in 50 patients (83.3%). All labra were found to have firmly healed to bony glenoid rim without anchor-related osteolysis in postoperative CT arthrography. CONCLUSION: Clinically and radiologically, the BioKnotless anchor appears to be an acceptable alternative for arthroscopic labrum repair, and a suitable material allowing the avoidance of certain troublesome drawbacks of the conventional knot-tying suture anchor.
