The purpose of this study was to compare the clinical results of knotless and knot-tying suture anchors in arthroscopic Bankart repair of collision athletes. Thirty-eight athletes underwent arthroscopic Bankart repairs. The mean age of the patients at the time of surgery was 23 years. Bio-Knot-tying anchors were used in 18 patients, and Bio-Knotless suture anchors were used in 20 patients. Preoperative and postoperative evaluations were performed by Rowe scores. At the end of 40 months follow-up, both the knot-tying and the knotless suture anchor groups had similar postoperative results. There were no differences between Knot-Tying and Knotless repair about late disengagement and re-dislocation in this patient group. Knotless repair provided secure and low-profile repair without introducing complexities to the procedure of arthroscopic knot tying one.
