Background Arthroscopic Bankart repair is a widely accepted treatment for anterior shoulder instability. The choice between knotted and knotless suture anchors has biomechanical implications, though clinical outcomes remain unclear. Purpose This study compares clinical outcomes of knotted versus knotless suture anchors in arthroscopic Bankart repair. Methods A retrospective single-centered review of 22 patients undergoing arthroscopic Bankart repair (July 2022 to December 2024) was conducted. Patients were categorized into two equal groups based on knotted or knotless anchor types. The Constant-Murley Shoulder (CMS) score was used as the primary outcome. Secondary outcomes included recurrence and surgical complications. Results There was no significant difference in postoperative CMS between knotted and knotless groups ( p = 0.058). Both groups showed significant improvements from baseline; no recurrences occurred. One case of wound infection was observed in the knotted group. Conclusion Knotted and knotless suture anchors showed comparable clinical outcomes in arthroscopic Bankart repair. Biomechanical advantages of knotless anchors may not necessarily translate into better clinical outcomes. Surgeons may choose anchor type based on preference and case-specific considerations.
