2026 AOSSM Annual Meeting: Functional Outcomes From Arthroscopic Treatment of Recurrent Anterior Shoulder Instability

119 patients with recurrent anterior shoulder instability and subcritical glenoid bone loss were randomized to receive arthroscopic anatomic glenoid reconstruction (AAGR) or arthroscopic Bankart repair. The outcomes of interest were redislocation and Western Ontario Shoulder Instability (WOSI) scores, achievement of the WOSI minimal clinically important difference (MCID), passive shoulder range of motion, and strength. Outcomes were assessed preoperatively and at six months, one year, and two years postoperatively. Overall, the results revealed that AAGR produced a lower two-year redislocation rate and a greater proportion of patients achieving clinically meaningful WOSI improvement than Bankart repair. Both groups improved in range of motion and strength over time, without significant between-group differences. These findings suggest that AAGR provides superior stability and patient-reported recovery without compromising shoulder function.
