Abstract

Health-related quality-of-life HRQL measures must detect clinically important changes over time and between different patient subgroups. Forty-three patients 32 M, 13 F; mean age  =  26.00  ±  8.19 years undergoing arthroscopic Bankart repair completed three validated shoulder questionnaires Western Ontario Shoulder Instability index WOSI, American Shoulder and Elbow Surgeons Standardized Shoulder Assessment form ASES, Constant score preoperatively, and at 6, 12, and 24 months postoperatively. Responsiveness and discriminant validity was assessed between those with a satisfactory outcome and those with 1 a major recurrence of instability, 2 a single episode of subluxation, 3 any postoperative episode of instability. Eight 20% patients reported recurrent instability. Compared to baseline, the WOSI detected improvement at the 6- 𝑃 < 0 . 0 0 1 and 12-month 𝑃 = 0 . 0 1 1 evaluations. The ASES showed improvement at 6 months 𝑃 = 0 . 0 0 3 , while the Constant score did not report significant improvement until 12 months postoperatively 𝑃 = 0 . 0 0 1 . Only the WOSI detected differential shoulder function related to shoulder instability. Those experiencing even a single episode of subluxation reported a 10% drop in their WOSI score, attaining the previously established minimal clinically important difference MCID. Those experiencing a frank dislocation or multiple episodes of subluxation reported a 20% decline. The WOSI allows better discrimination of the severity of postoperative instability symptoms following arthroscopic Bankart repair.
