TI  - An evaluation of the responsiveness and discriminant validity of shoulder 
      questionnaires among patients receiving surgical correction of shoulder 
      instability.

AB  - 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 < 
      0.001) and 12-month (P = 0.011) evaluations. The ASES showed improvement at 6 
      months (P = 0.003), while the Constant score did not report significant 
      improvement until 12 months postoperatively (P = 0.001). 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.
