The objective was to evaluate mid-term results after @entity5663 ( @entity5663 ) with special focus on the bias due to an application to social insurance for pension based on @entity717 . The study group consisted of 42 @entity1 (28 male, 14 female). @entity5663 was performed in 1993 or 1994 for impingement stage II. The mean age was 49.5 years. Thirty-nine @entity1 (93%) were evaluated by an independent observer for an average follow-up of 3.5 years (range 1.5-5). @entity1 satisfaction with the outcome was assessed by a visual analog scale graded from 0 (extremely dissatisfied) to 10 (extremely satisfied). The functional result was assessed using the Constant score. At follow-up the mean VAS value was 6.4 +/- 3.4. The Constant score improved from 49.6 +/- 18.5 to 84.8 +/- 14.3. The subgroup of @entity1 having applied to social insurance for pension had significantly worse results compared with the remaining @entity1 : VAS: 4.9 +/- 3.1 vs. 7.5 +/- 3.1; Constant-Score: 76.1 +/- 12.7 vs. 88.3 +/- 13.5. The fact that @entity1 try to get benefit from social insurance based on @entity717 significantly biased the outcome after @entity5663 .
