[Arthroscopic subacromial decompression].
The aim of this prospective study was to evaluate the results of arthroscopic subacromial decompression (ASAD) in the treatment of impingement syndrome in patients without full thickness rotator cuff tears. Sixty patients (64 operative procedures) underwent ASAD during the study period; 37 men and 23 women, average age 46 years (range 28-63), average duration of symptoms 37 months (range 8-132). Patients with calcifying tendintis were not included. Evaluation preoperatively and one year postoperatively included: Constant score, clinical examination and radiological evaluation (supraspinatus outlet view). All follow-up examinations were done by an independent observer. Fifty-six patients (60 procedures) were available for follow-up. The average length of follow-up was 13 months (range 10-23). Forty-six patients (77%) achieved a good or excellent result according to Constant score criteria. Preoperatively twenty-four patients had applied for worker's compensation benefits (WCB). Only half of the patients in the WCB group achieved a satisfactory result, whereas 94% of the non-WCB patients had a good or an excellent result. Arthroscopic subacromial decompression is an effective procedure for the majority of patients with stage II impingement syndrome. In this study WCB claims were associated with inferior results.
