Subacromial impingement: is there correlation between symptoms, arthroscopic findings and outcomes?

Methods Fifty-five patients who underwent arthroscopic subacromial decompression were analyzed. Pre-operatively patients completed an assessment form consisting of visual analogue pain score, and shoulder satisfaction. The degree of clinical impingement was also recorded. At arthroscopy impingement was classified according to the Copeland-Levy classification. Post-operatively the shoulder assessment was repeated. Statistical analysis was carried to determine if the degree of impingement at arthroscopy correlated with pre-operative pain, satisfaction and clinical signs of impingement.
