Title: Arthroscopic Decompression Versus Diagnostic Arthroscopy Without Subacromial Decompression Versus Supervised Exercise Therapy in Treatment of Subacromial Impingement Syndrome. A Blinded Randomized Controlled Trail.
Brief Summary: pShoulder impingement syndrome is common and number of operations done per year is growing. The aim of this study is to compare the value of arthroscopic subacromial decompression (acromioplasty group) vs. diagnostic arthroscopy (control group) vs. supervised exercise therapy (conservative group) on subjects with chronic subacromial impingement syndrome. The results of treatment are measured at 3 months, 6 months, 12 months, 24 months, 5 years and 10 years. Primary outcome measures are pain at rest and activity (VASs) and secondary outcomes are functional assessment of the shoulder with Constant score and Simple Shoulder test (SST), global assessment of change , quality of life assessment (SF-36 and 15D) and costs. At 10 year follow-up, MRI imaging is obtained and the findings compared to baseline imaging.
