Summary:Arthroscopy-assistcd rotator cuff repair utilizes advanced arthroscopic techniques and consists of arthroscopic subacromial decompression and rotator cuff mobilization, with rotator cuff repair being performed through a small deltoid- splitting incision that does not require release of the deltoid origin from the acromion. It is well tolerated by most patients and can be performed as an outpatient procedure. This approach to rotator cuff repair allows for easier and earlier rehabilitation because the deltoid does not have to be protected. Two-year followup results are similar to outcomes reported for open techniques.
