Arthroscopic acromioplasty: history, rationale, and technique

Subacromial impingement or supraspinatus syndrome has been known to exist in some form since the early 1900s. Several early studies have discussed subacromial impingement or supraspinatus syndrome. Arthroscopic acromioplasty has evolved as a useful surgical treatment. Pertinent physical examination and radiographic evaluation findings must be identified. In order for the surgery to be successful, it is important to understand the rationale for treatment of impingement syndrome and the technical aspects of arthroscopic acromioplasty.
