Arthroscopic Acromioclavicular Joint Resection

Osteoarthritic findings of the acromioclavicular joint are commonly observed in adult population, especially with increased age. For symptomatic patients who resulted in failed conservative treatment, surgical treatment is needed. In addition to the classic open procedure for distal clavicle resection, the arthroscopic procedure has recently been popularized. There have been some studies describing the advantages of the arthroscopic procedure including faster return to activities and less complication rate than the open procedure. There are two approaches in arthroscopic procedure: the lateral subacromial (indirect) approach and the superior (direct) approach. The latter approach has advantage to preserve the inferior AC ligament and coracoacromial arch during the surgery. The amount of resection has been discussed in anatomical studies regarding the AC ligament insertion. The dynamic examination during arthroscopy is helpful in determining the optimal amount of resection.
