Arthroscopic acromioplasty. The superiority of the posterior portal over the lateral portal.
The authors demonstrate that the posterior portal is superior to the lateral portal for performing an arthroscopic acromioplasty by using pre- and postoperative three-dimensional computed tomography scans to quantitate bone shape and volume. The posterior portal gives superior resection of volume of bone as well as superior contour of the bone, especially in removing the anterior acromial hook.
