Editorial Commentary: #Fakeradiographicangle-Critical Shoulder Angle, Like Acromioplasty, May Not Be Critical

The critical shoulder angle (CSA) is found to have an association with rotator cuff tearing when the angle is greater than 35° to 38°. However, the CSA does not correlate with improved clinical patient outcome scores. Acromioplasty is no longer viewed as a critical part of rotator cuff surgery. Only meaningful comparative studies will allow us to conclude whether performing a lateral acromioplasty for a significant CSA will be an important step to prevent future retears after rotator cuff repair.
