What is the Difference Between AC Resection & Rotator Cuff Surgery?
AC resection is a surgical technique used to repair damage to the acromioclavicular (AC) joint inside the shoulder. Rotator cuff surgery is used to repair damage to the four shoulder muscles and related tendons collectively known as the rotator cuff.

The AC Joint
-
According to the American Orthopaedic Society for Sports Medicine, the AC joint is located at the meeting of a section of the shoulder blade called the acromion and the clavicle (collar bone).
The Rotator Cuff
-
According to the American Academy of Orthopaedic Surgeons, the rotator cuff covers the upper end of the humerus bone inside the shoulder. It is responsible for arm rotation and keeps the humerus secure in its socket.

Significance
-
Depending on individual circumstances, either AC resection or rotator cuff surgery may be necessary to restore proper function and movement of the shoulder.
AC Resection
-
In AC resection, a small segment of the clavicle is removed. Eventually, scar tissue replaces the missing bone, allowing for restored movement in the AC joint.
Rotator Cuff Surgery
-
In rotator cuff surgery, doctors remove damaged tissue and repair or reattach torn tendons or muscle.
