A rotator cuff is a group of four muscles and tendons that help in stabilizing the shoulder joint and support the movement of the shoulder. In cases where one or more of the rotator cuff tendons are torn, the tendons no longer fully attach to the head of the humerus. The tear can either be a partial tear or full thickness tear. Surgical intervention is required to repair a torn rotator cuff. It involves re-attaching the tendon to the head of humerus. The three most common techniques used to repair the rotator cuff include traditional open repair, arthroscopic repair, and mini-open repair.
