Learn about rotator cuff repair and the shoulder and elbow specialists who perform these procedures at Northwell Health.


Rotator cuff repair surgery is a procedure that helps restore the function and flexibility of the shoulder and relieve the pain that cannot be controlled by nonsurgical treatments. Rotator cuff repair surgery may consist of shaving off bone spurs that are pinching the shoulder or repairing torn rotator cuff tendons and/or torn muscles in the shoulder.


A rotator cuff tear is a partial or total split in the tendinous portion of the four muscles that connect the upper arm bone (the humerus) to the shoulder blade (the scapula). The head of the humerus is held securely but fluidly in the shoulder blade’s socket. This “ball-and-socket” joint must function correctly for you to do things that most people take for granted—such as brushing your hair and putting on your pants—without pain. Because this injury is often chronic (damage done over a significant length of time), rotator cuff tears are seen far more in people over 40.
