Shoulder surgery can potentially restore pain-free range of motion and full function to a damaged shoulder joint. Surgery is a treatment for a variety of conditions in your shoulder joint. These include rotator cuff tears, shoulder dislocations, and shoulder separations.
Arthroscopy is surgery using an arthroscope. An arthroscope is a long, thin instrument that contains a small camera. It is inserted into the joint through an incision over or near the joint. The camera transmits pictures of the inside of your joint to a video screen that your surgeon views while performing surgery.
