Patients with shoulder pain or limited shoulder function may be candidates for arthroscopic shoulder surgery. Most people who suffer from a shoulder injury and who have not found the relief they need through nonoperative treatments may benefit from a minimally invasive surgical procedure. The information in this brochure will help you better understand the anatomy and function of the shoulder, as well as the effects on the shoulder of a rotator cuff tear or the condition known as “shoulder instability.” In addition, it will guide you through the steps of arthroscopic shoulder surgery for the treatment of these conditions.
