A minimally invasive surgery used for the diagnosis and treatment of conditions affecting joints. Small incisions are made into the shoulder to insert small ports to allow a camera to visualize the inside of the shoulder. The rotator cuff consists of muscles and tendons that form a cuff over the joint. The tendons can be torn from injury or overuse. Anchors (implants made of synthetic or metal materials) are attached to tie the tendon back to the bone.
