A labrum is a protective cuff of cartilage found in ball and socket joints like the hip and shoulder. They provide more stability, cushioning and a full range of motion for these shallow joints. A tear in the labrum, known as a labral tear, is caused by injury or overuse and can lead to pain and "catching" of the joint while moving.
Labral repair surgery aims to repair unstable shoulders with staples, anchors or sutures. The procedure is usually performed through arthroscopy, which allows the doctor to view the tear through a small camera and perform the procedure through tiny incisions.
