While it may be a very common injury, shoulder dislocation is quite painful to experience. A Bankart lesion occurs when a portion of the ring of cartilage around your shoulder socket has been torn. Sometimes a small piece of the bone in this area gets pulled off as well. Arthroscopic Bankart repair is also a minimally invasive way to help fix the injured cartilage and restore stability. It is commonly used for people who experience recurrent shoulder dislocation episodes, but may also be recommended after a single dislocation especially in younger people, as the risk of another dislocation is quite high.
