The operation replaces the damaged surfaces of the shoulder joint. It consists of a metal replacement for the ball component and a plastic cup for the socket. The main reason for doing this operation is to reduce the pain in your shoulder. You may have more movement in your shoulder but this will depend on how stiff your shoulder was before surgery and whether the muscles were working normally or whether they were damaged. Before you have the operation the doctors will be able to see if there is any significant damage to the muscles from this information they will be able to give you a realistic idea of what movement you can expect after surgery. Sometimes only the ball part of the joint is replaced and sometimes the joint is resurfaced.
