Shoulder replacement surgery is a procedure to relieve pain and restore function to a damaged shoulder joint. It involves replacing worn or damaged parts of the shoulder with artificial components, usually made of metal and plastic. This surgery is often recommended for severe cases of arthritis, rotator cuff injuries, or shoulder fractures that have not improved with non-surgical treatments. The procedure may be complete or partial, depending on the extent of the damage. After surgery, patients typically go through a rehabilitation program to regain strength and mobility. The goal of shoulder arthroplasty is to relieve pain, improve range of motion, and improve quality of life.
