Arthroplasty is a surgical procedure that involves the replacement or reconstruction of a joint. This procedure is often used to relieve pain and improve function in individuals who have severe joint damage, such as from arthritis or injury. Common arthroplasty procedures include hip and knee replacements, as well as shoulder and elbow replacements. Arthroplasty can help improve mobility, reduce pain, and enhance the overall quality of life for individuals with degenerative joint conditions.
