Hip replacement surgery, also called total hip arthroplasty, involves removing a diseased hip joint and replacing it with an artificial joint, called a prosthesis. Hip prostheses consist of a ball component, made of metal or ceramic, and a socket, which has an insert or liner made of plastic, ceramic or metal. The implants used in hip replacement are biocompatible — meaning they're designed to be accepted by your body — and they're made to resist corrosion, degradation and wear.
Hip replacement is typically used for people with hip joint damage from arthritis or an injury. Followed by rehabilitation, hip replacement can relieve pain and restore range of motion and function of your hip joint.
