Millions of people who have suffered from hip pain and arthritis have experienced relief through total hip replacement and restored mobility. Globally, hundreds of thousands of hip replacement procedures are performed each year.
In a total hip replacement surgery, the painful parts of your damaged hip are replaced with artificial hip parts, called a prosthesis, which substitutes for or supplements a joint. The prosthesis consists of three components: a socket, ball, and stem. The outer shell of the socket is usually made of metal and the inner shell consists of plastic; in some cases the entire socket may be plastic. When the metal ball is joined with the socket, the new hip can allow for smooth, nearly frictionless movement.
