This is a surgical procedure whereby the diseased cartilage and bone of the hip joint is surgically replaced with artificial materials. The normal hip joint is a ball and socket joint. The socket is a “cup-shaped” component of the pelvis. The ball is the head of the thighbone (femur).
Total hip joint replacement involves surgical removal of the diseased ball and socket and replacing them with a metal or ceramic ball and stem inserted into the femur bone and an artificial plastic or ceramic cup socket.
In certain cases the surgeon may advice hip resurfacing, here the femoral head is not removed, but is instead trimmed and capped with a smooth metal covering. The damaged bone and cartilage within the socket is removed and replaced with a metal shell.
