A total hip replacement is a surgical procedure that removes the arthritic ball of this top thighbone (femur) as well as damaged cartilage through the hip socket. The ball is replaced by having a steel or ball that is ceramic. After the damaged femoral mind is eliminated, a stem is either glued or “press fit” to the center associated with the femur. The socket is replaced by having a synthetic liner. This liner is generally fixed in a very steel shell. This produces a smooth joint that is functioning.
