Hip and knee parts are used in replacement surgeries, the Hospital for Special Surgery explains. The replacement parts or implants vary from fixed-bearing to rotating platform, used mostly for total knee replacements. The fixed-bearing implant is a joint that locks onto the tibia on the bottom and femur on top. The rotating platform allows the part attached to the tibia moves to allow greater range of motion. Partial knee replacements use only partial implants for the knee joint.

A typical hip replacement surgery is the hip arthroplasty, states the Hospital for Special Surgery. In this procedure, part of the femur along with the ball head that fits into the hip socket is replaced with a prosthesis. The socket of the hip is fitted with a cup-shaped implant in which the ball implant rests. In a partial replacement or hip resurfacing, only the head of the femur is replaced with a prosthesis. The implants are either made out of metal or ceramic.
