Abstract
A prefabricated joint is employed for the prosthetic joint. The joint includes prefabricated socket, ball, and capsule. The capsule is attached from the ball to the socket. The capsule seals the area between the ball and socket and prevents wear debris from entering the body cavity. In the case of the hip joint, the doctor need only attach the prefabricated unit to the femoral unit to connect the prosthetic joint after the prefabricated unit and femoral unit have been placed into the acetabular and femur, respectively.
