A hip-joint prosthesis which provides for universal motion about three transverse pivot axes comprising a femoral member adapted to be coupled to the femur and a cup assembly partially receiving the femoral member. The cup assembly is slidably received in the acetabulum. Motion about one of the pivot axes can occur in the prosthesis and motion about the other two pivot axes is forced to occur between the cup assembly and the acetabulum.
