A hip implant assembly including a ball and stem. An annular rim separates the ball from the stem and abuts over an exterior reconditioned surface of the femur upon inserting the stem within an interior femur passageway. A cup shaped support seats the ball in articulating fashion via a ligament which extends from the ball and is received within a recess passageway of the cup. The cup includes a mounting surface with a central projecting portion which in turn resistively fits within an undercut recess formed in the ilium bone in communication with a base surface of the reconditioned acetabulum socket. An installation kit assists the preparation of the femur and ilium bones, as well as the installation of the implant body into the conditioned femur end and the cup outer socket support to a reconditioned acetabulum defined in the ilium bone.
