A cementless hip resurfacing prosthesis is provided. The prosthesis comprises a metallic cap that is fitted over the individuals femoral head to provide a new acetabular articulating surface. The metallic cap is affixed to the femur via a locking means extending from the inner surface of the metallic cap, which engages with a complimentary tubular fixation means attached to a plate. The plate is affixed to the lateral surface of the femur via a fixation screw, which extends through the fixation means, through the locking means, and engages with a complimentary threaded portion within the locking means. The plate is further affixed to the femur via a plurality of cortical screws, which also act to distribute the forces from the hip joint to avoid stress shielding and bone resorption effects commonly associated with hip replacement prostheses. Furthermore, the present invention is designed to reduce shear stresses on the femoral neck.
