A total hip prosthesis comprises a cotyloid implant consisting of a metal cup to be anchored in the acetabulum, a polyethylene insert which provides an intermediate implant inserted into the cavity of the cup, and a femoral implant consisting of a cap having an outer convex surface which is slidably postionable within the insert cavity. An inner concave surface of the femoral implant is implantable on the head of the femur. The prosthesis is particularly suitable for endo-articular implantation.
