ABSTRACT:
The invention is directed to an orthopaedic implant (30, 50) including a metallic body (42, 52) having a metallic bearing surface (44, 54). The orthopaedic implant also includes a device (46, 56) for applying an electromotive force to the metallic bearing surface (44, 54). The electromotive force may result from a galvanic couple with the bearing surface (44, 54) or a direct current power source (56) connected with the bearing surface (44, 54).
