摘要：
An orthopaedic joint prosthesis comprises first and second articulating components having respective bearing surfaces in contact with one another. The material of the first bearing surface (14) comprises a metallic material and the material of the second bearing surface (6) comprises a ceramic material. The hardness of the metallic material is at least about 2500 MPa, and the hardness of the ceramic material is greater than that of the metallic material by at least about 4000 MPa.
