A joint prosthesis system (10) is suitable for cemented fixation. The system has two metal implant components (12,14) and a bearing (16). One of the metal implant components has an articulation surface (18,20,22) for articulation with the bearing. The other metal implant component has a mounting surface (26) for supporting the bearing. One of the metal implant components includes an extension (30,32,34,36,38,39), such as a stem or pegs, with an exposed outer surface (79). The metal implant component from which the extension extends comprises titanium and the exposed outer surface of the extension comprises a different form of titanium. A method of making the joint prosthesis is also disclosed. |
