Abstract
A joint prosthesis system is suitable for cemented fixation. The system has two metal implant components and a bearing. One of the metal implant components has an articulation surface for articulation with the bearing. The other metal implant component has a mounting surface for supporting the bearing. One of the metal implant components includes an extension, such as a stem or pegs, with an exposed outer surface. 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.
