A joint prosthesis system has two metal implant components (12,14) and a bearing (16). One of the metal implant components has an articulation surface (18,20) for articulation with the bearing. The other metal implant component has a mounting surface (26) for supporting the bearing. An extension (30,32,34,36,38,39) extends out from a junction at the bone-engaging surface of one of the metal components to an exposed end (40,42,44,46,48,51). The extension has a thickness at the junction and comprises porous metal across the entire thickness of the extension at the junction.
