Abstract
An implant having a porous tissue ingrowth structure and a bearing support structure is disclosed. The implant includes a metal insert having a bone ingrowth structure, an intermediate structure and a bearing support structure. A bearing surface is formed from a polymer material and attached to the bearing support structure. The intermediate structure has a porosity sufficient to inhibit the polymer material from translating through the bearing support structure to the bone ingrowth structure.
