Abstract

A prosthesis includes an implant defining an attachment surface thereon. A porous insert is selectively coupled to the implant. The porous insert is adapted to be received at the attachment surface of the implant in a retained position. The porous insert is adapted to facilitate tissue ingrowth. In one embodiment the implant comprises a femoral component. The femoral component comprises an inner condylar portion having a first and second lateral sidewalls, an anterior wall and a posterior wall defining a box. The box defines the attachment surface. In other embodiments, the implant comprises a hip stem and an acetabular shell.
