<p>A knee prosthesis (10) of two of more pieces including a patellar femoral flange piece (41) and a condylar piece (42) is disclosed. The patellar femoral flange piece (41) has a patellar engaging surface (43) shaped to allow anatomical tracking of a natural prosthetic patella (2). The patellar femoral flange piece (41) has a superior bone engaging surface (46) and a patellar engaging surface (43) defining a portion of an inferior articulating surface. The use of multiple pieces reduces the size of the incision needed for implantation and allows assembly of the implant within the body.</p>
