Abstract
A patellar implant includes a posterior portion and an anterior portion. The posterior portion may define an articulating surface and a first retaining feature. The anterior portion may define a tissue engaging portion and a second retaining feature adapted to advance into a mechanical interlock with the first retaining feature in an assembled position. The mechanical interlock between the first and second retaining features may cooperate to resist separation of the posterior and anterior portions in the assembled position.
