Abstract

A posterior stabilized knee orthopaedic prosthesis assembly includes a tibial bearing, a primary femoral component, and a revision femoral component. Each of the primary and revision femoral components is configured to separately articulate with the tibial bearing. However, each of the primary and revision femoral components has different geometry. The primary femoral component includes a posterior cam having a posterior cam surfacing including a concave cam surface and a convex cam surface. The revision femoral component includes a posterior cam having only a convex cam surface.
