Abstract
A modular knee prosthesis assembly for the replacement of a portion of the knee joint is provided. The assembly has a femoral component that is formed to include first bearing surfaces and first means for demountably receiving an optional femoral stem member. The assembly also has a tibial component that is formed to include a platform and second means for demountably receiving an optional tibial stem member. The assembly includes a separate tibial insert that is configured to be supported by the tibial component platform. The tibial insert is formed to include second bearing surfaces that are configured to mate with the first surfaces on the femoral component to permit pivotal movement between the femoral component and the tibial component.
