Abstract
A knee prosthesis for use in a total knee replacement surgical procedure may include a femoral component, a tibial component and a meniscal component. Optionally, the prosthesis may also include a patellar component. The femoral component may include a bone attachment side and a joint facing side, the latter including an anterior joint surface, a posterior joint surface having a cross-sectional shape defining a portion of a cylinder, and medial and lateral grooves between the anterior and posterior joint surfaces. The meniscal component may include a number of features designed to mate with the femoral component to provide relatively natural movement and range of motion about the knee joint as well as stability and resistance to wear and tear.
