ABSTRACT:
A total knee prosthesis comprises a femoral component and a patellar component. The femoral component has a patellar flange into which is built a twist or roller coaster configuration. The patellar component has an off-set dome with respective lateral and medial facets. The configuration of the patellar flange resists forces from a medial to a lateral direction, whilst the lateral and medial facets of the patellar component are respectively shaped to allow area contact and line contact respectively with the femoral component. Also disclosed is a device for intra-operative checking of patellar tracking to allow correct insertion of the femoral and patellar components.
