Abstract
The invention relates to a knee joint prosthesis system adapted to replace the articulating knee portion of a femur and a tibia. The knee joint prosthesis system includes a first femoral component and a second femoral component. The first femoral component includes a first femoral engagement region and a first condylar portion having a first femoral bearing surface. The first femoral engagement region is operable to engage a resecting engagement surface of the femur and the first condylar portion includes a first posterior region having a first thickness. The second femoral component includes a second femoral engagement region and a second condylar portion having a second femoral bearing surface. The second femoral engagement region is operable to engage the resected engagement surface of the femur and the second condylar portion includes a second posterior region having a second thickness. The second thickness is larger than the first thickness and the first femoral engagement region is substantially the same as the second femoral engagement region, whereby a surgeon may select either the first femoral component or the second femoral component for attachment to the femur.
