A knee implant includes a femoral component having first and second
femoral component surfaces. The first femoral component surface is for
securing to a surgically prepared compartment of a distal end of a femur.
The second femoral component surface is configured to replicate the
femoral condyle. The knee implant further includes a tibial component
having first and second tibial component surfaces. The first tibial
component surface is for contacting a proximal surface of the tibia that
is substantially uncut subchondral bone. At least a portion of the first
tibial component surface is a mirror image of the proximal tibial
surface. The second tibial component surface articulates with the second
femoral component surface.
