Abstract
A tibial component of a replacement knee prosthesis includes a tibial tray for connection to a suitably prepared tibia. The upper surface of the tray carries one or more bearing components provided with means for altering the position of the tibia relative to its co-operating femur by alternatively altering one or more of the following variables: medio-lateral offset, antero-posterior offset, antero-posterior tilt, tibial rotation and tibial condyle depression profile. The tray carries either one bearing component which cooperates with both femoral condyles, or two distinct bearing components, each of which cooperates with a single femoral condyle.
