Abstract

A knee prosthesis system includes a single-piece tibia plateau with two sliding cavities, a single-piece femur component with two condylar sliding surfaces, the distances between and shapes of which are adapted to the tibial sliding cavities and a pair of unconnected femoral condylar cups, the shapes of the sliding surfaces of which are adapted to the tibial sliding cavities. To be able also to adapt their relative positions, including their distances apart, to the sliding cavities, the system includes a position instrument which ensures this adapted relative position of the codylar cups.
