Instrumentation for the production of fixing surfaces for a knee joint endoprosthesis
First Claim
1. An instrumentation for the production of fixing surfaces for a knee joint endoprosthesis to be fixed to the femoral condyle that is adjacent to the knee, and to the tibial head, characterized by a rotary milling head (2) which is fixable in relation to the longitudinal axis of the femur (40) and tibia, respectively, by fastening means and which, in relation to this longitudinal axis, is angularly adjustable in a stable stop position by being pivoted, defining milling planes (cutting planes I to V), and which is displaceable in the set milling plane (cutting planes I to V), covering same and working as a face milling cutter or as a cylindrical milling cutter.
