Abstract
A bone cutting fixture assembly for use as guide for a cutting blade in shaping a distal end of a femur to receive a component of a knee prosthesis is provided. The assembly has a centrally located, elongated support structure, made of a polymeric material, having a trapezoidal cross section, pairs of adjacent blade guide appendages supported therein so as to define four cutting planes, and two outrigger portions extending therefrom defining anchor points in distal ends thereof. The assembly defines a substantially flat support plane and has spaced apart anchor points positioned so as to enable secure fixing of the fixture to a femur by fixing devices.
