Abstract: According to the invention, the system enables a preoperative study to be carried out wherein the tibia and/or femur is modelled on a computer (6) in 3D, the ideal cutting plane is defined and the position of the resection instruments (1, 2, 3) used to cut the bone is modelled. Additionally, according to the invention, the system enables redefinition of the ideal cutting plane and the positioning and orientation of the resection instruments (1, 2, 3) on the tibia and/or femur, in such a manner that the plane of the slot (4) of the cutting guide (3) through which the cutting tool is introduced coincides with the ideal cutting plane.
