Knee articulation prosthesis comprising a tibial component (1) on which rests a femoral component (4). The prosthesis is characterized in that, it includes means for preserving or restoring the anterior and posterior crossed ligaments, generators of stability of said knee, and in that the geometry of the condyle portions (5) of the femoral component (4) is such that the anterior and posterior crossed ligaments, whether they are natural or prosthetic, in the femur tibia articulation are subjected to the least stress possible during flexion-extension movements of the knee. The invention also concerns an auxiliary instrument (8) for positioning the crossed ligaments in conjunction with said prosthesis. |
