Posterior stabilized type complete knee prosthesis, has femoral condyles of femoral implant and glenoid surfaces corresponding to intermediate plateau are such that medial lobe engages in round cavity during flexion movement of joint
The prosthesis has a medial prominence (13) presenting an upper return (15) directed from a posterior side of an intermediate plateau (2) which presents a posterior medial protrusion (14). A medial lobe presents a congruent round shape to that of a round cavity (16). Femoral condyles (7) of a femoral implant (1) and glenoid surfaces corresponding to the plateau are such that the lobe engages in the cavity during a flexion movement of a joint along a globally direction perpendicular (P) to a line (L) extending from a anterior zone of the protrusion to a posterior end of the return.
