Abstract
A patellar implant for total or partial prosthesis of the knee joint incorporates an outer articular surface and an inner articular surface provided to cooperate respectively with an outer side and an inner side of a femoral trochlea or of a femoral prosthetic component. The inner and outer articular surfaces are separated by a transition ridge which is curved, as viewed from a front of the implant, so as to be concave facing the outer articular surface. The outer articular surface is concave in a plane parallel to a sagittal plane and in a transverse plane of the knee joint.
