Assembly of femoral (1) and patellar (2) components for a knee prosthesis, and of which the trochlear slopes (11), the femoral condyles (12) and the rotulian facets (22) have the same curvature and shape, preferably spherical; the femoral component has a transverse split or condilotrochlear groove between the trochlea and each of the condyles (14). The cinematic interaction between the design of the rotulian crest (21) and the trochlear throat (13) provides for a smooth displacement of the rotulian component from the trochlea to the condyles and vice versa without friction with the condilotrochlear groove (c) and maintains constantly a contact of the superficial type with the femoral component. <IMAGE> |
