Abstract
A complete prosthetic of the knee includes a femoral part (6) and a meniscus (3), with said femoral part (6) comprising at least one condyle (3) and a trochlea part, wherein said one or a plurality of condyles each have an external surface, the shape of which complements the respective upper surface of said meniscus (3) in order to obtain a congruence of said surfaces on at least part of the normal flexing range. At least one cavity is implemented in said trochlea such that the femoral part is blocked in its flexion by rotation in the case of negative angles beyond an inferior negative angle limit when the anterior upper edge of the meniscus comes to rest against said cavity.
