A knee prosthetic including a tibia part ( ), which includes a tibia plate ( ) that co-operates with at least one meniscal element by a first side ( ), and co-operates with a tibia resection plan by a second side ( ), including a tibia pin ( ) connected with the tibia plate ( ), which penetrates into the tibia to fix the tibia part ( ) into it; and at least one compensating tibia block ( ), which fits flatly between the second side ( ) of the tibia plate ( ) and the tibia itself, in order to compensate for a lack or absence of local bone tissue between the tibia and the resection plan. This tibia block ( ) also co-operates with said tibia part ( ) by way of complementary fixating means ( ) that are implemented on the tibia block ( ) and tibia part, wherein the complementary fixating means are of the pin ( ) and hole ( ) type and are implemented on the tibia block and the base ( ) of the tibia pin.

Knee prosthesis comprising a tibial wedge

A knee-joint prosthesis including a tibial insert ( ) between a tibial plate ( ) provided on its outer surface with means for fixing to a tibia, and a femoral part comprising a condyle provided with means for fixing to the femur, the tibia insert ( ) being mounted on the tibial plate ( ) and comprising at least two upper surfaces ( ) complementary in shape with the outer surface of the condyles, a tenon ( ) is fixed to the inner surface of the tibial plate ( ) and projects upwards and comprises an oblong part ( ) extending parallel to the inner surface of the tibial plate ( ), and the tibial insert ( ) has a cavity ( ) in which the oblong part ( ) engages with possibility of rotation and translation of the tenon ( ) relative to the tibial insert ( ).

Total knee joint comprising an insert movable relative to a tenon

Knee prosthetic, incorporating a prosthetic femoral component designed to be fixed to the furthest or nearest extremity, of the femur, a tibial prosthetic component designed to be fixed to the nearest or upper extremity of the tibia and at least one intermediary mobile meniscoid prosthetic involving a lower surface working together by sliding with the complementary upper surface of the tibial component, and at least one upper concave surface working together by sliding with a lower condyloid convex surface of the femoral component, characterised by the fact that the upper surface of the tibial component and the lower surface of the meniscoid component are flat and sloped in the same angle from the top at the rear towards the front.
