摘要：
The utility model relates to medicine, namely to traumatology, orthopedics and implantology. The technical result of the utility model consists in hardening the outer surface of the sled of the femoral component of the knee endoprosthesis as a result of the synthesis of a carbon diamond-like non-porous film. An endoprosthesis of a knee joint contains a femoral component made in the form of a slide made of two parallel arches connected to each other, having a supporting plane on the inner side for the distal sawdust of the femur, a tibial component made in the form of a base, on the opposite sides of which a limiter and a leg with ribs are fixed stiffness, support pin, a platform of ultra-high molecular weight polyethylene, on one side of which there are recesses, mated along a cylindrical surface with arches of a sled of troubles the arched component and, on the other hand, in the platform, arcuate and guide grooves are made, in which a limiter and a support pin are installed respectively, the slide of the arches of the femoral component and the recesses associated with them are made in the form of cylindrical surfaces turning into tangent planes, each of which is located at an angle equal to 5-13 ° to the corresponding plane parallel to the reference plane of the distal sawdust of the femur and drawn through the corresponding line of touch, has The slide surface of the femoral component of the endoprosthesis is a carbon diamond-like non-porous film synthesized during ion-beam treatment in a vacuum environment of carbon dioxide (CO) with an argon ion beam (Ar), which provides increased mechanical strength of the outer surface of the slide of the femoral component of the endoprosthesis design. 2 of FIG.Полезная модель относится к медицине, а именно к травматологии, ортопедии и имплантологии. Технический результат полезной модели заключается в упрочнении внешней поверхностисалазок бедренного компонента эндопротеза коленного сустава в результате синтеза углеродной алма
