摘要：
The utility model relates to medicine, namely to traumatology, orthopedics and implantology. The technical result of the utility model consists in hardening and creating a microporous surface of the intraosseous parts of the knee endoprosthesis as a result of blistering pore formation, synthesis of a carbon diamond-like non-porous film on the formed microporous surface and imparting a complex of antimicrobial and antiplatelet properties due to its sequential ion-beam Ag + silver ion modification (silver ions) ( and lanthanum ions (La +). An endoprosthesis of a knee joint with a biocompatible coating contains a femoral component made in the form of a slide made of two parallel arches connected to each other, having on the inside a supporting plane for the distal sawdust of the femur, a tibial component made in the form of a base, on which the limiter is fixed from the opposite sides and a foot with stiffeners, a support pin, a platform of ultra-high molecular weight polyethylene, on one side of which there are made recesses, mated along a cylindrical surface arches with slides of the femoral component, and on the other hand, the arcuate and guide grooves are made in the platform, in which the limiter and the support pin are installed, the slides of the arches of the femoral component and the recesses associated with them in the platform 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 to Asania has on the surface of the intraosseous parts of the endoprosthesis, namely, the fixators of the femoral component and the legs with stiffeners of the tibial component, a microporous layer obtained as a result of preliminary blistering pore formation during ion-beam surface treatment with a helium ion beam (He +) followed by synthesis on the formed microporous the surf
