摘要：
The utility model relates to medicine, namely to traumatology, orthopedics and implantology. The technical result of the utility model is to create a microporous surface of the intraosseous parts of the knee endoprosthesis as a result of blistering pore formation. 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, intraosseous parts the endoprosthesis, namely, the fixators of the femoral component and the leg with stiffeners of the tibial component, have a microporous surface obtained as a result of blistering pore formation during ion-beam surface treatment with a helium ion beam (He). 2 of FIG.Полезная модель относится к медицине, а именно к травматологии, ортопедии и имплантологии. Технический результат полезной модели заключается в создании микропористой поверхности внутрикостных частей эндопротеза коленного сустава в результате блистерингового порообразования. Эндопротез коленного сустава содержит бедренный компонент, выполненный в виде салазок из двух параллельных, скрепленных
