Endoprosthetics of the knee joint

Unlike the hip joint, which consists of a ball (head) and a cavity, the knee joint consists of a multitude of elements that are in a complex interaction. The first prostheses of the knee joint looked like a hinge consisting of two parts, pivoted in the middle by an axle. This design had an advantage - it could work even with damaged bundles. However, such prostheses did not function for long. The problem was that during walking there is always some element of rotation in the knee joint. This led to loosening and prolapse of the prosthesis. The modern design of the knee arthroplasty consists of the femoral, tibial components and the implant of the patella.

The technology of its application provides for the use of natural intact ligaments as stabilizers. Thus, the natural movements in the joint remain and the risk of destruction of the endoprosthesis is reduced.
