Abstract

The invention provides a knee joint prosthesis comprising: a tibial plateau body; an adjusting member with a rotation point contacting the upper surface of the tibial plateau body; a driving mechanismdisposed on the tibial plateau body, wherein the driving end of the tibial plateau body is in contact with the adjusting member, and the driving mechanism drives the adjusting member to rotate aroundthe rotation point to adjust the inclined angle between the adjusting member and the upper surface of the tibial plateau body. The knee joint prosthesis solves the problem in the prior art that the upper surface of a tibial plateau of a femoral condyle prosthesis is always level.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a knee joint prosthesis. Background technique [0002] The knee joint is an important weight-bearing joint of the lower limbs. Degenerative osteoarthrosis of the knee joint is a common disease in the elderly. For severe knee joint diseases, knee replacement surgery should be selected as the treatment method, so as to improve the function of the knee joint in a long-term and stable manner. At present, purely mechanical knee prosthesis is widely used as the prosthesis in knee arthroplasty. [0003] However, in the purely mechanical knee prosthesis in the prior art, the upper surface of the tibial plateau is always horizontal, and the relative position between the tibial plateau and the femoral condyle is fixed, so that the knee prosthesis cannot be adjusted according to the patient's actual anatomy and knee Adjust the actual force of the joint prosthesis in use.
