Abstract

The invention provides a knee joint prosthesis, which comprises a tibial plateau, wherein a first arc grove is arranged at the upper surface of the tibial plateau; a gasket platform rotatably mountedon the tibial plateau, wherein a second arc-shaped groove corresponding to the first arc groove is formed in the lower surface of the gasket platform; and balls installed in the first arc groove and the second arc groove, wherein the tibial plateau supports the gasket platform through the balls. According to the technical scheme, the problem of poor flexibility of the knee joint prosthesis in theprior art is effectively solved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a knee joint prosthesis. Background technique [0002] The knee joint is the main joint of the lower limbs, and its structure and function are the most complex among human joints. At the same time, the knee joint is also one of the most vulnerable joints. Knee replacement surgery is an effective means of treating severe lesions and deformities of the knee joint. Successful knee replacement surgery can significantly relieve knee pain, improve knee joint function, and ensure the stability of the lower limbs and the needs of daily life. joint mobility function. [0003] In the related technology, after the knee joint prosthesis is implanted into the human body, a moment acts between the spacer platform and the tibial platform during the knee joint movement, and there will be fretting at the interface, which will cause the spacer platform to wear and generate debris, causing Osteolys...
