Biomechanical Changes of the Tibial-femoral Joint of the Knee Joint with Fixed and Moving Axes Under
Total knee arthroplasty is an effective method for treating knee diseases, but there is no unified view on the advantages and disadvantages of fixed-axis and mobile-axis knee prostheses. In the past, there have been comparative verifications of the two prostheses, but most of which are static simulations. In this paper, a finite element model of a healthy knee joint was built; then a knee joint containing the above two prostheses was established; finally, by dynamically simulating the knee flexio...
