Artificial knee for cruciate ligament replacement

摘要

PROBLEM TO BE SOLVED: To provide a prosthesis that reproduces the functions provided by both ACL and PCL for the purpose of providing anatomically more appropriate TKR. A knee prosthesis has the ability to move between an extension position and a flexion position. The knee prosthesis is one of a femur component configured to be attached to the femur, a tibial component configured to be attached to the tibia, and a femur component and a tibial component. Fixedly connected to the post, and defined above the other of the femoral and tibial components, configured to be engaged by the post in either the extended or flexed position of the knee prosthesis Includes cam depressions that have been made. The knee prosthesis may also include an artificial ligament that extends between the femoral and tibial components. Posts and ligaments mimic either ACL or PCL. [Selection diagram] FIG. 7A
