Prosthetic knee implant for an anterior cruciate ligament deficient total knee replacement

摘要

A prosthetic knee implant accommodates and enhances articulation in an anterior cruciate ligament deficient total knee replacement, throughout flexion and extension, by enabling relative axial rotational movement between the femoral component of the implant and the tibial component about an axis generally parallel to the tibia and passing through the lateral compartment of the implant for allowing anterior-posterior displacement of the medial condyle relative to the lateral condyle of the femoral component during articulation of the prosthetic knee implant between flexion and extension in an anterior direction during articulation from extension to flexion and in a posterior direction during articulation from flexion to extension.
