Abstract
An artificial knee joint includes: a femoral component including a medial condyle and a lateral condyle; and a tibial component including an inner sliding surface that receives the medial condyle and an outer sliding surface that receives the lateral condyle. A curvature radius of each of the inner sliding surface and the outer sliding surface in a medial-lateral direction increases from an anterior side toward a posterior side within a predetermined range in an anterior-posterior direction. In the medial-lateral direction, the inner sliding surface and the outer sliding surface are positioned inward such that a middle point between a lowest point of the medial condyle and a lowest point of the lateral condyle in a knee extended position is shifted inward relative to a center of the tibial component by 2 to 10% of a width of the tibial component.
