PROBLEM TO BE SOLVED: To induce a bend/extension motion and a rotation motion simultaneously.;SOLUTION: The invention comprises: a femur component FC comprising an internal condyle MC comprising a rear condyle side ball center DO2 in which diameter to a joint lowest point is reduced as an angle is increased from a constant bend angle, and an external condyle LC comprising a rear condyle side ball center DO1 in which diameter to the joint lowest part by bend, is constant; and a tibia component TC in which an internal condyle side joint surface in which, a lowest point on the rear condyle side of the internal condyle part following to bending of a knee is a horizontal level, and an external condyle side joint surface which moves to a rear inside distal direction with rotation following to bending, are formed as negative models of both condyle parts of a femur.;SELECTED DRAWING: Figure 8;COPYRIGHT: (C)2017,JPO&INPIT
