<p>PURPOSE: A bearing component of an artificial knee joint is provided to maintain a state in which the bottom of thighbone combination members, which have different curvatures according to location, are stably in contact. CONSTITUTION: A bearing component(100) of an artificial knee joint comprises a groove part(130) which touches with the bottom of combination members. The groove part comprises a multi-curvature part(131). The multi-curvature part comprises: a first curvature part(131a) having a planar shape bent around a center point on a longitudinal center part by a first curvature(R1); a second curvature part(131b) having a planar shape bent around a center point on a longitudinal back part by a second curvature(R2); a third curvature part(131c) having a planar shape bent around a center point on a longitudinal front part by a third curvature(R3).</p> |
