PROBLEM TO BE SOLVED: To provide a tibia bearing insert having a projecting part capable of withstanding the load to an artificial joint of the knee while maintaining the wear resistance of a bearing when the central axis of a distal stem of the tibia bearing insert and the axis of the upper projecting part do not always exist on a same straight line.;SOLUTION: The tibia bearing insert has a first component 12 cooperating with a first long bone 14, a second component 16 cooperating with a second long bone 20 and a bearing component 222. The bearing component 222 includes a reinforcing component 236 and a polymeric material molded to surround at least 99% of the surface area of the reinforcing component 236 by firmly sticking to the reinforcing component 236. The polymeric material is sterilized by a technique of mainly sterilizing surfaces.;COPYRIGHT: (C)2003,JPO
