Abstract

After total knee replacement, the breakage of implant is unusual. We have been experienced the two cases, one is the porous tibial plate breakage that Miller/Galante total knee system(MG TKS) and the other is the metal-backed polyethylene patellar component breakage with low contact stress(LCS) pros-thesis. Revisions have been performed by using Nexgen and modular posterior stabilized P.F.C. total knee system. Considerations of these causes are habitual abrupt hyperflexion of the knee and weight bear-ing. So we need to careful observation of long term clinical, radiological and survival results of total knee prosthesis in regard of the breakage of implant.
