ADAPTIVE BONE REMODELLING OF ALL POLYETHYLENE UNICOMPARTMENTAL TIBIAL BEARINGS

Background:  Failure of unicompartmental knees is either by progressive osteoarthritis or by failure of the prosthesis. Prosthesis failure can be because of either the actual component itself or its fixation method. Specifically, the tibial component may wear, loosen or subside into the tibial metaphyseal bone. We modelled all polyethylene tibial components and investigated the periprosthetic adaptive remodelling of the bone.
