Abstract
A system for converting a first joint prosthesis to a second joint prosthesis in-situ includes a plurality of inserts having a bone interface side and a component facing side and a plurality of articulating components having a cavity configured to receive at least one of the plurality of inserts. The plurality of inserts may be unicompartmental, bicompartmental, or tricompartmental. The inserts may be made of metal and may have a bone contacting surface made of a porous metal. The plurality of articulating components may be unicompartmental, bicompartmental, or tricompartmental. The articulating components may be sized and shaped to cover one or more of the plurality of bone interface components and span a distance therebetween. The articulating components may be made of a polymer.
