Management of severe bone loss in revision total knee arthroplasty

Severe bone loss may be encountered in a multitude of scenarios during revision total knee arthroplasty, such as osteolysis and component subsidence, and is a challenge for the joint replacement surgeon. The appropriate reconstructive techniques are dictated by the quantity and location of the tibial and/or femoral bone loss. When the bone loss is severe, reconstruction of the supporting tibial or femoral platform and filling of the metaphyseal voids can be performed with newly developed highly porous metaphyseal cones. This study details the indications, surgical technique, and available clinical results for this promising reconstructive strategy, which uses the mechanical and biologic benefits of highly porous metal technology.
