Abstract

ABSTRACT

Metaphyseal filling augments fabricated from porous tantalum provide a novel alternative for managing massive bone loss during revision total knee replacement. These implants have the advantage of excellent initial fixation, high porosity providing increased bone ingrowth, and relatively low stiffness for improved remodeling of host bone. This article outlines the surgical technique for managing massive bone loss during revision total knee replacement using trabecular metal cone augments.
