Managing bone loss with augmentation.

Abstract

Augmentation blocks are effective ways of treating the problem of bone loss on the distal and posterior femur. They allow accurate and durable reestablishment of the distal and posterior joint line in revision total knee replacements. They are particularly appropriate in revisions being carried out in elderly, osteopenic patients with severe deformities or instabilities. Revision instrumentation can and should philosophically and mechanically remind one of and be consistent with primary total knee instrumentation.
