Total Condylar Knee Replacement: Preliminary Report

Abstract

The Total Condylar Prosthesis is a non-hinged unit designed to: replace the patellofemoral articulation; improve fixation of the tibial component by means of a stout central peg; permit accurate and reproducible insertion. The cruciate ligaments are excised to obtain better tibial fixation. Instability has not been a problem except in a few cases of a technical error (removal of excessive bone from the tibia creates instability in flexion). The prosthesis cannot be positioned by "eye" and the instrumentation must be applied exactly.
