Abstract

Polishing biological bearing surfaces of Total Hip and Total Knee Replacements (THR'S and TKR's) are mainly carried out by skilled hand polishers with years of experience and a great eye for detailed inspection. The skilled hand polisher can visualise imperfections on a biological surface and correct them to a high standard but this takes a considerable period of time and years of experience. Minor surface imperfections can reduce the lifetime of joints to that of 5-15 years. An intelligent robotic polisher developed by Zeeko Ltd. along with additional software can reduce these time periods substantially as well as improving the surface form and finish of these freeform biological surfaces are presented in this paper. Initial polishing results are presented for bio compatible alloys. Additionally the development of techniques for "free form" polishing of these surfaces is presented.
