Abstract

INTRODUCTION: The main disadvantage of the knee endoprosthesis having the metallic femoral component (FC) and UHMWPE tibial plateau is a relatively high formation of toxic debris of polyethylene. This is a major cause of ostheolysis, gradual bone degeneration and subsequent prostheses loosening. The effort to minimize this abrasion has resulted in the application of ceramic materials to be used for FC. This research works were carried out in the following fields: verification of suitability of the cold isostatic pressing method (CIP) of creating intermediate product of the ceramic FC, experimental research, and FEM stress comparison analysis, of both the metallic and ceramic femoral components.
