Abstract

Background: Enhanced wear resistance of ceramics in general and improved mechanical characteristics of composite ceramics in terms of strength and resistance meet the demands for application in TKA.The aim of this prospective international multi-centre study was to evaluate the 5-year clinical and radiological outcomes of an unconstrained TKA with a composite ceramic femoral component. Methods: A total of 107 patients (109 knees) underwent TKA with the MULTIGEN-PLUS Ceramic Knee at seven centres in three European countries. Clinical and radiological assessments were performed preoperatively and postoperatively at 3, 12, 24 and 60. months, using HSS, WOMAC, SF-36 and standardised radiographs. Results: Mean HSS and WOMAC increased significantly from 55.1. ±. 11.5 (21-83) and 48.1. ±. 16.6 (3-90) preoperatively to 85.6. ±. 9.6 (49-98) and 73.3. ±. 20.4 (17-100) at 60. months. Mean SF-36 showed significant improvements in patients' quality of life (49.1. ±. 17.6 (12-96) preoperatively versus 67.7. ±. 23.1 (12-100) at 60. months). Non-progressive radiolucent lines (
