Abstract

Abstract The purpose of this study was to evaluate the clinical and radiological results of Metasul cups cemented into reinforcement rings for young and active patients. Twenty-three total hip arthroplasties with Metasul cups were cemented into Muller reinforcement rings. Mean follow-up was 6.1 years (5-10). At final follow-up, the Harris hip score increased from 62.2 (39-85) to 95.2 (84-100, P = .01): no revision was undertaken for aseptic loosening or fixation failure. Considering reoperation and bearing revision as end points, survival rates were 95.8% and 100%, respectively. The mean blood concentrations of chromium, cobalt, and titanium were 1.85 μg/L, 1.24 μg/L, and 9.62 μg/L, respectively. A longer follow-up is mandatory, but it seems possible to use hard-on-hard bearings with metallic rings in young patients during hip revisions or in dysplastic cases with encouraging intermediate follow-up results.
