Lower metal levels and volumetric wear seen with ceramic-on-metal THA bearings

Extract only
A prospective randomized trial with up to 5 years follow-up found lower blood chromium levels with ceramic-on-metal total hip arthroplasty articulations vs metal-on-metal articulations. For total hip arthroplasty (THA), “The best bearing surfaces we have available in the laboratory are ceramic-on-metal, ceramic-on-ceramic and metal-on-metal,” investigator Anton Schepers, MB, FCS(SA), said at the 26th Annual Current Concepts in Joint Replacement Winter Meeting, here. “I feel ceramic-on-metal is potentially one of the bearing surfaces of the future.”
