92 patients scheduled for total hip arthroplasty were randomized to either ceramic-on-ceramic or ceramic-on-highly-crosslinked-polyethylene articulations. A total of 68 patients were available to provide either clinical or radiographic data at the 10-year follow-up. Results demonstrated no significant differences between groups at the 10-year follow-up for the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and RAND 12-Item Health Survey. No failures related to implant wear were noted. Three revisions in the polyethylene group were performed due to recurrent dislocation.
