THA: Similar improvement between ceramic-on-ceramic and ceramic-on-polyethylene bearings .
A randomized trial of ceramic-on-ceramic bearing versus ceramic-on-crossfire-polyethylene bearing in total hip arthroplasty: five-year outcomes
J Arthroplasty. 2013 Mar;28(3):485-9. doi: 10.1016/j.arth.2012.07.027. Epub 2012 Nov 892 patients were randomized to evaluate the outcomes of total hip arthroplasty with either ceramic-on-ceramic or ceramic-on-[highly-crosslinked-polyethylene] bearings. Patients were allocated to receive either articulation type, and were followed-up for 5 years. The results indicated that groups did not significantly differ, and both groups experienced significant improvement in pain, function, stiffness and health status one year following surgery that was maintained until final assessment at 5 years. There was also no difference between groups for complication/revision rate.
