Use of either a ceramic-on-ceramic or ceramic-on-highly-crosslinked-polyethylene bearing in total hip arthroplasty resulted in excellent patient-reported and radiographic outcomes at 10 years postoperatively, according to results.
Researchers randomly assigned 92 patients undergoing total hip arthroplasty (THA) to a ceramic bearing group or a polyethylene bearing group. Researchers used the WOMAC Index and the RAND 12-Item Health Survey to assess patients preoperatively and at 1 year, 5 years and 10 years postoperatively.
In this follow-up to previously reported 5-year outcomes, results showed 79% of patients had radiographic or clinical follow-up at 10 years postoperatively. Researchers found at 10 years patients retained improvements found at 5 years in both the WOMAC Index and RAND 12-Item Health Survey with no group differences. In either group, patients experienced no failures or loss of fixation related to bearing surfaces or wear, according to results. Researchers noted revisions in three patients in the polyethylene group related to recurrent dislocation, of which two revisions were performed within 2 years of surgery while one revision was performed at 7 years postoperatively. – by Casey Tingle
