LISBON, Portugal — A comparison of two ceramic-on-ceramic total hip arthroplasty components showed no differences in the prevalence of noise at 1 year, according to data presented at the EFORT Annual Congress.
Claus Varnum, MD, PhD, and colleagues randomly assigned patients undergoing ceramic-on-ceramic THA to receive either a Trident hemispheric cup with an ABG II stem (Stryker; n = 86) or a Trilogy cup with a CLS Spotorno stem (Zimmer Biomet; n = 88). Before primary surgery and at 1-year follow-up, researchers collected the EuroQoL-5D index, EQ-5D VAS and University of California at Los Angeles activity level rating.
“Our primary outcome was prevalence of noises 1 year after total hip arthroplasty and our secondary outcomes were [patient-reported outcome measure] PROM scores 1 year postop,” Varnum said in his presentation.
Other than a higher mean age among patients who received the Trident cup, there were no differences in demographics between the two groups.
“There were some differences in the performance characteristics, mainly due to the different designs of the components,” Varnum said.
Varnum noted no significant differences in the prevalence of noise between the two groups, with 17% and 15% of patients who received the Trident cup and the Trilogy cup, respectively, reporting noise.
“There was no difference between mean UCLA, EQ-5D index and VAS at 1 year after total hip between the two groups,” Varnum said. – by Casey Tingle
