New ceramic-on-ceramic bearing for THA found reliable, durable in study
Ceramic-on-ceramic bearings for total hip arthroplasty proved reliable and durable at 6 years mean follow-up with no cases of ceramic breakage or complications related to the acetabular component reported, according to study results.
Researchers analyzed demographics, surgical technique, complications, and the clinical and radiological outcomes for 115 patients who underwent 133 total hip arthroplasties (THAs) with what, at the time, the newest generation of ceramic-on-ceramic bearings to be FDA approved.
Compared with their preoperative Harris Hip Scores and University of California Los Angeles (UCLA) activity rating, there was significant improvement postoperatively in the patient’s outcomes with mean Harris Hip Scores of 88.1 points and mean UCLA activity scores of 6.2 points. Researchers found Harris Hip Score results were excellent in 64% of hips and poor in 11% of hips. Harris Hip Scores. The UCLA activity scores were significantly higher among the patients with 36 mm femoral heads compared to patients with 28 mm femoral heads, the study results showed. There were no intraoperative cases of ceramic breakage or chipping in the series. Two patients required revision surgery; one each for deep infection and anterior hip dislocation. – by Casey Tingle
