Compared with other findings regarding ceramic materials in joint articulations, results published in The Journal of Arthroplasty showed a higher rate of ceramic fracture with third-generation ceramic-on-ceramic (CoC) articulations for total hip arthroplasty.
Researchers retrospectively reviewed 527 patients who underwent primary total hip arthroplasty using a third-generation CoC articulation.
At an average follow-up of 5.9 years, seven hips exhibited liner fracture and 14 hips exhibited head fracture, and squeaking occurred in eight hips. Researchers found a revision rate of 5.2%. However, when cases of ceramic head and liner fracture were excluded from the analysis, 1.6% of patients underwent revision surgery. Results of the study showed a mean 10-year survivorship of 93% with revision for any reason as the end point. Researchers found 28-mm heads with short necks had the worst survivorship: 89% at 10 years. – by Casey Tingle
