Title: Outcomes of ceramic-on-ceramic total hip arthroplasties after ten years


We conducted a prospective follow up for 238 patients who underwent ceramic on ceramic hip arthroplasties between January, 2011 and December, 2015. Out of these, 205 patients (86.1%) had uncemented fixations and 33 patients (13.9%) had cemented fixations with THA using a CoC femoral head and liner. For each patient, WOMAC and SF-12 scores were measured at six weeks, six months, two years, and five years. Radiological follow up to 10 years. The patients who received revision surgery were identified in the database. A Kaplan-Meier analysis was undertaken to estimate survival.

Results: The mean preoperative WOMAC and SF-12 scores were 39.83±12.29 and 30.07±2.18, respectively. At 5 years, the mean WOMAC score had improved from 39.83 ± 12.29 to 90.33 ± 5.79 (p < 0.01), Wilcoxon signed-rank test; the mean SF-12 score had improved from 30.07 ± 2.18 to 34.31 ± 2.32  (p < 0.01, Wilcoxon signed-rank test). Four patients (1.7%) got revision within 10 years postoperatively.

Conclusion: The CoC THA showed statistically significant clinical improvement in WOMAC score and functional score of SF-12 after 5 years follow-up with satisfactory survival after 10 years.
