Aims: This study reports on the Exeter-Trident total hip arthroplasty (THA) using an alumina ceramic-on-ceramic bearing with 10-year clinical and radiographic follow-up. Patients and methods: Between January 2001 and January 2006, 275 THAs were performed. Mean age at surgery was 52.7 (17–86) years, with 84 patients (33.6%) aged <50 years. The primary outcome was all-cause construct survival at minimum 10 years. Secondary outcomes included functional and noise scores. Radiographs were compared between baseline and latest follow-up and assessed for component loosening, migration and lysis. Results: No patient was lost to follow-up. Mean follow-up for surviving patients was 12.5 (9.5–15.6) years. Kaplan-Meier survival for all-cause revision was 94.0% (95% CI, 90.5–97.5) at 14.3 years. 2 patients had a femoral component fracture. All scores improved significantly at latest follow-up. HSS-NQ for 247 hips (90.2%) at mean 9.1 (7.0–14.4) years post implantation showed most hips (93.1%) reported no more than occasional noise. At minimum 5 years, radiolucency around the acetabular component was observed in 2 hips (0.8%), and lysis at the interface in 1 hip (0.4%). On the femoral side, endosteal lysis was observed in 7 hips. Conclusions: The Exeter-Trident THA with alumina ceramic-on-ceramic bearings performed well in this population. Patients are at low risk of revision in the first decade. However, there is a small risk of stem fracture as a late complication and some patients experience significant noise. [ABSTRACT FROM AUTHOR]
