Abstract
PURPOSE: to evaluate the results of Delta ceramic-on-ceramic (CoC) for total-hip-arthroplasty (THA). METHODS: 261 THA using Delta-CoC, retrospectively analyzed. A 36 mm head was used in 189 cases and a 32/40 mm in the others. The series have been compared to a group of 89 THA with Forte-CoC. RESULTS: The Harris-Hip-Score improved from 49.1 ± 14.3 to 92.0 ± 8.9 (P < 0.001). In the Delta group there were one ceramic fracture and 2 dislocations. Two hips underwent revision. There were one revision in the Forte group for instability and one squeaking hip. CONCLUSIONS: The new ceramic bearings provides a safe bearing for THA, with rare complications.
