Short-term Wear Analysis and Clinical Performance of Large Ceramic Heads on Highly Cross-linked Polyethylene in Young and Active Patients

We hypothesized that large ceramic head articulation against highly cross-linked polyethylene in young and active patients would have high safety for dislocation and fracture and low wear rates. Wear analysis of 32 hips with 36-mm Delta ceramic femoral heads (CeramTec, Plochingen, Germany) on highly cross-linked polyethylene was performed using Roman software (Robert Jones & Agnes Hunt Orthopaedic Hospital, Oswestry, United Kingdom). The mean age was 56.8 ± 6.5 years, and the mean follow-up was 2.6 ± 0.5 years. The mean wear rate was 0.022 ± 0.11 mm/year after the bedding-in period. There were no reoperations. The early results of large ceramic heads in young and active patients demonstrate high safety and efficacy.
