Study Results: Smith+Nephew’s OXINIUM on XLPE for Total Hips

Smith+Nephew announced publication of new clinical evidence further validating the performance of its proprietary OXINIUM Oxidized Zirconium on highly cross-linked polyethylene (XLPE) for total hip replacement. Study results indicate that procedures using OXINIUM on XLPE were associated with the lowest risk of revision of all bearing combinations for any reason beyond 10 years.

Specifically, results showed:

• 1.96% cumulative incidence of revision at 10 years compared with the average of 4.79% for primary hip replacements
• 48% reduction in risk for aseptic loosening compared to metal on XLPE
• Lowest revision risk vs. all bearing combinations in patients less than 55 years old
• Lower risk of revision compared to ceramic-on-ceramic hip bearing combinations

The new analysis corroborates a similar report from the Australian Orthopaedic Association National Joint Replacement Registry and publications referencing the Italian Registry and the Dutch Arthroplasty Register, confirming the positive effect that modern bearing surface combinations like OXINIUM on XLPE have on total hip procedure survival.

“Registries throughout the world have highlighted the performance of OXINIUM for total hip arthroplasty. This publication is further evidence of the success of our truly differentiated and proven technology,” said Skip Kiil, President of Global Orthopaedics at Smith+Nephew. “THA is considered one of the most clinically successful procedures in modern medicine, and OXINIUM on XLPE continues to raise the bar for acceptable revision rates.”
