Trusted technology, trusted performance

Powered by our proprietary combination of the POLARSTEM Hip Reconstruction System, R3 Acetabular System and OXINIUM Technology, with the best survivorship figures of any total hip construct at 10 years, according to the world’s largest national joint registry.*1

The combination of unique OXINIUM Oxidized Zirconium heads with a highly cross-linked polyethylene (XLPE) liner has been shown to result in the lowest revision rate of all modern bearing combinations in four national joint registries.**2-5

**Although the Ceramicised Metal/ XLPE combination has the lowest reported cumulative percent revision at 10 years, these results should be interpreted with caution. This bearing is a single company product used with a small number of femoral stems and acetabular component combinations. This may have a confounding effect on the outcome, making it unclear if the lower rate of revision is an effect of the bearing surface or reflects the limited combination of femoral and acetabular prostheses.3
