Crosslinking reduced wear rate of polyethylene in laboratory studies.
Reduction of debris compared to standard polyethylene control samples.
This process fully crosslinks broken molecular chains, leaving virtually no free radicals to promote oxidation.
Proprietary electron beam process delivers 10Mrad dosage for greater crosslinking, resulting in superior long-term polyethylene wear performance compared to conventional polyethylene.,,,
Melt annealing vs. warm annealing virtually eliminates free radicals. Retrievals up to 10 years in vivo demonstrate no oxidation.,,
With millions of Longevity liners implanted since 1999, in a seven to ten year follow-up of 247 primary THA's using Zimmer Biomet Highly Crosslinked Liners, femoral head penetration did not increase over time after the first year of implantation using 241 primary THA's using standard polyethylene as the control.,
