Longevity Crosslinked Polyethylene was developed to address the issue of wear in total hip arthroplasty. To help ensure optimal wear resistance, Zimmer employs a proprietary process.
Removable Longevity Liners are available in neutral, elevated, oblique, and 7-mm offset. This offers a range of options to assist the surgeon in optimizing femoral head coverage and restoring proper hip kinematics.
Using high-dose electron-beam radiation, this process fully crosslinks broken molecular chains, leaving virtually no free radicals to promote oxidation.
This process creates a three-dimensional structure that is more resistant to abrasion and process a 10-fold wear rate reduction compared to standard polyethylene control samples.1,2 Extensive hip-simulator wear testing has demonstrated the benefits of crosslinking with Longevity Polyethylene.
Longevity Crosslinked Polyethylene is available with the Trilogy® Acetabular System.
Works as Predicted
- 10+ years of clinical experience
- More than 1 million Zimmer Highly Crosslinked Polyethylene Liners implanted3
- In a seven to ten year follow-up of 247 primary THA's using Zimmer 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 control4
- Independent testing has shown that the in vitro wear rate of Zimmer's Highly Crosslinked Polyethylene was near zero and lower than that of its competitors
