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.
