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.

Please refer to the package inserts for complete product information, including contraindications, warnings, precautions, and adverse effects.
Longevity implants are sterilized with Ethylene Oxide Gas and carry the symbol on the labeling. These devices remain sterile as long as the package integrity has not been violated. Inspect each package prior to use and do not use the component if any seal or cavity is damaged or breached or if the expiration date has been exceeded. Once opened, the component must be used or discarded.
Resterilization of this device is specifically not recommended.
Crosslinking has been shown to reduce the wear rate of polyethylene
by up to 89% in laboratory studies.1 Clinical experience
with highly crosslinked polyethylenes has also demonstrated a
substantial reduction in the rate of wear.2,3 This
remarkable process creates a three-dimensional structure that is more
resistant to abrasion.4,5
Longevity Highly 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 based in part on patents licensed from Massachusetts General Hospital and the Massachusetts Institute of Technology. Using high-dose electron-beam radiation, this process fully crosslinks broken molecular polyethylene chains, leaving virtually no free radicals to promote oxidation.
The process produces a 10-fold wear rate reduction—an average 89% reduction of debris generated—compared to standard polyethylene control samples.1 The material also meets all of the mechanical property requirements of the ASTM and ISO standards. Longevity Crosslinked Polyethylene is available with the Continuum ® Acetabular System, Trabecular Metal™ Modular Acetabular System, and Trilogy ® Acetabular System, which is based on the long Zimmer tradition of clinical success with the Harris-Galante™ and HGP II porous cups.
