Longevity Crosslinked Polyethylene was developed to address the issue of wear in total hip arthroplasty. To help ensure optimal wear resistance, Zimmer Biomet employs a proprietary manufacturing process.


  • Hip Technologies

Clinical experience with highly crosslinked polyethylenes has 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

Reduced Wear


Crosslinking reduced wear rate of polyethylene in laboratory studies.1

Reduction of Debris


Compared to standard polyethylene control samples.1


Highly Resistant to Wear6-8

  • Proprietary electron beam process delivers 10Mrad dosage for greater crosslinking, resulting in superior long-term polyethylene wear performance compared to conventional polyethylene.

Highly resistant to aging9-11

  • Melt annealing vs. warm annealing virtually eliminates free radicals. Retrievals up to 10 years in vivo demonstrate no oxidation. 

Functions as Intended12

  • 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 control4
