911³ԹÏ

Overview

Longevity Crosslinked Polyethylene was developed to address the issue of wear in total hip arthroplasty. To help ensure optimal wear resistance, 911³ԹÏ employs a proprietary manufacturing process.

Procedures

  • 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

911³ԹÏ Longevity® Highly Crosslinked Polyethylene

System Features

Benefits

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 911³ԹÏ 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
