E1 Antioxidant Infused Technology

Moving Beyond Simple Wear Reduction

E1 Antioxidant Infused Technology, the first vitamin E stabilized highly crosslinked polyethylene bearing material, is unlike any other polyethylene currently available for joint replacement.

• Biomet's E1 is a second generation material that has been shown in testing to provide high mechanical strength and oxidative stability.1

• E1 can provide an optimal combination of acetabular fixation and low wear1 when used with the Regenerex RingLoc®+ Modular Shell.

• The liners are available in 28mm, 32mm and 36mm inner diameters.


The key benefits of E1 Antioxidant Infused Technology include:

  • Higher levels of crosslinking for better wear performance
  • Greater strength than first generation remelted HXLPE 1-3
  • True oxidative protection without remelting 1


The E1 Process

Surpassing the limitations of first generation highly crosslinked polyethylene, E1 is truly a unique technology developed by Biomet's engineers and the research power of Massachusetts General Hospital.
 

  • Produced using a patent pending second-generation technology and proprietary process.
  • Isostatically compression molded polyethylene barstock, as used in clinically proven ArCom polyethylene, is processed below the melt temperature to maintain the strength of the crosslinked polyethylene.
  • Infused with vitamin E to stabilize free radicals and prevent oxidative degradation.


Testing has shown that E1 offers:

  • Ultra-low wear rates with large heads: 95 percent wear reduction when comparing 40mm E-Poly liners to 36mm ArCom liners and 99 percent wear reduction with smaller femoral heads when compared to already low ArComXL polyethylene.1
  • Fatigue strength greater than first generation re-melted HXLPE.1-3
  • Stronger than sequentially crosslinked and annealed materials after an environmental stress cracking (ESC) study.1


True oxidative protection without re-melting: no evidence of measurable oxidation.1
