The new generation of highly cross-linked polyethylene blended with vitamin E to enhance wear resistance without compromising oxidative stability and mechanical properties.
- Mitigate Oxidation Risk
Testing on the U2™ Knee with E-XPE™Insert shows blended Vitamin E helps to prevent in vivo oxidation and subsequent degradation.1
- Proven Wear Resistance
Accelerated aging tests illustrate that the E-XPE™ insert and liner exhibited a 60% and 75% reduction, respectively, in gravimetric wear.
- Unparalleled Mechanical Properties
Mechanical testing demonstrates that the U2™ Knee with E-XPE™ insert maintains and may even improve strength.2
