Certain materials, such as Durasul, E-Poly HXLPE, and X3, can be found in both hip and knee products. The new product nomenclature, as well as the different techniques used in the irradiation, thermal processing, and sterilization of these new materials, may be confusing even to investigators who are accustomed to UHMWPE technology in joint replacement. 

The scientific data for E-Poly HXLPE is reviewed in Chapter 15. Hip and knee wear testing conducted by the inventors at MGH revealed over 90% reduction in wear in...
