X3
X3 is a breakthrough in advanced bearing technology that results in a polyethylene bearing material that offers excellent wear characteristics while preserving mechanical strength.1-8 The result is a bearing surface option with properties great for both primary and revision applications.
X3 is sequentially crosslinked using three separate gamma radiation doses with an annealing step, polyethylene is heated below melting temperatures, following each irradiation. The sequential irradiation and annealing process provides a greater percentage of crosslinking while virtually eliminating free radicals.6,9,10 Finally, X3 is gas plasma sterilized to avoid additional radiation dosage during sterilization.
