Preserving Strength
The structural strength of X3 Advanced Bearing Technology allows it to be applied to knee applications where abrasive, adhesive, and fatigue wear may be present due to a more cyclical motion pattern.1
Maintenance of mechanical strength allows X3 technology to be applied to tibial bearings that are subject to greater shear stresses such as posteriorly stabilized tibial inserts. These shear loads on the PS post create a moment arm to the locking mechanism, potentially increasing the stress on the polyethylene in the posterior region of the mechanism.2,3
X3 Advanced Bearing Technology maintains mechanical properties after accelerated oxidative age laboratory testing. No statistical difference was found for tensile-yield strength, ultimate tensile strength, and elongation.4,5
