UHMWPe Tibial Bearing Fatigue

Fatigue strength is also related to UHMWPe thickness for an all-UHMWPe tibial component of a total knee prosthesis. For any component with an overall thickness below 9 mm, a complete report of fatigue testing is recommended. FDA recommends testing five samples at various loads to develop an AF/N curve with at least one sample surviving 10 million cycles.
