ASTM F3334: Standard Practice for Finite Element Analysis (FEA) of Metallic Orthopaedic Total Knee Tibial Components

Safety against fatigue fractures of tibial components of total knee replacements is typically determined according to ASTM F1800 or ISO 14879. ASTM F3334 is an excellent tool for worst-case assessment within a series of different implant sizes of the same implant design to reduce the physical test burden. Specific model verification is based on ASME V&V40 with special focus on the geometry and in-vivo loading of the tibial component.
