ASTM F3141 – Standard Guide for Total Knee Replacement Loading Profiles
1.1 Motion path, load history and loading modalities all contribute to the wear, degradation and damage of implanted prosthetics. Simulating a variety of functional activities promises more realistic testing for wear and damage mode evaluation. Such activities are often called activities of daily living (ADLs). ADLs identified in the literature include walking, stair ascent and decent, sit-to-stand, stand-to-sit, squatting, kneeling, cross-legged sitting, into bath, out of bath, turning and cutting motions (1-7).2 Activities other than walking gait often involve an extended range of motion and higher imposed loading conditions which have the ability to cause damage and modes of failure other than normal wear (8-10).
