High Demand Hip Wear Test of Hard-on-Hard Articulations
This guide suggests possible high demand test features to be considered in evaluating hard-on-hard articulations. A standard hip wear test according to ISO 14242 is performed prior to high demand testing. Possible high demand tests include: higher acetabular liner/shell angle, the addition of 3rd body particles, higher loading parameters, stop-dwell-start programmed into waveform, and micro-separation of articulating surfaces.
