“… 1 , 3 Analysis of the contact mechanics is therefore limited to instantaneous behaviour, and although comparisons of contact mechanics between different geometric cases have merit for ranking the effect of geometric features, magnitudes are not representative of the in vivo case. Future studies using the parameterised hip model could therefore incorporate more sophisticated materials for the cartilage, such as biphasic properties, 1 , 3 , 10 , 33 and more parameters to represent the shape and thickness of the cartilage, 5 , 7 , 25 in order to achieve results more in line with the in vitro and in vivo performance.…”
