very high strain rates (Edelsten et al ., 2010), which was unlikely to be asso-
ciated with the uid-driven viscoelasticity. The relative importance of the
inherent viscoelasticity of the PG matrix is not clear at the moment, as com-
pared to that of collagen viscoelasticity.
7.4 Applications and challenges
It is neither within our scope nor possible to cover the full range of applica-
tions for computational modelling of articular cartilage. A few examples are
given here in the hope of encouraging further reading and inspiring new
applications in orthopaedic biomechanics.
