Dear Biomech-l subscribers;
I am writing to ask for suggested values for the mechanical properties of
the cartilages and meniscus of the medial compartment of the knee. I am
interested in forming a Finite Element model for preliminary studies and
am curious if an elastic model and respective material properties are
sufficient to describe a single solution in time. The purpose of the
model is not to demonstrate time-dependent behavior of the tissue's
stress states, only to demonstrate changes in cartilage stress levels
with joint geometry changes. Due to the fact only a relative comparison
is sought, I was hoping an elastic (i.e. non-biphasic) model would be
sufficient to represent the contact behavior at some arbitrary instant in
time (with the understanding that the results would normally demonstrate
a time dependence).
Do you believe an elastic model can produce useful comparisons? If so,
can you recommend 'effective' elastic moduli (or non-linear relations)
and poisson ratios for the medial articular cartilages of the knee and
the medial meniscus.
Thank you very much for any information you can provide,
