6. CONCLUSION
In this study, frictional properties of OA articular cartilage during gait have been
assessed. Significant differences have been found between OA and healthy articular
cartilage. These differences are mainly due to the contribution of the effective friction
coefficient whereas the contribution of the normal contact force patterns was shown to
be less important but not negligible. Efforts have to be made in the future to determine
structural and mechanical properties representative of OA cartilage for each grade of the
disease since it may lead to its screening in its early phases.
