Purpose: Alterations in bone shape are not only associated with the presence of radiographic OA, they are predictive of tibiofemoral OA onset and have even been proposed as a biomarker for tibiofemoral OA progression. Such biomarkers for early OA detection and progression are essential in the developing successful and early OA interventions. There...
