T1 lower case Greek rho /T2 MRI quantification can be used to detect cartilage early degeneration after ACL injury and reconstruction. Recently, bone shape features have been proposed as biomarkers for predicting OA progression. However, the potential role the shape in the development of post-traumatic OA is unknown. In the present study, Statistical Shape Modeling is applied to explore the relationship between knee bone shape and the progression of cartilage T1 lower case Greek rho /T2 1 year after ACL reconstruction. The results of this study suggest that specific aspects of the bone shape may predict the progression of T1 lower case Greek rho /T2 6 month and 1 year after ACL reconstruction.
