Standing weight-bearing MR images of the knee joint in full extension and at various flexion angles (~15°, 30°) were acquired using 2D and 3D sequences on a newly developed open 0.25T extremity MRI system. 3D FLASH images were used to calculate measures of patella positioning used in previous clinical investigations as well as to produce MRI-based 3D bone models. The use of MRI and 3D modeling for topographical analyses of the bones and soft-tissues of the knee joint have the potential to provide more detailed assessment of pathoanatomical conditions involving structures such as the patella tendon and the menisci.
