Study of knee joint behaviour under load have a significant potential for Osteoarthritis (OA) diagnosis and monitoring. There are few reported studies on monitoring changes in knee cartilage under load using MRI. Reported process of validation of such loading device are in term repeatability and reproducibility. In this study, an approach is proposed to validate the loading-device using MRI data acquired in standing posture. OpenMRI(0.25T) was used to acquire data in various postures and results were compared with 3T-MRI data with and without load reliability and accuracy of various measurements such as bone-gap, cartilage-thickness and T2-values were evaluated.
