Simultaneous Imaging of Tissue Biochemistry and Metabolism Associated with Biomechanics in Patellofemoral Joint Osteoarthritis (PFJOA)

In this prospective study, we are aiming for a deeper understanding of the mechanics underlying bone and cartilage interactions (via simultaneous bilateral PET-MRI) and the mediation role of gait biomechanics and bone morphology for human subjects with isolated patellofemoral joint osteoarthritis (PFJ-OA). Our overall goal is to: (i) identify cross-sectional and longitudinal local patterns of cartilage and bone interactions unique to PFJOA, and (ii) determine the mediation effects of gait biomechanics and bone morphology on PFJOA progression. We are conducting a longitudinal cohort study investigating 100 people with isolated PFJOA. Simultaneous PET-MRI and gait biomechanics are being collected for all subjects at baseline and 2-year follow-up.
