↵* Among participants with paired knee radiographs = history of injury, fracture, or surgery of the knee; among participants with paired hip radiographs = history of injury, fracture, surgery, or congenital problem of the hip. rOA: radiographic OA; among participants with paired knee radiographs refers to knee joint, among participants with paired hip radiographs refers to hip joint. T0: baseline assessment. T1: followup assessment. BMI: body mass index.
