Early diagnosis and targeted intervention based on the pathogenesis of rapidly progressive osteoarthritis of the hip

Figure 1 Right hip joint with rapidly progressive osteoarthritis of the hip showing chondrolysis greater than 2 mm/year on a series of radiographs without femoral head destruction on computed tomography at 12 months after the onset. Magnetic resonance imaging at 6 months after the onset demonstrates inhomogeneous high intensity on the short τ inversion recovery sequence image, including the superolateral portion of the femoral head. CT: Computed tomography; MRI: Magnetic resonance imaging.
