Sagittal, axial, and coronal T2WI FS MR images show marrow oedema in the anterior aspect of the proximal tibial epiphysis. The marrow oedema extends down into the tibial tubercle. There is fluid interposed between the proximal tibia and the distal patellar tendon, denoting deep infrapatellar bursitis. Mild soft tissue swelling is seen anterior to the distal patellar tendon.
