Fig. 1 Isolated patello-femoral structural damage. A. Axial proton density-weighted image shows fissure-like full-thickness defect at the lateral patellar facet (arrow). No additional structural damage was observed. B. Diffuse and extensive but still isolated full-thickness cartilage damage in the medial patellar facet is shown in this axial proton-density-weighted image (arrows).

Fig. 2 Isolated early tibiofemoral structural damage. A. Coronal STIR image shows bone marrow lesion at the medial tibial plateau (short white arrows) with adjacent superficial focal cartilage lesion (long white arrow). In addition there is a small bone marrow lesion at the medial femur (gray arrow). B. Another example shows a superficial cartilage defect at the central medial femur (arrow).
