3. Fig. 2
Representative 3 T Knee MRI images illustrating the most prominent knee pathologies observed in patients with IL-ROA. Image to the left (sag 3D DESS sequence): shows a severe cartilage lesion involving the lateral posterior femoral condyle. Middle image (sag Fat suppressed TSE sequence): depicts a severe lateral femoral bone marrow lesion. Image to the right (Sag Fat suppressed TSE): shows a lateral meniscal tear involving the anterior and posterior horn.

4. Fig. 3
Representative cartilage T2 color maps of the lateral tibia shown for a subject with IL-ROA (on the left), a subject with IM-ROA (middle) and a control subject (on the right). Cartilage T2 color maps were overlaid on the first-echo images of the multislice multiecho (MSME) sequence. T2 values are displayed on a voxel by voxel basis. Blue voxels indicate low cartilage T2 values, red voxels signify high cartilage T2 values. Subjects with IL-ROA showed significantly higher mean T2 values than subjects with IM-ROA or controls (P < 0.001).
