Severe cartilage loss in the lateral tibiofemoral and patellofemoral compartments. A. Posteroanterior radiograph of the right knee shows diffuse medial and lateral tibiofemoral osteophytosis and lateral joint space narrowing, which classify the knee as Kellgren-Lawrence grade 3. B. Sagittal contrast-enhanced T1-weighted magnetic resonance imaging (MRI) shows marked synovitis at the dorsal surface of Hoffa’s fat pad (large arrow). In addition there is severe synovitis at the suprapatellar recess (arrowhead) and posteriorly adjacent to a femoral osteophyte and perimensical (thin arrows). C. Axial contrast-enhanced T1-weighted MRI shows diffuse severe synovial thickening at the medial and lateral patellar recesses (arrows). There is also diffuse full thickness cartilage loss in the lateral patellofemoral joint with adjacent bone marrow lesions (arrowheads).
