FIG1
The MRI confirmed the diagnostic suspicion of an osteochondral lesion measuring approximately 13 x 13 x 4 mm of greater anteroposterior, transversal, and thickness axes, on the weight-bearing surface of the internal femoral condyle, without signs of instability, without apparently detached bone fragments, associated with marked bone medullary edema of the internal femoral condyle, and of a very slight degree in the medial peripheral aspect of the homolateral tibial plate (Figures 1, 2).

FIG3
The MRI showed discrete evolution of the lesion with loss of complete cartilaginous thickness of the bearing surface of the internal femoral condyle with associated slight subchondral collapse, in the context of an osteochondral lesion due to grade IV chondropathy with subchondral fracture, probably due to insufficiency and without a detached osteochondral fragment or signs of instability (Figures 3, 4).
