MRI findings of 45 cases with medial type osteoarthritis of the knee were reported. Various pathological findings which could not be detected by X-ray were revealed. Moreover, the MRI findings paralleled those of knee pain more than the X-ray findings did. There were also cases in which diffuse or wedge shaped signal changes were found deep in the femoral condyle. This suggests that the etiology for osteoarthritis of the knee should not discussed within the limited area of cartilage and subchondral bone.
