The AP and lateral views of the right knee show no focal soft tissue swelling or joint effusion. No acute bony injury is seen. However, there is apparent subchondral lucency in the central weight-bearing portion of the medial femoral condyle with faint surrounding sclerosis, suggestive of spontaneous osteonecrosis of the knee. Prominent vascular calcification is also noted. Further clinical correlation and possibly an MR examination are suggested if clinically indicated.
