Abstract
An 88-year-old woman complained of pain in the medial part of her knee for 5 weeks. Plain radiography was normal. Clinical and scintigraphic findings were suggestive of spontaneous osteonecrosis of the medial femoral condyle. Magnetic resonance imaging showed a stress fracture of the medial femoral condyle. In 3 weeks pain had disappeared, confirming this diagnosis.
