Findings
Plain radiographs obtained in August
1986 showed changes of osteoarthritis in the medial compartment,
and a subchondral lucency (shown by arrow) and surrounding sclerosis,
findings suggestive of osteonecrosis. Bone
scintigraphy (left medial | anterior | left lateral)
performed one month later showed intense uptake of Tc-99m MDP in
the medial condyle of the left femur (shown by arrow). These findings are diagnostic
of spontaneous osteonecrosis of the knee.
