Some cases of idiopathic osteonecrosis of the medial femoral condyle treated conservatively get better, whereas others show no remarkable change or become worse. Fourteen cases of idiopathic osteonecrosis of the medial femoral condyle that received long-term conservative treatment at our clinic were evaluated. We investigated the association between age and size of osteonecrosis at the onset, FTA, body weight and prognosis.<BR>The average age at the onset was 68 years with a range of 55 to 91. The average period of followup was 3.2 years with the range of 1 year to 7 years. Of the fourteen cases, three had improved according to roentgenological findings, four were unchanged and seven had gotten worse. The prognosis of this disease did not correlate with the age at the onset, but did correlate with the size of osteonecrosis and FTA. Moreover, the tendency to have a poor prognosis was shown with the cases who were obese.
