Bilateral knee and right ankle osteonecrosis in an adolescent girl with acute lymphoblastic leukemia.
Although rare, avascular necrosis of bone is a serious and incapacitating complication seen in children with acute lymphoblastic leukemia receiving high dose steroids. Here we present a 16 year-old girl who developed bilateral knee and right ankle avascular osteonecrosis one year after intensive chemotherapy for medium risk acute lymphoblastic leukemia. Indirect curettage of necrotic tissue and bone grafting were performed for both knees whereas conservative measures had been sufficient for the ankle. Early recognition of this condition is important in prevention of disabling sequela in skeletal system.
