The radiographs are normal. Initial management is often provided by primary care and emergency clinicians, who must therefore be familiar with these injuries. Both the broken bone and any soft-tissue injuries must be treated together. Treatment is urgent to avoid complication of osteonecrosis, nonunion, and premature physeal closure. (OBQ09.189) Treatment is usually closed reduction and casting in extension with a varus mold. Abstract. Diagnosis can be confirmed with plain radiographs of the knee.
