title: Osteochondral fractures of the lateral femoral condyle: a result of indirect violence to the knee.
abstract: Twenty patients with an average age of eighteen and a half years sustained osteochondral fractures of the lateral femoral condyle as the result of a sudden twist and valgus strain to the straight or almost straight knee. All the patients felt sudden pain at the moment of injury, all had a haemarthrosis, and yet the fracture escaped early diagnosis in one-third of the cases. Internal fixation of the fragment with early mobilisation is recommended if the diagnosis is made within two weeks of injury, and excision of the fragment if it is only later identified.
