title: Osteochondritis dissecans development after bone contusion of the knee in the skeletally immature: a case series.
abstract: Osteochondritis dissecans (OCD) is thought to be an acquired osteochondral disorder, and its aetiology may be multifactorial. Trauma, both acute and repetitive events, has previously been proposed as a potential cause for OCD development. We present two cases of skeletally immature boys who developed a symptomatic OCD lesion following a femoral condyle bone contusion. These cases suggest that an acute traumatic event may lead to the development of OCD of the knee.
