A father and son travelling in their car were involved in a collision with another vehicle. Subsequently, both were found to have what were thought to be long-standing developmental bipartite patellae. However, subsequent investigations and the patients' progress cast doubt on this diagnosis and suggested that the lesions were fractures.
