title: [Traumatic separation of a type I patella bipartite in a sportsman].
abstract: This is a case report of a 44-year-old sportsman who experi-enced acute onset of strong pain and loss of ability to extend his right knee during a game of beach volley. X-ray imaging showed a patella in two parts with rounded edges and with a diastasis of more than 2 cm. Intra-operatively atrophic fibrocartilage was found on both parts of the patella. Asymptomatic patella bi-partite was found on X-ray imaging of the patient's left knee, and he was diagnosed to have traumatic separation of a type I patella bipartite. The diagnosis was confirmed by surgical and radiological findings.
