AVULSION OF THE PATELLAR LIGAMENT WITH COMBINED FRACTURE LUXATION OF THE PROXIMAL TIBIAL EPIPHYSIS - CASE-REPORT AND REVIEW OF THE LITERATURE

Disruption of the extensor mechanism of the knee joint at the insertio n site of the patellar tendon into bone is a somewhat common injury. A vulsion of the patellar ligament associated with fractures of the prox imal tibial epiphysis is an extremely rare injury, Only three cases ha ve been published in association with avulsion fracture of the tibial tubercle. We are reporting a case that has previously not been reporte d to our knowledge: an avulsion of the ligament in a closed fracture o f the proximal tibial epiphysis with integrity of the tibial tubercle, We propose a three-type classification of an avulsion patellar ligame nt injury.
