Avulsion fracture of the anteromedial bundle of the anterior cruciate ligament.
The avulsion fracture of the tibial attachment site of the anterior cruciate ligament is relatively rare among adults. Although partial avulsion fracture of this site is very rare, complex forces exerted on the knee joint could produce this type of fracture. We report on an adult patient with an avulsion fracture of the attachment site of anteromedial bundle of the anterior cruciate ligament associated with injuries of lateral and medial collateral ligament and fibular fracture. We speculate varus stress in a flexed knee coupled with rotation between the femur and tibia caused this type of injury.
