Presentation
Road traffic accident 1 week back. Left knee injury.
Patient Data
There is a fracture of the fibular head. There is no dislocation/ bone lesion. The femorotibial compartment joint space is maintained in a non-stress view. However, stress views show abnormal joint space opening.
Case Discussion
A patient presented with knee injury. Non-stress radiographs show an avulsion fracture of the fibular head. There is a significant opening of the medial and lateral compartments of the femorotibial joint in valgus and varus stress views respectively.
Findings favor multi-ligament injury/laxity.
Later MRI was done which revealed a complete tear of the anterior cruciate ligament, intra-substance tear of the posterior cruciate ligament, grade II injury of the medial collateral ligament, and lateral collateral ligament avulsion.
