All fractures around the knee, particularly high-energy fractures (Schatzker types IV, V, and VI), can be associated with vascular injury. However, the medial plateau fracture behaves most like a knee dislocation, stretching or contusing the popliteal artery and the lateral soft tissues, including the peroneal nerve, at the time of fracture. The medial plateau requires greater force to fracture than the lateral plateau, and a fracture of the medial plateau should alert the examiner to possible significant soft-tissue injuries.
