PCL injury is usually due to hyperextension of the knee. This is a typical case with only partial disruption to ligament fibres (unlike the ACL that usually ruptures completely) as well as an anterior impaction pattern of bone marrow oedema (microtrabecular fracture) ie the medial femoral condyle has been impacted onto the anterior aspect of the medial tibial plateau.
