Posterior cruciate ligament (PCL) avulsion fractures are a type of avulsion fracture of the knee that represent the most common isolated PCL lesion. This typically involves the separation of the posterior tibial insertion of the PCL to variable degrees.
These injuries are commonly seen in motorcycle or car accidents (dashboard injuries) in which posteriorization forces occur against the tibia in a flexed knee, individuals who jump and land on a plantarflexed foot whilst the knee is in flexion, often in the context of sport.
• type I: non-displaced
• type II: upward displacement of the posterior aspect of the avulsed tibial bone fragment
• type III: totally displaced avulsed bone fragment
