Most people have heard of a segond fracture (avulsion fracture of the lateral tibeal platuea) seen on knee xrays which is a marker for Anterior Cruciate Ligament and medial meniscus injuries. See Pearl https://umem.org/educational_pearls/1015/
However, there is also a Reverse Segond Fracture that is another benign appearing avulsion fracture of the medial tibeal plateau that is marker for significant injury to the Posterior Cruciate Ligament (PCL).
If a Segond or Reverse Segond Fracture is seen consider immobilzing the patients knee until they can follow up with Orthopedics and/or get an MRI to determine if additional injuries are present.
