The "reverse Segond" fracture: association with a tear of the posterior cruciate ligament and medial meniscus.
OBJECTIVE
We describe three patients who presented with radiographic findings of a fragment on the medial side of the tibial plateau of the knee that represented an avulsion of the deep portion of the medial collateral ligament. These findings were all associated with disruption of the posterior cruciate ligament and a peripheral medial meniscal tear-the so-called reverse Segond fracture.


CONCLUSIONS
Avulsion fracture at the tibial insertion of the deep component of the medial collateral ligament is a rare finding. When this type of injury is diagnosed, the radiologist should consider posterior cruciate ligament injury and peripheral medial meniscal tears as possible associated findings.
