Hyperextension injury

Momentum carries the person forward, but their foot cannot follow, leading to knee hyperextension.

Hyperextension and the PCL

Hyperextension is a classical modus of injury of the posterior cruciate ligament (PCL).

There may also be damage to other structures of the posterolateral corner.

• Quote from peer-reviewed paper:

  "...Despite considerable attention in the clinical orthopaedic literature (nearly 400 articles published in the last decade), a standardized algorithm for the diagnosis and treatment of the PLC is still lacking, and much controversy remains...."
