Podcast 527: Knee Dislocations

Podcast 527: Knee Dislocations

Contributor: Erik Verzemnieks, MD

Educational Pearls:

  • Knee dislocations are most common in high energy trauma, such as a motor vehicle accident
  • The knee may appear grossly normal on initial inspection since dislocations can spontaneously reduce - Look for such findings as hemarthrosis, instability, or ecchymosis, as clues to an occult dislocation.
  • Knee dislocations are often associated with damage to the popliteal artery that runs behind the knee.
  • Assess for pulse deficit on exam. If you are concerned - use the ankle-brachial index (normal >0.9). If the ABI is abnormal, evaluate with CT angiogram and a vascular surgery consult.
