Knee Dislocations - Dr. Gibbs

5/29/2014

Picture
Basics
  • Can result from high OR low velocity injuries.
  • ~30% of high-velocity dislocations have associated life-threatening injuries.
  • 60% have associated fractures. 40% have multiple fractures.
  • 15-30% have vascular injury!!

The Literature is Consistent
  • An ABnormal exam mandates angiography!
  • A NORMAL exam is associated with either no injury or inconsequential vascular injury.
  • An Ankle-Brachial-Index (ABI) < 0.9 is indicative of vascular injury.
  • An ABI of > 0.9 is highly predictive of lack of significant vascular injury.

Imaging?
  • Duplex Doppler has reported sensitivity of 95%, but is operator dependent and can miss intimal tears.
  • CT Angiography is highly sensitive for vascular injury, but do a good exam and check ABIs first!
