Confirmation of the Safety and Accuracy of Physical Examination in the Evaluation of Knee Dislocation for Injury of the Popliteal Artery: A Prospective Study

Abstract

This limited series suggests that the presence or absence of an injury of the popliteal artery after knee dislocation can be safely and reliably predicted, with a 94.3% positive predictive value and 100% negative predictive value. Arteriography appears to be unnecessary when physical examination is negative but may avert negative vascular exploration when physical examination is positive. This approach substantially reduces cost and resource use without adverse impact on the patient.
