Patients were predominantly male (n = 16, 61.5%) with a mean age of 45.1 \u00b1 13.3 years. All patients had a blunt injury mechanism resulting in mostly closed (n = 25, 92.6%), bicondylar (n = 22, 81.5%) tibial plateau fractures. CTA demonstrated nonatherosclerosis vascular abnormalities in 3 patients (11.5%). Two had disrupted flow in the popliteal artery, and 1 had disrupted flow in the anterior tibial artery. No patient required vascular intervention. Atherosclerosis was appreciated in 6 (26.9%) patients. One of 3 patients (33%) with nonatherosclerosis vascular abnormalities had wound complications. Four of 24 patients (16.7%) without nonatherosclerosis vascular abnormalities had wound complications. There was no significant correlation between nonatherosclerosis vascular abnormalities and wound complications (abnormality present: 33.3% wound complication rate vs. no abnormality: 16.7%,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.47).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS:<\/jats:title>\n                    <jats:p>Non atherosclerotic vascular abnormalities on CTA were found in approximately a 10th of high-energy tibial plateau fractures.
