OBJECTIVE: Few have compared short-term outcomes following knee dislocations with or without concomitant popliteal artery disruption (PAD). METHODS: The Nationwide Inpatient Sample was used to identify 2175 patients admitted for knee dislocation from 2005 to 2013 (concomitant PAD: n = 210/9.7%; without: n = 1965/90.3%). RESULTS: Patients with PAD were younger, more often male, Black and Hispanic, and with Medicaid (all p ≤ 0.013). PADs were associated with 11.0-times higher odds of increased LOS (95%CI, 6.6-18.4) and 2.8-times higher odds of experiencing any complication (95%CI, 2.03-3.92). Female sex was a protective factor against increased LOS, (OR = 0.65; 95%CI, 0.48-0.88). CONCLUSION: High suspicion index should be maintained for concomitant vascular injuries following knee dislocations.
