Few have compared short-term outcomes following knee dislocations with or without concomitant popliteal artery disruption (PAD).
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%).
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).
High suspicion index should be maintained for concomitant vascular injuries following knee dislocations.
很少有人比较过伴有或不伴有腘动脉损伤（PAD）的膝关节脱位后的短期预后。
利用全国住院患者样本，确定了2005年至2013年因膝关节脱位入院的2175例患者（伴有PAD：n = 210/9.7%；不伴有：n = 1965/90.3%）。
伴有PAD的患者更年轻，男性、黑人和西班牙裔比例更高，且参加医疗补助计划（所有p≤0.013）。PAD与住院时间延长几率高11.0倍（95%CI，6.6 - 18.4）以及发生任何并发症几率高2.8倍（95%CI，2.03 - 3.92）相关。女性是住院时间延长的保护因素（OR = 0.65；95%CI，0.48 - 0.88）。
对于膝关节脱位后伴发的血管损伤应保持高度怀疑指数。
