We present a 69-year-old male with osteoarthritis of a varus mechanically aligned left knee that developed delayed arterial thrombosis after primary total knee arthroplasty (TKA) requiring stenting and subsequent trans-metatarsal amputation. This case is unique since initial presentation involved neurologic instead of ischemic changes. We also performed a literature review of arterial injuries in primary TKA. This case highlights the importance of maintaining a high clinical suspicion for vascular insult in patients undergoing correction of varus malalignment with initial complaints of neurologic dysfunction.

初发全膝关节置换术在足内翻膝关节后出现足底延迟性动脉闭塞：一例病例并文献复习

我们介绍了一位69岁的男性，其机械性对准左膝内翻的骨关节炎，在原发性全膝关节置换术（TKA）需要支架置入术和随后的经met骨截肢后发展为延迟性动脉血栓形成。这种情况是独特的，因为最初的表现涉及神经系统而非缺血性改变。我们还对原发性TKA的动脉损伤进行了文献综述。该病例凸显了在接受内镜功能不全矫正并最初出现神经功能障碍的患者中，对血管损伤保持高度临床怀疑的重要性。
