This article presents an 80-year-old man with pseudoaneurysm of the inferolateral geniculate artery after total knee arthroplasty (TKA). The aim is to report this case and review possible preventive methods of pseudoaneurysm formation after TKA by investigating the relationship between knee arterial anatomy and the TKA procedure. Cadaveric evaluation demonstrates that the superomedial and inferomedial geniculate arteries are difficult to visualize. The anatomical position of the inferolateral artery makes it vulnerable to the surgical procedure during cutting of the tibia or while retracting soft tissue from the tibial edge, especially with minimal invasive surgery. In conclusion, careful subperiosteal release around the geniculate arteries is recommended. However, early recognition of pseudoaneurysm formation is even more essential than prevention.
本文报道了 1 例全膝关节置换术后（TKA）外侧下膝动脉假性动脉瘤的 80 岁男性患者。目的是通过研究膝关节动脉解剖与 TKA 手术之间的关系，报告该病例并探讨 TKA 后假性动脉瘤形成的可能预防方法。尸体评估表明，上内侧和下内侧膝动脉很难观察到。外侧下动脉的解剖位置使其在胫骨切割或从胫骨边缘牵拉软组织时容易受到手术的影响，尤其是微创手术。总之，建议在膝动脉周围进行仔细的骨膜下松解。然而，早期识别假性动脉瘤的形成甚至比预防更为重要。
