Arterial complications in primary total knee arthroplasty operation are rare. An 83 year old lady is described who presented with three recurrent haemorrhagic episodes eroding through the medial skin 4 weeks following primary total knee arthroplasty. A pseudoaneurysm of the geniculate artery should be suspected with recurrent or persistent haemarthrosis/haemorrhagic episodes. Early exploration, evacuation of the aneurysmal cavity and ligation of the feeding vessel should be undertaken if the false aneurysm is large in diameter.
初次全膝关节置换手术中的动脉并发症较为罕见。本文描述了一位83岁的女性患者，她在初次全膝关节置换术后4周出现了3次反复的出血性发作，血液侵蚀内侧皮肤。如果出现反复或持续的关节积血/出血性发作，应怀疑是膝部动脉假性动脉瘤。如果假性动脉瘤直径较大，应尽早进行探查、清除动脉瘤腔并结扎供血血管。
