Superior Medial Geniculate Artery Pseudoaneurysm After Primary Total Knee Arthroplasty

Julien, Terrill P. et al.

Vascular complications after total knee arthroplasty are rare. To date, there are 7 reported cases of pseudoaneurysms affecting the popliteal artery and 6 cases affecting one of the geniculate arteries. We present a case of a geniculate artery pseudoaneurysm that shared symptoms of a deep venous thrombosis on physical examination of a patient who underwent primary total knee arthroplasty. To date, there are no reports in American literature of pseudoaneurysms affecting the superior medial geniculate artery after primary total knee arthroplasty. After a vascular workup including computed tomographic angiography, surgical management included evacuation of the pseudoaneurysm and ligation of the feeding artery. The patient went on to successful recovery.
