Abstract
Popliteal artery aneurysm is a rare but dangerous complication that can occur after total knee arthroplasty (TKA). Early identification and prompt treatment are necessary for a favorable outcome. We can observe a shift toward endoscopic surgical procedures, replacing open surgical procedures to address this treacherous complication. We report a case of missed popliteal artery pseudoaneurysm following an uneventful bilateral TKA, which was initially treated with evacuation of hematoma and compression bandaging by the primary surgeon. Upon presentation, the patient was treated with embolization and antegrade endovascular stenting. The patient was maintaining a good functional outcome until seven years of surgery, following which the patient developed claudication of the same limb. He was diagnosed with in-stent restenosis (ISR) of the popliteal covered stent without chronic limb-threatening ischemia (CLTI) and was managed with oral medications. Patient is comfortable with the oral medications at his eight-year follow-up.
