case_images: TKA on the left side the previous day. The procedure was highly challenging due to the fixed varus contracture and complete imbalance of the capsular ligament apparatus, as well as severe synovitis (Fig 1).
case_images: Computed tomography image following the total knee arthroplasty (TKA) showing the occlusion of popliteal artery (PA).

case_images: The fibular artery (FA) and the posterior tibial artery (PTA) refilled through collaterals, whereas the anterior tibial artery (ATA) was occluded (Fig 2).
case_images: Intraoperative angiography. A, Complete thrombotic occlusion of the popliteal artery (PA) and anterior tibial artery (ATA) (red arrow), B and C, Refilling of the fibular artery (FA) (blue arrow) and the posterior tibial artery (PTA) (green arrow), whereas the ATA was occluded.

case_images: The foot was perfused mainly through the PTA (Fig 3).
case_images: Intraoperative angiography. A, Active bleeding from the popliteal artery (PA) (red arrow). B, Persistent bleeding after prolonged inflation of an angioplasty balloon (blue arrow). C, Control angiography after the implantation of the Viabahn (green arrow).

case_images: The follow-up angiography showed an active bleeding from the PA (Fig 4).
case_images: The completion angiography (A) and postoperative magnetic resonance angiography (B) both demonstrated patency of the popliteal artery (PA), fibular artery (FA), and posterior tibial artery (PTA) (blue arrow).

case_images: fig5
case_images: The FA and PTA, as well as the plantar arch, were patent, whereas the ATA was still occluded at the origin (Fig 5, A). Postoperative magnetic resonance angiography (Fig 5, B) confirmed satisfactory results with patency of the PA and the PTA.
