Superficial femoral artery pseudoaneurysm, compartment syndrome, and deep vein thrombosis after total knee arthroplasty

Vascular injuries after total knee arthroplasty are highly infrequent, especially in the femoral artery. These lesions can cause severe damage. Early diagnosis is important to prevent catastrophic complications (such as loss of limb) and to offer adequate treatment. This study reports a patient with femoral artery injury of unknown etiology after total knee arthroplasty. Progressive and insidious symptoms from deep vein thrombosis to compartment syndrome made management even more challenging, requiring amputation of the extremity.
