Multidimensional management of a vascular injury following total knee arthroplasty: A rare case report.

Acute vascular injury during total knee arthroplasty (TKA) is an extremely rare complication, but one which can have devastating consequences threatening the limb and/or life of the patient if not diagnosed and managed at the earliest. The clinical presentation can vary from acute haemorrhage or ischemia in the peri operative period; to a delayed presentation of recurrent swelling and pain secondary to a geniculate or popliteal artery pseudoaneurysm. This is the first reported case of an acute inferolateral genicular artery haemorrhage following TKA and the associated medical complications. It was successfully managed with emergency percutaneous endovascular coiling and appropriate medical management. This case highlights that clinical suspicion, prompt diagnosis and urgent intervention with a multidisciplinary approach can help successfully manage a vascular insult.
