title: Pseudoaneurysm of the inferior medial geniculate artery following primary total knee arthroplasty: delayed presentation with recurrent haemorrhagic episodes.
abstract: Arterial complications in primary total knee arthroplasty operation are rare. An 83 year old lady is described who presented with three recurrent haemorrhagic episodes eroding through the medial skin 4 weeks following primary total knee arthroplasty. A pseudoaneurysm of the geniculate artery should be suspected with recurrent or persistent haemarthrosis/haemorrhagic episodes. Early exploration, evacuation of the aneurysmal cavity and ligation of the feeding vessel should be undertaken if the false aneurysm is large in diameter.
