Pseudoaneurysm of the inferior medial geniculate artery following primary total knee arthroplasty: delayed presentation with recurrent haemorrhagic episodes.
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.
