Therapeutic embolization for the treatment of recurrent hemarthrosis after total knee arthroplasty due to an arteriovenous fistula.

We describe the case of a 79-year-old woman who presented with recurrent hemarthrosis 8 years after primary total knee arthroplasty. An arteriovenous fistula of the superior lateral geniculate artery was diagnosed by arteriography after arthroscopy of the knee revealed multiple organized hematomata with minimal synovitis. The arteriovenous fistula was treated by percutaneous coil embolization and the symptoms resolved.
