    AbstractHaemarthrosis is an uncommon complication of anticoagulation therapy. Tranexamic acid (TXA) has a high clinical value for the treatment of bleeding due to fibrinolysis. We describe a case of a 61-year-old woman with a mechanical heart valve who presented with warfarin-related recurrent haemarthrosis of her right knee, which recurred after transarterial embolisation. Intra-articular injection of TXA led to a cessation of haemarthrosis without any adverse event for 1 year. Intra-articular injection of TXA may be an effective treatment for warfarin-related haemarthrosis. 2015 BMJ Publishing Group Ltd.
