Abstract
Chronic recurrent hemarthrosis, defined as repeated intra-articular hemorrhage, can
lead to a disabling arthropathy. We herein report on a 26-year-old patient presenting
with recurrent, postoperative, serious knee hemarthrosis refractory to conventional
treatment, including systemic and intra-articular steroid injections as well as chemical
synovectomy with osmic acid. The patient was finally treated with a twice performed
knee radiosynovectomy with yttrium-90 and showed an extraordinary good clinical outcome
with a symptom-free period of 4 years. In cases of refractory hemarthrosis, radiosynovectomy
should have a place in the therapeutic armamentarium of the treating physician, as
a minimally invasive, safe, and efficient therapeutic tool.
