Embolization of the Geniculate Arteries Is an Effective Treatment of Recurrent Hemarthrosis Following Total Knee Arthroplasty That Can Be Safely Repeated

Embolization of the geniculate arteries in our study was a safe and effective treatment of recurrent spontaneous hemarthrosis following TKA. Although we have performed a substantial number of reinterventions, results of this study show that this procedure can be safely repeated without adverse events. Our results indicate that embolization could possibly be the treatment of choice when conservative measures fail and can be repeated in the event of recurrent or persistent symptoms.
