Genicular artery embolization for recurrent hemarthrosis: A case report.

A 44-year-old otherwise healthy male with a history of trauma and surgical interventions in his right knee presented to the emergency department with repeated hemarthrosis of the right knee. The patient underwent blood tests, X-rays, and magnetic resonance imaging of the knee. A computed tomography angiography revealed blushing of the synovium of the knee. The patient underwent successful embolization of the genicular artery branches. Hemarthrosis did not recur. The use of genicular artery embolization, in our case, not only successfully addressed recurrent hemarthrosis but also underscores its emerging role in comprehensive patient management. This minimally invasive approach, precisely targeting the vascular supply to the affected synovium, offers an effective alternative where conventional therapies may fall short. Beyond symptom relief, it holds promise for preventing hemarthrosis recurrence, a valuable addition to clinicians' interventions for challenging knee joint bleeding cases. Further investigation in larger cohorts and comparative studies may reveal its broader applicability and long-term efficacy, shaping treatment options for recurrent hemarthrosis.
