Therapeutic Embolization for Spontaneous Recurrent Hemarthrosis of the Knee in the Elderly
Abstract
Without traumatic history, spontaneous hemarthrosis of the knee is a relatively rare condition, and there is no report of the diagnosis and treatments in Korea. In this case, magnetic resonance imaging and arthroscopic findings showed hemarthrosis and a lateral meniscus tear. Hemarthrosis of the patient remained after meniscus resection and coagulation; we then, found rupture of the lateral geniculate artery by computed tomography-angiography. We report on a case of successful treatment of spontaneous hemarthrosis with therapeutic embolization with a thorough review of the relevant literatures.
Figure 1
Plain radiograph showed asymmetric joint space narrowing (lateral side) of the left knee.
Figure 2
Magnetic resonance imaging showed hemarthrosis with increased suprapatellar fluid collection and air-fluid level and showed a bucket-handle type tear of the lateral meniscus with empty space in the lateral femorotibial joint space. (A) Sagittal plane. (B) Coronal plane.
Figure 3
(A) On arthroscopic finding, there was degenerative change in the lateral compartment and a bucket-handle tear was observed on the lateral meniscus and no abnormal finding of synovium. (B) Partial meniscectomy and coagulation was performed.
Figure 4
CT angiography showed contrast leakage on posterior and hemarthrosis of the left knee.
Figure 5
(A) Active bleeding and hypervascularity (arrow) were seen in intervention radiography. (B) After embolization, there was a significant reduction (arrow) in abnormal vascularity.
