Recurrent hemarthrosis after total knee arthroplasty is a rare complication. This usually occurs in osteoarthritis, but is relatively rare in rheumatoid arthritis. This is a report of recurrent hemarthrosis after total knee arthroplasty in a rheumatoid arthritis patient. An 85-year-old woman with rheumatoid arthritis had received total knee arthroplasty without acute complications. At 6 months after surgery, the first hemarthrosis occurred and an initial conservative treatment failed. Contrast computed tomography showed prominent synovial enhancement in the superior lateral suprapatellar pouch. Selective catheterization revealed an abnormal hyperemic blush supplied from the branches of the superior lateral genicular artery. After embolization with N-butyl-2-cyanoacrylate, abnormal staining of the synovium diminished and knee swelling and pain disappeared without complications. Selective embolization is favorable for successful treatment of recurrent hemarthrosis after total knee arthroplasty in patients with rheumatoid arthritis.
