摘　　要：BACKGROUND Recurrent hemarthrosis is a rare complication of total knee arthroplasty,and only a few cases have been reported;hence,it is hard to establish comprehensive diagnosis and treatment guidelines.We here report a case of recurrent hemarthrosis after total knee arthroplasty,and briefly review the literature.CASE SUMMARY A 50-year-old man,with a history of hypertension,presented to the Orthopedic Department of our hospital for non-traumatic acute left knee pain and swelling associated with a warmth sensation 14 mo after total knee arthroplasty.Investigations(ultrasound,aspiration,and arthroscopy)and managements(nonsurgical,arthroscopy and open exploration)were performed,and the clinical effects of these interventions were analyzed separately.Clinical evidence indicates that the cause of this case was rupture of a pseudoaneurysm of the medial superior genicular artery.CONCLUSION The present case indicated that angiography is essential in cases of hemarthrosis after TKA;arthroscopy may not always be adequate as it may not provide a clear view;and traditional open exploration is still effective and sometimes necessary.
