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.
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 (non-surgical, 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.
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.
Core tip: 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 present herein a rare case of recurrent hemarthrosis which occurred 14 mo after total knee arthroplasty. The patient underwent traditional investigations (ultrasound, aspiration, and arthroscopy) and managements (non-surgical, arthroscopy and open exploration), and the clinical effects of these interventions were analyzed separately. Clinical evidence indicated that the cause of recurrent hemarthrosis in this case was rupture of a pseudoaneurysm of the medial superior genicular artery.
