Use of warfarin after TKA is rarely associated with hemarthrosis. With a benign wound 3 weeks after surgery, sepsis is unlikely. ESR and CRP level may both be elevated in the postoperative period. Deep vein thrombosis is normally associated with calf pain and is usually seen within 1 week of surgery. Because the patient is comfortable bearing weight and walking, fracture and rupture of the patellar tendon are unlikely. Given the scenario of knee pain and supratherapeutic anticoagulation, the most likely cause is hemarthrosis.
