Criteria

Inclusion Criteria:

• Adult patients who plan to undergo simultaneous primary total knee arthroplasty on bilateral knee joint with a diagnosis of osteoarthritis or aseptic bone necrosis, but not of rheumatoid arthritis;

• All patients who have normal preoperative platelet count, normal prothrombin time, normal partial thromboplastin time, and normal international normalized ratio;

• The use of only balanced electrolyte solutions and/or albumin for plasma volume restitution

Exclusion Criteria:

• Preoperative use of anticoagulant therapy within five days before surgery, fibrinolytic disorders requiring intraoperative antifibrinolytic treatment, coagulopathy (as identified by a preoperative platelet count of <150,000/mm3, an international normalized ratio of >1.4, or a prolonged partial thromboplastin time [>1.4 times normal]).
