Transfusion in unilateral total knee arthroplasty.

Blood transfusion requirements were analyzed in 102 total knee arthroplasties in 92 patients. All components were cemented, and no postoperative drainage was used. Six patients received transfusions; two of these patients received transfusions for symptoms and four received transfusions prophylactically. These findings do not support the routine practice of preoperative autologous blood donation.
