We retrospectively studied blood loss in 75 cases of total knee arthroplasty for osteoarthritis. Subjects were divided into two groups; Group A, tourniquet was released intraoperatively and hemostasis achieved with electrocoagulation. Group B; tourniquet remained inflated throughout the operative procedure and was released after a compressive dressing. The amount of intraoperative blood loss and total blood loss in group A were significantly larger than those in group B.We performed autologous transfusion with administration of recombinant erythropoietin to patients treated with total knee arthroplasty since 1990. Before performing this procedure, 42.9% of our patients required transfusion with homologous blood. We can avoid homologous transfusion in 94.7% of our patients by using autologous transfusion.
