The object of this study is to evaluate whether low dose intravenous iron and erythropoietin (Epo) can decrease transfusion requirement after the bilateral TKRA.
Total knee replacement arthroplasty (TKRA) in severe osteoarthritis usually requires extensive soft tissue and bone dissection associated with substantial bleeding. Because TKRA is performed with a pneumatic tourniquet, intraoperative bleeding is not substantial, however, over 80% of the total blood loss occurs within the first 24 hour after the operation and the hidden blood loss is 50% of the total loss, making the true blood loss twice. Consequently, many patients can become anemic at early postoperative period and this anemic condition may lead to overall physical deterioration which include fatigue, dizziness, reduced exercise tolerance and delayed recovery.
Therefore, many patients frequently received the autologous or allogenic blood transfusion. In order to reduce the allogenic blood transfusion (ABT), various methods have been used, such as preoperative autologous blood donation (PABD), use of pharmacologic agents, iron or erythropoietin (Epo) and postoperative blood salvage. All of the above methods have been proved to reduce the ABT effectively6, without increase in cost.
Iron and Epo have been used widely in a variety of clinical situations instead of allogenic RBC transfusion. They also have been used for augmenting PABD or improving preoperative hemoglobin (Hb) level. However, there still remains a controversy about the efficacy of the method on the postoperative anemia. We think that these various results may be related with individual iron state of the patients and dose of drug or timing of drug application.
In this trial, iron and Epo are planned to be administered to the iron deficient non anemic patients during the operation and once again after surgery.

Anemia characterized by a decrease in the ratio of the weight of hemoglobin to the volume of the erythrocyte, i.e., the mean corpuscular hemoglobin concentration is less than normal. The individual cells contain less hemoglobin than they could have under optimal conditions. Hypochromic anemia may be caused by iron deficiency from a low iron intake, diminished iron absorption, or excessive iron loss. It can also be caused by infections or other diseases, therapeutic drugs, lead poisoning, and other conditions. (Stedman, 25th ed; from Miale, Laboratory Medicine: Hematology, 6th ed, p393)
Anemia characterized by decreased or absent iron stores, low serum iron concentration, low transferrin saturation, and low hemoglobin concentration or hematocrit value. The erythrocytes are hypochromic and microcytic and the iron binding capacity is increased.
An excessive accumulation of iron in the body due to a greater than normal absorption of iron from the gastrointestinal tract or from parenteral injection. This may arise from idiopathic hemochromatosis, excessive iron intake, chronic alcoholism, certain types of refractory anemia, or transfusional hemosiderosis. (From Churchill's Illustrated Medical Dictionary, 1989)
Iron or iron compounds used in foods or as food. Dietary iron is important in oxygen transport and the synthesis of the iron-porphyrin proteins hemoglobin, myoglobin, cytochromes, and cytochrome oxidase. Insufficient amounts of dietary iron can lead to iron-deficiency anemia.
Anemia characterized by the presence of erythroblasts containing excessive deposits of iron in the marrow.
