Blood management in revision total knee arthroplasty.
Much attention has been focused on blood management issues in orthopaedic surgery in recent years, but blood management in patients having revision total knee arthroplasty is not well-established. Hematologic values and transfusion records of 100 patients (52 women, 48 men; mean age, 65 years) who had aseptic revision total knee arthroplasty at the authors' institution were evaluated retrospectively. Two- or three-component revisions comprised 66% of the procedures, and 58 patients participated in a preoperative autologous donation program. The mean preoperative hemoglobin level was 12.1 g/dL in the women and 14.1 g/dL in the men, but the men experienced a greater decrease in hemoglobin level (mean largest decrease, 4.2 g/dL versus 3.1 g/dL), possibly caused by the higher allogeneic transfusion rate in women (19.2%) versus men (4.2%). Patient age did not influence hemoglobin level or transfusion rates. Patients who participated in a preoperative autologous donation program had significantly higher hemoglobin levels before donation (14.4 g/dL versus 13.3 g/dL for patients who did not participate in a program) but comparable hemoglobin levels after predonation (12.9 g/dL). Patients with preoperative hemoglobin levels less than 13 g/dL were significantly more likely to have a transfusion. Symptom-based transfusion strategies and blood management approaches such as epoetin alfa that elevate preoperative hemoglobin level therefore may be beneficial in patients having revision total knee arthroplasty.
