Due to risks associated with the transfusion of homologous blood, interest has grown in autotransfusion during and after surgical operations. This study examined the efficacy and safety of postoperative autotransfusion after total knee arthroplasty (TKA).A study group of 18 joints, 16 TKA patients who received autologous blood reinfusion was compared with a control group of 30 joints, 27 TKA patients who did not receive autologous blood reinfusion. All cases of study group were retransfused with washed blood cells 6 hours postoperatively, using the Collect First system (Haemonetics Corporation) and CellSaver Haemolite 2 (Haemonetics Corporation). Both groups were operated on in the same manner with the NexGen knee system (Zimmer).Results showed that the number of patients who needed homologous blood transfusions was reduced from 33.3% in the control group to 5.3% in the study group, the exception being a revision TKA case. There were no complications with autologous blood reinfusion.We conclude that postoperative retransfusion in TKA procedures can be used safely in clinical practice to decrease the need for homologous transfusion.
