Summary

Computer navigation reduces blood loss in TKR with reduced incidence of blood transfusion and this may be clinically relevant to transfusion requirements.

Abstract

If Computer Navigation reduces the incidence of blood transfusion in TKR ?

Computer navigated total knee arthroplasty (TKA) has several proposed benefits including reduced post-operative blood loss.Hence, the purpose of this study was to investigate the effect of computer navigation on blood loss and transfusion rate in TKA. We compared the incidence of blood transfusion in patients undergoing computer navigated TKR (n=30) with a cohort of matched patients undergoing conventional TKA (n=30) using intramedullary jig. The groups were matched for age, gender, diagnosis and operative technique. The average blood loss in the drain and the calculated total blood loss were significantly reduced in the navigation group (p<0.001). The incidence of blood transfusion across all BMI's was significantly (p<0.001) less in the computer assisted group compared to the conventional group. Patients with computer navigated procedure had a significantly lower (p<0.001) blood volume loss compared to those who underwent a conventional TKA . There was significant difference in the transfusion rate. This study confirms a significant reduction in total body blood loss between computer assisted and conventional TKA patients. Computer navigation did affect the transfusion rate or those reaching the transfusion trigger. Therefore computer navigation reduces blood loss in TKR with reduced incidence of blood transfusion and this may be clinically relevant to transfusion requirements.
