Several modalities have been developed to reduce perioperative blood loss during total knee arthroplasty (TKA) and a navigation system has been successfully introduced in TKA. This study compared the blood loss of navigation-assisted TKA and conventional TKA in the presence of negative or normal pressure drainage. Patients were separated into 3 groups. We enrolled 60 patients undergoing conventional TKA with negative pressure drainage in Group A, and those undergoing navigation-assisted TKA with negative or normal pressure drainage were enrolled in Group B (64 patients) and C (66 patients), respectively. Haemovac drainage volume, reduction of haemoglobin, estimated total blood loss, range of motion at 3 months after surgery, number of blood transfusions and hospitalisation days were all recorded. There were no differences in the demographic data of these 3 groups. Patients in Group B had significantly decreased total drainage volume, estimated total blood loss and blood transfusion rate than those in Group A. The significant reduction of total drainage volume, estimated total blood loss and blood transfusion rate were also noted in Group C when compared with Group B. Patients in Group C had a significantly reduction in haemoglobin, heaemovac drainage volume, estimated total blood loss, blood transfusion rate and hospitalisation days when compared with Group A. Navigation-assisted TKA with normal pressure drainage is a potential modality for the reduction of the haemovac drainage volume, perioperative blood loss and transfusion rate without compromising range of motion at 3 months after surgery.
