“…However, the volume of blood loss remains high and blood transfusion is necessary in patients with hypovolemic complication. The aim of TKA with the ABN device and/or robotic-assisted surgery is to improve alignment accuracy and reliability of the prosthesis components [15]; however, the advantage of being able to avoid violation of the intramedullary canal may confer a secondary advantage of reducing perioperative blood loss [13]. Prior study in unilateral TKA that compared blood loss between intramedullary non-violating device and the conventional intramedullary-violating technique demonstrated an inconclusive result.…”

“…The accelerometer-based navigation (ABN) device, which is a handheld computer-assisted accelerometer-based stereotaxic system, displays alignment information and guides the bone resection in the operative eld. This system is characterized by an accelerometer gyroscopic wireless pod that is attached to the femoral resection jigs followed by calibration via a prescribed set of steps [14,15]. After alignment veri cation, the femoral bone cut can be performed without violating the femoral canal [16].…”

Background: Total knee arthroplasty (TKA) is associated with significant blood loss and postoperative transfusion. The accelerometer-based navigation (ABN) system guides the bone cutting plane without breaching the intramedullary canal, which may reduce bleeding. This study aimed to investigate blood loss and transfusion compared between the ABN system and the conventional procedure in patients undergoing one-stage sequential bilateral total knee arthroplasty (SBTKA). Methods: A total of 66 patients scheduled for SBTKA were randomly allocated to either the ABN or conventional group. Postoperative hematocrit (Hct) level, drainage blood loss, transfusion rate, and amount of packed red cell transfusion were collected. Total red blood cell (RBC) loss was then calculated for the primary outcome. Results: The mean calculated total RBC loss in the ABN and conventional group was 669.7 and 630.0 mL, respectively (p=0.572). There was no significant difference between groups for other evaluated outcome parameter, including postoperative Hct level, drainage blood loss, or packed red cell transfusion volume. All patients in the conventional group required postoperative blood transfusion while 96.8% of patients in ABN group were transfused. Conclusions: The total RBC loss and volume of packed red cells transfusion were not significant difference between interventions, which suggest no benefit of the ABN system in reducing blood loss and transfusion in patients undergoing SBTKA. Trial registration: The protocol of this study was registered in the Thai Clinical Trials Registry database no. TCTR20201126002 on 26/11/2020.
