BLOOD LOSS, HEMODYNAMIC INSTABILITY, BLOOD LOSS, COMPLICATION
Blood loss is a complication of considerable concern following total knee arthroplasty (TKA), especially in the early postoperative period. This condition can lead to hemodynamic instability and requires blood transfusion in those who become hypovolemic [There are two forms of blood loss in TKA. The first is visible blood loss, which is defined as blood loss in the surgical field and drainage. The second is invisible or hidden blood loss, which refers to blood loss within tissues, the intramedullary canal, and bony surfaces [Data specific to blood loss and transfusion rate between the conventional technique and the non-breaching intramedullary canal technique in patients undergoing one-stage SBTKA remain scarce. Accordingly, the aim of this study was to investigate blood loss and transfusion compared between the ABN system and the conventional procedure in patients undergoing one-stage SBTKA.
