Retrospective cohort study of 11,373 patients undergoing primary unilateral THA or TKA (2000–2008) using a validated formula to calculate perioperative blood loss and multivariate analysis to identify independent predictors of both blood loss and allogeneic transfusion requirement.
When risk-stratifying a TJA patient preoperatively, flag male sex, Charlson Comorbidity Index >3, and planned autologous donation as drivers of higher total blood loss — and counsel patients that autologous donation reliably lowers allogeneic transfusion exposure but does not reduce overall bleeding.
In THA specifically, regional anesthesia is the modifiable factor with the strongest evidence for blood conservation.
