Tranexamic acid (TXA) and ε-aminocaproic acid (EACA) are two drugs shown to limit blood loss following major surgery, from cardiac to orthopedic procedures. Yet compared to tranexamic acid (TXA), research on the clinical impact of ε-aminocaproic acid (EACA) in total knee arthroplasty (TKA) is limited. The primary aim of this study is to determine whether TXA and EACA provide similar blood decreasing effects following TKA or whether one drug provides a superior effect over the other in reducing patients' blood loss.
