Objective: After knee surgeries, the intra-articular administration of a solution mixing bupivacaine and epinephrine is a common regimen. It is logic to expect the potential in blood conservation using this regimen in total knee arthroplasty (TKA); however, there is inconsistent literature. The study was to explore the hemostatic efficacy of this regimen in our primary TKAs without drains.
