Abstract

Background: Tranexamic acid (TXA) is a medication that has been shown to decrease blood loss and risk of blood transfusion in total knee and total hip arthroplasty. The purpose of this study was to evaluate the use of TXA in patients undergoing total ankle arthroplasty (TAA). We hypothesized there would be less blood loss and wound complications in patients receiving TXA.

Methods: A retrospective review of 2 patient cohorts operated on by 2 surgeons was performed from 2010 to 2018. We compared a group of TAA patients that did not receive TXA vs a subsequent group that received TXA. Patients received 1g intravenous TXA before the tourniquet was inflated followed by another 1 g after release of the tourniquet. Intraoperative blood loss was recorded and preoperative hemoglobin and hematocrit levels were compared to postoperative levels. Intraoperative and postoperative complications were compared between the 2 groups. A total of 119 patients were included in the study, of whom 55 received TXA. No significant difference existed between the 2 groups in gender, age, body mass index, or Charlson comorbidity index.

Results: There was no difference in estimated blood loss, postoperative hemoglobin/hematocrit values or preoperative to postoperative change in hemoglobin/hematocrit values. Additionally, there was no difference in wound complications or overall complication rate between the groups.

Conclusion: TXA has been shown to be effective in total knee and total hip arthroplasty in decreasing blood loss and transfusion risk. We did not find it to be effective in reducing intraoperative blood loss, perioperative blood loss, or wound complications in TAA.

Level of evidence: Level III, comparative study.
