The efficacy and safety of tranexamic acid utilization in total ankle arthroplasty: a systematic review and meta-analysis.

INTRODUCTION

There is still a lack of information on the role of Tranexamic acid (TXA) in total ankle arthroplasty (TAA). The purpose of this study is to comprehensively review, consolidate, and analyze findings from existing research on the effectiveness and safety of TXA in TAA.

MATERIALS AND

METHODS

The comprehensive literature review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) using PubMed, Embase, Web of Science, and Cochrane databases, for original, English-language studies investigating the efficacy and safety of TXA in TAA, through February 2023. Evaluated data for the meta-analysis included estimated blood loss (EBL), change in perioperative hemoglobin, need for transfusion, and complications including DVT/PE, and wound complications.

RESULTS

A total of nine studies were included in this study. In total, 450 TAA were included, with 244 receiving TXA (54.2%) and 206 not receiving TXA (45.8%). TXA in TAA significantly decreased EBL. A significantly lower rate of wound complications in the TXA group with the relative risk (RR) of 0.51. We classified wound complications into wound infection and delayed wound healing/dehiscence. A significant decrease in the rate of wound infection and a tendency showing a decrease in the rate of delayed wound healing/dehiscence in the TXA group were noted: the RR of 0.29, and 0.63, respectively. TXA did not increase the incidence of DVT/PE following TAA.

CONCLUSIONS

In conclusion, the utilization of TXA during TAA demonstrated a statistically significant reduction in EBL and relative risk for wound complications. However, further RCTs with larger sample sizes will be necessary to establish a more robust conclusion regarding the efficacy and safety of TXA in TAA.

LEVEL OF EVIDENCE: Level III, systematic review and meta-analysis.
