Abstract
Objective: This study aimed to evaluate the efficacy and safety of intravenous combined with topical application of tranexamic acid (TXA) in reducing blood loss in opening wedge high tibial osteotomy (OWHTO). Methods: A total of 60 patients who underwent unilateral OWHTO between May 2018 and May 2019 were retrospectively reviewed. All the patients were then divided into one of the two groups (30 per group): the TXA group, patients receiving intravenous combined with topical application of TXA, and the control group, patients receiving no TXA. Outcome measures were drain volume, total blood loss, hidden blood loss, transfusion requirements, and incidence of complications. Results: The mean follow-up of TXA group was 14.2 2.3 months (range, 13-16 months) and the mean follow-up for the control group was 14.4 2.1 months (range, 13-17 months). No significant difference was found for the follow-up of two groups (P = 0.829). Drainage volume (143.3 65.4 ml vs 307.8 51.4 mL, P < 0.001), hidden blood loss (156.7 63.8 mL vs 286.4 79.1 mL, P < 0.001) and knee swelling (3.2 0.9 vs 6.5 2.1, P < 0.001) in the TXA group was clearly less than that in the control group, and there was no statistical significance with regard to hospitalization time (P = 0.746), transfusion requirements (P = 1.000), wound complications (P = 0.386), deep venous thrombosis (P = 1.000), postoperative Lysholm knee score (P = 0.681) and Knee Injury & Osteoarthritis Outcome subscales pain (P = 0.752), symp- toms (P = 0.673), activities of daily living (P = 0.871), sport/recreation function (P = 0.816), and knee-related quality of life (P = 0.576) at 6 months postoperatively. Conclusion: This study has shown that administration of intravenous combined with topical TXA in OWHTO can effectively reduce perioperative blood loss without increasing the incidence of postoperative complications.
