Compared with placebo, iv 10 mg/kg (3 doses), iv 1 g, iv 1 g + top 2 g, iv 2 g + top 1 g, and iv 50 mg/kg decreased the hemoglobin drop with statistical significance. No statistically significant difference was found when the two interventions were compared against each other for the occurrence of DVT and hematoma (p > 0.05). The SUCRA shows that iv 10 mg/kg ranked first for reducing total blood loss (SUCRA, 90.7%) and drainage volume (SUCRA, 94.3%). The SUCRA shows that iv 1 g + top 2 g ranked first (SUCRA, 93.7%) for reducing hemoglobin drop.</p><p><strong>Conclusion: </strong>Administration with TXA was associated with a decrease in blood loss in HTO patients. The optimal dose of TXA for reducing blood loss was iv 10 mg/kg. As for reducing hemoglobin drop, iv 1 g + top 2 g ranked first. Administration of TXA was not associated with an increase in the occurrence of DVT and hematoma. However, most evidence was graded as low/very low confidence due to study limitations, imprecision, and heterogeneity. Therefore, these findings should be interpreted as preliminary signals rather than definitive conclusions. Further high-quality randomized trials are required to validate dose-dependent efficacy and long-term safety outcomes.</p>","PeriodicalId":19566,"journal":{"name":"Orthopaedic Surgery","volume":" ","pages":"2784-2808"},"PeriodicalIF":2.1,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12497536/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145041006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
