Objective  To evaluate the efficacy and safety of tranexamic acid in arthroscopic anterior cruciate ligament reconstruction by meta-analysis. Methods  The databases searched included Embase, PubMed, Cochrane Library, Wanfang, China National Knowledge Infrastructure and Chongqing VIP. The search time range was from the establishment of the databases to September 2022. All randomized controlled trials using tranexamic acid in arthroscopic anterior cruciate ligament reconstruction were collected. The outcome indicators were postoperative blood loss, postoperative joint cavity puncture rate, postoperative hematoma rate, postoperative Visual Analogue Scale score, and postoperative knee joint range of motion. RevMan 5.3 analysis software was selected for meta-analysis. Results  A total of 6 articles were included, including 660 patients. Meta-analysis showed that the postoperative blood loss in the tranexamic acid group was lower than that in the control group [weighted mean difference (WMD)=−24.32 mL, 95% confidence interval (CI) (−33.73 mL, −14.91 mL), P<0.000 01]. The postoperative Visual Analogue Scale score in the tranexamic acid group was lower than that in the control group [WMD=−0.69, 95%CI (−1.21, −0.18), P=0.009]. The postoperative knee joint range of motion in the tranexamic acid group was higher than that in the control group [WMD=2.88°, 95%CI (0.55°, 5.21°), P=0.02]. The postoperative joint cavity puncture rate in the tranexamic acid group was lower than that in the control group [risk ratio (RR)=0.25, 95%CI (0.12, 0.53), P=0.0003]. The postoperative hematoma rate in the tranexamic acid group was lower than that in the control group [RR=0.40, 95%CI (0.21, 0.78), P=0.007]. Conclusion  The patients who used tranexamic acid in in arthroscopic anterior cruciate ligament reconstruction have less postoperative bleeding, lower knee joint puncture rate and hematoma formation rate, which are conducive to pain relief and functional rehabilitation.
