General and disease-related data will be collected. All eligible patients must voluntarily sign an informed consent form after understanding and accepting the study. Successfully recruited participants will undergo internal fixation surgery at a scheduled time and then be randomly assigned to either the Venostan (horse chestnut seed extract tablet) group or the conventional treatment group. They will receive the corresponding treatments according to the study protocol. Follow-up assessments will include changes in ankle circumference, ankle range of motion, scale evaluation results, laboratory test results, and adverse events. The study aims to evaluate the effects of Venostasin in patients with ankle fractures undergoing internal fixation surgery, exploring its potential to promote postoperative reduction of ankle swelling, enhance early joint function recovery, and investigate its safety in postoperative fracture management.",[73],"Swelling\u002F Edema",[75,76,77,78,79,80],"Ankle fracture","Edema","Postoperative rehabilitation","horse chestnut seed extract","venostan","enhanced recovery after surgery","2025-07-14",{"date":83,"type":84},"2025-07-16","ACTUAL",{"date":86,"type":84},"2025-04-16",{"date":88,"type":67},"2026-01-12",{"name":5,"class":6},1]
