COMPLICATIONS, VENOUS THROMBOEMBOLISM
Venous thromboembolism (VTE) is a serious health issue worldwide. It refers to the abnormal coagulation of blood in the vein. VTE is one of the most important complications after orthopaedic surgery [Currently, the preventive strategies for VTE mainly include pharmacologic and mechanical thromboprophylaxis among patients treated with knee and/or hip replacement. Pharmacologic thromboprophylaxis included direct or indirect thrombin inhibitors, vitamin K antagonists, and factor Xa inhibitors. Mechanical thromboprophylaxis includes graduated compression stockings, intermittent pneumatic compression, venous foot pumps (VFPs), and transcutaneous electrical nerve stimulation [Therefore, the present study aimed to investigate the optimal duration of applying VFP for the prevention of VTE in patients receiving hip and knee arthroplasty. A multicenter prospective clinical trial was conducted to generate high-quality evidence.
