Thromboprophylaxis of Patients Submitted to Total Hip and Knee Arthroplasty: A Cost-Effectiveness Assessment From the Perspective of the Brazilian National Health System.

Objectives: Venous thromboembolism (VTE) is a serious national and international public health issue. Major orthopedic surgeries, such as a total hip (THA) and knee (TKA) arthroplasties, are associated with an increased risk of VTE, long-term complications, functional disability, and death resulting from hypercoagulability by surgical trauma. This pharmacoeconomic analysis aimed to identify the most cost-effective anticoagulant alternative in preventing VTE in patients undergoing THA and TKA.
