Clinical experience with novel oral anticoagulants for thromboprophylaxis after elective hip and knee arthroplasty.

Anticoagulant medications help to reduce the risk of thromboembolic events after total hip arthroplasty and total knee arthroplasty. Traditionally, this has been accomplished with medications, such as low-molecular-weight heparin and warfarin. However, these traditional anticoagulants possess a variety of shortcomings that leave much room for improvement. A new class of oral anticoagulants is now available, and present a more convenient option for safe and efficacious thromboprophylaxis in post arthroplasty patients, particularly in the outpatient setting. This review focuses on the direct thrombin inhibitor, dabigatran, and the selective factor Xa inhibitors, rivaroxaban and apixaban, and the clinical data to date about their use in total hip arthroplasty and total knee arthroplasty patients.
