BACKGROUND Prophylaxis for venous thromboembolism is recommended for at least 10 days after total knee arthroplasty; oral regimens could enable shorter hospital stays. We aimed to test the efficacy and safety of oral rivaroxaban for the prevention of venous thromboembolism after total knee arthroplasty. METHODS In a randomised, double-blind, phase III(More)
OBJECTIVE To determine the efficacy and safety of the anticoagulant fondaparinux in older acute medical inpatients at moderate to high risk of venous thromboembolism. DESIGN Double blind randomised placebo controlled trial. SETTING 35 centres in eight countries. PARTICIPANTS 849 medical patients aged 60 or more admitted to hospital for congestive(More)
BACKGROUND Elective hip-replacement surgery carries significant risk of venous thromboembolism, despite use of thromboprophylaxis. We aimed to see whether the pentasaccharide fondaparinux, the first drug of a new class of synthetic antithrombotic agents, could reduce this risk to a greater extent than other available treatments. METHODS In a double-blind(More)
BACKGROUND Low-molecular-weight heparins such as enoxaparin are preferred for prevention of venous thromboembolism after major joint replacement. Apixaban, an orally active factor Xa inhibitor, might be as effective, have lower bleeding risk, and be easier to use than is enoxaparin. We assessed efficacy and safety of these drugs after elective total knee(More)
BACKGROUND Despite use of thromboprophylaxis, elective hip-replacement surgery carries a high risk of venous thromboembolic complications. We aimed to assess the ability of the pentasaccharide fondaparinux, the first of a new class of synthetic antithrombotic agents, to further reduce this risk. METHODS In a double-blind study, we randomly assigned 2309(More)
A once-daily dose of rivaroxaban 10 mg, an oral, direct Factor Xa inhibitor, was compared with enoxaparin 40 mg subcutaneously once daily for prevention of venous thromboembolism in three studies of patients undergoing elective hip and knee replacement (RECORD programme). A pooled analysis of data from these studies (n = 9581) showed that rivaroxaban was(More)
BACKGROUND The benefit of thromboprophylaxis for 1 month has never been evaluated in patients undergoing hip fracture surgery, a setting in the highest risk category for postoperative venous thromboembolism (VTE). METHODS In a double-blind multicenter trial, 656 patients undergoing hip fracture surgery were randomly assigned to receive prophylaxis with a(More)
Venous thromboembolism is a frequent and potentially life-threatening complication of orthopedic surgery. Rivaroxaban is an oral direct factor Xa inhibitor, which was shown to be effective for the prevention of venous thromboembolism after elective hip and knee arthroplasty in the RECORD study program. Rivaroxaban has the potential to overcome the(More)
In Western countries, venous thromboembolism (VTE) is a widespread and serious disorder, with hospital admission rates that appear to be increasing. Current anticoagulant therapies available for the prevention and treatment of VTE have several drawbacks that make them either difficult to manage effectively, due to a need for careful monitoring to control(More)
