Prevention of Venous Thromboembolism after Total Hip or Knee Replacement.
This multicenter randomized comparative-effectiveness noninferiority trial compared 30 days of aspirin, warfarin, or rivaroxaban for VTE prophylaxis after elective total hip or knee arthroplasty.
Why it matters
VTE prophylaxis after hip or knee replacement requires balancing prevention of symptomatic thromboembolism against bleeding and other safety events.
