Both total knee arthroplasty and total hip arthroplasty are successful operations that can improve a patient’s quality of life. Unfortunately, some patients will develop symptomatic pulmonary embolism or deep vein thrombosis after this surgery. If no prophylaxis is used, historical data suggest that 40–60% of patients will develop an asymptomatic deep vein thrombosis and that 0.5–2% of patients may die of a pulmonary embolism [1,2]. If modern prophylaxis techniques are used, these rates are reduced to 0.5–1% of patients who will ever develop a symptomatic venous thromboembolism (VTE), although significant variation in rates exist [3]. Therefore, there is great interest among surgeons in providing patients with appropriate VTE prophylaxis. The selection of the specific VTE regimen is a balance between efficacy and safety. Orthopedic surgeons are particularly concerned about postoperative bleeding, which can lead to reoperation for evacuation of a hematoma, infection and limited range of motion in a total knee arthroplasty [4]. At the present time, the ideal prophylaxis regimen has not been identified but clinical practice guidelines have been developed that can be useful to orthopedic surgeons in selecting an appropriate prophylaxis regimen for their patients.
