Aspirin Is as Effective as Newer Anticoagulants in Preventing VTE after TKA Study Finds

A study recently published online by JAMA Surgery reports that the use of aspirin may be just as effective as the use of newer, more expensive anticoagulants such as enoxaparin (Lovenox) and rivaroxaban (Xarelto) in preventing venous thromboembolism (VTE) after primary total knee arthroplasty  which could help reduce costs for the nearly 1 million Americans who have knee replacement surgery each year.
