Venous thromboembolism (VTE) prophylaxis after total joint arthroplasty is considered best practice.

The American Academy of Orthopaedic Surgeons and the American College of Chest Physicians published their most recent clinical practice guidelines about VTE prophylaxis in 2011 and 2012, respectively.
