[The role of NOAC in orthopaedic surgery - pros and cons].

The risk for venous thromboembolism (VTE) is high in orthopaedic surgery in the lower extremities and pelvis. New oral anticoagulants (NOAC) have been shown to be efficient and safe as thrombosis prophylaxis after hip and knee arthroplasty surgery. The increased use of NOAC as prophylaxis in atrial fibrillation patients causes new problems in acute and elective surgery.
