Establishing a universal protocol for deep vein thrombosis following orthopedic surgery: total knee arthroplasty.

Overview

The incidence of deep vein thrombosis (DVT) after total knee replacement surgery is reported to occur in 84% of all unprotected patients and may be as high as 68% in patients who receive DVT prophylaxis. Moreover, controversy exists as to which pharmacologic or mechanical agent is most effective. Although the scientific literature provides some answers, many issues of DVT prophylaxis are not completely addressed, especially with regard to the duration of prophylaxis. The most recent report from the American College of Chest Physicians Consensus Conference on Antithrombotic Therapy reconfirms the recommendations offered from previous consensus groups on the importance of establishing and applying a universal protocol for the prevention of DVT in orthopedic surgery.
