In the early era of TKA 40% to 80% of patients developed postoperative venous thromboembolism (VTE) [

Although clinicians identified a large portion of these patients during routine postoperative screening studies and found those clots were resolved on followup imaging, great efforts were made to decrease VTE and its associated morbidity and mortality. Patients now mobilize much earlier thanks in large part to improvements in controlling pain and nausea with multimodal analgesia. Early mobilization can generally mitigate the venous stasis portion of Virchow’s triad of stasis, hypercoaguability, and intimal injury. Pharmacologic prophylaxis seeks to address the hypercoagulable state of the patient who may not be very mobile in the days immediately after surgery. …
