Persistent Pulmonary Embolism Rates Following Total Knee Arthroplasty Even With Prophylactic Anticoagulants

These results suggest that some patients may have a genetic predisposition to develop a PE and more effective risk stratification protocols need to be developed to make sure patients receive appropriate anticoagulation.
