A recent meta-analysis of eight randomized trials (1,408 total patients) compared aspirin to anticoagulants such as warfarin and dabigatran for preventing venous thromboembolism (VTE) after hip and knee arthroplasty and hip-fracture repair. The analysis found that the overall prophylactic power of these two medical approaches was essentially equal following major lower-extremity surgery. However, the comparison, appearing in the Journal of Hospital Medicine, found a slightly higher (but statistically nonsignificant) risk of deep vein thrombosis (DVT) with aspirin following hip-fracture repair. Conversely, the risk of bleeding after hip-fracture surgery was lower with aspirin than with anticoagulants.
