In this narrative review of the real-world effectiveness and safety of pharmacological thromboprophylaxis following primary total hip and knee arthroplasty, a total of 12 non-interventional observational studies were included. Pharmacological thromboprophylaxis included warfarin, heparins, dabigatran, rivaroxaban, apixaban, acetylsalicylic acid, and fondaparinux. The absolute risks varied across the included studies. These variations can be explained by differences in patient populations, drug exposure, follow-up time, and definition of outcomes, which makes it a challenge to compare the risk estimates. These findings emphasize the need for a large population-based real-world study to provide comparable risk estimates associated with different pharmacological thromboprophylaxis.
