In this age of evidence-based medicine, the use of medical thrombosis prophylaxis stockings (AES) as a physical strategy for the prevention of lower limb venous thrombosis has been questioned. The current German S3 guidelines even state that their non-application is, in the vast majority of cases, explicitly covered by the recommendations of this guideline. Low molecular weight heparins (NMH) and direct oral anticoagulants (DOAK) have received approval for thrombosis prophylaxis in elective knee and hip joint replacement, but the use of AES is absent from these approval studies. The results of the additional effects of the AES in the approval studies of Edoxaban were published for the first time. According to these results, the incidence of venous thromboembolism was 6.0% when AES were worn and 13.0% when AES were not worn. Since the approval studies of NMH and the DOAKs did not control for the use of AES, the impact of AES on the overall results remains unclear. Therefore the study results are only valid in the context of the general application of AES. Guidelines commissions should take this into account in their recommendations.
