Since the introduction of the National Institute
for Health and Care Excellence (NICE) guidelines on thromboprophylaxis
and the use of extended thromboprophylaxis with new oral agents,
there have been reports of complications arising as a result of
their use. We have looked at the incidence of wound complications
after the introduction of
Aims. We investigated the efficacy and safety profile of commonly used venous thromboembolism (VTE) prophylaxis agents following hip and knee arthroplasty. Methods. A systematic search of PubMed, Embase, Cochrane Library, Web of Science, and OrthoSearch was performed. Prophylaxis agents investigated were aspirin (< 325 mg and ≥ 325 mg daily), enoxaparin, dalteparin, fondaparinux, unfractionated heparin, warfarin, rivaroxaban, apixaban, and
Aims. There is uncertainty regarding the optimal means of thromboprophylaxis
following total hip and knee arthroplasty (THA, TKA). This systematic
review presents the evidence for acetylsalicylic acid (aspirin)
as a thromboprophylactic agent in THA and TKA and compares it with
other chemoprophylactic agents. Materials and Methods. A search of literature published between 2004 and 2014 was performed
in accordance with Preferred Reporting Items for Systematic Reviews
and Meta-Analyses guidelines. A total of 13 studies were eligible
for inclusion. Results. Evidence from one good quality randomised controlled trial (RCT)
showed no difference in rates of venous thrombo-embolism (VTE) in
patients given aspirin or low molecular weight heparin (LMWH) following
TKA. There was insufficient evidence from trials with moderate to
severe risk of bias being present to suggest aspirin is more or
less effective than LMWH, warfarin or
