Abstract:

BACKGROUND: To date, rivaroxaban has been a clinically common anticoagulant in China; however, effective prophylaxis for venous thrombosis is associated with a markedly higher incidence of perioperative hemorrhagic complications. Although it has been reported that aspirin effectively prevents deep vein thrombosis and pulmonary embolism, the use of aspirin as a routine drug for venous thrombosis after total knee arthroplasty is still controversial.
OBJECTIVE: To compare the efficacy and safety of aspirin and rivaroxaban for prevention of deep vein thrombosis after total knee arthroplasty.
METHODS: Totally 324 patients with osteoarthritis who underwent primary unilateral total knee arthroplasty were randomly divided into three groups. Twelve hours after the surgery, three groups were given aspirin, rivaroxaban and low-molecular-weight heparin respectively. All three groups were treated for 14 days, and all of the patients were followed for 4 weeks.
RESULTS AND CONCLUSION: Compared with the low-molecular-weight heparin group, the incidence of deep vein thrombosis was lower (P < 0.05), but hidden blood loss and wound complications were more common (P < 0.05) in the rivaroxaban group. There were no significant differences between the low-molecular-weight heparin group and aspirin group in the incidence of deep vein thrombosis, hidden blood loss, wound complications or incidences of lower limb swelling and subcutaneous ecchymosis (P > 0.05). The results confirmed that rivaroxaban has a positive anticoagulation effect but leads to increases in wound complications in patients; there are no differences in efficacy and safety between aspirin and low-molecular-weight heparin, so aspirin as part of a multimodal anticoagulation therapy after total knee arthroplasty has good clinical safety and efficacy.
