Abstract: Objective To compare the influence of anticoagulant therapy on the curative effect after total knee arthroplasty and evaluate the necessity, effectiveness and safety of anticoagulant therapy. Methods 154 patients after total knee arthroplastyfrom January 2010 to August 2013 in our department were divided into the rivaroxaban group (group A), the enoxaparin group (B group) and non anticoagulation group (group C) according to the treatments. It was observed that the postoperative venous thromboembolism incidence; changes of blood coagulation indexes before and after the operation; the total blood loss、dominant blood loss and hidden hemorrhage; the wound; the HSS score of knee function. Results None of postoperative venous thromboembolism occurred in group A and B, three cases of venous thromboembolism in group C;The differences of between preoperative and postoperative coagulation indexes in three groups had no statistical significance (P>0.05); Dominant blood loss in group B was significantly higher than that of group A (P<0.05); No statistical significance in the HSS scores of knee function of three group (P>0.05). Conclusion The effect of anticoagulant drugs on the prevention of venous thromboembolism after total knee arthroplasty is effective, same efficacy in the treatment with rivaroxaban or enoxaparin; anticoagulant therapy does not significantly increase the postoperative blood loss and the incidence of wound complications, does not influence the recovery of postoperative mid-term knee function. The use of anticoagulation therapy after total knee arthroplasty has good effect and be safety.
