ABSTRACT Despite developments in prophylactic methods, venous thromboembolism (VTE) continues to be a serious complication following total joint arthroplasty. The new AAOS/ACCP guidelines on preventing pulmonary embolism (PE) after total hip/knee arthroplasty (THA/TKA) do not make specific recommendations for bilateral vs. unilateral procedures. In-patient PE rates were examined for patients undergoing unilateral or simultaneous bilateral TKA/THA at our institution in 2011. Of the 7,437 THA/TKA surgeries completed at our institution in 2011, 36 patients suffered from PE (0.48%). The rate of PE for unilateral TKA was 0.61% vs. 1.87% for bilateral (P<0.001) and for unilateral THA was 0.17% vs. 0.52% for bilateral THA. Despite patients being screened before being cleared to undergo bilateral THA/TKA, they remain at higher risk for VTE.

    ABSTRACT: IntroductionFew literatures have studied the blood management in patients treated with staged bilateral primary total knee arthroplasty (TKA) in a single hospitalization period. Therefore, this study aims to evaluate the effectiveness and safety of the newly introduced multimodal blood management (MBM) in these patients.Materials and methodsWe retrospectively compared the perioperative parameters in 70 cases undergoing staged bilateral primary TKA in a single hospitalization period from 2012¿2013 in a single center with two different groups of patients, allocating cases to the group with the newly introduced MBM (Group A, n =33) and controls to the group without the newly introduced MBM (Group B, n =37). The newly introduced MBM protocols include preoperative hemoglobin (Hb) evaluation, high protein diet, tourniquet release after skin closure, preoperative oral iron treatment and femoral canal obturation, and one dose of tranexamic acid (TXA) IV with another one if necessary. While in the control group, only routine blood-saving techniques were used.ResultsGroup A had a transfusion rate of 9% (3/33), whereas 32.4% of patients (12/37) in Group B received allogenic blood transfusion. Significant benefits were also found in Group A in terms of postoperative Hb and hematocrit (Hct), reduction of postoperative pain, swelling, postoperative pain, length of stays, and hospital costs. No deep vein thrombosis (DVT) events were found in all these patients.Conclusions The newly introduced MBM in staged bilateral TKA in a single hospitalization period can reduce blood loss effectively as well as pain and knee joint swelling instead of leading to increased complications and result in significant cost savings.

    ABSTRACT: Background Venous thromboembolism (VTE) remains a cause of significant morbidity and mortality following total hip arthroplasty (THA) and total knee arthroplasty (TKA). Prophylaxis significantly reduces the rate of VTE following these procedures. Previous studies report sub-optimal uptake of guideline recommended thromboprophylaxis.AimsTo describe VTE prophylaxis prescribing practices in a major hospital for joint replacement surgery. To determine the proportion of patients receiving guideline recommended thromboprophylaxis. To define the incidence of in-hospital VTE following THA and TKA.MethodsA retrospective chart review of 402 consecutive patients undergoing THA or TKA from June to October 2013. Patient characteristics, operative and anaesthetic factors, details of thromboprophylaxis and the incidence of in-hospital VTE are reported. Comparison is made with recent guidelines.Results402 patients underwent THA (n=202) or TKA (n=200). 99% of patients received mechanical prophylaxis. 100% of patients received chemoprophylaxis in hospital. Enoxaparin was most commonly prescribed followed by aspirin. Patients undergoing TKA were more likely to receive an anticoagulant (89.9% vs 47.8% for THA, p <0.05). 74.5% received chemoprophylaxis on discharge (mean duration 22.1 days). The incidence of in-hospital VTE was 4.7%.Conclusions The proportion of study patients receiving thromboprophylaxis compares favourably with prior research. The overall incidence of VTE is higher than that demonstrated in major orthopaedic trials. Inadequate duration of chemoprophylaxis remains a potential area of improvement. Extended prophylaxis should be prescribed as per current guidelines. Comparison between efficacy and safety of various agents is the subject of future research.
