Abstract
BACKGROUND Venous thromboembolism (VTE) following revision total joint arthroplasty (TJA) poses significant risks despite prophylactic measures. The optimal VTE prophylaxis agent for revision TJA remains unclear. This study aimed to compare aspirin against various anticoagulant agents regarding efficacy and safety in preventing symptomatic VTE events after revision TJA. METHODS A retrospective analysis included 4,575 patients undergoing revision TJA between 2008 and 2020. Of these, 2,091 received aspirin, while 2,484 received other anticoagulants. Demographic, procedural, and outcome data were collected. Logistic regression models were used to identify predictors of symptomatic VTE. RESULTS The aspirin group showed a significantly lower incidence of symptomatic VTE compared to the other anticoagulant group (0.53 versus 2.54%, P < .001). Logistic regression confirmed a higher risk of VTE with other anticoagulants (odds ratio: 0.2 to 0.26, P < .001), while blood transfusion (odds ratio: 2.72, P = .001) were identified as risk factors. CONCLUSIONS This study demonstrated that aspirin is a viable and potentially safer option than other anticoagulants, exhibiting comparable efficacy in preventing VTE events in revision TJA. Balancing effectiveness and safety is crucial, considering patient-specific risk factors and bleeding tendencies. This large cohort study demonstrated that aspirin was associated with a more effective and safer VTE prophylaxis agent, compared to other anticoagulants, in patients undergoing revision TJA.

Bergstein VE, Taylor WL, Weinblatt AI, Lesser LC, Long WJ. The Financial Burden of Aspirin versus Oral Factor Xa Inhibitors for Thromboprophylaxis Following Total Knee Arthroplasty. J Arthroplasty 2024; 39:935-940. [PMID: 37858709 DOI: 10.1016/j.arth.2023.10.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Revised: 10/03/2023] [Accepted: 10/06/2023] [Indexed: 10/21/2023] Open
Abstract
BACKGROUND Aspirin and oral factor Xa inhibitor thromboprophylaxis regimens are associated with similarly low rates of venous thromboembolism following total knee arthroplasty (TKA). However, the rate of prosthetic joint infection (PJI) is lower with aspirin use. This study aimed to compare the cost differential between aspirin and factor Xa inhibitor thromboprophylaxis with respect to PJI management. METHODS We used previously published rates of PJI following aspirin and factor Xa inhibitor thromboprophylaxis in primary TKA patients at a single, large institution. Prices for individual drugs were obtained from our hospital's pharmacy service. The cost of PJI included that of 2-stage septic revision, with or without the cost of 1-year follow-up. National data were obtained to determine annual projected TKA volume. RESULTS The per-patient costs associated with a 28-day course of aspirin versus factor Xa inhibitor thromboprophylaxis were $17.36 and $3,784.20, respectively. Including cost of follow-up, per-patient costs for a 28-day course of aspirin versus factor Xa inhibitors increased to $73,358.76 and $77,125.60, respectively. The weighted average per-patient costs for a 28-day course were $237.38 and $4,370.93, respectively. The annual cost difference could amount to over $14.1 billion in the United States by 2040. CONCLUSIONS The per-patient cost associated with factor Xa inhibitor thromboprophylaxis is as much as 1,980.6% higher than that of an aspirin regimen due to increased costs of primary treatment, differential PJI rates, and high costs of management. In an era of value-based care, the use of aspirin is associated with major cost advantages.

Sci Rep 2023; 13:22024. [PMID: 38086979 PMCID: PMC10716409 DOI: 10.1038/s41598-023-49291-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Accepted: 12/06/2023] [Indexed: 12/18/2023] Open
Abstract
It is unclear whether manual lymphatic drainage (MLD) following primary total knee arthroplasty (TKA) is effective in reducing pain and swelling and improving knee function. The present study investigated the efficacy of MLD after TKA. The outcomes of interest are the range of motion (ROM), pain (visual analogue scale, VAS), and circumference of the lower leg. This meta-analysis was conducted according to the 2020 PRISMA statement. In November 2023, the following databases were accessed: PubMed, Web of Science, Google Scholar, and Embase, with no time constraint. Only level I evidence studies, according to the Oxford Centre of Evidence-Based Medicine, were considered. All the randomised controlled trials (RCTs) comparing patients who have received MLD versus a group of patients who did not undergo MLD following primary TKA were accessed. Data from four RCTs (197 TKAs) were retrieved. 67% (132 of 197 patients) were women. The mean length of follow-up was 7.0 ± 5.8 weeks. The mean age of the patients was 69.6 ± 2.7 years, and the mean BMI was 28.7 ± 0.9 kg/m2. At baseline, between-group comparability was evidenced in the male:female ratio, mean age, mean BMI, knee flexion, and VAS. No difference was found in flexion (P = 0.7) and VAS (P = 0.3). No difference was found in the circumference of the thigh (P = 0.8), knee (P = 0.4), calf (P = 0.4), and ankle (P = 0.3). The current level I of evidence does not support the use of MLD in primary TKA.
