Abstract
BACKGROUND The aim of this study was to perform a population-level analysis on the effect of different types of anticoagulation on postoperative stiffness after total knee replacement, requiring manipulation under anesthesia. We hypothesized that patients receiving warfarin would have a higher rate of manipulation under anesthesia compared with patients receiving low-molecular-weight heparin. We also hypothesized that aspirin, direct factor Xa inhibitors, and fondaparinux would have no effect on the rate of manipulation under anesthesia. METHODS Using the PearlDiver patient database, we analyzed 32,320 patients who underwent a primary unilateral total knee replacement from 2007 to 2015. Patients were included if they filled a prescription for anticoagulation medication within 2 days of their discharge and were excluded if they were taking a prescription anticoagulation medication (except for aspirin) in the 3 months before total knee replacement. The primary outcome was manipulation under anesthesia performed within 6 months after a primary total knee replacement. RESULTS The most commonly prescribed postoperative anticoagulation was warfarin (38.0%), followed by low-molecular-weight heparin (33.8%). There were 1,178 patients (3.64%) who underwent manipulation under anesthesia within 6 months of total knee replacement. In multivariable analysis using low-molecular-weight heparin as a comparison group and accounting for age, sex, comorbidities, and length of stay, there was a significant increase in the risk of manipulation under anesthesia for patients who received warfarin (hazard ratio [HR], 1.17 [95% confidence interval (CI), 1.01 to 1.36]; p = 0.032), direct factor Xa inhibitors (HR, 1.42 [95% CI, 1.20 to 1.66]; p < 0.001), or fondaparinux (HR, 1.33 [95% CI, 1.01 to 1.72]; p = 0.038). Although patients who received aspirin had the same risk estimate as patients who received warfarin, there was not a significantly increased risk of manipulation under anesthesia in patients who received aspirin compared with low-molecular-weight heparin (HR, 1.17 [95% CI, 0.72 to 1.80]; p = 0.493). CONCLUSIONS We found an increased rate of manipulation under anesthesia after total knee replacement in patients who received oral anticoagulants including warfarin, direct factor Xa inhibitors, and fondaparinux, in comparison with patients who received aspirin or low-molecular-weight heparin. We recommend that patients receiving oral anticoagulants after total knee replacement should be counseled about associated stiffness. Furthermore, surgeons should take these data into account when selecting thromboprophylaxis for patients after total knee replacement. LEVEL OF EVIDENCE Therapeutic Level III.

Low-Dose Aspirin Is Safe and Effective for Venous Thromboembolism Prophylaxis Following Total Knee Arthroplasty. J Arthroplasty 2018; 33:S131-S135. [PMID: 29656974 DOI: 10.1016/j.arth.2018.03.001] [Citation(s) in RCA: 54] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/04/2017] [Revised: 03/02/2018] [Accepted: 03/03/2018] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND Aspirin is an effective prophylaxis for venous thromboembolism (VTE) after total knee arthroplasty (TKA). The optimal prophylactic aspirin dose has not been established. The study aims to compare 2 aspirin regimens with regard to the incidence of (1) symptomatic deep venous thrombosis (DVT), (2) pulmonary embolism (PE), (3) bleeding, and (4) mortality within 90 days after TKA. METHODS We retrospectively identified 5666 patients who received aspirin twice daily for 4 to 6 weeks after TKA. A total of 1327 patients received 81-mg BID and 4339 patients received 325-mg BID aspirin. Postoperative complications collected were VTEs (DVT and PE), bleeding (gastrointestinal or wound bleeding), and mortality. RESULTS The incidence of VTE was 1.5% in the 325-mg group and 0.7% in the 81-mg group (P = .02). Symptomatic DVT was 1.4% in the 325-mg aspirin compared with 0.3% for the 81-mg aspirin (P = .0009). Regression model showed no correlation between aspirin dose and VTE incidence (odds ratio [OR] = 1.03; 95% confidence interval [95% CI], 0.45-2.36; P = .94) or DVT (OR = 0.50; 95% CI, 0.16-1.55; P = .20). The incidence of PE was 0.2% in the high-aspirin group compared with 0.4% in the low-aspirin group (P = .13). Bleeding was 0.2% in the 325-mg aspirin group and 0.2% in the 81-mg aspirin group (P = .62), and 90-day mortality was similar (0.1%) between the groups (P = .56). CONCLUSION Low-dose aspirin was not inferior to high-dose aspirin for the prevention of VTE after TKA. Low-dose aspirin can be considered a safe and effective agent in the prevention of VTE after TKA.

Abstract
Objective To develop a quality improvement initiative to reduce the incidence of pulmonary embolism (PE) following elective lower extremity joint replacement surgery. Methods 866 Patients undergoing a total knee or total or partial hip replacement surgery at a from 2014 to 2016 were included in this prospective pre-post interventional study. Results There were 13 PE's before the intervention and 2 after the intervention. The incidence of PE was significantly higher prior to the intervention (2.8% vs. 0.7%; p = 0.044). Conclusions Our results suggest that our bundle of interventions was successfully implemented and helped to reduce the incidence of pulmonary embolism following surgery.

Abstract
There are limited data to guide the use of venous thromboembolism disease (VTED) prophylaxis after foot and ankle surgery. Although there is general consensus that the overall risk is lower than after hip or knee replacement, subpopulations of patients may be at relatively heightened risk. Furthermore, existing data are often conflicting regarding the efficacy of prophylaxis, with little acknowledgment of the tradeoffs between VTED prophylaxis and potential complications associated with the use of such medications. This article provides an overview of currently available evidence to guide decision making regarding VTED prophylaxis in patients who undergo foot and ankle surgery.

Abstract
Objectives: To evaluate the effectiveness of aspirin as prophylaxis for deep venous thrombosis (DVT) in patients undergoing total hip arthroplasty (THA), and to analyze the incidence of bleeding during the post-operative period. Methods: This prospective study carried out in 2017 consisted of 37 patients indicated for THA with high risk for DVT. Immediately after the procedure, aspirin, elastic compression socks and early deambulation were initiated. Doppler ultrasound was performed in the legs 6 days and 6 weeks post-procedure to rule out venous thromboembolism. Hematometric variables and clinical criteria were used to detect bleeding. Results: The incidence of VTE (venous thromboembolism) 6 days post-procedure was 21.6%. By 6 weeks post-procedure, it dropped to 8.1%, (p = 0.102). Only 2.7% were diagnosed with VTE, 6 days and also 6 weeks post-procedure. Within the immediate postoperative period, hemoglobin was lower (p < 0.001), in contrast to 6 weeks after surgery, when it returned to baseline levels. Conclusion: Aspirin was an effective chemical prophylaxis for venous thromboembolism in high-risk patients who underwent THA. There was no clinical record of postoperative bleeding and hematometric levels suggested that there was no chronic bleeding. Level of Evidence II; Prospective study.

Abstract
Aims The aims of this study were to compare the efficacy of two agents,
aspirin and warfarin, for the prevention of venous thromboembolism
(VTE) after simultaneous bilateral total knee arthroplasty (SBTKA),
and to elucidate the risk of VTE conferred by this procedure compared
with unilateral TKA (UTKA). Patients and Methods A retrospective, multi-institutional study was conducted on 18
951 patients, 3685 who underwent SBTKA and 15 266 who underwent
UTKA, using aspirin or warfarin as VTE prophylaxis. Each patient
was assigned an individualised baseline VTE risk score based on
a system using the Nationwide Inpatient Sample. Symptomatic VTE,
including pulmonary embolism (PE) and deep vein thrombosis (DVT),
were identified in the first 90 days post-operatively. Statistical
analyses were performed with logistic regression accounting for
baseline VTE risk. Results The adjusted incidence of PE following SBTKA was 1.0% (95% confidence
interval (CI) 0.86 to 1.2) with aspirin and 2.2% (95% CI 2.0 to
2.4) with warfarin. Similarly, the adjusted incidence of VTE following
SBTKA was 1.6% (95% CI 1.1 to 2.3) with aspirin and 2.5% (95% CI
1.9 to 3.3) with warfarin. The risk of PE and VTE were reduced by
66% (odds ratio (OR) 0.44, 95% CI 0.25 to 0.78) and 38% (OR 0.62,
95% CI 0.38 to 1.0), respectively, using aspirin. In addition, the risk
of PE was 204% higher for patients undergoing SBTKA relative to
those undergoing UTKA. For each ten-point increase in baseline VTE
risk, the risk of PE increased by 25.5% for patients undergoing
SBTKA compared with 10.5% for those undergoing UTKA. Patients with
a history of myocardial infarction or peripheral vascular disease had
the greatest increase in risk from undergoing SBTKA instead of UTKA. Conclusion Aspirin is more effective than warfarin for the prevention of
VTE following SBTKA, and serves as the more appropriate agent for
VTE prophylaxis for patients in all risk categories. Furthermore,
patients undergoing SBTKA are at a substantially increased risk
of VTE, even more so for those with significant underlying risk
factors. Patients should be informed about the risks associated
with undergoing SBTKA. Cite this article: Bone Joint J 2018;100-B(1

Abstract
Introduction
Currently there are no consensuses in the national guidance on thromboprophylaxis following major elective lower limb surgery. Emerging clinical evidence suggests that aspirin could be just as effective as anticoagulants with a lower cost. The aim of this study was to provide an update based on literature of the past 3 years for the use of aspirin as thromboprophylaxis after knee and hip arthroplasty.
Materials and Methods
MEDLINE/EMBASE search was performed with appropriate terms for original articles from 2014 to 2017.
Results
Eight articles were found. Five articles concluded that aspirin was an effective prophylactic. The collation of results on the deep vein thrombosis rate involved 43,012 patients who were prescribed aspirin, of which 283 (0.66%) suffered from symptomatic deep vein thromboses. Aspirin was noted for its good side effect profile and cost effectiveness. It was noted that anticoagulants had a higher rate of complications, including bleeding and wound-oozing.
Conclusion
Aspirin is an effective and safe prophylactic against deep vein thrombosis following major elective lower limb arthroplasty surgery.

Abstract
The number of arthroplasties being performed
increases each year. Patients undergoing an arthroplasty are at
risk of venous thromboembolism (VTE) and appropriate prophylaxis
has been recommended. However, the optimal protocol and the best
agent to minimise VTE under these circumstances are not known. Although
many agents may be used, there is a difference in their efficacy
and the risk of bleeding. Thus, the selection of a particular agent relies
on the balance between the desire to minimise VTE and the attempt
to reduce the risk of bleeding, with its undesirable, and occasionally
fatal, consequences. Acetylsalicylic acid (aspirin) is an agent for VTE prophylaxis
following arthroplasty. Many studies have shown its efficacy in
minimising VTE under these circumstances. It is inexpensive and
well-tolerated, and its use does not require routine blood tests.
It is also a ‘milder’ agent and unlikely to result in haematoma
formation, which may increase both the risk of infection and the
need for further surgery. Aspirin is also unlikely to result in persistent
wound drainage, which has been shown to be associated with the use
of agents such as low-molecular-weight heparin (LMWH) and other
more aggressive agents. The main objective of this review was to summarise the current
evidence relating to the efficacy of aspirin as a VTE prophylaxis
following arthroplasty, and to address some of the common questions
about its use. There is convincing evidence that, taking all factors into account,
aspirin is an effective, inexpensive, and safe form of VTE following
arthroplasty in patients without a major risk factor for VTE, such
as previous VTE. Cite this article: Bone Joint J 2017;99-B:1420–30.

Abstract
BACKGROUND Rates of venous thromboembolism in contemporary studies of primary total knee arthroplasty (TKA) have been reported to be as high as 3.5%. Although drug prophylaxis is effective, the best option among these regimens is not well established. The purpose of this study was to evaluate the comparative effectiveness and safety of aspirin, low-molecular-weight heparin, synthetic pentasaccharide factor Xa inhibitors, and vitamin K antagonist. METHODS Data were from a US total joint replacement registry, with 30,499 patients receiving unilateral TKA from May 16, 2006, to December 31, 2013. Patients received either aspirin (324-325 mg daily), enoxaparin (40-60 mg daily), fondaparinux (2.5 mg daily), or warfarin (all doses) and were followed up 90 days postoperatively on several outcomes: deep vein thrombosis, pulmonary embolism, major bleeding, wound complications, infection, and death. RESULTS There was no evidence that fondaparinux, enoxaparin, or warfarin were superior to aspirin in the prevention of pulmonary embolism, deep vein thrombosis, or venous thromboembolism or that aspirin was safer than these alternatives. However, enoxaparin was found to be as safe as aspirin with respect to bleeding, and fondaparinux was as safe as aspirin for risk of wound complications. CONCLUSION Among TKA patients, we did not find evidence for decreased effectiveness or increased safety with use of aspirin, but enoxaparin had comparable safety to aspirin for bleeding and fondaparinux had comparable safety to aspirin for wound complications.

Abstract
BACKGROUND The purpose of this study was to compare short-term side effects of aspirin (ASA) 325 mg vs ASA 81 mg orally twice daily (PO BID) when used as thromboembolic prophylaxis following primary total joint arthroplasty. METHODS A 1-year prospective cohort study was performed on 643 primary unilateral total joint arthroplasty patients operated on by a single surgeon. Two hundred eighty-two patients were administered ASA 325 mg PO BID and 361 patients were administered ASA 81 mg PO BID for 1 month. A questionnaire assessing the side effects of ASA intake was administered 1 month postoperatively. RESULTS The overall rate of gastrointestinal side effects (GI upset and nausea) was 1.9%, but ASA 325 mg had a higher rate 9/282 (3.2%) than ASA 81 mg 3/361 (0.8%), P = .04. Overall GI bleeding was 0.9%, with 2/282 (0.7%) in the ASA 325 mg group, vs 4/361 (1.1%) in the ASA 81 mg group, P = .70. One patient in the ASA 81 mg group (0.3%) developed a deep vein thrombosis. No patient developed pulmonary embolism, periprosthetic joint infection, tinnitus, wheezing and/or shortness of breath, chest pain, or headaches. In the ASA 325 mg group, 9/282 (3.2%) discontinued ASA and in the ASA 81 mg group, 8/361 (2.2%) discontinued ASA, P = .47. Four patients in the ASA 325 group (1.4%) changed to ASA 81 mg. CONCLUSION ASA 81 mg is associated with significantly less GI distress and nausea compared with ASA 325 mg. GI bleeding was equally prevalent between the 2 dosing regimens, so patients need to be informed of this risk regardless of the ASA dose.

Abstract
Optimal prophylaxis for prevention of venous thromboembolism (VTE) after total joint arthroplasty (TJA) remains debated. The purpose of this study was to compare postoperative complications in patients receiving different VTE chemoprophylactic regimens. Using a nationwide healthcare database, 72,670 THA patients without a history of VTE were identified. Study cohorts received VTE prophylaxis within 30 days postoperatively. Odds ratios and 95% confidence intervals were used to assess 30-day and 90-day postoperative complications (hematoma, hemorrhage, transfusion, pulmonary embolism (PE), VTE, prosthetic joint infection (PJI), and incision/drainage (I&D)). Of the 72,670 THA patients, 25,966 received single medication VTE prophylaxis; 551 (2.12%) aspirin, 6791 (26.15%) enoxaparin, 12,008 (46.25%) warfarin, 5403 (20.81%) rivaroxaban, 876 (3.37%) fondaparinux and 337 (1.30%) apixaban. 30-day complications included; aspirin: I&D; warfarin: I&D, hematoma, hemorrhage, transfusion, PJI, PE and DVT; apixaban: hematoma and hemorrhage. 90-day complications included; aspirin: I&D; warfarin: I&D, hematoma, hemorrhage, transfusion, PJI, PE and DVT. Warfarin was the only anticoagulant associated with a higher risk for DVT, and the highest risk for 30-day and 90-day complications. Aspirin had the highest risk for I&D. Despite three times increased 30-day risk for bleeding, apixaban was effective in preventing VTE during the high-risk 3-month-period. Enoxaparin had the lowest risk for PE and DVT while rivaroxaban had the lowest risk for PJI, hematoma, I&D, hemorrhage and transfusion.

Patient and Perioperative Variables Affecting 30-Day Readmission for Surgical Complications After Hip and Knee Arthroplasties: A Matched Cohort Study. J Arthroplasty 2017; 32:1074-1079. [PMID: 27876255 DOI: 10.1016/j.arth.2016.10.019] [Citation(s) in RCA: 61] [Impact Index Per Article: 8.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2016] [Revised: 10/08/2016] [Accepted: 10/13/2016] [Indexed: 02/01/2023] Open
Abstract
BACKGROUND Changes in reimbursement for total hip and knee arthroplasties (THA and TKA) have placed increased financial burden of early readmission on hospitals and surgeons. Our purpose was to characterize factors of 30-day readmission for surgical complications after THA and TKA at a single, high-volume orthopedic specialty hospital. METHODS Patients with a diagnosis of osteoarthritis and who were readmitted within 30 days of their unilateral primary THA or TKA procedure between 2010 and 2014. Readmitted patients were matched to nonreadmitted patients 1:2. Patient and perioperative variables were collected for both cohorts. A conditional logistic regression was performed to assess both the patient and perioperative factors and their predictive value toward 30-day readmission. RESULTS Twenty-one thousand eight hundred sixty-four arthroplasties (THA = 11,105; TKA = 10,759) were performed between 2010 and 2014 at our institution, in which 60 patients (THA = 37, TKA = 23) were readmitted during this 5-year period. The most common reasons for readmission were fracture (N = 14), infection (N = 14), and dislocation (N = 9). Thirty-day readmission for THA was associated with increased procedure time (P = .05), length of stay (LOS) shorter than 2 days (P = .04), discharge to a skilled nursing facility (P = .05), and anticoagulation use other than aspirin (P = .02). Thirty-day readmission for TKA was associated with increased tourniquet time (P = .02), LOS <3 days (P < .01), and preoperative depression (P = .02). In the combined THA/TKA model, a diagnosis of depression increased 30-day readmission (odds ratio 3.5 [1.4-8.5]; P < .01). CONCLUSION Risk factors for 30-day readmission for surgical complications included short LOS, discharge destination, increased procedure/tourniquet time, potent anticoagulation use, and preoperative diagnosis of depression. A focus on risk factor modification and improved risk stratification models are necessary to optimize patient care using readmission rates as a quality benchmark.

Abstract
BACKGROUND There is an increasing interest in outpatient total hip arthroplasty (THA), as there are perceived benefits to the patient, insurer, and overall healthcare system. However, the safety of outpatient total joint arthroplasty has not been studied. METHODS Five hundred forty-nine patients who underwent mini-posterior THA at a freestanding independent ambulatory surgical center (ASC) were reviewed. All patients were discharged to home on the day of surgery. RESULTS The average age of the patients was 54.4 years (range 27-73). The average American Society of Anesthesiologists score was 1.6 (range 1-3). Of the 549 patients, 3 (0.5%) admitted from the surgery center to our local hospital. One patient was admitted for pain control after failing to disclose his long-term high-dose narcotic dependence, one patient was admitted for an acetabular component migration identified on postoperative x-ray, and one patient was admitted for hypotension, bradycardia, and an acute polyarthralgia exacerbation. An additional patient was seen 2 days after surgery in a local emergency department for oversedation secondary to narcotics and later discharged to home. CONCLUSION Outpatient THA at an ASC is safe and effective when performed on the appropriately indicated patient. There were 4 visits to the hospital within 2 days of surgery. Only 1 was related to medical events, 2 were pain control and/or medication-related and the final was technique-related. Known orthopedic complications including infection, dislocation, and deep vein thrombosis appear consistent with the literature for a series of this size. Same day discharge THA in an ASC is safe and reproducible.

Abstract
BACKGROUND Aspirin is a safe and effective prophylaxis for the prevention of venous thromboembolism following total joint arthroplasty. The optimal dose of aspirin prophylaxis is unknown. Our hypothesis was that lower-dose aspirin is as effective as higher-dose aspirin for the prevention of venous thromboembolism and is associated with fewer gastrointestinal side effects. METHODS In a prospective, crossover study, we analyzed 4,651 primary total joint arthroplasty cases performed from July 2013 to June 2015. For 4 weeks, 3,192 patients received enteric-coated 325-mg aspirin twice daily (the 325-mg aspirin group) and 1,459 patients received 81-mg aspirin twice daily (the 81-mg aspirin group). There were no significant differences (p > 0.05) in sex, body mass index, or Charlson Comorbidity Index between the two patient populations. Recorded complications occurring within 90 days postoperatively included symptomatic venous thromboembolism (deep venous thrombosis and pulmonary embolism), gastrointestinal complications, acute periprosthetic joint infection, and death. RESULTS The incidence of venous thromboembolism of 0.1% (95% confidence interval [CI], 0% to 0.3%) in the 81-mg aspirin group (1 with deep venous thrombosis and 1 with pulmonary embolism) was not significantly different (p = 0.345) from 0.3% (95% CI, 0.1% to 0.6%) in the 325-mg aspirin group (7 with deep venous thrombosis and 5 with pulmonary embolism). The incidence of gastrointestinal bleeding or ulceration of 0.3% (95% CI, 0% to 0.5%) in the 81-mg aspirin group was slightly, but not significantly (p = 0.66), lower than the 0.4% (95% CI, 0.2% to 0.6%) in the 325-mg aspirin group. The incidence of acute periprosthetic joint infection was 0.2% (95% CI, 0% to 0.4%) in the 81-mg aspirin group compared with 0.5% (95% CI, 0.2% to 0.7%) in the 325-mg aspirin group (p = 0.28). The 90-day mortality rate was similar in both groups at 0.1% (95% CI, 0% to 0.2%) in the 81-mg aspirin group and 0.1% (95% CI, 0% to 0.2%) in the 325-mg aspirin group (p = 0.78). CONCLUSIONS Our study demonstrates that low-dose aspirin is not inferior to high-dose aspirin for venous thromboembolism prophylaxis following total joint arthroplasty. This is not unexpected, as the available literature demonstrates that low-dose aspirin is as effective as higher-dose aspirin in the prevention of acute coronary syndrome and cerebrovascular events.

Abstract
BACKGROUND Venous thromboembolism (VTE) comprises pulmonary embolism and deep vein thrombosis and is a complication of particular concern in lower limb arthroplasty. In recent years, aspirin has emerged as a potential alternative thromboprophylactic agent, particularly after its acceptance as a recommended agent by the American College of Chest Physicians. Aspirin is favorable due to its relative cost-effectiveness and convenience compared to novel oral anticoagulants and warfarin. However, its efficacy since its inclusion in the American College of Chest Physicians guidelines remains unclear. The present systematic review aimed to establish the efficacy of aspirin in preventing VTE in total hip and knee arthroplasty. METHODS Electronic searches were performed using 6 databases from up to June 2015, identifying all relevant studies. Data were extracted and meta-analyzed. RESULTS Eleven relevant studies were identified for inclusion in the present meta-analysis. The overall rate of deep vein thrombosis and pulmonary embolism in both hip and knee arthroplasty was 1.2% and 0.6%, respectively. The rate of major bleeding was 0.3%. Pooled mortality rate was 0.2%. All findings demonstrated a high and significant degree of heterogeneity. CONCLUSION Aspirin, both alone and in multimodal approaches to thromboprophylaxis, confers a low rate of VTE, with a low risk of major bleeding complications. However, the evidence for its use is limited by the low quality of studies and variation in dose in dosing regimes. Future randomized controlled trials should investigate the efficacy of aspirin, as well as the ideal dosing protocol for its use in thromboprophylaxis in arthroplasty.

Abstract
BACKGROUND Prior to 2012, the American Academy of Orthopaedic Surgeons (AAOS) and American College of Chest Physicians (ACCP) differed in their recommendations for postoperative pharmacologic venous thromboembolism prophylaxis (VTEP) after total joint arthroplasty. More specifically, aspirin (ASA) monotherapy was not endorsed by the ACCP as an acceptable prophylaxis. In 2012, the ACCP supported ASA monotherapy compared with no prophylaxis. Our aim was to investigate the impact of the convergence of ACCP and AAOS recommendations on surgeon prescribing patterns after knee arthroplasty (KA). METHODS This is a retrospective chart review. We collected data to assess preoperative VTE risk and examined VTEP prescriptions on postoperative day 1 (POD1) and at discharge (D/C) from 7/2008 to 12/2011 (pre-period) and 1/2012 to 7/2014 (post-period). Adult patients undergoing primary and revision KA were identified by ICD-9 procedure codes. Patients on preoperative full-dose anticoagulation and with hypercoagulability disorders were excluded. RESULTS Of 368 records reviewed, 329 were included in the analysis. There were no differences between the two period groups for age, sex, BMI, estrogen therapy, malignancy, smoking status, prior VTE, bilateral procedures, or surgery within 3 months. On POD1, in the pre-period, 4.6 % were prescribed ASA monotherapy versus 44.4 % in the post-period (p < 0.001). On D/C, in the pre-period, 13.9 % were prescribed ASA versus 55.6 % in the post-period (p < 0.001). CONCLUSIONS Our results indicate a statistically significant change in orthopedist prescribing patterns after guideline convergence. Furthermore, there was no apparent change in VTE risk between the two study groups when excluding patients necessitating full anticoagulation. Prior literature has shown that the divergence in guidelines influenced physicians away from ASA and toward more potent anticoagulants in order to avoid potential litigation. Once its role in VTEP was supported by the ACCP, it appears that ASA monotherapy was readily and rapidly incorporated into clinical practice. ASA may be favored over other VTEP agents for its lower bleeding risk profile and cost. This study highlights the profound impact clinical practice guidelines have on clinician prescribing patterns. Although prospective randomized trials are needed to compare the efficacy of ASA with other VTEP agents, ASA is now a predominant part of the VTEP armamentarium after KA.

Abstract
As health care reforms continue to improve quality of care, significant emphasis will be placed on evaluation of orthopedic patient outcomes. Total joint arthroplasty (TJA) has a proven track record of enhancing patient quality of life and are easily replicable. The outcomes of these procedures serve as a measure of health care initiative success. Specifically, length of stay, will be targeted as a marker of quality of surgical care delivered to TJA patients. Within this review, we will discuss preoperative and postoperative methods by which orthopedic surgeons may enhance TJA outcomes and effectively reduce length of stay.

Aspirin Is as Effective as and Safer Than Warfarin for Patients at Higher Risk of Venous Thromboembolism Undergoing Total Joint Arthroplasty. J Arthroplasty 2016; 31:83-6.

Abstract
BACKGROUND There is continued controversy regarding the optimal venous thromboembolism (VTE) prophylaxis, particularly for total joint arthroplasty (TJA) patients at higher risk. The purpose of this study was to compare the efficacy of aspirin (ASA) to warfarin in patients with higher risk of VTE. METHODS This retrospective study examined 30,270 patients who received ASA or warfarin for VTE prophylaxis after TJA. Using a previously developed risk stratification model, patients were classified into low or high VTE risk categories. Postoperative 90-day VTE, periprosthetic joint infection (PJI), gastrointestinal complications, and mortality were recorded. RESULTS The incidences of VTE, PJI, and mortality were higher in patients receiving warfarin compared to ASA. In multivariate analysis, warfarin was an independent risk factor for VTE, PJI, and mortality in the higher risk VTE patients (P < .001). There was no significant difference in gastrointestinal complications between groups. CONCLUSION Our study demonstrates that ASA is as effective as and safer than warfarin for VTE prophylaxis after TJA, even in patients at higher risk of VTE.

Abstract
BACKGROUND Venous thromboembolism (VTE) after total joint arthroplasty (TJA) is a potentially fatal complication. Currently, a standard protocol for postoperative VTE prophylaxis is used that makes little distinction between patients at varying risks of VTE. We sought to develop a simple scoring system identifying patients at higher risk for VTE in whom more potent anticoagulation may need to be administered. METHODS Utilizing the National Inpatient Sample data, 1,721,806 patients undergoing TJA were identified, among whom 15,775 (0.9%) developed VTE after index arthroplasty. Among the cohort, all known potential risk factors for VTE were assessed. An initial logistic regression model using potential predictors for VTE was performed. Predictors with little contribution or poor predictive power were pruned from the data, and the model was refit. RESULTS After pruning of variables that had little to no contribution to VTE risk, using the logistic regression, all independent predictors of VTE after TJA were identified in the data. Relative weights for each factor were determined. Hypercoagulability, metastatic cancer, stroke, sepsis, and chronic obstructive pulmonary disease had some of the highest points. Patients with any of these conditions had risk for postoperative VTE that exceeded the 3% rate. Based on the model, an iOS (iPhone operating system) application was developed (VTEstimator) that could be used to assign patients into low or high risk for VTE after TJA. CONCLUSION We believe individualization of VTE prophylaxis after TJA can improve the efficacy of preventing VTE while minimizing untoward risks associated with the administration of anticoagulation.

Abstract
BACKGROUND Little is known about total joint arthroplasty (TJA) outcomes in gout patients. The purpose of this study was to compare adverse events between gout and nongout patients who underwent primary TJA. METHODS Using our institutional database and medical records review, a retrospective case-control study was conducted. From 2000 to 2012, a total of 482 gout TJA patients were matched with nongout TJA patients in a 1:1 ratio. Length of stay, complications, 90-day emergency room visits, and 90-day readmissions in these patients were compared. RESULTS Gout patients had greater wound healing problems (12.2% vs 5.0%, P = .001) and renal complications (8.9% vs 3.1%, P = .0003) compared with nongout patients. There were no significant differences between gout and nongout patients in terms of mean length of hospital stay (3.82 vs 3.17 days, P = .11) and 90-day emergency room visits (5.6% vs 3.5%, P = 1.00). Subgroup analysis showed that 90-day readmission rates were higher in gout patients who underwent total hip arthroplasty compared with those in nongout THA patients (6.8% vs 2.1%, P = .02). CONCLUSION Gout patients undergoing TJA have greater wound healing problems and renal complications. Surgeons should be cognizant of fluid management, renal monitoring and wound issues and should be cautious when treating TJA gout patients.

Abstract
The routine use of venous thromboembolism prophylaxis in patients undergoing foot and ankle procedures is not well supported in the literature. Multiple studies draw conclusions from heterogeneous populations, and specific studies have small numbers of specific pathologic conditions. Depending on the study, recommendations for and against venous thromboembolism prophylaxis in foot and ankle surgery can be made. The identification of risk factors for venous thromboembolism is paramount in the decision making of postoperative venous thromboembolism prophylaxis.

Abstract
As a result of reading this article, physicians should be able to: 1. State an argument for, and background information on, patient-centered arthroplasty protocols. 2. Describe specific recommendations for designing a simplified arthroplasty care pathway that is reproducible in other institutions. 3. Discuss cost-effectiveness research on the latest value-delivering protocols. 4. Recognize areas of continued research and opportunities for future improvement in protocol development. Total joint arthroplasty is a successful orthopedic procedure that is performed in high volume in the United States and internationally. As economic pressures continue to mount in the US health care system, it will become increasingly important to minimize cost and improve quality and value. At the authors' institution, a protocol-based arthroplasty model is used, in many ways based on simplification of the patient care pathway. The largely evidence-based protocol has its foundation in eliminating unnecessary dogmatic practices, enhancing the patient experience, and achieving cost-effectiveness. The authors believe that a model like this can be applied to joint arthroplasty practices across the country in the future to maximize the value delivered to patients.

Abstract
Interest in aspirin as an alternative strategy for venous thromboembolism prophylaxis after arthroplasty has grown, as studies have suggested improved clinical efficacy and lower complication rates with aspirin compared to warfarin. The goal of this study was to compare the direct costs of an episode of arthroplasty care, when using aspirin instead of warfarin. The charts of patients who either received aspirin or warfarin after arthroplasty from January 2008 to March 2010 were retrospectively reviewed. Charges were recorded for their index admission, and for subsequent admissions related to either VTE or complications of prophylaxis. Multivariate analysis revealed that aspirin was an independent predictor of decreased cost of index hospitalization, and total episode of care charges, achieved largely through a shorter length of hospitalization.

Abstract
The efficacy and safety of aspirin (ASA) for prevention of venous thromboembolism (VTE) following total joint arthroplasty (TJA) have been demonstrated. Our hypothesis was that postoperative ASA compared to warfarin lowers the incidence of periprosthetic joint infection (PJI). Between January 2006 and December 2012, 1456 patients received ASA and 1700 patients received warfarin following primary TJA as standard VTE prophylaxis. Logistic regression was utilized to identify independent risk factors of PJI. Incidence of PJI was significantly lower at 0.4% in patients receiving ASA vs. 1.5% in patients receiving warfarin (P<0.001). Warfarin and elevated BMI were independent risk factors for PJI following TJA (P<0.05). Our research suggests that the use of ASA compared to warfarin for VTE prophylaxis reduces the risk of PJI following TJA.

Abstract
Context: Venous thromboembolic (VTE) disease is thought to be an uncommon but serious problem after anterior cruciate ligament (ACL) reconstruction. Rates of VTE after ACL reconstruction are not well documented. Objective: To determine the rates of deep vein thrombosis (DVT) and symptomatic pulmonary emboli (PE) after ACL reconstruction. Data Sources: Five publicly available databases (PubMed, Cochrane Database of Systematic Reviews, Scopus, Embase, and CINAHL Complete) were utilized. Study Selection: All studies that screened patients for DVT and reported rates of DVT and PE after ACL reconstruction were eligible for inclusion. Level 5 evidence, cadaver, biomechanical, and basic science studies; studies reporting only multiligament reconstruction outcomes; studies where rates of DVT and PE could not be separated out from patients undergoing other types of arthroscopic knee procedures; and classification studies were excluded. Study Design: Systematic review. Level of Evidence: Level 4. Data Extraction: All study, subject, and surgical data were analyzed. Descriptive statistics were calculated. Results: Six studies met the inclusion criteria, with a mean Modified Colman Methodology Score of 30 ± 8.22. A total of 692 patients (488 men [70.5%]; mean age, 31.6 ± 2.82 years; mean follow-up, 7 ± 18.4 months) underwent ACL reconstruction using either semitendinosus-gracilis autograft (77.6%), bone–patellar tendon–bone (BTB) autograft (22%), or allograft (0.4%). No patient received postoperative pharmacological anticoagulation. Fifty-eight patients (8.4%) had a DVT (81% below knee and 19% above knee), while only 1 patient (0.2%) had a symptomatic PE. When reported, 27% of DVT episodes were symptomatic. Conclusion: The rate of DVT after ACL reconstruction in patients who did not receive postoperative pharmacological anticoagulation is 8.4%, while the rate of symptomatic PE is 0.2%. Of the DVT episodes that occurred, 73% were asymptomatic.

Abstract
BACKGROUND When contemplating thromboprophylaxis for patients undergoing elective foot and ankle surgery the potential for complications secondary to venous thromboembolism (VTE) must be balanced against the cost, risk, and effectiveness of prophylactic treatment. The incidence of pulmonary embolism (PE) following foot and ankle surgery is considerably lower than after hip or knee surgery. The purpose of this study was to assess current trends in practice regarding VTE prophylaxis among expert orthopaedic foot and ankle surgeons. METHODS An e-mail-based survey of active AOFAS (American Orthopaedic Foot and Ankle Society) committee members was conducted (n = 100). Surgeons were questioned as to their use, type, and duration of thromboprophylaxis following elective ankle fusion surgery. Scenarios included the following: (1) A 50-year-old woman with no risk factors; (2) a 50-year-old woman with a history of PE; and (3) a 35-year-old woman actively using birth control pills (BCPs). RESULTS The response rate for the survey was 80% (80/100). Replies regarding the use of thromboprophylaxis were as follows: (1) in the absence of risk factors, 57% of respondents (45/80) answered, "No prophylaxis required"; (2) for the scenario in which the patient had experienced a previous PE, 97.5% of respondents (78/80) answered, "Yes" to prophylaxis use; (3) for the scenario in which the patient was on BCP, 61.3% of respondents (49/80) stated that they would give some type of thromboprophylaxis. The most commonly recommended methods of prophylaxis were aspirin, 49% (24/49), and low-molecular-weight heparin, 47% (23/49). The recommended length of time for thromboprophylaxis varied widely, from 1 day to more than 6 weeks. CONCLUSION . There remains wide variation in the practice of deep-vein thrombosis thromboprophylaxis within the foot and ankle community. Because risks for foot and ankle patients differ from those in the well-studied areas of hip and knee, specific guidelines are needed for foot and ankle surgery. LEVELS OF EVIDENCE Level V: Expert Opinion.

Cost-effective prophylaxis against venous thromboembolism after total joint arthroplasty: warfarin versus aspirin. J Arthroplasty 2015; 30:159-64. [PMID: 25534862 DOI: 10.1016/j.arth.2014.08.018] [Citation(s) in RCA: 41] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/11/2014] [Accepted: 08/27/2014] [Indexed: 02/01/2023] Open
Abstract
Although recent guidelines suggest aspirin for venous thromboembolism (VTE) prophylaxis in low risk patients following total hip arthroplasty (THA) and total knee arthroplasty (TKA), there are no cost-effectiveness studies comparing aspirin and warfarin. In a Markov cohort cost-effectiveness analysis, we found that aspirin cost less and saved more quality-adjusted life-years (QALYs) than warfarin in all age groups. Cost per QALY gained by aspirin was $24,506.20 at age of 55 and $47,148.10 at the age of 85 following THA and $15,117.20 and $24,458.10 after TKA, which were greater than warfarin. In patients undergoing THA/TKA without prior VTE, aspirin is more cost-effective prophylactic agent than warfarin. Warfarin might be a better prophylaxis in TKA patients with high probability of VTE and very low probability of bleeding.

Abstract
Whereas aspirin is recommended and widely used to prevent arterial thrombosis, its role in the prevention of deep venous thrombosis is not well defined. Aspirin is well accepted, easy to manage with few risks and low cost, and thus ideal for thromboprophylaxis if evidence shows it is effective. Recent guidelines and large studies were reviewed. Recent guidelines include aspirin as an acceptable thromboprophylactic agent after hip and knee orthopedic surgery despite continued publication of underpowered and contradictory studies. Two large randomized controlled trials pooled together suggest that low-dose (100 mg) aspirin is a reasonable alternative to prevent recurrence of venous thromboembolism (VTE) in patients who have been treated for a first episode of unprovoked VTE. We suggest that the current practice using aspirin to prevent thromboembolism include cautious discussion of the benefits and risks of this agent before use in a patient until precise clarification of dosage and treatment length is available. Despite inclusion of aspirin in the guidelines for orthopedic surgery, there is little evidence to support its use for primary prevention of VTE. Until definitive unbiased trials are published, we suggest that aspirin remain a realistic option to use for secondary prevention of VTE, especially compared with the option of using no prophylaxis.
