Abstract
BACKGROUND To confirm the diagnosis of periprosthetic joint infection (PJI), the Infectious Diseases Society of America (IDSA) and the International Consensus Meeting (ICM) have defined criteria that include histology as a minor criterion and the sonication method only as an additional criterion. The aim of this monocentric, retrospective study was to investigate the value of histology and whether sonication leads to a more accurate diagnosis. MATERIALS AND METHODS All revision surgeries for knee and hip arthroplasty between 2017 and 2020 were included. With regard to microbiological diagnostic, conventional culture of periprosthetic biopsies and sonication of explant material were performed. In addition, histology and non-specific inflammatory markers (CRP, leukocytes) were recorded. RESULTS A total of 78 patients with PJI and 62 aseptic controls were included. From both microbiological methods (conventional culture / sonication), Staphyloccus (S.) epidermidis and S. aureus were detected most frequently. However, compared to the conventional microbiology, a higher sensitivity was calculated for sonication, albeit with a lower specificity in relation to a PJI. In two logistic regression models for the significance of all diagnostic parameters in PJI, the AUC was 0.92 and 0.96 with histology in particular making the decisive contribution in both models (p < 0. 001, both models). CONCLUSION Since histology showed the highest accuracy in the current study, its importance in the PJI criteria should be reevaluated. Sonication shows a high sensitivity for germ detection with a lower specificity and should only be used in combination with the conventional culture for microbiolgical diagnostics.

Abstract
INTRODUCTION Tobacco use elevates the incidence of postoperative complications and remains a key modifiable risk factor of perioperative surgical optimization. It remains unclear whether non-tobacco nicotine dependence confers an increased risk of surgical complications. This study evaluates postoperative complications in patients with non-tobacco nicotine dependence for total knee arthroplasty (TKA). METHODS We queried the TriNetX health database using Current Procedural Terminology and International Classification of Diseases, 10th Revision (ICD-10) codes and identified two cohorts for evaluation. Cohort A was defined as patients who had a TKA; had a dependence on nicotine; did not have nicotine dependence to cigarettes, chewing tobacco, other tobacco products; and were between the ages of 35 and 90 years. Cohort B was defined as patients who had a TKA but did not have a dependence on nicotine or a personal history of nicotine dependence and were between the ages of 35 and 90 years. RESULTS This study analyzed a total of 10,594 non-tobacco nicotine-dependent patients and 175,079 non-dependent patients who underwent TKA. In the analysis of propensity-matched cohorts, non-tobacco nicotine-dependent patients demonstrated an increased rate of various postoperative complications within 90 days. Dependent patients saw a significantly increased risk of infection after a procedure (P < 0.001), deep vein thrombosis (P < 0.001), pulmonary embolism (P < 0.001), sepsis (P = 0.0065), and prosthetic joint infection (P = 0.0361) and a higher 3-year revision rate (P = 0.0084). DISCUSSION Non-tobacco nicotine dependence demonstrated an increased associated risk of postoperative surgical complications for patients undergoing TKA. Orthopaedic surgeons should consider evaluating non-tobacco nicotine dependence within their surgical optimization protocol. LEVEL OF EVIDENCE Level III, Prognostic.

Abstract
Orthopedic surgical patients who use nicotine are at a high risk for postoperative complications including infection, respiratory failure, cardiac arrest, and death. Periprosthetic joint infections may result from nicotine-induced immunosuppression and microvascular changes, increasing perioperative morbidity and mortality. These complications result in higher health care costs, increased length of stay, and loss of reimbursement due to readmissions. Four weeks of nicotine cessation prior to arthroplasty decreases these risks; however, perioperative teams may lack reliable nicotine screening and cessation education methods. This project identified inconsistencies in nicotine screening and cessation counseling in the preoperative setting, which contributed to surgery cancellations among patients who required to demonstrate nicotine cessation preoperatively. Standardization of preoperative nicotine screening and patient cessation education resources can improve the identification of orthopedic patients who use nicotine and provide concrete, proven methods of achieving nicotine cessation prior to elective primary arthroplasty. Investment from perioperative staff is essential to ensure success.

Abstract
BACKGROUND Prior studies suggest that distressed patients or those who have poor mental health have inferior postoperative outcomes when compared to nondistressed patients. However, these studies typically do not account for substance use or other comorbidities often found in this population, which can independently contribute to postoperative complications. This study sought to control for these factors and assess if a diagnosis of a mental health condition is directly associated with worse outcomes after total joint arthroplasty. METHODS A retrospective chart review was performed for 3,182 patients who underwent a total hip arthroplasty and 4,430 patients who underwent a total knee arthroplasty. Diagnosis of the mental health disorders included depression, anxiety disorder, adjustment disorder, bipolar disorder, trauma, stressor-related disorder, and schizophrenia or schizoaffective disorder. Multivariable analyses were performed to control for alcohol use, drug use, tobacco use, body mass index, and a comorbidity index. RESULTS When controlling for body mass index and Charlson comorbidity index, no statistically significant associations were found between a diagnosis of any mental health condition or a specific diagnosis of depression or anxiety, and 90-day readmission, reoperation, or 1 year mortality for patients undergoing total knee arthroplasty or total hip arthroplasty. CONCLUSIONS When accounting for confounding factors, there does not appear to be a direct association between diagnosis of any of the psychiatric conditions we studied and outcomes after primary total joint arthroplasty. While prior studies suggest addressing the mental health condition may improve outcomes, this study suggests that preoperative medical optimization and potentially addressing substance use may be more effective strategies.

Abstract
BACKGROUND AND PURPOSE Patients actively smoking at the time of primary hip or knee arthroplasty are at increased risk of direct perioperative complications. We investigated the association between smoking status and risk of revision and mortality within 2 years following hip or knee arthroplasty. METHODS We used prospectively collected data from the Dutch Arthroplasty Register. All primary total hip arthroplasties (THAs), total knee arthroplasties (TKAs), and unicondylar knee arthroplasties (UKAs) with > 2 years' follow-up were included (THA: n = 140,336; TKA: n = 117,497; UKA: n = 14,807). We performed multivariable Cox regression analyses to calculate hazard risks for differences between smokers and non-smokers, while adjusting for confounders (aHR). RESULTS The smoking group had higher risk of revision (THA: aHR 1.3, 95% confidence interval [CI] 1.1-1.4 and TKA: aHR 1.4, CI 1.3-1.6) and risk of mortality (THA: aHR 1.4, CI 1.3-1.6 and TKA: aHR 1.4, CI 1.2-1.6). Following UKA, smokers had a higher risk of mortality (aHR 1.7, CI 1.0-2.8), but no differences in risk of revision were observed. The smoking group had a higher risk of revision for infection following TKA (aHR 1.3, CI 1.0-1.6), but not following THA (aHR 1.0, CI 0.8-1.2). CONCLUSION This study showed that the risk of revision and mortality is higher for smokers than for non-smokers in the first 2 years following THA and TKA. Smoking could contribute to complications following primary hip or knee arthroplasty.

Abstract
INTRODUCTION Neuromodulation represents one of the more advanced tools in the armamentarium of pain physicians. To optimize neuromodulation patient selection and management, an institutional interdisciplinary neuromodulation committee was created at each of two academic medical centers (University of California Davis [UCD] and Stanford University). The committee aims to collaboratively optimize neuromodulation candidates, to assess and minimize medical and psychologic risks, and to select the best device given a patient's pain condition. In this study, we present the methods and outcome data of the Neuromodulation Committee at the two institutions. MATERIALS AND METHODS After institutional review board approval, we included all adult patients who were evaluated by the Neuromodulation Committee between 2017 and 2020 at two academic pain clinics. Patients with insufficient data were excluded from the study. A retrospective chart review was completed on 385 UCD and Stanford University patient committee reviews. Data collected from the chart review included demographics (age, sex), committee meeting results (proceed with trial/implant or decline), trial success, and implant rate. RESULTS Of the 385 patients screened, the committees recommended proceeding with an implantable device (peripheral and neuraxial) in 337 patients (87.5%). Of the 278 patients recommended for neuraxial neuromodulation, 131 underwent trials with percutaneous leads (47.1%). Trials were successful (causing a ≥50% reduction in self-reported pain or improved function) in 108 patients (82.4%). The institutions completed 87 implants of 131 trials, representing a trial-to-permanent ratio of 66.4%. CONCLUSIONS The Neuromodulation Committee aims to identify optimal patients for neuromodulation, address procedural challenges, decrease adverse events, provide educational context for trainees, and improve patient-related outcomes. Patients who were recommended for neuromodulation and subsequently underwent intervention had high trial success rates for dorsal root ganglion stimulation and spinal cord stimulation. The findings indicate that such an approach can lead to neuromodulation success, especially at academic centers, by combining the expertise of both medical and psychologic professionals.

Abstract
The meta-analysis aims to assess and compare the effect of tobacco usage on surgical site wound problems (SSWPs) after primary total hip and total knee arthroplasty (PTH&TKA). Using dichotomous random- or fixed-effects models, the outcomes of this meta-analysis were examined, and the odds ratio (OR) with 95% confidence intervals (CIs) was computed. Fifteen studies from 2001 to 2023 were enrolled for the present meta-analysis including 560 819 personals with PTH&TKA. Smokers had significantly higher SSWPs (OR, 1.53; 95% CI, 1.21-1.94, p < 0.001) compared with non-smokers in personals with PTH&TKA. Current smokers had significantly higher SSWPs (OR, 1.59; 95% CI, 1.40-1.80, p < 0.001) compared with non-smokers in personals with PTH&TKA. Current smokers had significantly higher SSWPs (OR, 1.42; 95% CI, 1.19-1.70, p < 0.001) compared with former smokers in personals with PTH&TKA. However, former smokers and non-smokers had no significant difference in SSWPs (OR, 1.11; 95% CI, 0.95-1.30, p = 19) in personals with PTH&TKA. The examined data revealed that in personals with PTH&TKA smokers had significantly higher SSWPs compared with non-smokers, and current smokers had significantly higher SSWPs compared with non-smokers and former smokers; however, former smokers and non-smokers had no significant difference in SSWPs. Yet, attention should be implemented while relating to its values since some of the comparisons were made using a low number of selected studies.

Abstract
BACKGROUND Studies suggest an increase in the number of combined users of tobacco and cannabis. Therefore, we specifically assessed tobacco, cannabis, and combined users who underwent primary total knee arthroplasty (TKA) to determine 90-day to 2-year: (1) odds of periprosthetic joint infection; (2) odds of revision; and (3) medical complications. METHODS We queried a national, all payer database of patients undergoing primary TKA between 2010 and 2020. Patients were stratified according to current use of tobacco products (n = 30,000), cannabis (n = 400), or a combination (n = 3,526). These were defined according to International Classification of Disease codes, Ninth and Tenth Editions. Patients were tracked from the 2 years before TKA through 2 years afterwards. A fourth group of TKA recipients who did not have tobacco nor cannabis use was used as a matching cohort. Periprosthetic joint infections (PJIs), revisions, and other medical/surgical complications from 90 days through 2 years were evaluated between these cohorts using bivariate analyses. Multivariate analyses assessed independent risk factors for PJI at 90 days through 2 years, adjusted for patient demographics and health metrics. RESULTS Combined tobacco and cannabis use were associated with the highest rates of PJI following TKA. The odds of 90-day PJI risk among cannabis, tobacco, and combined users was 1.60, 2.14, and 3.39, respectively, as compared to the matched cohort (P < .001). Co-users had the highest and significantly increased revision odds at 2 years following TKA (odds ratio = 1.52, 95% confidence interval, 1.15 to 2.00). At 1 and 2 years following TKA, cannabis, tobacco, and co-users had higher rates of myocardial infarctions, respiratory failures, surgical site infections, and manipulations under anesthesia when compared to the matched cohort (all P < .001). CONCLUSION Tobacco and cannabis use before primary TKA demonstrated a synergistic association on PJI risk from 90 days through 2 years. Although the harms of tobacco use are well-known, this additional knowledge about cannabis should be incorporated in the shared decision-making discussions in the pre-operative setting to best prepare for expected risks following primary TKA.

Abstract
STUDY DESIGN Retrospective study. OBJECTIVE This study evaluated the impact of chewing tobacco on both medical and spine-related complication rates after spinal lumbar fusions in comparison to both a control cohort and a smoking cohort. SUMMARY OF BACKGROUND DATA Smoking is a prevalent modifiable risk factor that has been demonstrated to be associated with increased complications after lumbar fusion. Although smoking rates have decreased in the United States, chewing tobacco use has not similarly reduced. Despite chewing tobacco delivering up to 4 times the dose of smoking, the impact of chewing tobacco is incompletely understood. METHODS A retrospective cohort study was conducted using the PearlDiver database. Patients who underwent lumbar spine fusion and used chewing tobacco were matched with a control cohort and a smoking cohort. Medical complications within 90 days after primary lumbar fusion were evaluated, including deep venous thrombosis, acute kidney injury, pulmonary embolism, transfusion, acute myocardial infarction, and inpatient readmission. Spine-related complications were evaluated at 2 years postoperatively, including pseudoarthrosis, incision and drainage (I&D), instrument failure, revision, and infection. RESULTS After primary lumbar fusion, the chewing tobacco cohort demonstrated significantly higher rates of pseudoarthrosis [odds ratio (OR): 1.41], revision (OR: 1.57), and any spine-related complication (OR: 1.32) compared with controls. The smoking cohort demonstrated significantly higher rates of pseudoarthrosis (OR: 1.88), I&D (OR: 1.27), instrument failure (OR: 1.39), revision (OR: 1.54), infection (OR: 1.34), and any spine-related complication (OR: 1.77) compared with controls. The chewing tobacco cohort demonstrated significantly lower rates of pseudoarthrosis (OR: 0.84), I&D (OR: 0.49), infection (OR: 0.70), and any spine-related complication (OR: 0.81) compared with the smoking cohort. CONCLUSIONS This study demonstrated that chewing tobacco is associated with higher rates of both spine-related and medical complications after primary lumbar fusion. However, chewing tobacco use is associated with less risk of complications compared with smoking. LEVEL OF EVIDENCE Level III.

[PMID: 36731583 DOI: 10.1016/j.arth.2023.01.035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/18/2022] [Revised: 01/20/2023] [Accepted: 01/23/2023] [Indexed: 02/04/2023] Open
Abstract
BACKGROUND Studies have demonstrated increased complication risk after total knee arthroplasty (TKA) in patients who smoke cigarettes, but it is unclear if smokeless tobacco use confers a similar impact. The purpose of this study was to (1) evaluate rates of postoperative complications after TKA in smokeless tobacco users and smokers as compared to matched controls, and (2) compare rates of postoperative complications in smokeless tobacco users versus smokers to determine if one is associated with significantly higher rates of postoperative complications. METHODS A retrospective cohort study was conducted using a national database. For patients who underwent primary TKA, smokeless tobacco users (n = 1,535) and smokers (n = 28,953) were matched at a 1:4 with controls (n = 6,140 and 115,812, respectively), and smokeless tobacco users (n = 1,481) were matched at a 1:4 with smokers (n = 5,924). Rates of joint complications within 2 years and medical complications within 90 days postoperatively were compared using multivariable logistic regressions. RESULTS After primary TKA, compared to controls, smokeless tobacco users demonstrated significantly higher rates of aseptic loosening/mechanical failure within 2 years, longer lengths of stay, and higher rates of urinary tract infection, pneumonia, deep vein thrombosis, and acute kidney injury within 90 days. Compared to smokers, smokeless tobacco users demonstrated significantly lower rates of aseptic revision and lower rates of wound disruption. CONCLUSION Smokeless tobacco use is associated with higher rates of both medical and joint complications following primary TKA. However, smoking is associated with higher risk for complications than smokeless tobacco use. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND Prior studies have shown disparities in utilization of primary and revision total hip arthroplasty (THA). However, little is known about patient population differences associated with elective and nonelective surgery. Therefore, the aim of this study was to explore factors that influence primary utilization and revision risk of THA based on surgery indication. METHODS Data were obtained from 7,543 patients who had a primary THA from 2014 to 2020 in a database, which consists of multiple health partner systems in Louisiana and Texas. Of these patients, 602 patients (8%) underwent nonelective THA. THA was classified as "elective" or "nonelective" if the patient had a diagnosis of hip osteoarthritis or femoral neck fracture, respectively. RESULTS After multivariable logistic regression, nonelective THA was associated with alcohol dependence, lower body mass index (BMI), women, and increased age and number of comorbid conditions. No racial or ethnic differences were observed for the utilization of primary THA. Of the 262 patients who underwent revision surgery, patients who underwent THA for nonelective etiologies had an increased odds of revision within 3 years of primary THA (odds ratio (OR) = 1.66, 95% Confidence Interval (CI) = 1.06-2.58, P-value = .025). After multivariable logistic regression, patients who had tobacco usage (adjusted odds ratio (aOR) = 1.36, 95% CI = 1.04-1.78, P-value = .024), alcohol dependence (aOR = 2.46, 95% CI = 1.45-4.15, P-value = .001), and public insurance (OR = 2.08, 95% CI = 1.18-3.70, P-value = .026) had an increased risk of reoperation. CONCLUSION Demographic and social factors impact the utilization of elective and nonelective primary THA and subsequent revision surgery. Orthopaedic surgeons should focus on preoperative counseling for tobacco and alcohol cessation as these are modifiable risk factors to directly decrease reoperation risk.

Abstract
Background The link between tobacco consumption and wound complications following total knee arthroplasty (TKA) is well established. However, the effect of tobacco use on biologic fixation in cementless TKA remains unknown. This study evaluated the influence of tobacco use on the presence of radiolucent lines of tibial components in cementless TKA. Methods A total of 293 consecutive cementless TKAs of 2 contemporary designs were retrospectively reviewed. Tibial radiolucent lines and component alignment were measured using an established measurement protocol. Patients with any history of tobacco use or active tobacco use (tobacco users) were compared to those with no history of tobacco use (tobacco nonusers). No significant differences which influenced outcomes were detected between the tobacco user and tobacco nonuser groups (P ≥ .071). Results Radiolucent lines decreased from 1-month to latest follow-up (mean 2.5 years) in all 10 radiographic zones regardless of tobacco use (P ≤ .084). However, evaluating intrapatient change in radiolucent line width, the tobacco nonuser group had more radiolucent lines resolve by the latest follow-up in nearly all radiographic zones, although most differences did not reach statistical significance, except for anteroposterior zone 1 (-31% vs -19%, P = .022). No tibial components were revised for aseptic loosening. Conclusions Results from this study suggest that any tobacco use prior to cementless TKA has the potential to hinder biologic fixation of tibial components. While no tibial components were revised for aseptic loosening, follow-up was relatively short at 2.5 years and therefore warrants further study to discern the effect of persistent radiolucent lines on long-term fixation.

Abstract
INTRODUCTION Smoking has been associated with numerous adverse outcomes following surgical procedures. The purpose of this study was to investigate, whether smoking status at time of surgery influences the outcome of primary TKA. MATERIALS AND METHODS Six hundred and eighty-one patients who underwent primary TKA between 2003 and 2006 were included in the study. Smoking status was defined as current, former, and never smoker. Complications leading to revisions were assessed until 17 years of follow-up. Functional outcome was evaluated using clinical scores: Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Visual Analogue Scale (VAS) for pain, Short Form-12 Physical and Mental Component Summaries (SF-12PCS/MCS), and Knee Society Function and Knee Score (KSFS and KSKS). RESULTS At a mean follow-up of 95 months (± 47 months), 124 complications led to revision surgery. Soft-tissue complications (OR, 2.35 [95% CI 1.08-5.11]; p = 0.032), hematoma formation (OR, 5.37 [95% CI 1.01-28.49]; p = 0.048), and restricted movement (OR, 3.51 [95% CI 1.25-9.84]; p = 0.017) were more likely to occur in current smokers than never smokers. Current smokers were more likely to score higher at KSFS (p < 0.001) and SF-12PCS (p = 0.0197) compared to never smokers. For overall revision, differences were noted. CONCLUSION Current smoking increases risk of soft-tissue complications and revision after primary TKA, especially due to hematoma and restricted movement. Smoking cessation programs could reduce the risk of revision surgery.

Abstract
The association of morbid obesity with increased revision total knee arthroplasty (rTKA) complications is potentially confounded by concurrent risk factors. This study was performed to evaluate whether morbid obesity was more strongly associated with adverse aseptic rTKA outcomes than diabetes or tobacco use history-when present as a solitary major risk factor. Demographic characteristics, surgical indications, and adverse outcomes (reoperation, revision, infection, and amputation) were compared between 270 index aseptic rTKA performed for patients with morbid obesity (n = 73), diabetes (n = 72), or tobacco use (n = 125) and 239 "healthy" controls without these risk factors at a mean 75.7 (range: 24-111) months. There was no difference in 2-year reoperation rate (17.8 vs. 17.6%, p = 1.0) or component revision rate (8.2 vs. 8.4%) between morbidly obese and healthy patients. However, higher reoperation rates were noted in patients with diabetes (p = 0.02) and tobacco use history (p < 0.01), including higher infection (p < 0.05) and above knee amputation (p < 0.01) rates in patients with tobacco use history. Multivariate analysis retained an independent association between smoking history and amputation risk (odds ratio: 7.4, 95% confidence interval: 1.7-55.2, p < 0.01). Morbid obesity was not associated with an increased risk of reoperation or component revision compared with healthy patients undergoing aseptic revision. Tobacco use was associated with increased reoperation and above knee amputation. Additional study will be beneficial to determine whether risk reduction efforts are effective in mitigating postoperative complication risks.

Abstract
BACKGROUND Smoking increases risk of several complications after total hip or knee arthroplasty (THA/TKA), so we systematically reviewed and meta-analyzed the literature to take into account all relevant evidence, particularly studies published since 2010. METHODS The PubMed, Ovid Embase, Web of Science, and EBSCOHost databases were searched and studies were selected and analyzed according to MOOSE recommendations. Methodological quality of included studies was assessed using the Newcastle-Ottawa Scale. Data were qualitatively synthesized or meta-analyzed using a random-effects model. RESULTS A total of 40 studies involving 3,037,683 cases were included. Qualitative analysis suggested that smoking is associated with worse patient-reported outcomes within one year after surgery, and meta-analysis showed that smoking significantly increased risk of the following outcomes: total complications (OR 1.41, 95% CI 1.01-1.98), wound complications (OR 1.77, 95% CI 1.50-2.10), prosthetic joint infection (OR 1.84, 95% CI 1.52-2.24), aseptic loosening (OR 1.62, 95% CI 1.12-2.34), revision (OR 2.12, 95% CI 1.46-3.08), cardiac arrest (OR 4.90, 95% CI 2.26-10.60), cerebrovascular accident (OR 2.22, 95% CI 1.01-4.85), pneumonia (OR 2.35, 95% CI 1.17-4.74), acute renal insufficiency (OR 2.01, 95% CI 1.48-2.73), sepsis (OR 4.35, 95% CI 1.35-14.00), inpatient mortality (OR 12.37, 95% CI 4.46-34.28), and persistent opioid consumption (OR 1.64, 95% CI 1.39-1.92). CONCLUSION Smoking patients undergoing THA and TKA are at increased risk of numerous complications, inpatient mortality, persistent opioid consumption, and worse 1-year patient-reported outcomes. Pre-surgical protocols for these outcomes should give special consideration to smoking patients.

Abstract
Periprosthetic joint infection (PJI) is a major adverse event of primary total knee arthroplasty (TKA) from the patient's perspective, and it is also costly for health care systems. In 2010, the reported incidence of PJI in the first 2 years after TKA was 1.55%, with an incidence of 0.46% between the second and tenth year. In 2022, it has been published that 1.41% of individuals require revision TKA for PJI. The following risk factors have been related to an increased risk of PJI: male sex, younger age, type II diabetes, obesity class II, hypertension, hypoalbuminemia, preoperative nutritional status as indicated by prognostic nutritional index (PNI) and body mass index, rheumatoid arthritis, post-traumatic osteoarthritis, intra-articular injections prior to TKA, previous multi-ligament knee surgery, previous steroid therapy, current tobacco use, procedure type (bilateral), length of stay over 35 days, patellar resurfacing, prolonged operative time, use of blood transfusions, higher glucose variability in the postoperative phase, and discharge to convalescent care. Other reported independent risk factors for PJI (in diminishing order of importance) are congestive heart failure, chronic pulmonary illness, preoperative anemia, depression, renal illness, pulmonary circulation disorders, psychoses, metastatic tumor, peripheral vascular illness, and valvular illness. Preoperative intravenous tranexamic acid has been reported to diminish the risk of delayed PJI. Knowing the risk factors for PJI after TKA, especially those that are avoidable or controllable, is critical to minimizing (ideally preventing) this complication. These risk factors are outlined in this article.

A Matched Cohort Study. Orthop J Sports Med 2022; 10:23259671221126508. [PMID: 36199826 PMCID: PMC9528006 DOI: 10.1177/23259671221126508] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Accepted: 07/27/2022] [Indexed: 12/03/2022] Open
Abstract
Background: Hip arthroscopy (HA) procedures have increased exponentially in recent years. Their effect on outcomes after subsequent total hip arthroplasty (THA) remains unclear. Purpose: To compare rates of complications and opioid claims after elective THA among patients with prior HA versus controls. Study Design: Cohort study; Level of evidence, 3. Methods: Patients who underwent THA were identified in the PearlDiver database. Arthroplasty performed for hip fractures and hip avascular necrosis were excluded. Within this population, patients with HA before arthroplasty (n = 3156) were propensity score matched 1:1 with controls on age, sex, US region, and several comorbidities. Rates of medical complications within 90 days and prosthesis-related complications within 2 years were queried. The number of patients with an opioid claim within 0 to 30 days and subsequent opioid claim(s) during the 90-day global period were obtained to assess rates of prolonged opioid use after arthroplasty. Rates of postoperative complications and opioid claims were compared using logistic regression. Results: Patients with prior HA exhibited significantly lower rates of readmission (5.6% vs 7.3%; odds ratio [OR], 0.72), pulmonary embolism (0.2% vs 0.6%; OR, 0.45), urinary tract infection (3.1% vs 4.0%; OR, 0.75), and blood transfusion (3.6% vs 6.1%; OR, 0.55). The prior HA cohort also exhibited a significantly lower rate of prosthetic joint infection at 1 year postoperatively (0.6% vs 1.3%; OR, 0.50). Rates of dislocation, periprosthetic fracture, mechanical complications, and aseptic revision arthroplasty were statistically comparable between the cohorts within 2 years. The prior HA cohort was significantly less likely to file persistent opioid claims after 30 days postoperatively, including between 31 and 60 days (27.2% vs 33.1%; OR, 0.74) and 61 to 90 days (16.2% vs 20.9%; OR, 0.71). Conclusion: After elective THA, patients with prior HA exhibited significantly lower rates of medical complications and prolonged opioid claims within 90 days and prosthetic joint infection at 1 year. Rates of all other prosthesis-related complications within 2 years were statistically comparable.

Abstract
Cigarette consumption negatively impacts bone quality and is a risk-factor for the development of multiple bone associated disorders, due to the highly vascularised structure of bone being exposed to systemic factors. However, the impact on bone to electronic cigarette (e-cigarette) use, which contains high doses of nicotine and other compounds including flavouring chemicals, metal particulates and carbonyls, is poorly understood. Here, we present the first evidence demonstrating the impact of e-cigarette vapour condensate (replicating changes in e-cigarette liquid chemical structure that occur upon device usage), on human primary osteoblast viability and function. 24 h exposure of osteoblasts to e-cigarette vapour condensate, generated from either second or third generation devices, significantly reduced osteoblast viability in a dose dependent manner, with condensate generated from the more powerful third generation device having greater toxicity. This effect was mediated in-part by nicotine, since exposure to nicotine-free condensate of an equal concentration had a less toxic effect. The detrimental effect of e-cigarette vapour condensate on osteoblast viability was rescued by co-treatment with the antioxidant N-Acetyl-L-cysteine (NAC), indicating toxicity may also be driven by reactive species generated upon device usage. Finally, non-toxic doses of either second or third generation condensate significantly blunted osteoblast osteoprotegerin secretion after 24 h, which was sustained for up to 7 days. In summary we demonstrate that e-cigarette vapour condensate, generated from commonly used second and third generation devices, can significantly reduce osteoblast viability and impair osteoblast function, at physiologically relevant doses. These data highlight the need for further investigation to inform users of the potential risks of e-cigarette use on bone health, including, accelerating bone associated disease progression, impacting skeletal development in younger users and to advise patients following orthopaedic surgery, dental surgery, or injury to maximise bone healing.

Abstract
Background: Total joint arthroplasty (TJA) is one of the most common procedures performed in the United States. Outcomes of this elective procedure may be improved via preoperative optimization of modifiable risk factors. Purposes: We sought to summarize the literature on the clinical implications of preoperative risk factors in TJA and to develop recommendations regarding preoperative optimization of these risk factors. Methods: We searched PubMed in August 2019 with an update in September 2020 for English-language, peer-reviewed publications assessing the influence on outcomes in total hip and knee replacement of 7 preoperative risk factors-obesity, malnutrition, hypoalbuminemia, diabetes, anemia, smoking, and opioid use-and recommendations to mitigate them. Results: Sixty-nine studies were identified, including 3 randomized controlled trials, 8 prospective cohort studies, 42 retrospective studies, 6 systematic reviews, 3 narrative reviews, and 7 consensus guidelines. These studies described worse outcomes associated with these 7 risk factors, including increased rates of in-hospital complications, transfusions, periprosthetic joint infections, revisions, and deaths. Recommendations for strategies to screen and address these risk factors are provided. Conclusions: Risk factors can be optimized, with evidence suggesting the following thresholds prior to surgery: a body mass index <40 kg/m2, serum albumin ≥3.5 g/dL, hemoglobin A1C ≤7.5%, hemoglobin >12.0 g/dL in women and >13.0 g/dL in men, and smoking cessation and ≥50% decrease in opioid use by 4 weeks prior to surgery. Surgery should be delayed until these risk factors are adequately optimized.

Abstract
The perioperative management of patients who are smokers presents anesthesiologists with various challenges related to respiratory, circulatory, and other clinical problems. Regarding 30-day postoperative outcomes, smokers have higher risks of mortality and complications than non-smokers, including death, pneumonia, unplanned tracheal intubation, mechanical ventilation, cardiac arrest, myocardial infarction, and stroke. Given the benefits of smoking cessation and the adverse effects of smoking on perioperative patient management, patients should quit smoking long before surgery. However, anesthesiologists cannot address these issues alone. The Japanese Society of Anesthesiologists established guidelines in 2015 (published in a medical journal in 2017) to enlighten surgical staff members and patients regarding perioperative tobacco cessation. The primary objective of perioperative smoking cessation is to reduce the risks of adverse cardiovascular and respiratory events, wound infection, and other perioperative complications. Perioperative preparations constitute a powerful teachable moment, a "golden opportunity" for smoking cessation to achieve improved primary disease outcomes and prevent the occurrence of tobacco-related conditions. This review updates the aforementioned guidelines as a practical guide to cover the nuts and bolts of perioperative smoking cessation. Its goal is to assist surgeons, anesthesiologists, and other medical professionals and to increase patients' awareness of smoking risks before elective surgery.

Abstract
Spinal cord stimulation (SCS) for intractable pain syndromes has become a pillar of modern pain management. Common complications include lead migration, implant infection, cerebral spinal fluid leak, and lead fracture. Spinal epidural abscess due to spinal cord stimulator implantation is a very rare occurrence with only two cases reported in the literature so far. We present an illustrative case and discuss the pathophysiology and best clinical management for this very rate entity.

Abstract
AIMS Thresholds of acceptable early migration of the components in total knee arthroplasty (TKA) have traditionally ignored the effects of patient and implant factors that may influence migration. The aim of this study was to determine which of these factors are associated with overall longitudinal migration of well-fixed tibial components following TKA. METHODS Radiostereometric analysis (RSA) data over a two-year period were available for 419 successful primary TKAs (267 cemented and 152 uncemented in 257 female and 162 male patients). Longitudinal analysis of data using marginal models was performed to examine the associations of patient factors (age, sex, BMI, smoking status) and implant factors (cemented or uncemented, the size of the implant) with maximum total point motion (MTPM) migration. Analyses were also performed on subgroups based on sex and fixation. RESULTS In the overall group, only fixation was significantly associated with migration (p < 0.001). For uncemented tibial components in males, smoking was significantly associated with lower migration (p = 0.030) and BMI approached significance (p = 0.061). For females with uncemented components, smoking (p = 0.081) and age (p = 0.063) approached significance and were both associated with increased migration. The small number of self-reported smokers in this study warrants cautious interpretation and further investigation. For cemented components in females, larger sizes of tibial component were significantly associated with increased migration (p = 0.004). No factors were significant for cemented components in males. CONCLUSION The migration of uncemented tibial components was more sensitive to patient factors than cemented implants. These differences were not consistent by sex, suggesting that it may be of value to evaluate female and male patients separately following TKA. Cite this article: Bone Joint J 2022;104-B(4):444-451.

Cannabis Use Disorder in the Setting of Primary Total Hip Arthroplasty: Understanding the Epidemiology, Demographic Characteristics, and Inpatient Postoperative Outcomes. J Am Acad Orthop Surg 2022; 30:321-328.

Abstract
INTRODUCTION Cannabis use is expected to increase in the context of its decriminalization and legalization in several states. The purpose of this study was to report on the epidemiologic and demographic characteristics and inpatient postoperative outcomes of patients with cannabis use disorder (CUD) undergoing primary total hip arthroplasty (THA). METHODS The National Inpatient Sample registry was used to identify patients undergoing THA between 2006 and 2015. Patients were stratified into groups with and without CUD. Epidemiology, comorbidity, and outcomes data were comparatively analyzed between these two groups. RESULTS A total of 2,838,742 THAs were performed during the study period. The prevalence of CUD significantly increased from 0.10% in 2006 to 0.39% in 2015 (P < 0.0001). Patients with CUD were significantly younger, more likely to be male, had higher rates of Medicaid insurance and were more likely to be non-Hispanic Black and less likely to be non-Hispanic White when compared with the control group. When comparing patients with and without CUD, there was no significant difference in the composite any complication variable and no significant difference in seven of eight individual in-hospital complications assessed, with the exception being higher genitourinary complications in the CUD group. There were no significant differences in discharge disposition or length of stay. DISCUSSION Although CUD is significantly associated with various demographic, comorbidity, and hospital characteristics, it is not significantly associated with in-hospital complications, discharge disposition, and length of stay outcomes in the immediate in-hospital, postoperative period. It is critical for clinicians and public health professionals to understand the characteristics and expected inpatient outcomes of this evolving population of patients with CUD undergoing THA, particularly in the context of widespread legalization.

Abstract
Background: Surgical site infections (SSIs) significantly influence outcomes and health care costs after orthopaedic surgery, but they have not been well characterized for osteochondral allograft (OCA) transplantation with or without meniscal allograft transplantation (MAT). Purpose: To characterize the incidence, cost, and risk factors associated with potential or confirmed SSIs after large single-surface, multisurface, or bipolar allograft transplantation in the knee. Study Design: Case-control study; Level of evidence, 3. Methods: Prospectively collected registry data were analyzed for patients who underwent primary or revision OCA transplantation with or without MAT in the knee. The Centers for Disease Control and Prevention (CDC) guidelines were used to define SSIs and calculate the SSI incidence. Both potential and confirmed SSIs were analyzed to determine related treatment methods, calculate associated health care costs, and characterize risk factors based on the OCA surgery type (single-surface, multisurface, bipolar, ±MAT), American Society of Anesthesiologists physical status classification system, surgery duration, length of stay, age, sex, body mass index (BMI), and current tobacco use. Results: A total of 224 patients were included in the analysis. There were 2 SSIs in 1 patient that met CDC criteria, such that the incidence for this patient population was 0.9%. An additional 7 patients (3.1%) were examined for potential infections not classified as SSIs. Patients with potential or confirmed SSIs had a significantly higher mean BMI compared to patients with no evidence of an SSI ( P <.001). BMI >35 (odds ratio, 9.1) and tobacco use (odds ratio, 6.6) were associated with greater odds for a potential or confirmed SSI. The mean health care costs were $6101 for patients who required additional emergency room visits and/or irrigation and debridement within 90 days postoperatively for potential or confirmed SSIs, $19 for patients with potential superficial incisional SSIs, and $12,100 for patients who experienced a potential or confirmed deep incisional or organ/space SSI >90 days from surgery. Conclusion: Large OCA transplantation with and without MAT were associated with a low incidence of confirmed SSIs (0.9%), and patients with BMI >35 and current tobacco use had greater odds of an SSI. Potential and confirmed SSIs were associated with unscheduled appointments, additional surgical procedures, and higher costs.

Abstract
The systematic integration of evidence-based tobacco treatment has yet to be broadly viewed as a standard-of-care. The Framework Convention on Tobacco Control recommends the provision of support for tobacco cessation. We argue that the provision of smoking cessation services in clinical settings is a fundamental clinical responsibility and permits the opportunity to more effectively assist with cessation. The role of clinicians in prioritising smoking cessation is essential in all settings. Clinical benefits of implementing cessation services in hospital settings have been recognised for three decades-but have not been consistently provided. The Ottawa Model for Smoking Cessation has used an 'organisational change' approach to its introduction and has served as the basis for the introduction of cessation programmes in hospital and primary care settings in Canada and elsewhere. The significance of smoking cessation dwarfs that of many preventive interventions in primary care. Compelling evidence attests to the importance of providing cessation services as part of cancer treatment, but implementation of such programmes has been slow. We recognise that the provision of such services must reflect the realities and resources of a particular health system. In low-income and middle-income countries, access to treatment facilities pose unique challenges. The integration of cessation programmes with tuberculosis control services may offer opportunities; and standardisation of peri-operative care to include smoking cessation may not require additional resources. Mobile phones afford unique opportunities for interactive cessation programming. Health system change is fundamental to improving the provision of cessation services; clinicians can be powerful advocates for such change.

Abstract
BACKGROUND As indications for elective total hip arthroplasty (THA) expand to younger patients, we sought to (1) compare revision risk following primary elective THA in patients <55 years at the time of their THA to patients aged ≥65 years and (2) identify specific risk factors for revision in patients <55 years. METHODS A Kaiser Permanente's total joint replacement registry was used to conduct a cohort study including primary elective THA patients aged ≥18 (2001-2018). In total, 11,671 patients <55 years and 53,106 patients ≥65 years were included. Multiple Cox regression was used to evaluate cause-specific revision risk, including septic revision, aseptic loosening, instability, and periprosthetic fracture. Stepwise Cox regression was used to identify patient and surgical factors associated with cause-specific revision in patients <55 years. RESULTS Patients <55 years had a higher risk of septic revision (hazard ratio [HR] = 1.30, 95% confidence interval [CI] = 1.02-1.66), aseptic loosening (HR = 2.60, 95% CI = 1.99-3.40), and instability (HR = 1.35, 95% CI = 1.09-1.68), but a lower risk of revision for periprosthetic fracture (HR = 0.36, 95% CI = 0.22-0.59) compared to patients aged ≥65 years. In the <55 age group, risk factors for septic revision included higher body mass index, drug abuse, and liver disease. Hypertension, anterior approach, and ceramic-on-ceramic were associated with aseptic loosening. White race, American Society of Anesthesiologists classification ≥3, smoker, paralysis, posterior approach, ceramic-on-ceramic, and smaller head diameter were associated with instability. CONCLUSION Identified risk factors varied depending on the cause for revision. Although septic revisions were related to patient characteristics, more modifiable factors, such as implant or surgical approach, were associated with revision due to aseptic loosening and instability.

Abstract
Background Surgical repair for shoulder instability includes arthroscopic Bankart, open Bankart, and Latarjet-Bristow. Methods This is a cohort study of patients who underwent arthroscopic Bankart, open Bankart, or Latarjet-Bristow procedures that were identified within the National Surgical Quality Improvement Program database (2007-2019). Unadjusted and adjusted analyses were performed (α = 0.05). Outcomes included 30-day adverse events, readmission, and operative time. Results This study included 10,955 patients (9128 arthroscopic Bankart, 1148 open Bankart, and 679 Latarjet-Bristow). Compared with arthroscopic Bankart, Latarjet-Bristow had longer operative times (129.96 [95% CI: 126.49-133.43] vs. 86.35 [85.51-87.19] minutes), along with a higher percentage of serious adverse events (2.5% vs. 0.4%), reoperation (1.9% vs. 0.1%), readmission (1.8% vs. 0.3%), thromboembolic complications (0.4% vs. 0.1%), and sepsis (0.4% vs. 0.0%) (P < .05 for all). Open Bankart had longer operative times (98.17 [95.52-100.82] vs. 86.35 [85.51-87.19] minutes) and a higher percentage of sepsis (0.2% vs. 0.0%) (P < .05 both). Latarjet-Bristow had increased odds of a serious adverse event (odds ratio [OR]: 7.68 [4.19-14.07]), reoperation (OR: 17.32 [7.58-39.56]), readmission (OR: 5.73 [2.84-11.54]), and deep wound complications (OR: 14.98 [3.92-57.23]) (P < .05 for all). In comparing the relative utilization of arthroscopic versus open Bankart, arthroscopic Bankart increased (83.4% to 91.2%) while open Bankart decreased (16.6% to 8.8%) from the 2011-2013 time period to 2017-2019 (Ptrend < .001). Conclusion In addition to a low complication rate, the relative utilization of arthroscopic Bankart increased compared with open Bankart over the past decade. Furthermore, Latarjet-Bristow was associated with a higher incidence of serious adverse events than arthroscopic Bankart.

Abstract
This is a retrospective study. Surgical site infection (SSI) is associated with adverse postoperative outcomes following total knee arthroplasty (TKA). However, accurately predicting SSI remains a clinical challenge due to the multitude of patient and surgical factors associated with SSI. This study aimed to develop and validate machine learning models for the prediction of SSI following primary TKA. This is a retrospective study for patients who underwent primary TKA. Chart review was performed to identify patients with superficial or deep SSIs, defined in concordance with the criteria of the Musculoskeletal Infection Society. All patients had a minimum follow-up of 2 years (range: 2.1-4.7 years). Five machine learning algorithms were developed to predict this outcome, and model assessment was performed by discrimination, calibration, and decision curve analysis. A total of 10,021 consecutive primary TKA patients was included in this study. At an average follow-up of 2.8 ± 1.1 years, SSIs were reported in 404 (4.0%) TKA patients, including 223 superficial SSIs and 181 deep SSIs. The neural network model achieved the best performance across discrimination (area under the receiver operating characteristic curve = 0.84), calibration, and decision curve analysis. The strongest predictors of the occurrence of SSI following primary TKA, in order, were Charlson comorbidity index, obesity (BMI >30 kg/m2), and smoking. The neural network model presented in this study represents an accurate method to predict patient-specific superficial and deep SSIs following primary TKA, which may be employed to assist in clinical decision-making to optimize outcomes in at-risk patients.

Abstract
Given a national push toward bundled payment models, the purpose of this study was to examine the prevalence as well as the effect of smoking on early inpatient complications and cost following elective total knee arthroplasty (TKA) in the United States across multiple years. Using the nationwide inpatient sample, all primary elective TKA admissions were identified from 2012 to 2014. Patients were stratified by smoking status through a secondary diagnosis of "tobacco use disorder." Patient characteristics as well as prevalence, costs, and incidence of complications were compared. There was a significant increase in the rate of smoking in TKA from 17.9% in 2012 to 19.2% in 2014 (p < 0.0001). The highest rate was seen in patients < 45 years of age (27.3%). Hospital resource usage was significantly higher for smokers, with a length of stay of 3.3 versus 2.9 days (p < 0.0001), and hospital costs of $16,752 versus $15,653 (p < 0.0001). A multivariable logistic model adjusting for age, gender, and comorbidities showed that smokers had an increased odds ratio for myocardial infarction (5.72), cardiac arrest (4.59), stroke (4.42), inpatient mortality (4.21), pneumonia (4.01), acute renal failure (2.95), deep vein thrombosis (2.74), urinary tract infection (2.43), transfusion (1.38) and sepsis (0.65) (all p < 0.0001). Smoking is common among patients undergoing elective TKA, and its prevalence continues to rise. Smoking is associated with higher hospital costs as well as higher rates of immediate inpatient complications. These findings are critical for risk stratification, improving of bundled payment models as well as patient education, and optimization prior to surgery to reduce costs and complications.

Abstract
AIMS To describe the risk of periprosthetic joint infection (PJI) and reoperation in patients who have an acute, traumatic wound dehiscence following total knee arthroplasty (TKA). METHODS From January 2002 to December 2018, 16,134 primary TKAs were performed at a single institution. A total of 26 patients (0.1%) had a traumatic wound dehiscence within the first 30 days. Mean age was 68 years (44 to 87), 38% (n = 10) were female, and mean BMI was 34 kg/m2 (23 to 48). Median time to dehiscence was 13 days (interquartile range (IQR) 4 to 15). The dehiscence resulted from a fall in 22 patients and sudden flexion after staple removal in four. The arthrotomy was also disrupted in 58% (n = 15), including a complete extensor mechanism disruption in four knees. An irrigation and debridement with component retention (IDCR) was performed within 48 hours in 19 of 26 knees and two-thirds were discharged on antibiotic therapy. The mean follow-up was six years (2 to 15). The association of wound dehiscence and the risk of developing a PJI was analyzed. RESULTS Patients who sustained a traumatic wound dehiscence had a 6.5-fold increase in the risk of PJI (95% confidence interval (CI) 1.6 to 26.2; p = 0.008). With the small number of PJIs, no variables were found to be significant risk factors. However, there were no PJIs in any of the patients who were treated with IDCR and a course of antibiotics. Three knees required reoperation including one two-stage exchange for PJI, one repeat IDCR for PJI, and one revision for aseptic loosening of the tibial component. CONCLUSION Despite having a traumatic wound dehiscence, the risk of PJI was low, but much higher than experienced in all other TKAs during the same period. We recommend urgent IDCR and a course of postoperative antibiotics to decrease the risk of PJI. A traumatic wound dehiscence increases risk of PJI by 6.5-fold.

Abstract
BACKGROUND In contrast to cigarettes, electronic cigarette use (E-cigarettes) has grown substantially over the last decade. This is due to their promotion as both a safer alternative to cigarettes and as an aide to stop smoking. Critically, upon E-cigarette use, the user may be exposed to high doses of nicotine in addition to other compounds including flavouring chemicals, metal particulates and carbonyl compounds, particularly in highly vascularised tissues such as bone. However, there has been limited investigation into the impact of E-cigarette usage on bone physiology, particularly over extended time periods and there are no clinical recommendations regarding E-cigarette usage in relation to orthopaedic surgery. This literature review draws together data from studies that have investigated the impact of E-cigarette vapour and its major constituents on bone, detailing the models utilised and the relevant mechanistic and functional results. MAIN BODY Currently there is a lack of studies both in vivo and in vitro that have utilised E-cigarette vapour, necessary to account for changes in chemical composition of E-cigarette liquids upon vaping. There is however evidence that human bone and bone cells express nicotine receptors and exposure of both osteoblasts and osteoclasts to nicotine, in high concentrations may reduce their viability and impair function. Similarly, it appears that aldehydes and flavouring chemicals may also negatively impact osteoblast viability and their ability to form bone. However, such functional findings are predominantly the result of studies utilising bone cell lines such as MG-63 or Saos-2 cells, with limited use of human osteoblasts or osteoclasts. Additionally, there is limited consideration for a possible impact on mesenchymal stem cells, which can also play an import role in bone repair. CONCLUSION Understanding the function and mechanism of action of the various components of E-cigarette vapour in mediating human bone cell function, in addition to long term studies to determine the potential harm of chronic E-cigarette use on human bone will be important to inform users of potential risks, particularly regarding bone healing following orthopaedic surgery and injury.

Abstract
BACKGROUND Forty percent of long bone fractures involve the tibia. These fractures are associated with prolonged recovery and may adversely affect patients' long-term physical functioning; however, there is limited evidence to inform what factors influence functional recovery in this patient population. QUESTION/PURPOSE In a secondary analysis of a previous randomized trial, we asked: What fracture-related, demographic, social, or rehabilitative factors were associated with physical function 1 year after reamed intramedullary nailing of open or closed tibial shaft fractures? METHODS This is a secondary (retrospective) analysis of a prior randomized trial (Trial to Re-evaluate Ultrasound in the Treatment of Tibial Fractures; TRUST trial). In the TRUST trial, 501 patients with unilateral open or closed tibial shaft fractures were randomized to self-administer daily low-intensity pulsed ultrasound or use a sham device, of which 15% (73 of 501) were not followed for 1 year due to early study termination as a result of futility (no difference between active and sham interventions). Of the remaining patients, 70% (299 of 428) provided full data. All fractures were fixed using reamed (298 of 299) or unreamed (1 of 299) intramedullary nailing. Thus, we excluded the sole fracture fixed using unreamed intramedullary nailing. The co-primary study outcomes of the TRUST trial were time to radiographic healing and SF-36 physical component summary (SF-36 PCS) scores at 1-year. SF-36 PCS scores range from 0 to 100, with higher scores being better, and the minimum clinically important difference (MCID) is 5 points. In this secondary analysis, based on clinical and biological rationale, we selected factors that may be associated with physical functioning as measured by SF-36 PCS scores. All selected factors were inserted simultaneously into a multivariate linear regression analysis. RESULTS After adjusting for potentially confounding factors, such as age, gender, and injury severity, we found that no factor showed an association that exceeded the MCID for physical functioning 1 year after intramedullary nailing for tibial shaft fractures. The independent variables associated with lower physical functioning were current smoking status (mean difference -3.0 [95% confidence interval -5 to -0.5]; p = 0.02), BMI > 30 kg/m2 (mean difference -3.0 [95% CI -5.0 to -0.3]; p = 0.03), and receipt of disability benefits or involvement in litigation, or plans to be (mean difference -3.0 [95% CI -5.0 to -1]; p = 0.007). Patients who were employed (mean difference 4.6 [95% CI 2.0 to 7]; p < 0.001) and those who were advised by their surgeon to partially or fully bear weight postoperatively (mean difference 2.0 [95% CI 0.1 to 4.0]; p = 0.04) were associated with higher physical functioning. Age, gender, fracture severity, and receipt of early physical therapy were not associated with physical functioning at 1-year following surgical fixation. CONCLUSION Among patients with tibial fractures, none of the factors we analyzed, including smoking status, receipt of disability benefits or involvement in litigation, or BMI, showed an association with physical functioning that exceeded the MCID. LEVEL OF EVIDENCE Level III, therapeutic study.

Abstract
Smoking is known to increase the risk of peri-operative complications in Orthoplastic surgery by impairing bone and wound healing. The effects of nicotine replacement therapies (NRTs) and electronic cigarettes (e-cigarettes) has been less well established. Previous reviews have examined the relationship between smoking and bone and wound healing separately. This review provides surgeons with a comprehensive and contemporaneous account of how smoking in all forms interacts with all aspects of complex lower limb trauma. We provide a guide for surgeons to refer to during the consent process to enable them to tailor information towards smokers in such a way that the patient may understand the risks involved with their surgical treatment. We update the literature with recently discovered methods of monitoring and treating the troublesome complications that occur more commonly in smokers effected by trauma.

Abstract
INTRODUCTION Zolpidem has gained popularity as a pharmaceutical therapy for insomnia, being the most prescribed hypnotic in the United States today. However, it is associated with increased mortality and morbidity. Literature regarding zolpidem use in the total knee arthroplasty (TKA) population is limited. The aim of the study was to analyze postoperative zolpidem use in the TKA population regarding medical and implant complications, falls, and readmission. METHODS The study group was queried according to zolpidem use. Controls consisted of patients who underwent primary TKA without a history of hypnotic drug use. Study group patients were matched to controls in a 1:5 ratio by demographics and comorbidities. Results yielded 99,178 study participants and 495,795 controls. Primary endpoints included 90-day medical and implant complications, fall risk, and readmission. Chi-squared test was used to compare categorical variables. Multivariate logistic regression was used to calculate odds (OR) for complications, fall risk, and readmission. A P value less than 0.05 was considered statistically significant. RESULTS Study group patients had increased odds of medical complications (OR: 1.76, 95% CI: 1.71-1.82, P < .0001) and implant complications (OR: 1.35, 95% CI: 1.23-1.47, P < .0001) compared to controls. Furthermore, patients in the study group were found to have an increased risk of 90- day falls (OR: 1.16, 95% CI: 1.11-1.21, P < .0001). Readmission was similar to controls (5.10% vs 4.84%, P = .12). CONCLUSION Zolpidem use following primary TKA is associated with the risk of morbidity and falls. The findings are consistent with the literature regarding zolpidem. These findings may affect discussion between orthopedic surgeons and patients in the decision-making process prior to undergoing TKA.

Abstract
BACKGROUND Pigmented villonodular synovitis (PVNS) is a condition affecting larger joints such as the hip and knee. Little is known regarding the impact of PVNS on total hip arthroplasty (THA). Therefore, the aim of this study is to determine if patients with PVNS of the hip undergoing primary THA experience greater (1) in-hospital lengths of stay (LOS); (2) complications; (3) readmission rates; and (4) costs. METHODS Patients undergoing primary THA for PVNS of the hip from the years 2005 to 2014 were identified using a nationwide claims registry. PVNS patients were matched to a control cohort in a 1:5 ratio by age, gender, and various comorbidities. The query yielded 7440 patients with (n = 1240) and without (n = 6200) PVNS of the hip undergoing primary THA. Endpoints analyzed included LOS, complications, readmission rates, and costs. Multivariate logistic regression was used to determine odds ratios (OR) of developing complications. Welch's t-tests were used to test for significance in LOS and cost between the cohorts. A P-value less than .001 was considered statistically significant. RESULTS PVNS patients had approximately 8% longer in-hospital LOS (3.8 vs 3.5 days, P = .0006). PVNS patients had greater odds of (OR 1.60, P < .0001) medical and (OR 1.81, P < .0001) implant-related complications. Furthermore, PVNS patients were found to have higher odds (OR 1.84, P < .0001) of 90-day readmissions. PVNS patients also incurred higher day of surgery ($13,119 vs $11,983, P < .0001) and 90-day costs ($17,169 vs $15,097, P < .0001). CONCLUSION Without controlling for global trends in LOS, complications, readmissions, or costs between 2005 and 2014, the findings of the study suggest that PVNS of the hip is associated with worse outcomes and higher costs following primary THA. The study is useful as orthopedic surgeons can use the study to educate patients of the complications which may occur following their hip surgery.

Abstract
The effect of tobacco smoking on foot and ankle procedures is likely to be more pronounced when compared to other orthopaedic surgery. This is due to the peripheral nature of the vasculature involved. This paper reviews the current clinical evidence on the effects of smoking foot and ankle surgery. In the trauma setting, the evidence suggests that wound complications and non-unions are significantly higher in the smoking population. In the elective setting there is a significantly increased risk of non-union in ankle and hindfoot arthrodeses in smokers. In the setting of diabetes, ulceration rate in smokers is higher and there may be a higher risk of amputation.

[PMID: 33579625 DOI: 10.1016/j.ijom.2021.01.006] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2020] [Revised: 10/21/2020] [Accepted: 01/18/2021] [Indexed: 11/23/2022]
Abstract
A cross-sectional, nationwide survey was conducted in Japan to examine the relationship between tobacco smoking and oral diseases including implant failure. A questionnaire survey was sent to designated facilities by post, and 158 answered questions regarding implant loss. Smoking status, number of implant failures, and other related variables were collected from the participating dentists as secondary data. A total of 1966 patients who were treated with dental implants by participating dentists during the survey period were analysed. Among the total sample, 90 (5%) had early implant loss (≤12 months) and 153 (8%) had late implant loss (>12 months and ≤120 months). The number of pack-years was significantly higher in the total (early and late) implant loss group (31.2±15.9) than in the group with no implant loss (26.1±18.1) (P=0.026). In the multivariate analysis, the number of implants installed, smoking, and pack-years were significant factors for total implant loss. The adjusted odds ratio for implant failure for current smokers compared with never smokers was 2.07 (95% CI 1.19-3.62) for early implant loss and 1.48 (95% CI 0.92-2.37) for late implant loss. This study reaffirms that current smoking is associated with an increased risk of early implant loss, irrespective of the duration of smoking exposure.

J Arthroplasty 2021; 36:542-549.e3. [PMID: 32888752 DOI: 10.1016/j.arth.2020.08.003] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/11/2020] [Revised: 07/28/2020] [Accepted: 08/02/2020] [Indexed: 02/02/2023] Open
Abstract
BACKGROUND Calcium and vitamin D have been regarded as beneficial nutrients for bone metabolism that may affect survival of arthroplasties. However, the relationship between their use and revision rate of knee arthroplasty has not been evaluated. Thus, we investigated an association between calcium and vitamin D use and the revision rate after primary total knee arthroplasty. METHODS A nationwide population-based cohort study was conducted using the Korean National Health Insurance database. We included patients diagnosed with knee osteoarthritis and underwent primary total knee arthroplasty between 2009 and 2018. Risk for arthroplasty revision was estimated using a Cox proportional hazards model with time-dependent covariates. Log-rank test was used to assess survival of knee arthroplasty. RESULTS Out of 142,147 subjects, 28,403 were calcium and vitamin D users and 113,744 were never users. Calcium and vitamin D significantly reduced the revision risk with a 6-month drug use lag period (adjusted hazard ratio [aHR] 0.56, 95% confidence interval [CI] 0.45-0.70). Calcium and vitamin D combination use for more than 1 year was associated with reduced revision risks in both patients with periprosthetic joint infection (aHR 0.63, 95% CI 0.42-0.95) and patients without infection (aHR 0.70, 95% CI 0.54-0.91). Implant survival was significantly improved in calcium and vitamin D combination users for more than 1 year compared with never users (log-rank P < .001). CONCLUSION Combination use of calcium and vitamin D with a dose of 800 IU or greater for more than 1 year was associated with the greatest reduction in the risks for revision surgery after total knee arthroplasty.

Abstract
BACKGROUND No evidence is currently available to estimate the outcomes of intensity-modulated radiation therapy (IMRT) and surgery for patients with early oral cavity squamous cell carcinoma (E-OCSCC). METHODS We recruited patients from the Taiwan Cancer Registry Database who had received a diagnosis of E-OCSCC. Propensity score matching was performed, and Cox proportional hazards model was used to analyze all-cause mortality. RESULTS In the multivariate Cox regression analyses, the adjusted hazard ratio (aHR) (95% confidence interval [CI]) for surgery compared with definitive IMRT, T2N0M0 compared with T1N0M0, and male patients compared with female patients were 0.303 (0.245, 0.375), 1.340 (1.077, 1.668), and 2.012 (1.432, 2.826), respectively. The aHRs (95% CIs) for age 61 to 70, 71 to 80, and ≧81 years compared with <40 years were 2.984 (1.43, 4.225), 3.353 (2.578, 4.112), and 4.277 (4.104, 5.679), respectively. CONCLUSIONS For patients with E-OCSCC, surgery may be considered the first option rather than definitive IMRT.

Abstract
Background and purpose - Feedback programs relating to surgeon levels have been introduced in some orthopedic quality registers around the globe. The aim of an established surgeon feedback program is to help surgeons understand their practice and enable an analysis of their own results. There is no surgeon feedback program in Sweden in the orthopedic quality registers and there is a fear that a feedback system might pinpoint surgeons as poor performers, partly due to patient case mix. As a step prior to the introduction of a future possible feedback program in Sweden, we assessed the variation in the occurrence of adverse events (AE) within 90 days and reoperations within 2 years between surgeons in western Sweden and explored the number of surgeons outside the control-limit following primary total hip arthroplasties (THAs).Patients and methods - Patient data, surgical data, and information on the surgeons, relating to surgeries performed in 2011-2016, were retrieved from 9 publicly funded hospitals in western Sweden. Data from medical hospital records, the Swedish Hip Arthroplasty Register (SHAR) and a regional patient register located in western Sweden were linked to a database. Funnel plots with control-limits based on upper 95% and 99.8% confidence intervals (CI) were used to illustrate the variation between surgeons in terms of the outcome and to explore the number of surgeons outside the control-limit. Both observed and standardized proportions are explored. The definition of surgeons outside the control-limit in the study is a surgeon above the upper 95% CI.Results - The study comprised 9,482 primary THAs due to osteoarthritis performed by 208 surgeons, where 91% of the included primary THAs were performed by orthopedic specialists and 9% by trainees. The mean overall annual volume for all surgeons was 27. The observed overall mean rate for AEs within 90 days for all surgeons was 6.2% (5.8-6.7) and for reoperations within 2 years 1.8% (1.7-2.2). The proportion of surgeons outside the 95% CI was low for both AEs (0-5%) and reoperations within 2 years (0-1%) in 2011-2016. The corresponding numbers were even lower for AEs (0-3%) but similar for reoperations (0-1%) after standardization for differences in case mix. In a sub-analysis when the number of surgeries performed was restricted to more than 10 primary THAs annually to being evaluated, almost half or more of all the surgeons were excluded from the annual analysis. The result of this restriction was that all surgeons outside the control-limit disappeared after standardization for both AEs and reoperations for all the years investigated. Considering the complete period of 6 years, less than 1% (1 high-volume surgeon for AEs and 2 high-volume surgeons for reoperations) after risk adjustments were outside the 95% CI, and no surgeons were outside the 99.8% CI.Interpretation - In a Swedish setting, the variation in surgeon performance, as measured by AEs within 90 days and reoperations within 2 years following primary THA, was small and 3% or less of the surgeons were outside the 95% CI for the investigated years after adjustments for case mix. The risk for an individual surgeon to be regarded as having poor performance when creating surgeon-specific feedback in the SHAR is very low when volume and patient risk factors are considered.

Definitive radiotherapy or surgery for early oral squamous cell carcinoma in old and very old patients: A propensity-score-matched, nationwide, population-based cohort study. Radiother Oncol 2020; 151:214-221.

Abstract
PURPOSE Although patients aged >70 years are subject to early oral cavity squamous cell carcinoma (E-OCSCC), evidence is currently lacking regarding the probable outcomes of definitive radiotherapy (RT) compared to surgery in this population. METHODS We recruited patients aged ≥70 years with a diagnosis of E-OCSCC from the Taiwan Cancer Registry Database. Propensity score matching was performed, and Cox proportional-hazards model curves were used to analyze all-cause mortality of patients at different age intervals undergoing different treatments. RESULTS The matching process yielded a final cohort of 604 patients in the definitive RT and surgery cohorts who were eligible for further analysis. These patients were classified as old (70-80 years) and very old (>80 years). In the multivariate Cox regression analysis, the adjusted hazard ratio (aHR) (95% confidence interval [CI]) for surgery compared with definitive RT was 0.465 (0.354-0.610, P < 0.001). The aHR (95% CI) for age >80 years compared with age 70-80 years was 2.370 (1.720, 3.265, P < 0.001). The aHR (95% CI) for T2N0M0 compared with T1N0M0 was 1.752 (1.321-2.32, P < 0.001). The aHR (95% CI) for Charlson Comorbidity Index (CCI) ≥ 2 compared with CCI = 0 was 1.264 (1.137-1.738, P = 0.011). After stratified analysis, the aHRs for surgery compared with definitive RT were 0.484 (0.352-0.665, P < 0.001) and 0.411 (0.232-0.728, P = 0.002) among old and very old patients with E-OCSCC, respectively. CONCLUSIONS Surgery may be more beneficial than definitive RT in selected elderly patients with E-OCSCC.

Assessment of tobacco heating system 2.4 on osteogenic differentiation of mesenchymal stem cells and primary human osteoblasts compared to conventional cigarettes. World J Stem Cells 2020; 12:841-856. [PMID: 32952862 PMCID: PMC7477651 DOI: 10.4252/wjsc.v12.i8.841] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2020] [Revised: 07/17/2020] [Accepted: 08/01/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Cigarette smoking (CS) is the most common method of consuming tobacco. Deleterious effects on bone integrity, increased incidence of fractures, and delayed fracture healing are all associated with CS. Over 150 of the 6500 molecular species contained in cigarette smoke and identified as toxic compounds are inhaled by CS and, via the bloodstream, reach the skeletal system. New technologies designed to develop a reduced-risk alternative for smokers are based on electronic nicotine delivery systems, such as e-cigarettes and tobacco heating systems (THS). THS are designed to heat tobacco instead of burning it, thereby reducing the levels of harmful toxic compounds released.
AIM To examine the effects of THS on osteoprogenitor cell viability and function compared to conventional CS.
METHODS Human immortalized mesenchymal stem cells (n = 3) and primary human pre-osteoblasts isolated from cancellous bone samples from BG Unfall Klinik Tübingen (n = 5) were osteogenically differentiated in vitro with aqueous extracts generated from either the THS 2.4 “IQOS” or conventional “Marlboro” cigarettes for up to 21 d. Cell viability was analyzed using resazurin conversion assay (mitochondrial activity) and calcein-AM staining (esterase activity). Osteogenic differentiation and bone cell function were evaluated using alkaline phosphatase (AP) activity, while matrix formation was analyzed through alizarin red staining. Primary cilia structure was examined by acetylated α-tubulin immunofluorescent staining. Free radical production was evaluated with 2’,7’-dichlorofluorescein-diacetate assay.
RESULTS Our data clearly show that THS is significantly less toxic to bone cells than CS when analyzed by mitochondrial and esterase activity (P < 0.001). No significant differences in cytotoxicity between the diverse flavors of THS were observed. Harmful effects from THS on bone cell function were observed only at very high, non-physiological concentrations. In contrast, extracts from conventional cigarettes significantly reduced the AP activity (by two-fold) and matrix mineralization (four-fold) at low concentrations. Additionally, morphologic analysis of primary cilia revealed no significant changes in the length of the organelle involved in osteogenesis of osteoprogenitor cells, nor in the number of ciliated cells following THS treatment. Assessment of free radical production demonstrated that THS induced significantly less oxidative stress than conventional CS in osteoprogenitor cells.
CONCLUSION THS was significantly less harmful to osteoprogenitor cells during osteogenesis than conventional CS. Additional studies are required to confirm whether THS is a better alternative for smokers to improve delays in bone healing following fracture.

Abstract
BACKGROUND There is sparsity of data on outcomes following joint arthroplasty among polycythemia vera (PV) patients. The aim of this study is to evaluate postoperative outcomes following primary total knee (TKA) and hip (THA) arthroplasty among PV patients. METHODS A retrospective Medicare database review identified 6932 PV patients who underwent a primary total joint arthroplasty (4643 TKAs and 2289 THAs) from 2006 to 2013. A comparison of hospital length of stay, mortality, and the diagnosis of surgical site infections (SSIs), stroke, myocardial infarction, acute pulmonary embolism (PE), deep vein thrombosis (DVT), and other postoperative complications was made between PV patients undergoing TKA and THA and their respective matched control groups. RESULTS PV was significantly associated with increased rates of acute PE (2.3% vs 1.6%; odds ratio [OR] 1.44, 95% confidence interval [CI] 1.17-1.75), DVT (4.2% vs 3.6%; OR 1.40, 95% CI 1.20-1.61, P < .001), postoperative hematoma (0.6% vs 0.4%; OR 1.57, 95% CI 1.03-2.28), and SSI (4.5% vs 3.6%; OR 1.25, 95% CI 1.08-1.44, P = .002) following TKA. Among PV patients who underwent a primary THA, PV was significantly associated with increased rate of acute PE (1.9% vs 1.4%; OR 1.40, 95% CI 1.01-1.88, P = .035), DVT (3.5% vs 2.6%; OR 1.32, 95% CI 1.04-1.66, P = .035), postoperative hematoma (1.1% vs 0.6%; OR 1.86, 95% CI 1.22-2.80), and 1-year mortality (2.2% vs 1.6%; OR 1.43, 95% CI 1.06-1.89, P = .016). CONCLUSION PV was significantly associated with increased risk for DVT, PE, postoperative hematoma, SSI (TKA only), and 1-year mortality (THA only) following primary total joint arthroplasty.

Abstract
BACKGROUND The purpose of this study was to determine the influence of current and former tobacco use on minimum 2-year clinical and radiographic outcomes after reverse total shoulder arthroplasty (RTSA). METHODS Review of primary RTSA patient data identified 186 patients with at least 2 years of follow-up. Patients were classified as nonsmokers (76 patients), former smokers (89 patients), or current smokers (21 patients). Assessment included preoperative and postoperative visual analog scale pain scores, American Shoulder and Elbow Surgeons scores, strength, range of motion, complications, revisions, and narcotic use. Radiographs were analyzed for signs of loosening or mechanical failure. RESULTS Overall mean age of the patients was 70 (48-87) years, and mean follow-up was 2.6 (2.0-5.7) years. Smokers (62.1 years) were significantly younger than nonsmokers (70.7 years) and former smokers (70.8 years; P = .00002). All patients had significant improvements in pain, American Shoulder and Elbow Surgeons score, strength, and forward flexion range of motion; however, smokers had higher visual analog scale pain scores (mean, 2.5) than nonsmokers (mean, 1.8) or former smokers (mean, 1.0; P = .014). Otherwise, no differences were found regarding any of the postoperative parameters (P > .05). CONCLUSIONS Aside from increased patient-reported pain, current tobacco use does not appear to negatively affect outcomes after primary RTSA. The RTSA design obviates the need for a functioning rotator cuff, possibly mitigating tobacco's negative effects previously demonstrated in rotator cuff repair and anatomic total shoulder arthroplasty. Former users obtained outcomes similar to those of nonusers, suggesting that tobacco use is a modifiable risk factor to achieve optimal pain relief after RTSA.

Abstract
The purpose of this study was to compare wound complication rates after total ankle replacement in 3 groups of patients based on tobacco status. The total cohort was divided into 3 groups based on tobacco history. Group 1 included patients who were actively tobacco users. Group 2 included patients with a history of tobacco user. Group 3 served as the control group and included patients who had never used tobacco. Available charts were reviewed for patients who underwent primary total ankle arthroplasty by 1 surgeon. Patient demographics, tobacco history, and postoperative wound complications were recorded. A total of 114 patients with tobacco history were available for follow-up and were included in this study, which ranged from March 2012 to July 2017. Group 1 included 11 active smokers. Group 2 included 38 former smokers, and group 3 had a total of 65 never smokers included. The average follow-up was 28 months for group 1 (range 10-55 months), 34.1 months for group 2 (range 12-60 months), and 32.8 months for group 3 (range 11-60 months). The wound complication rate was noted to be statistically significant when comparing active smokers to never smokers using Fisher's exact test (P = .0223). When comparing former smokers with never smokers, the difference in wound complication rate did not reach statistical significance (P = 0.7631). All patients underwent at least 1 concomitant procedure at the time of initial ankle replacement. Our findings show that total ankle replacement wound healing complication rates are significantly higher in active tobacco users. There was no significant difference in wound healing complications when comparing former tobacco users versus never tobacco users. Levels of Evidence: Level III: Retrospective comparative study.

Abstract
Background and purpose - Smoking is a modifiable risk factor that may adversely affect postoperative outcomes. Healthcare providers are increasingly denying smokers access to total hip and knee arthroplasty (THA and TKA) until they stop smoking. Evidence supporting this is unclear. We assessed the effect of smoking on outcomes following arthroplasty.Patients and methods - We identified THAs and TKAs from the Clinical Practice Research Datalink, which were linked with datasets from Hospital Episode Statistics and the Office for National Statistics to identify outcomes. The effect of smoking on postoperative outcomes (complications, medications, revision, mortality, patient-reported outcome measures [PROMs]) was assessed using adjusted regression models.Results - We studied 60,812 THAs and 56,212 TKAs (11% smokers, 33% ex-smokers, 57% non-smokers). Following THA, smokers had an increased risk of lower respiratory tract infection (LRTI) and myocardial infarction compared with non-smokers and ex-smokers. Following TKA, smokers had an increased risk of LRTI compared with non-smokers. Compared with non-smokers (THA relative risk ratio [RRR] = 0.65; 95% CI = 0.61-0.69; TKA RRR = 0.82; CI = 0.78-0.86) and ex-smokers (THR RRR = 0.90; CI = 0.84-0.95), smokers had increased opioid usage 1-year postoperatively. Similar patterns were observed for weak opioids, paracetamol, and gabapentinoids. 1-year mortality rates were higher in smokers compared with non-smokers (THA hazard ratio [HR] = 0.37, CI = 0.29-0.49; TKA HR = 0.52, CI = 0.34-0.81) and ex-smokers (THA HR = 0.53, CI = 0.40-0.70). Long-term revision rates were not increased in smokers. Smokers had improvement in PROMs compared with preoperatively, with no clinically important difference in postoperative PROMs between smokers, non-smokers, and ex-smokers.Interpretation - Smoking is associated with more medical complications, higher analgesia usage, and increased mortality following arthroplasty. Most adverse outcomes were reduced in ex-smokers, therefore smoking cessation should be encouraged before arthroplasty.
