Abstract
OBJECTIVE To assess the impact of diabetes on physical and mental health status, as well as patient satisfaction, one-year following knee and hip total joint arthroplasty (TJA) for osteoarthritis (OA). METHODS Participants were 626 hip and 754 knee TJA patients. Pre-surgery data were collected on socio-demographics and health status. The 12-item Short Form Health Survey (SF-12) was collected pre- and one year post-surgery, and physical (PCS) and mental component (MCS) summary scores computed. One-year patient satisfaction was also recorded. Four regression models tested the effect of diabetes on: 1) PCS change score; 2) MCS change score; 3) achieving minimal clinically important improvement (MCII) on PCS; and 4) patient satisfaction ('Somewhat or Very Satisfied' vs. 'Somewhat or Very Dissatisfied'). An interaction between surgical joint and diabetes was tested in each model. RESULTS Self-reported diabetes prevalence was 13.0% (95% CI: 11.2%-14.7%) and was more common in knee 16.1% (95% CI: 13.4%-18.7%) than hip 9.3% (95% CI: 7.0%-11.5%) patients. In adjusted analyses, change scores were 2.3 units less on the PCS for those with diabetes compared to those without (p = 0.005). Patients with diabetes were about half as likely to achieve MCII as patients without diabetes (p = 0.004). Diabetes was not significantly associated with satisfaction or changes in MCS scores. Diabetes effects did not differ by surgical joint. CONCLUSIONS Findings support that diabetes has a negative impact on improvements in physical health after TJA. Considering the growing prevalence of OA and diabetes in the population, our findings support the importance of perioperative screening and management of diabetes in patients undergoing TJA.

Abstract
The objective of this review is to provide an overview of the current status of osteoarthritis (OA) as one of the most common joint disorders worldwide. Despite being the 11th cause of disability globally, there has been an increase in the prevalence, annual incidence, and years lived with disability of OA, particularly in developed and developing countries. Erosive hand OA, which affects approximately 10% of the general population, has been associated with a higher clinical burden compared to non-erosive hand OA. Patients with knee and hip OA, but not hand OA, are also at an increased risk of cardiovascular disease and all-cause mortality. Furthermore, OA has a significant contribution to healthcare costs in most countries. The recent COVID-19 pandemic has further exacerbated the disease burden of OA patients due to limited access to medical and surgical treatment. With increasing life expectancy and the aging of the global population, the burden of OA is expected to worsen. Therefore, this review highlights the importance of improving population and policymaker awareness of risk factors, such as obesity and injury, as well as early intervention and management of OA to control the future burden of the disease.

Abstract
OBJECTIVE To examine the magnitude and costs of ambulatory primary and specialist physician care and hospital service use for musculoskeletal disorders (MSDs) in Canada's largest province, Ontario. METHODS Administrative health databases were analyzed for fiscal year 2013-2014 for adults 18+ years, including data on physician services, emergency department (ED) visits and hospitalizations. ICD diagnostic codes were used to identify MSD services. A validated algorithm was used to estimate direct medical costs. Person visit rates and numbers of persons and visits were tabulated by care setting, age and sex, and physician specialty. Data were examined for all MSDs combined as well as specific diagnostic groupings. RESULTS Overall, 3.1 million adult Ontarians (28.5%) made 8 million outpatient physician visits associated with MSDs. These included 5.6 million primary care visits. MSDs accounted for 560,000, 12.3%, of all adult ED visits. Total costs for MSD-related care were $1.6 billion, with 12.6% of costs attributed to primary care, 9.2% to specialist care, 8.6% to ED care, 8.5% to day surgery and 61.2% of total costs associated with inpatient hospitalizations. Costs due to arthritis accounted for 40% of total MSD care costs ($639 million). MSD-related imaging costs were $169 million. Including these costs yields a total estimate of $1.8 billion for all MSDs combined. CONCLUSION MSDs place a significant and costly burden on the health care system. Health system planning needs to consider the large and escalating demand for care to reduce both the individual and population burden.

Abstract
INTRODUCTION The association between obesity and physical activity level is well established in the literature, as well as its consequences that lead to chronic noncommunicable diseases. In addition, it is also possible to obtain the immunometabolic mechanism that explains the pathway of associations between obesity, chronic noncommunicable diseases and the level of physical activity. It also seems clear that treating illnesses has a financial impact on healthcare systems around the world, so it seems important to assess the financial impact on the healthcare system of individuals with immunometabolic dysfunction. AIM This study aimed to assess whether there is a correlation between metabolic and inflammatory markers and healthcare costs according to body adiposity and habitual physical activity (HPA). METHODS This is a cross-sectional study, where the sample includes men and women aged over 50. Participants underwent evaluations that included the following variables: i) immunometabolic markers, ii) healthcare costs, iii) obesity, iv) habitual physical activity, and v) history of personal illness. Statistical significance was set at values lower than 5% and the software used was BioEstat. RESULTS The correlation between metabolic and inflammatory markers and healthcare costs demonstrated a positive and significant relationship, adjusted for obesity and HPA, between glucose concentrations and exam costs (r = 0.343, p-value = 0.007) and total cost (r = 261; p-value = 0.043); HOMA index and cost of exams (r = 0.267; pvalue = 0.038); and IL-10 and cost of medical consultation (r = 0.297; p-value = 0.020). CONCLUSION Metabolic and inflammatory markers may be related to the costs of consultations and examinations, independent of obesity and HPA.

Abstract
BACKGROUND Limiting treatment to those recommended by the American Academy of Orthopaedic Surgeon Clinical Practice Guidelines has been suggested to decrease costs by 45% in the year prior to total knee arthroplasty, but this only focuses on expenditures leading up to, but not including, the surgery and not the entire episode of care. We evaluated the treatment costs following knee osteoarthritis (OA) diagnosis and determined whether these are different for patients who use intra-articular hyaluronic acid (HA) and/or knee arthroplasty. METHODS Claims data from a large commercial database containing de-identified data of more than 100 million patients with continuous coverage from 2012 to 2016 was used to evaluate the cumulative cost of care for over 2 million de-identified members with knee OA over a 4.5-year period between 2011 and 2015. Median cumulative costs were then stratified for patients with or without HA and/or knee arthroplasty. RESULTS Knee OA treatment costs for 1,567,024 patients over the 4.5-year period was $6.60 billion (mean $4210/patient) as calculated by the authors. HA and knee arthroplasty accounted for 3.0 and 61.5% of the overall costs, respectively. For patients who underwent knee arthroplasty, a spike in median costs occurred sooner for patients without HA use (around the 5- to 6-month time point) compared to patients treated with HA (around the 16- to 17-month time point). CONCLUSIONS Non-arthroplasty therapies, as calculated by the authors, accounted for about one third of the costs in treating knee OA in our cohort. Although some have theorized that limiting the use of HA may reduce the costs of OA treatment, HA only comprised a small fraction (3%) of the overall costs. Among patients who underwent knee arthroplasty, those treated with HA experienced elevated costs from the surgery later than those without HA, which reflects their longer time to undergoing knee arthroplasty. The ability to delay or avoid knee arthroplasty altogether can have a substantial impact on the cost to the healthcare system.

Abstract
OBJECTIVE The influence of sex on post-total knee arthroplasty (TKA) outcomes has been variable in the literature. Though sex is often reported as an averaged effect, we undertook this study to investigate whether sex modified the influence of presurgery characteristics on post-TKA knee pain. METHODS This was a prospective study with data derived from 477 TKA osteoarthritis patients (279 women, 198 men). Questionnaires were completed presurgery and at 3 months postsurgery. The association between 3-month post-TKA knee pain and presurgery covariates (body mass index, comorbidity count, symptomatic joint count, low back pain, knee pain, and depressive symptoms) was assessed by linear regression. Sex-specific effects were evaluated using interactions. RESULTS Women had significantly worse presurgery knee pain, joint count, and depressive symptoms, and worse postsurgery knee pain, than men. With simple covariate adjustment, no sex effect on pain was found. However, sex was found to moderate the effects of comorbidities (worse for women [P = 0.013]), presence of low back pain (worse for men [P = 0.003]), and depressive symptoms (worse for men [P < 0.001]) on postsurgery pain. Worse presurgery pain was associated with worse postsurgery pain similarly for women and men. CONCLUSION The influence of some patient factors on early post-TKA pain cannot be assumed to be the same for women and men; average effects may mask underlying associations. Results suggest a need to consider sex differences in understanding TKA outcomes, which may have important implications for prognostic tool development in TKA.

Abstract
Vitrification is a cryopreservation technique for the long-term storage of viable tissue, but the success of this technique relies on multiple factors. In 2012, our group published a working vitrification protocol for intact human articular cartilage and reported promising chondrocyte recovery after using a four-step multi-cryoprotectant (CPA) loading method that required 570 min. However, this protocol requires further optimization for clinical practice. Herein, we compared three multi-step CPA loading protocols to investigate their impact on chondrocyte recovery after vitrification of porcine articular cartilage on a bone base, including our previous four-step protocol (original: 570 min), and two shorter three-step protocols (optimized: 420 min, and minimally vitrifiable: 310 min). Four different CPAs were used including glycerol, dimethyl sulfoxide, ethylene glycol and propylene glycol. As vitrification containers, two conical tubes (50 ml and 15 ml) were evaluated for their heat transfer impact on chondrocyte recovery after vitrification. Osteochondral dowels were cored into two diameters of 10.0 mm and 6.9 mm with an approximately 10-mm thick bone base, and then allocated into the twelve experimental groups based on CPA loading protocol, osteochondral dowel size, and vitrification container size. After vitrification at -196 °C and tissue warming and CPA removal, samples in all groups were assessed for both chondrocyte viability and metabolic activity. The optimized protocol proposed based on mathematical modelling resulted in similar chondrocyte recovery to our original protocol and it was 150 min shorter. Furthermore, this study illustrated the role of CPA permeation (dowel size) and heat transfer (container size) on vitrification protocol outcome.

Abstract
PURPOSE OF REVIEW The purpose of this review is to highlight recent studies of osteoarthritis epidemiology, including research on prevalence, disease impact, and potential risk factors. RECENT FINDINGS Osteoarthritis is highly prevalent in the United States and around the globe. It is a leading cause of disability and can negatively impact people's physical and mental well being. Healthcare resources and costs associated with managing the disease can be substantial. There is increasing evidence that there are different osteoarthritis phenotypes that reflect different mechanisms of the disease. Various person-level risk factors are recognized, including sociodemographic characteristics (e.g. female sex, African-American race), genetic predispositions, obesity, diet-related factors, and high bone density/mass. Joint-level risk factors include specific bone/joint shapes, thigh flexor muscle weakness, joint malalignment, participation in certain occupational/sports activities, and joint injury. Recent studies have enhanced our understanding of preradiographic lesions associated with osteoarthritis. SUMMARY Application of these new findings may allow us to develop innovative strategies and novel therapies with the purpose of preventing new disease onset and minimizing disease progression.

Abstract
AIMS The purpose of this study is to determine if higher volume hospitals have lower costs in revision hip and knee arthroplasty. MATERIALS AND METHODS We questioned the Centres for Medicare and Medicaid Services (CMS) Inpatient Charge Data and identified 789 hospitals performing a total of 29 580 revision arthroplasties in 2014. Centres were dichotomised into high-volume (performing over 50 revision cases per year) and low-volume. Mean total hospital-specific charges and inpatient payments were obtained from the database and stratified based on Diagnosis Related Group (DRG) codes. Patient satisfaction scores were obtained from the multiyear CMS Hospital Compare database. RESULTS High-volume hospitals comprised 178 (30%) of the total but performed 15 068 (51%) of all revision cases, including 509 of 522 (98%) of the most complex DRG 466 cases. While high-volume hospitals had higher Medicare inpatient payments for DRG 467 ($21 458 versus $20 632, p = 0.038) and DRG 468 ($17 003 versus $16 120, p = 0.011), there was no difference in hospital specific charges between the groups. Higher-volume facilities had a better CMS hospital star rating (3.63 versus 3.35, p < 0.001). When controlling for hospital geographic and demographic factors, high-volume revision hospitals are less likely to be in the upper quartile of inpatient Medicare costs for DRG 467 (odds ratio (OR) 0.593, 95% confidence intervals (CI) 0.374 to 0.941, p = 0.026) and DRG 468 (OR 0.451, 95% CI 0.297 to 0.687, p < 0.001). CONCLUSION While a high-volume hospital is less likely to be a high cost outlier, the higher mean Medicare reimbursements at these facilities may be due to increased case complexity. Further study should focus on measures for cost savings in revision total joint arthroplasties. Cite this article: Bone Joint J 2017;99-B:1611-17.
