Autologous Micro-Fragmented Adipose Tissue (MFAT) to Treat Symptomatic Knee Osteoarthritis: Early Outcomes of a Consecutive Case Series. J Clin Med 2021; 10:jcm10112231. [PMID: 34064010 PMCID: PMC8196751 DOI: 10.3390/jcm10112231] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2021] [Revised: 05/13/2021] [Accepted: 05/19/2021] [Indexed: 12/16/2022] Open
Abstract
The study aimed to evaluate the short-term clinical effect, therapeutic response rate (TRR%), and therapy safety of a single intra-articular autologous MFAT injection for symptomatic knee OA. Secondly, patient- and pathology-related parameters were investigated to tighten patient selection for MFAT therapy. Sixty-four subjects with symptomatic mild–severe knee OA were enrolled in a single-center trial and received a unilateral (n = 37) or bilateral (n = 27) MFAT injection. After liposuction, the adipose tissue was mechanically processed with the Lipogem® device, which eventually produced 8–10 cc of MFAT. Subjects were clinically assessed by means of the KOOS, NRS, UCLA, and EQ-5D at baseline and 1, 3, 6, and 12 months after injection. Adverse events were recorded at each follow-up timepoint. The TRR was defined according to the OMERACT-OARSI criteria and baseline MRI was scored following the MOAKS classification. The TRR of the index knee was 64% at 3 months and 45% at 12 months after injection. Therapy responders at 12 months improved with 28.3 ± 11.4 on KOOS pain, while non-responders lost −2.1 ± 11.2 points. All clinical scores, except the UCLA, improved significantly at follow-up compared to baseline (p < 0.05). In the bilateral cohort, no difference in baseline scores or TRR was found between the index knee and contralateral knee (n.s.). An inflammatory reaction was reported in 79% of knees and resolved spontaneously within 16.6 ± 13.5 days after MFAT administration. Numerous bone marrow lesions (BML) were negatively correlated with the TRR at 12 months (p = 0.003). The study demonstrated an early clinical improvement but a mediocre response rate of 45% at 12 months after a single intra-articular injection with autologous MFAT. Assessment of bone marrow lesions on MRI can be helpful to increase the therapeutic responsiveness of MFAT up to 70% at 12 months. In comparison to repetitive injection therapies such as cortisone, hyaluronic acid, and PRP, administration of MFAT might become a relevant alternative in well-selected patients with symptomatic knee OA.

Characterizing the alkaptonuria joint and spine phenotype and assessing the effect of homogentisic acid lowering therapy in a large cohort of 87 patients. J Inherit Metab Dis 2021; 44:666-676. [PMID: 33452825 DOI: 10.1002/jimd.12363] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/27/2020] [Revised: 01/07/2021] [Accepted: 01/13/2021] [Indexed: 01/18/2023]
Abstract
A large alkaptonuria (AKU) cohort was studied to better characterize the poorly understood spondyloarthropathy of rare disease AKU. Eighty-seven patients attended the National Alkaptonuria Centre (NAC) between 2007 and 2020. Seven only attended once. Fifty-seven attended more than once and received nitisinone 2 mg daily. Twenty-three attended at least twice without receiving nitisinone. Assessments included questionnaire analysis, 18F Positron emission tomography computerised tomography (PETCT), as well as photographs of ochronotic pigment in eyes and ears at baseline when 2 mg nitisinone was commenced and yearly thereafter. Blood and urine samples were collected for chemical measurement. The prevalence of ochronosis, as well as pain, PETCT and combined pain and PETCT scores, was greatly increased at 90.5%, 85.7%, 100%, and 100%, respectively. Joint pain scores were greatest in proximal joints in upper and lower limbs. PETCT joint scores were higher in proximal joints in upper limb but higher in distal joints in the lower limb. Spine pain scores were highest in lumbar, followed by cervical, thoracic, and cervical regions at 77.4%, 59.5%, 46.4%, and 25%, respectively. PETCT spine scores were highest in thoracic followed by lumbar, cervical, and sacroiliac regions at 74.4%, 70.7%, 64.6%, and 47.8% respectively; ochronosis associated closely with spondyloarthropathy scores (R = .65; P < .0001). Nitisinone reversed ochronosis significantly, with a similar pattern of decreased joint and spine disease. Spondyloarthropathy is a highly prevalent feature in this NAC cohort. Ochronosis appears to be associated with spondyloarthropathy. Nitisinone decreases ochronosis and had a similar nonsignificant effect pattern on spondyloarthropathy.

Abstract
PURPOSE To study differences between men and women in physical activity (PA) and health-related quality of life (HRQoL) before and after participating in a supported osteoarthritis (OA) self-management programme. MATERIALS AND METHODS A prospective observational study using data from a Swedish National Quality Register. Patients recorded between 2008 and 2013 with hip and/or knee OA with data at baseline, at 3 and 12 months follow-up (n = 7628) were included. Outcome measures were patient-reported PA and HRQoL (EQ-5D-3L). RESULTS A greater proportion of men (p = 0.002) changed to being physically active ≥150 min/week at 3 months follow-up. The proportion of women being physically active ≥150 min/week was larger than for men at baseline (p = 0.003) and at follow-up at 12 months (p = 0.035). Women reported lower HRQoL than men at baseline (p < 0.001), at follow-up at 3 (p < 0.001) and 12 months (p = 0.010). There were no differences between men and women in change in HRQoL at 3 (p = 0.629) and 12 months (p = 0.577) follow-up. CONCLUSIONS This study showed differences between men and women in PA and HRQoL before and after participating in a supported OA self-management programme. These differences should be considered when supporting PA and HRQoL.Implications for rehabilitationMen with hip and/or knee osteoarthritis (OA) might need more support during rehabilitation in order to maintain or even increase physical activity (PA) in the long run.Women with hip and/or knee OA might need more support during rehabilitation in order to maintain or even increase health-related quality of life (HRQoL) in the long run.Booster sessions might be suggested in order to enable both men and women with hip and/or knee OA to sustain improvements in PA and HRQoL after participating in a supported OA self-management programme.

Autologous protein solution as selective treatment for advanced patellofemoral osteoarthritis in the middle-aged female patient: 54% response rate at 1 year follow-up. Knee Surg Sports Traumatol Arthrosc 2021; 29:988-997. [PMID: 32451622 DOI: 10.1007/s00167-020-06064-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/12/2020] [Accepted: 05/13/2020] [Indexed: 12/20/2022]
Abstract
PURPOSE The study wanted to investigate the benefit, durability and safety of autologous protein solution (APS) injection(s) in a middle-aged female-only cohort suffering predominantly from patellofemoral osteoarthritis. METHODS Fifty females (aged 50.4 ± 6.5) with mainly moderate-severe (86%) patellofemoral cartilage wear (PFCW) were treated with a unilateral intra-articular APS injection. The KOOS, NRS, Kujala, UCLA and EQ-5D were assessed at baseline and 1, 3, 6, and 12 months post-injection. Therapeutic response rate (TRR) was based on KOOS pain improvement > 10 points. Absolute improvement for, respectively, therapy responders and non-responders was determined. Second APS injection was administered if improvement was deemed insufficient by the patient after 3 months. RESULTS The TRR remained stable averaging to 53.7% at final follow-up with subjects improving overall from 40.3 ± 18.7 to 57.3 ± 24.8 points on KOOS pain (p = 0.0002) and from 48.4 ± 13.0 to 56.3 ± 18.1 points on Kujala (p = 0.0203) at 12 months. Significant improvement was observed for the other KOOS subscales and NRS at each follow-up. In absolute values, APS responders improved with 30.5 ± 11.4 points on KOOS pain at 12 months. In contrast, non-responders deteriorated with 5.9 ± 8.9 points relative to baseline. A second APS injection was administered in 28 subjects. Patients with definite synovitis improved more on KOOS symptoms (p = 0.017) and KOOS ADL (p = 0.037) at 12 months compared to non-synovitis subjects. Mild-moderate arthralgia (46%) and effusion (29%) were commonly observed during the first month post-injection. CONCLUSION This study evidenced a 54% response rate at 12 months to a single or second APS injection in a middle-aged female population with advanced patellofemoral cartilage wear. Moderate temporary flares can be expected without affecting clinical outcomes. Second APS injection has low efficacy in initially poor responding patients after 3 months. Major synovitis on baseline MRI appeared to be a beneficial prognosticator for pain relief and functional improvement after APS. LEVEL OF EVIDENCE IV.

Cross-Sectional Association between Hypercholesterolemia and Knee Pain in the Elderly with Radiographic Knee Osteoarthritis: Data from the Korean National Health and Nutritional Examination Survey. J Clin Med 2021; 10:jcm10050933. [PMID: 33804313 PMCID: PMC7957475 DOI: 10.3390/jcm10050933] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2021] [Revised: 02/16/2021] [Accepted: 02/18/2021] [Indexed: 11/17/2022] Open
Abstract
Few studies have reported the relationship between knee pain and hypercholesterolemia in the elderly population with osteoarthritis (OA), independent of other variables. The aim of this study was to reveal the association between knee pain and metabolic diseases including hypercholesterolemia using a large-scale cohort. A cross-sectional study was conducted using data from the Korea National Health and the Nutrition Examination Survey (KNHANES-V, VI-1; 2010-2013). Among the subjects aged ≥60 years, 7438 subjects (weighted number estimate = 35,524,307) who replied knee pain item and performed the simple radiographs of knee were enrolled. Using multivariable ordinal logistic regression analysis, variables affecting knee pain were identified, and the odds ratio (OR) was calculated. Of the 35,524,307 subjects, 10,630,836 (29.9%) subjects experienced knee pain. Overall, 20,290,421 subjects (56.3%) had radiographic OA, and 8,119,372 (40.0%) of them complained of knee pain. Multivariable ordinal logistic regression analysis showed that among the metabolic diseases, only hypercholesterolemia was positively correlated with knee pain in the OA group (OR 1.24; 95% Confidence Interval 1.02-1.52, p = 0.033). There were no metabolic diseases correlated with knee pain in the non-OA group. This large-scale study revealed that in the elderly, hypercholesterolemia was positively associated with knee pain independent of body mass index and other metabolic diseases in the OA group, but not in the non-OA group. These results will help in understanding the nature of arthritic pain, and may support the need for exploring the longitudinal associations.

Abstract
The abnormal expression of circulating miRNAs (c-miRNAs) has become an emerging field in the development of miRNAs-based diagnostic and therapeutic tools for human diseases, including osteoarthritis (OA). OA is the most common form of arthritis leading to disability and a major socioeconomic burden. The abnormal expression of miRNAs plays important roles in the pathogenesis of OA. Unraveling the role of miRNAs in the pathogenesis of OA will throw light on the potential for the development of miRNAs-based diagnostic and therapeutic tools for OA. This article reviews and highlights recent advances in the study of miRNAs in OA, with specific demonstration of the functions of miRNA, especially c-miRNA, in OA pathogenesis as well as its potential implication in the treatment of OA. Based on a systematic literature search using online databases, we figured out the following main points: (1) the integrative systematic review of c-mRNAs and its target genes related to OA pathogenesis; (2) the potential use of c-miRNAs for OA diagnosis purposes as potential biomarkers; and (3) for therapeutic purposes, and we also highlight certain remedies that regulate microRNA expression based on its target genes.

Abstract
OBJECTIVE Perceived discrimination is associated with chronic pain and depression and contributes to racial health disparities. In a cohort of older adult veterans with osteoarthritis (OA), our objective was to examine how membership in multiple socially disadvantaged groups (cumulative disadvantage) was associated with perceived discrimination, pain, and depression. We also tested whether perceived discrimination mediated the association of cumulative disadvantage with depression and pain. METHODS We analyzed baseline data from 270 African American veterans and 247 White veterans enrolled in a randomized controlled trial testing a psychological intervention for chronic pain at 2 Department of Veterans Affairs medical centers. Participants were age ≥50 years and self-reported symptomatic knee OA. Measures included the Everyday Discrimination Scale, the Patient Health Questionnaire Depression Scale, the Western Ontario and McMaster Universities Osteoarthritis Index pain subscale, and demographic variables. Cumulative disadvantage was defined as the number of socially disadvantaged groups to which each participant belonged (i.e., self-reported female sex, African American race, annual income of <$20,000, and/or unemployed due to disability). We used linear regression models and Sobel's test of mediation to examine hypotheses. RESULTS The mean ± SD number of social disadvantages was 1.3 ± 1.0. Cumulative disadvantage was significantly associated with higher perceived discrimination, pain, and depression (P < 0.001 for all). Perceived discrimination significantly mediated the association between cumulative disadvantage and depression symptoms (Z = 3.75, P < 0.001) as well as pain severity (Z = 2.24, P = 0.025). CONCLUSION Perceived discrimination is an important psychosocial stressor that contributes to worsening OA-related mental and physical health outcomes, with greater effects among those from multiple socially disadvantaged groups.

Abstract
OBJECTIVES To investigate whether lower limb arterial calcification (LLAC) quantified using computed tomography (CT) was a risk factor for bilateral severe knee osteoarthritis (OA). METHODS This cross-sectional study included patients who were scheduled for surgical treatment of primary varus knee OA. Knee OA was evaluated using the Kellgren-Lawrence (KL) classification, KL grades 3 and 4 were defined as severe OA. The LLAC score in the bilateral whole leg CT was quantitatively measured and categorized into low or high groups based on the median value. A modified Poisson regression model was used to examine the relationship between the categorized LLAC score and the presence of bilateral severe knee OA with adjustment for possible confounders. RESULTS Of a total of 252 patients examined, multivariable modified Poisson regression analysis showed a significant association between higher LLAC score and the presence of bilateral severe knee OA (adjusted risk ratio = 1.28; 95% confidence interval [CI], 1.12-1.48; p < .001). A substantial interaction was observed between male sex and high LLAC (p for interaction = .03). CONCLUSION LLAC was associated with bilateral severe knee OA, and the LLAC score may be a useful measurement to identify patients at risk of bilateral severe knee OA.

Abstract
As the leading cause of disability, osteoarthritis (OA) affects people of all ages, sexes, and races. With the increasing understanding of OA, the sex differences have attracted specific attention as the burden of OA is greater in women. There is no doubt that gender-specific OA management has great potential for precision treatment. On the other hand, from the marketing aspect, a medication targeting the OA-responsive biomarker(s) shared by both genders is more favorable for drug development. Thus, in the current study, a published transcriptome dataset of knee articular cartilage was used to compare OA and healthy samples for identifying the genes with the same significantly different expression trend in both males and females. With 128 genes upregulated and 143 genes downregulated in both OA males and females, 9 KEGG pathways have been enriched based on the current knowledge, including 'renal cell carcinoma,' 'ECM-receptor interaction,' 'HIF-1 signaling pathway,' 'MicroRNAs in cancer,' 'focal adhesion,' 'Relaxin signaling pathway,' 'breast cancer,' 'PI3K-Akt signaling pathway,' and 'human papillomavirus infection.' Here, we explore the potential impacts of these clusters in OA. We also analyze the identified 'cell plasma membrane related genes' in-depth to identify the potential chondrocyte cell surface target(s) of OA management.

Abstract
PURPOSE This study evaluated the effectiveness of the Self-Efficacy Reinforcement Stretching Exercise Program to improve osteoarthritis (OA)-related symptoms in older women with OA. DESIGN A quasi-experimental design was used in this study. METHODS The experimental group participated in the Self-Efficacy Reinforcement Stretching Exercise Program, a 6-week program composed of stretching exercises and self-efficacy reinforcement strategies, whereas the control group did not. All participants were assessed on pain; joint stiffness; physical function disability; body mass index; depression; and quality of life at the beginning, end, and 4 weeks after the program ended. FINDINGS After participation, the experimental group had significantly less joint stiffness, physical function disability, and depression scores and significantly higher self-efficacy and quality of life than the control group. CONCLUSIONS This intervention program led to an improvement in OA-related symptoms, self-efficacy, and quality of life in older women with OA. CLINICAL RELEVANCE The sustained effects of acquired exercise behaviors that persisted up to 4 weeks after the program ended could be of interest to rehabilitation nurses and other healthcare professionals.

Abstract
BACKGROUND Most populations worldwide, who are used to squatting and sitting cross-legged for their activities of daily living, largely comprise the lower socioeconomic strata, thus making them candidates for exclusion for total knee arthroplasty. Proximal/high tibial osteotomy (HTO) is a preferred strategy for clinically symptomatic osteoarthritis (OA) with genu varum due to painful medial compartment OA which is not amenable to conservative measures. AIM To evaluate the outcomes of medial open-wedge HTO along with autologous bone grafting and buttress plate for the treatment of genu varum due to OA of the knee in a rural population of central India. METHODS A total of 65 knees in 56 patients with a mean age of 58.22 ± 5.63 years with genu varum due to intractable painful knee OA were treated with medial open-wedge HTO along with autologous bone grafting and buttress plate osteosynthesis from June 2015 to May 2018. The mean preoperative radiological angle of genu varum was 13.4°. Clinical outcomes were assessed by the range of movement, knee scores, pain scores, and functional scores. Radiographic studies were performed preoperatively and at regular intervals during the follow-up period. RESULTS All patients reported pain relief immediately after the osteotomy and during the long-term analysis covering between one to three years. The genu varum angle was overcorrected to approximately four degrees in all patients. There was a loss of reduction by approximately three degrees in all patients at around six weeks postoperatively. Preoperative knee movements were restored in all patients. No major perioperative complications were noted during surgery and postoperative follow-up and the clinical scores were significantly improved during the final analysis which revealed good pain relief. CONCLUSION Medial open-wedge HTO is a reliable, safe, practical, physiological, and feasible treatment for populations who are used to increased activity in their occupation and lifestyle and is associated with excellent short-term and long-term results for OA in genu varum knees.

Sex-Specific Differences in Extracellular Vesicle Protein Cargo in Synovial Fluid of Patients with Osteoarthritis. Life (Basel) 2020; 10:life10120337. [PMID: 33321751 PMCID: PMC7763294 DOI: 10.3390/life10120337] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2020] [Revised: 12/02/2020] [Accepted: 12/03/2020] [Indexed: 12/20/2022] Open
Abstract
Women are at a significantly higher risk of developing osteoarthritis (OA) compared to males. The pathogenesis of osteoarthritis (OA) in women is poorly understood. Extracellular vesicles (EVs) have been shown to play an essential role in numerous signaling processes during the pathogenesis of age-related diseases via paracrine signaling. Molecular profiling of the synovial fluid-derived EVs cargo in women may help in the discovery of novel biomarkers and therapeutics for the treatment of OA in women. Previously, we reported that synovial fluid-derived EV miRNA cargo differs in a sex-specific manner. This study aims to characterize synovial fluid-derived EV protein cargo in OA patients. Our data showed sex-specific EVs protein content in OA. We found haptoglobin, orosomucoid, and ceruloplasmin significantly up-regulated, whereas apolipoprotein down-regulated in female OA EVs. In males, we discovered β-2-glycoprotein, and complement component 5 proteins significantly up-regulated and Spt-Ada-Gcn5 acetyltransferase (SAGA)-associated factor 29 down-regulated in male OA EVs. Database for Annotation, Visualization, and Integrated Discovery (DAVID) and QuickGO analysis revealed OA-specific protein involvement in several biological, molecular, and cellular pathways, specifically in inflammatory processes. In conclusion, synovial fluid EV protein content is altered in a sex-specific manner with OA, explaining the increased prevalence and severity of OA in women.

Abstract
The nonoperative practitioner managing individuals with cartilage defects should use a patient-centered, multifaceted approach that aims to individualize treatment to provide optimal benefit. These include addressing modifiable risk factors for disease progression and instituting interventions such as weight loss, nutrition, physical activity, and potentially regenerative medicine strategies. This review will focus on these nonoperative treatment strategies with a focus on when treatments are necessary, who will benefit from these approaches, why they are specifically appropriate, and, finally, how these treatments directly modify the structure of a patient's cartilage and resulting symptoms.

Total Serum Testosterone and Western Ontario and McMaster Universities Osteoarthritis Index Pain and Function Among Older Men and Women With Severe Knee Osteoarthritis. Arthritis Care Res (Hoboken) 2020; 72:1511-1518.

Abstract
OBJECTIVE To investigate whether serum total testosterone level is associated with knee pain and function in men and women with severe knee osteoarthritis (OA). METHODS We enrolled 272 adults age ≥60 years (mean ± SD age 70.4 ± 4.4 years, 53% women) who underwent unilateral total knee replacement (TKR) due to severe knee OA. Serum testosterone levels and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain and function of the operated and contralateral knee were measured at 6-8 weeks after surgery. At the nonoperated knee, 56% of participants had radiographic knee OA with a Kellgren/Lawrence grade ≥2. Cross-sectional analyses were performed by sex and body mass index (BMI) subgroups, using multivariable regression adjusted for age, physical activity, and BMI. RESULTS At the operated knee, higher testosterone levels were associated with less WOMAC pain in men (B = -0.62, P = 0.046) and women (B = -3.79, P = 0.02), and less WOMAC disability scores in women (B = -3.62, P = 0.02) and obese men (B = -1.99, P = 0.02). At the nonoperated knee, testosterone levels were not associated with WOMAC pain in men or women, but higher testosterone levels were associated with less disability in women (B = -0.95, P = 0.02). Testosterone levels were inconsistently associated with pain and disability in BMI subgroups among men. Only among obese women, testosterone levels were inversely associated with radiographic knee OA (odds ratio = 0.10, P = 0.003). CONCLUSION Higher total testosterone levels were associated with less pain in the operated knee in men and women undergoing TKR and less disability in women. At the nonoperated knee, higher testosterone levels were inconsistently associated with less pain and disability.

Abstract
Being the most common musculoskeletal progressive condition, osteoarthritis is an interesting target for research. It is estimated that the prevalence of knee osteoarthritis (OA) among adults 60 years of age or older is approximately 10% in men and 13% in women, making knee OA one of the leading causes of disability in elderly population. Today, we know that osteoarthritis is not a disease characterized by loss of cartilage due to mechanical loading only, but a condition that affects all of the tissues in the joint, causing detectable changes in tissue architecture, its metabolism and function. All of these changes are mediated by a complex and not yet fully researched interplay of proinflammatory and anti-inflammatory cytokines, chemokines, growth factors and adipokines, all of which can be measured in the serum, synovium and histological samples, potentially serving as biomarkers of disease stage and progression. Another key aspect of disease progression is the epigenome that regulates all the genetic expression through DNA methylation, histone modifications, and mRNA interference. A lot of work has been put into developing non-surgical treatment options to slow down the natural course of osteoarthritis to postpone, or maybe even replace extensive surgeries such as total knee arthroplasty. At the moment, biological treatments such as platelet-rich plasma, bone marrow mesenchymal stem cells and autologous microfragmented adipose tissue containing stromal vascular fraction are ordinarily used. Furthermore, the latter two mentioned cell-based treatment options seem to be the only methods so far that increase the quality of cartilage in osteoarthritis patients. Yet, in the future, gene therapy could potentially become an option for orthopedic patients. In the following review, we summarized all of the latest and most important research in basic sciences, pathogenesis, and non-operative treatment.

Abstract
Aim: This study investigated the safety and clinical outcomes of expanded allogeneic human adipose-derived mesenchymal progenitor cells injected into patients with symptomatic, bilateral knee osteoarthritis. Design: In this single-site, randomized, double-blind, dose-ranging, Phase I study, patients were randomized to three treatment groups (low dose, 1 × 107 cells; medium dose, 2 × 107 cells; high dose, 5 × 107 cells). All patients received two bilateral intra-articular injections: week 0 (baseline) and week 3. The primary end point was adverse events within 48 weeks. Secondary end points were measured with Western Ontario and McMaster Universities Osteoarthritis index, visual analog scale, short form-36 at weeks 12, 24 and 48. Quantitative MRI measurements of cartilage volume were compared from baseline and week 48. Results: A total of 22 subjects were enrolled of which 19 (86%) completed the study. Adverse events were transient, including mild to moderate pain and swelling of injection site. Improvements from baseline were measured in the secondary end points. MRI assessments showed slight improvements in the low-dose group. Conclusion: Safety and improvements in pain and function after intra-articular injections of allogeneic human adipose-derived mesenchymal progenitor cells into arthritic patients was demonstrated.

Sex- and osteoarthritis-related differences in muscle co-activation during weight-bearing tasks. Gait Posture 2020; 79:117-125. [PMID: 32402893 DOI: 10.1016/j.gaitpost.2020.04.019] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/10/2019] [Revised: 04/16/2020] [Accepted: 04/18/2020] [Indexed: 02/02/2023]
Abstract
BACKGROUND Individuals with knee osteoarthritis (OA) demonstrate impairments in muscle function (i.e. muscle weakness, high muscle co-activation believed to have detrimental effects on joint integrity). Women with knee OA exhibit poorer health outcomes than men. Sex and muscle function are known risk factors for knee OA. It is unclear how these risk factors are associated with muscle function in knee OA and the implications for disease aetiology. RESEARCH QUESTION How does sex and knee osteoarthritis disease status relate to muscle function, specifically strength and muscle co-activation, during walking, stair negotiation and sit-to-walk activities. METHODS A cross-sectional study assessed muscle co-activation in 77 individuals with knee OA (mean[SD], 62.5[8.1] years; 48/29 women/men) and 18 age-matched controls (62.5[10.4] years; 9/9 women/men), during a series of walking, stair ascent and descent and sit-to-walk activities. Muscle strength of the knee extensors and flexors was assessed using maximal voluntary isometric contractions (MVIC). Electromyography was recorded from the vastus lateralis/medalis, rectus femoris, biceps femoris, semitendinosus, medial/lateral gastrocnemius normalised to MVIC. Multiple regression assessed the relationship between sex, disease status, and muscle strength on muscle co-activation. RESULTS Individuals with knee OA were weaker than controls, had higher hamstrings-quadriceps and medial-lateral co-activation for specific phases of gait. Women were weaker than men with higher muscle co-activation across all activities. Sex and muscle weakness, but not age or disease status predicted high muscle co-activation. SIGNIFICANCE High muscle co-activation was associated with female sex and muscle weakness regardless of disease status and age. High muscle co-activation is believed to be a compensatory mechanism for muscle weakness to maintain a certain level of function. High muscle co-activation is also thought to have detrimental effects on cartilage and joint integrity this may explain high muscle co-activation in women with muscle weakness and contribute to increased risk of incidence and progression of knee OA in women.

Abstract
BACKGROUND There is limited understanding of how antagonist muscle coactivation relates to measurement of strength in both individuals with and without knee osteoarthritis (KOA). OBJECTIVE This study sought to determine whether hamstring coactivation during a maximal quadriceps activation task attenuates net quadriceps strength. DESIGN Cross-sectional cohort analysis was conducted using data from the 60-month visit of the Multicenter Osteoarthritis Study (MOST). SETTING Laboratory. PARTICIPANTS A sample of 2328 community-dwelling MOST participants between the ages of 55 and 84 years, with or at elevated risk for KOA, completed the 60-month MOST follow-up visit. Of these, 1666 met inclusion criteria for the current study. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURE(S) Quadriceps strength; percentage of combined hamstring coactivation (HC), medial HC, and lateral HC. Quadriceps and hamstring strength were assessed using an isokinetic dynamometer. Surface electromyography was used to assess muscle activation patterns. General linear models, adjusted for age, BMI, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Kellgren-Lawrence (KL) grade and study site, modeled the relationship between antagonist hamstring coactivation and quadriceps strength. RESULTS Men had significantly greater quadriceps strength (P < .001), history of knee injury (P < .001) and surgery (P = .002), and greater presence of varus malalignment (P < .001). Women had greater pain (P < .001) and proportion of KL grade ≥2 (P = .017). Gender-specific analyses revealed combined HC (P = .013) and lateral HC inversely associated with quadriceps strength in women (P = .023) but not in men (combined HC P = .320, lateral HC P = .755). A nonlinear association was detected between quadriceps strength and medial HC. Assessment of quartiles of medial HC revealed the third quartile had reduced quadriceps strength when compared to the lowest quartile of coactivation in both men and women. CONCLUSIONS Hamstring coactivation attenuates measured quadriceps strength in women with or at elevated risk for KOA. LEVEL OF EVIDENCE II.

Abstract
PURPOSE The aim of this study is to explore patients' experience of pain and postoperative nausea and vomiting (PONV) in the early postoperative period after knee arthroplasties. DESIGN This is a retrospective cohort study with a quantitative approach. Data from patients registered in the Swedish Perioperative Registry were used. We used the Strenghtening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines for cross-sectional studies. METHODS Data were collected from patients (N = 439) undergoing knee arthroplasties. The analysis was performed with descriptive and analytic statistics. FINDINGS The findings indicate that women experienced significantly higher levels of pain than men and suffered significantly more often from PONV. However, the relationship of postoperative pain and PONV was not significant. There was also no significance for the relationship among postoperative pain, PONV, and age. CONCLUSIONS Care needs to be sensitive to differences in experiencing pain and PONV depending on sex or gender bias, with a goal of increasing the equality in care.

Abstract
Sex and gender influence health differently. Associations between sex and health have been extensively studied, but gender (i.e. psychosocial sex) has been largely neglected, partly due to the absence of gender measures in cohort studies. Therefore, our objective was to test the unique associations of gender and sex with common somatic symptoms and chronic diseases, using a gender index created from existing cohort data. We applied LASSO logistic regression to identify, out of 153 unique variables, psychosocial variables that were predictive of sex (i.e. gender-related) in the Dutch LifeLines Cohort Study. These psychosocial variables covered gender roles and institutionalized gender. Using the estimated coefficients, gender indexes were calculated for each adult participant in the study (n = 152,728; 58.5% female; mean age 44.6 (13.1) years). We applied multiple ordinal and logistic regression to test the unique associations of the gender index and sex, and their interactions, with common somatic symptoms assessed by the SCL-90 SOM and self-reported lifetime prevalence of chronic diseases, respectively. We found that in 10.1% of the participants the gender index was not in line with participants' sex: 12.5% of men and 8.4% of women showed a discrepancy between gender index and sex. Feminine gender characteristics are associated with increased common somatic symptoms and chronic diseases, especially in men. Female sex is associated with a higher common somatic symptom burden, but not with a higher prevalence of chronic diseases. The study shows that gender and sex uniquely impact health, and should be considered in epidemiological studies. Our methodology shows that consideration of gender measures in studies is necessary and feasible, based on data generally present in cohort studies.

Abstract
INTRODUCTION Chronic pain may cause many comorbidities in the elderly; however, nationwide data about this issue remain insufficient. We conducted this study to address the data gap. MATERIAL AND METHODS We identified geriatric participants (≥ 65 years) with chronic pain between 2000 and 2013 from the Taiwan National Health Insurance Research Database. The causes of chronic pain and use of analgesics between two sexes and among three age subgroups were compared. RESULTS A total of 21,018 participants were identified with the mean age (standard deviation) of 72.7 years (5.6) and the female percentage of 50.8%. The prevalence of chronic pain in the elderly was 21.5%, and it was higher in the females than males. The proportions of each age subgroup were 65-74 (66.8%), 75-84 (29.4%), and ≥ 85 years (3.8%). Common causes of chronic pain were osteoarthritis (21.9%), spinal disorders (19.0%), peripheral vascular diseases (12.4%), and osteoporosis (11.4%). Non-steroidal anti-inflammatory drugs were the most common medication, followed by acetaminophen and opioids. The most commonly used opioid was morphine. The use of opioids increased with age. CONCLUSIONS This study delineated the causes of chronic pain and use of analgesics in a geriatric population, which may help further studies about this issue in the future.

Ginsenoside Rb 1 inhibits monoiodoacetate-induced osteoarthritis in postmenopausal rats through prevention of cartilage degradation. J Ginseng Res 2020; 45:287-294. [PMID: 33841009 PMCID: PMC8020294 DOI: 10.1016/j.jgr.2020.01.004] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2019] [Revised: 12/23/2019] [Accepted: 01/14/2020] [Indexed: 01/15/2023] Open
Abstract
Background Ginsenoside Rb1 (G-Rb1), one of the major active compounds in Panax ginseng, has already been shown to reduce inflammation in various diseases. Osteoarthritis (OA) has traditionally been considered a degenerative disease with degradation of joint articular cartilage. However, recent studies have shown the association of inflammation with OA. In the present study, we investigated whether Rb1 had an antiinflammatory effect on monoiodoacetate (MIA)-induced OA in ovariectomized rats as a model of postmenopausal arthritis. Methods G-Rb1 at a dosage of 3 and 10 μg/kg body weight was administered every 3 days intraarticularly for a period of 4 weeks to observe antiarthritic effects. Diclofenac (10 mg/kg) served as a positive control. Results The administration of Rb1 significantly ameliorated OA inflammatory symptoms and reduced serum levels of inflammatory cytokines. Furthermore, G-Rb1 administration considerably enhanced the expression of bone morphogenetic protein-2 and collagen 2A and reduced the levels of matrix metalloproteinase-13 genes, indicating a chondroprotective effect of G-Rb1. G-Rb1 also significantly reduced the expression of several inflammatory cytokines/chemokines (interferon gamma (IFN-γ), monocyte chemoattractant protein-1 (MCP-1)/CCL-2, interleukin [IL]-1β, and IL-6). Histological analysis demonstrated that G-Rb1 significantly attenuated the pathological changes in MIA-induced OA in ovariectomized rats. Safranin O and toluidine blue staining further demonstrated that G-Rb1 effectively prevented the degradation of cartilage and glycosaminoglycans, respectively. Conclusion Overall, our results suggest that G-Rb1 exerts cartilage protective effect on MIA-induced ovariectomized OA rats, by inhibiting inflammatory mediators such as IL-6, IL-1β, MCP-1/CCL-2, cyclooxygenase-2 (COX-2), and prostaglandin E2 (PGE2). These results shed a light on possible therapeutic application of G-Rb1 in OA.

Regional differences between the US, Scandinavia, and South Korea in patient demographics and patient-reported outcomes for primary total knee arthroplasty. Arch Orthop Trauma Surg 2020; 140:93-108. [PMID: 31650229 DOI: 10.1007/s00402-019-03286-5] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/20/2019] [Indexed: 02/09/2023]
Abstract
INTRODUCTION Differences in total knee arthroplasty (TKA) patient demographics and clinical outcomes may exist between international regions, yet research is limited. The aim of this study was, therefore, to compare TKA patient demographics and patient-reported outcome measure (PROM) scores between the US, Scandinavia, and South Korea. MATERIALS AND METHODS A total of 398 TKA patients from three regions were assessed: 169 in Scandinavia (3 centers), 129 in the US (3 centers), and 100 patients in South Korea (2 centers). Regional variation in patient demographics was assessed using Kruskal-Wallis H tests. Regional variation in PROM scores from preoperative, 1-, 3- and 5-year visits was assessed using piecewise linear mixed effect models. The PROMs analyzed were a numerical rating scale for satisfaction and the Knee Osteoarthritis Outcome Score. RESULTS South Korean patients were the oldest (p < 0.001) and had the highest Charnley class (p < 0.001); US patients had the highest BMI (p < 0.001); Scandinavian patients had the lowest preoperative KL grade (p < 0.001). Scandinavian patients were associated with better preoperative and worse postoperative PROM scores. Scandinavian patients were also associated with moderately lower levels of satisfaction. These differences were lessened but remained significant after controlling for relevant demographic and surgical factors. CONCLUSIONS Regional differences were found in TKA patient demographics and PROMs between the US, Scandinavia, and South Korea. The regional differences in patient demographics support the need for more research and clear guidelines related to TKA appropriateness criteria. The better preoperative and worse postoperative Scandinavian PROM scores may have been related to their less severe KL grade but might also reflect cultural differences in how patients reflect on their health state when answering PROMs. Clinicians should be aware of these international differences in PROM scores when interpreting studies conducted in different international regions. Future studies should investigate TKA variation between more international regions and assess intraregional variation. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND Knee osteoarthritis is one of the most common orthopedic diseases. However, few studies have reported the morphometric characteristics of the lower leg related to the progression of knee osteoarthritis in regional populations. This study aimed to determine the radiographic morphometries of the lower leg in subjects who showed progression of osteoarthritis of the knee in the TOEI cohort. METHODS Data were collected from the TOEI study cohort, during the period from 2014 to 2016, to assess osteoarthritis of the knee and radiographic morphometries of the lower leg. The joints were divided into three groups according to osteoarthritis progression over 2 years. There were 323 legs of females and 163 legs of males. Knees which did not exhibit osteoarthritis were in group 1; knees with osteoarthritis that remained stable for 2 years were in group 2; knees that worsened osteoarthritis over 2 years were in group 3. Morphometric parameters in the lower leg were measured by radiographs taken in 2014. RESULTS In female subjects, group 2 had higher age, lower lever arm ratio and lower hip-knee-ankle angle, and higher height of the hip center compared with group (1). Group 3 had higher age compared with group 1 and lower height of the hip center compared with group (2). In male subjects, group 2 had lower height of the hip center and lower hip-knee-ankle angle compared with group 1. Group 3 had higher patellar shift index compared with group 1, higher height of the hip center and higher femoral neck length compared with group 2. CONCLUSIONS Higher age was the risk of osteoarthritis progression of the knee in female subjects but not significant risk in male subjects. Hip morphometries such as height of the hip center and femoral neck length in which showed a sex difference might be associated with the progression of knee osteoarthritis.

Abstract
OBJECTIVE To evaluate racial and ethnic disparities in utilization of total knee arthroplasty (TKA) in relation to demographic, health, and socioeconomic status variables. DESIGN Prospective study of 102,767 Women's Health Initiative postmenopausal women initially aged 50-79, examining utilization rates of primary TKA between non-Hispanic Black/African American, non-Hispanic White, and Hispanic/Latina women (hereafter referred to as Black, White, and Hispanic). A total of 8,942 Black, 3,405 Hispanic, and 90,420 White women with linked Medicare claims data were followed until time of TKA, death, or transition from fee-for-service coverage. Absolute disparities were determined using utilization rates by racial/ethnic group and relative disparities quantified using multivariable hazards models in adjusting for age, arthritis, joint pain, mobility disability, body mass index, number of comorbidities, income, education, neighborhood socioeconomic status (SES), and geographic region. RESULTS TKA utilization was higher among White women (10.7/1,000 person-years) compared to Black (8.5/1,000 person-years) and Hispanic women (7.6/1,000 person-years). Among women with health indicators for TKA including diagnosis of arthritis, moderate to severe joint pain, and mobility disability, Black and Hispanic women were significantly less likely to undergo TKA after adjusting for age [Black: HR (95% confidence interval) = 0.70 (0.63-0.79); Hispanic: HR = 0.58 (0.44-0.77)]. Adjustment for SES modestly attenuated the measured disparity, but significant differences remained [Black: HR = 0.75 (0.67-0.89); Hispanic: HR = 0.65 (0.47-0.89)]. CONCLUSIONS Compared to White women, Black and Hispanic women were significantly less likely to undergo TKA after considering need and appropriateness for TKA and SES. Further investigation into personal-level and provider-level factors that may explain these disparities is warranted.

Abstract
Background and Objectives Osteoarthritis (OA) is the most prevalent worldwide joint degenerative disorder with high morbidities and disabilities. The current study aimed to investigate the prevalence of knee osteoarthritis (KOA) in Arar by using magnetic resonance imaging (MRI). Methods The prevalence of KOA was studied in Arar through MRI evaluation of randomly chosen sample from patients and their relatives attending the Prince Abdul Aziz Bin Mussad Hospital from October 2015 to November 2016. Results A total of 410 participants were enrolled in the study [328 (80%) male and 82 (20%) females]. After MRI, 163 participants [39.75% (95% CI) = 35.14 - 44.57%)] were diagnosed with KOA. The prevalence of OA was about 25.6% (95% CI = 20.8 - 31.1%) below the age of 40 years, which was found to increase by age in the enrolled volunteers. KOA prevalence was higher in females than males (75.6% and 27.7% respectively). There was a significant association between the age and genders of the participants and the prevalence of OA (p-value < 0.0001 for both variables). There was also a significant association between the age and gender of the participants and the MRI-estimated grading (p-value < 0.0001 and 0.0044 respectively). Conclusion KOA is a common disease among Arar young population, especially females. Its prevalence increases by age with higher grades of severity affecting the elderly.

Abstract
This study compared the dosage and different medication-taking habits of glucosamine sulfate (GS) for osteoarthritis patients and evaluated the influence of the National Health Insurance (NHI) prescription guidelines. The subjects were collected from the Taiwan NHI Research Database from 1 January 2004, to 31 December 2008, and 10,501 osteoarthritis patients were included. Then, 271 patients who continuously used nonsteroidal anti-inflammatory drug (NSAIDs) and started to receive glucosamine for the first time since 2005 (no glucosamine use in 2004) were compared with 593 age-matched patients who continuously used NSAIDs but never received any glucosamine drugs from 2004 to 2008. The mean treatment duration of the glucosamine-treated and NSAID-treated groups was 40.38 ± 7.89 and 45.82 ± 3.89 months, respectively. The most common medication-taking habit was 250 mg 3 times a day for 3 months and discontinued for 3 months. It was as indicated and covered by the NHI. Only 0.7% of patients used the recommended daily dosage of 1500 mg. Patients using GS surprisingly had a higher incidence rate of joint replacement surgery than those who did not use GS. The NHI prescription guidelines may cause patient selection bias, which decreases the efficacy of GS. Moreover, patients tend to have an altered medication-taking habit, with a daily dosage of 750 mg, which is lower than the recommended therapeutic dose.

Abstract
The purpose of this study was to validate the Knee Injury and Osteoarthritis Outcome Score (KOOS) for elderly patients who undergo total knee replacement (TKR). The validated Spanish versions of the KOOS and Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) questionnaires were applied to 137 patients (mean age 72.3, SD 7.5 years). Test-retest data were collected with an intermediate period of 1-2 weeks. To evaluate the clinimetric properties of the KOOS, internal consistency (Cronbach's α), reproducibility (intraclass correlation coefficient [ICC]), construct validity (Spearman's correlation), responsiveness (effect sizes [ES], and standardized response mean [SRM]), and floor and ceiling effects (<15%) were assessed. As result, Cronbach's coefficients of the KOOS subscales ranged from 0.78 to 0.93, and ICC from 0.76 to 0.91. Construct validity was supported by the confirmation of the three predefined hypotheses involving expected correlations between KOOS subscale and SF-36 physical health subscales. Spearman's correlations were strong between KOOS Pain and SF-36 Bodily Pain (r = 0.81), KOOS Pain and SF-36 Physical Functioning (r = 0.67), KOOS activities of daily living (ADL) and SF-36 Bodily Pain (r = 0.69), KOOS ADL and SF-36 Physical Functioning (r = 0.74), and KOOS Sports/Recreation and SF-36 Physical Functioning (r = 0.76). Responsiveness at 1 year after TKR was large with the ES ranging from 0.81 to 2.12, and the SRM from 0.70 to 1.91. Floor and ceiling effects were low. In conclusion, the Spanish version of KOOS has successful psychometric characteristics and is a reliable and valid instrument for assessment of patient-relevant outcomes in elderly patients with advanced OA who undergo TKR. © 2019 Orthopaedic Research Society.

Abstract
Conventional arthroscopic evaluation of articular cartilage is subjective and insufficient for assessing early compositional and structural changes during the progression of post-traumatic osteoarthritis. Therefore, in this study, arthroscopic near-infrared (NIR) spectroscopy is introduced, for the first time, for in vivo evaluation of articular cartilage thickness, proteoglycan (PG) content, and collagen orientation angle. NIR spectra were acquired in vivo and in vitro from equine cartilage adjacent to experimental cartilage repair sites. As reference, digital densitometry and polarized light microscopy were used to evaluate superficial and full-thickness PG content and collagen orientation angle. To relate NIR spectra and cartilage properties, ensemble neural networks, each with two different architectures, were trained and evaluated by using Spearman’s correlation analysis (ρ). The ensemble networks enabled accurate predictions for full-thickness reference properties (PG content: ρin vitro, Val= 0.691, ρin vivo= 0.676; collagen orientation angle: ρin vitro, Val= 0.626, ρin vivo= 0.574) from NIR spectral data. In addition, the networks enabled reliable prediction of PG content in superficial (25%) cartilage (ρin vitro, Val= 0.650, ρin vivo= 0.613) and cartilage thickness (ρin vitro, Val= 0.797, ρin vivo= 0.596). To conclude, NIR spectroscopy could enhance the detection of initial cartilage degeneration and thus enable demarcation of the boundary between healthy and compromised cartilage tissue during arthroscopic surgery.

Abstract
OBJECTIVE To investigate the longitudinal association between objectively measured ambulatory activity (AA) and knee MRI-detected osteophytes (OPs), and to test whether this relationship was modified by common risk factors for OA including sex, obesity, disease severity and knee injury history. METHODS 408 community-dwelling adults aged 51-81 years were assessed at baseline and 2.7 years. T1-weighted fat-suppressed MRI was used to evaluate knee OPs at both time points. AA was assessed at baseline by pedometers and categorized as: less active (≤7499 steps per day), moderately active (7500-9999 steps per day) and highly active (≥10,000 steps per day). RESULTS Statistically significant interactions were detected between knee OA risk factors and AA on increases in MRI-detected OPs (all P < 0.05). In stratified analyses, being moderately active, compared to being less active, was protective against an increase in MRI-detected OPs (score change of ≥1) in females (relative risk (RR) = 0.42, 95%CI, 0.25-0.70, P < 0.01), those who were obese (RR = 0.50, 95%CI, 0.30-0.83, P < 0.01), those with radiographic OA (ROA) (RR = 0.68, 95%CI, 0.47-0.97, P = 0.02) and those with a history of knee injury (RR = 0.27, 95%CI, 0.08-0.88, P = 0.02) in almost every knee compartment, after adjustment for confounders. No statistically significant associations were found in males, non-obese, non-ROA or non-injury groups. CONCLUSIONS Being moderately active is protective against an increase in MRI-detected OPs in females, those with ROA, those who are obese and those with a history of knee injury. These findings suggest that being moderately active is beneficial for individuals who are at higher risk of knee OA.

Abstract
Soy lecithin has been shown to play a critical role in cell signaling and cellular membrane structure. In addition, it has been shown to increase biocompatibility, hydrophilicity, and decrease cytotoxicity. Gold nanoparticles have also shown to improve cellularity. Lecithin, gold nanoparticles, and polycaprolactone (PCL) solutions were electrospun in order to develop unique mesh materials for the treatment of osteoarthritis. The electrospinning parameters were optimized to achieve different solution ratios for fiber optimization. The amount of lecithin mixed with PCL varied from 30 wt.% to 50 wt.% . Gold nanoparticles (1% to 10% concentrations) were also added to lecithin-PCL mixture. The mechanical and chemical properties of the fiber mesh were analyzed via contact angle test, tensile mechanical tests, Fourier transform infrared spectroscopy (FTIR), and differential scanning calorimetry (DSC). Cell viability was measured using a WST-1 Assay. Scanning electron microscopy confirmed the successful formation of fiber mesh. The compositions of 40% soy lecithin with PCL in 40% solvent (40:40) resulted in the most well-formed fiber mesh. DSC melt temperatures were statically insignificant; uniaxial stresses and the moduli resulted in no significant difference between the test composition and pristine PCL compositions. WST-1 assay revealed all compositions were non-cytotoxic. Overall, the addition of lecithin increased hydrophilicity while maintaining cell viability and the mechanical and chemical properties of PCL. This study demonstrated that it is possible to successfully electrospin a lecithin, gold nanoparticle, and polycaprolactone scaffold for tissue engineering applications.

The Potential of Menstrual Blood-Derived Mesenchymal Stem Cells for Cartilage Repair and Regeneration: Novel Aspects. Stem Cells Int 2018; 2018:5748126.

Abstract
Menstrual blood is a unique body fluid that contains mesenchymal stem cells (MSCs). These cells have attracted a great deal of attention due to their exceptional advantages including easy access and frequently accessible sample source and no need for complex ethical and surgical interventions, as compared to other tissues. Menstrual blood-derived MSCs possess all the major stem cell properties and even have a greater proliferation and differentiation potential as compared to bone marrow-derived MSCs, making them a perspective tool in a further clinical practice. Although the potential of menstrual blood stem cells to differentiate into a large variety of tissue cells has been studied in many studies, their chondrogenic properties have not been extensively explored and investigated. Articular cartilage is susceptible to traumas and degenerative diseases, such as osteoarthritis, and has poor self-regeneration capacity and therefore requires more effective therapeutic technique. MSCs seem promising candidates for cartilage regeneration; however, no clinically effective stem cell-based repair method has yet emerged. This chapter focuses on studies in the field of menstrual blood-derived MSCs and their chondrogenic differentiation potential and suitability for application in cartilage regeneration. Although a very limited number of studies have been made in this field thus far, these cells might emerge as an efficient and easily accessible source of multipotent cells for cartilage engineering and cell-based chondroprotective therapy.

Abstract
Recent years have witnessed an increased prevalence of knee osteoarthritis (KOA) among diabetes mellitus (DM) patients-conditions which might share common risk factors such as obesity and advanced aging. Therefore, we conducted dry-to-wet lab research approaches to assess the correlation of type 1 DM (T1DM) and type 2 DM (T2DM) with KOA among all age and genders of Taiwanese population. The strength of association (odds ratio: OR) was analyzed using a phenome-wide association study portal. Populations of 37,353 T1DM and 1,218,254 T2DM were included. We observed a significant association of KOA with T1DM (OR: 1.40 (1.33⁻1.47), p< 0.0001) and T2DM (OR: 2.75 (2.72⁻2.78), p< 0.0001). The association between T1DM and KOA among the obese (OR: 0.99 (0.54⁻1.67), p = 0.0477) was insignificant compared to the non-obese (OR: 1.40 (1.33⁻1.48), p < 0.0001). Interestingly, a higher association between T2DM and KOA among non-obese persons (OR: 2.75, (2.72⁻2.79), p < 0.0001) compared to the obese (OR: 1.71 (1.55⁻1.89), p < 0.0001) was noted. Further, histopathologic and Western blot studies of diabetic mice knee joints revealed enhanced carboxymethyl lysine (advanced glycation end product), matrix metalloproteinase-1, and reduced cartilage-specific proteins, including type II collagen (Col II), SOX9, and aggrecan (AGN), indicating deteriorated articular cartilage and proteoglycans. Results indicate that DM is strongly associated with KOA, and obesity may not be a confounding factor.

Abstract
INTRODUCTION Prevalence of knee osteoarthritis (KOA) has not been assessed in Sri Lanka, since 2006. This study aimed to determine the prevalence of clinical KOA and radiographic KOA and to assess the severity of it, among adult females of a suburban setting in Sri Lanka. METHODS A cross-sectional survey was conducted among a representative sample of 666 females aged 50 years or more resident in Pita Kotte Medical Officer of Health area. Four physiotherapy graduates applied American College of Rheumatology (ACR) criteria by performing the clinical assessment in the households. Participants with clinical knee osteoarthritis were referred for radiography to identify radiographic osteoarthritis and to assess severity. Age standardized prevalence of clinical KOA for Sri Lanka was estimated based on population statistics of 2001 Census. RESULTS Study included 666 adult females with a response rate of 99.4%. The mean age was 63.3 years (±9.29 years). A total of 134 were found to satisfy ACR criteria resulting in a crude prevalence of clinical KOA of 20.1% (95% CI 17.0%-23.2%). Estimated age standardized prevalence of clinical KOA for Sri Lanka was 21.8% (95% CI 21.7-21.9). Among those with clinical KOA 58.9% showed radiographic KOA and the prevalence of moderate/severe KOA among those with clinical KOA was 29.9%. CONCLUSION AND RECOMMENDATIONS Prevalence of clinical KOA among the adult females over 50 years was high with considerable proportion of them being moderate /severe KOA. These findings should be used to advice the health authorities regarding improving preventive and curative services for KOA.

Abstract
Background The number of patients receiving total knee arthroplasty (TKA) has been rising every year due to the aging population and the obesity epidemic. Post-operative rehabilitation is important for the outcome of TKA. Methods A series of 34 patients who underwent primary unilateral TKA was retrospectively collected and divided into either exercise group (n = 16) and control group (n = 18). The exercise group underwent a 24-week course of circuit training beginning 3 months after total knee arthroplasty (TKA). The effect of circuit training on TKA patients in terms of motion analysis, muscle strength testing, Knee injury and Osteoarthritis Outcomes Score (KOOS) questionnaire and patient-reported outcome measurement Short-Form Health Survey (SF-36) at the pre-operation, pre-exercise, mid-exercise, and post-exercise. Results Motion analysis revealed the stride length, step velocity, and excursion of active knee range of motion significantly improved in the exercise group when compared to those in the control group. KOOS questionnaire showed a greater improvement in pain, ADL, and total scores in the exercise group. The SF-36 questionnaire revealed a significant improvement in general health, bodily pain, social function, and physical components score in the exercise group. Conclusions The post-operative circuit training intervention can facilitate recovery of knee function and decrease the degree of pain in the TKA and might be considered a useful adjunct rehabilitative modality. The ultimate influence of circuit training on TKA needs further a prospective randomized clinical trial study and long-term investigation. Trial registration NCT02928562

Abstract
CONTEXT Total knee arthroplasty (TKA) is associated with severe postoperative pain which increases morbidity and mortality. AIMS The aim of the study was to compare the analgesic efficacy and motor blockade of continuous infusion of 0.125% bupivacaine and 0.2% ropivacaine in femoral nerve block following unilateral TKA and to assess the effectiveness of femoral nerve block. SETTINGS AND DESIGN One hundred and fifty patients undergoing unilateral total knee replacement surgery were included in this prospective observational comparative study. SUBJECTS AND METHODS Patients are divided into two groups of 75 each. Femoral nerve catheter was placed at the end of surgery using ultrasound. Postoperative analgesia and motor blockade were compared for the next 24 h using visual analog scale (VAS) score, additional analgesic requirement, and Bromage scale. STATISTICAL ANALYSIS Student's t-test and Chi-square test were applied. RESULTS There was no statistically significant difference in pain between the two groups though VAS score (during rest and movement) and opioid consumption were lower in bupivacaine group. Nearly 28.6% patients experienced pain and required additional analgesics. Seventy-two percent among them complained of pain in the popliteal region supplied by sciatic nerve. Eight patients excluded from the study also had pain in the popliteal fossa. There was a statistically significant difference in motor blockade between the two groups at 12, 18, and 24 h after starting infusion. Bupivacaine group had a higher percentage of type three blocks compared to ropivacaine group. CONCLUSION Continuous femoral nerve block (CFNB) with 0.125% bupivacaine infusion provided better analgesia with denser motor blockade compared to 0.2% ropivacaine infusion. CFNB alone is not sufficient to provide adequate analgesia following unilateral TKA.

Abstract
BACKGROUND Impact of gender on 30-day complications has been investigated in other surgical procedures but has not yet been studied in total hip arthroplasty (THA) or total knee arthroplasty (TKA). METHODS Patients who received THA or TKA from 2012 to 2014 were identified in the National Surgical Quality Improvement Program database. Patients were divided into 2 groups based on gender. Bivariate and multivariate analyses were performed to assess associations between gender and patient factors and complications after THA or TKA and to assess whether gender was an independent risk factor. RESULTS THA patients consisted of 45.1% male and 54.9% female. In a multivariate analysis, female gender was found to be a protective factor for mortality, sepsis, cardiovascular complications, unplanned reintubation, and renal complications and as an independent risk factor for urinary tract infection, blood transfusion, and nonhome discharge after THA. TKA patients consisted of 36.7% male and 62.3% female. Multivariate analysis revealed female gender as a protective factor for sepsis, cardiovascular complications, and renal complications and as an independent risk factor for urinary tract infection, blood transfusion, and nonhome discharge after TKA. CONCLUSION There are discrepancies in the THA or TKA complications based on gender, and the multivariate analyses confirmed gender as an independent risk factor for certain complications. Physicians should be mindful of patient's gender for better risk stratification and informed consent.

Abstract
OBJECTIVES To examine the incidence and predictors of blood transfusion following total knee replacement (TKR). Methods: A retrospective study on 462 patients of primary TKR at National Guard Hospital, Riyadh, Kingdom of Saudi Arabia. Descriptive statistics were compared by blood transfusion status and significant variables were further included in the multivariable model. Results: Overall transfusion rate following TKR was 35.3%. Regression analyses identified bilateral surgery, low preoperative hemoglobin (Hb) level, and high amount of blood loss as predictors of blood transfusion. Conclusion: Correction of Hb level prior to surgery, careful hemostasis, and avoiding bilateral surgery may reduce the rate of blood transfusion following TKR.

Abstract
This research investigates the prevalence of human osteoarthritis at Yinxu, the last capital of the Late Shang dynasty (ca. 1250–1046 B.C.), to gain insights about lifeways of early urban populations in ancient China. A total of 167 skeletal remains from two sites (Xiaomintun and Xin’anzhuang) were analyzed to examine osteoarthritis at eight appendicular joints and through three spinal osseous indicators. High osteoarthritis frequencies were found in the remains with males showing significantly higher osteoarthritis on the upper body (compared to that of the females). This distinctive pattern becomes more obvious for males from Xiaomintun. Furthermore, Xiaomintun people showed significantly higher osteoarthritis in both sexes than those from Xin’anzhuang. Higher upper body osteoarthritis is speculated to be caused by repetitive lifting and carrying heavy-weight objects, disproportionately adding more stress and thus more osseous changes to the upper than the lower body. Such lifting-carrying could be derived from intensified physical activities in general and specialized occupations in particular. Higher osteoarthritis in males may reveal a gendered division of labour, with higher osteoarthritis in Xiaomintun strongly indicating an occupational difference between the two sites. The latter speculation can be supported by the recovery of substantially more bronze-casting artifacts in Xiaomintun. It is also intriguing that relatively higher osteoarthritis was noticed in Xiaomintun females, which seems to suggest that those women might have also participated in bronze-casting activities as a “family business.” Such a family-involved occupation, if it existed, may have contributed to establishment of occupation-oriented neighborhoods as proposed by many Shang archaeologists.

Abstract
Background: Despite the advances in the design and fixation of implants in total knee replacement (TKR). the amount of postoperative bleeding is still an important issue that has not been resolved. This study aimed to measure the effectiveness of various tranexamic acid administration.
Methods: This was a randomized controlled trial study, held from August 2014 to February 2016 at Cipto Mangunkusumo Hospital, Jakarta. Twenty two patients having TKR were divided into three groups: the control group, the tranexamic acid intra-articular-intraoperative group, and the intravenous preoperative group. Intraoperative bleeding, haemoglobin (Hb) level on preoperative to five-day-post-surgery, total drain production, total blood tranfusion needed and the drain removal timing were recorded and compared. Numerical data were analyzed by using parametric and non-parametric test, depended on the normality of the data.
Results: The amount of blood transfusion needed in both the intra-articular group (200±SD 100 mL) and the intravenous group (238±SD 53 mL) were significantly different compared to those in the control group (1,016±SD 308.2 mL) (p=0.001). Meanwhile, there was no significant difference between the amount of blood transfusion needed in the intra-articular group and the intravenous group. Total drain production in the intra-articular group (328±SD 193 mL) and intravenous group (391±SD 185 mL) was significantly different compared to the control group (652±SD 150 mL) (p=0.003). No significant difference between the levels of both preoperative and postoperative haemoglobin, the amount of intraoperative bleeding, and the duration of drain usage.
Conclusion: Intravenous and intra-articular tranexamic acid effectively decreased transfusion volume and drain production in patients undergoing TKR.

Oncotarget 2017; 8:4228-4233. [PMID: 27980229 PMCID: PMC5354826 DOI: 10.18632/oncotarget.13935] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2016] [Accepted: 12/07/2016] [Indexed: 11/25/2022] Open
Abstract
IL1R1, encoding interleukin 1 receptor type 1, is located in the IL-1 gene cluster and is involved in the pathogenesis of hand, hip, and knee osteoarthritis (OA) in different ethnicities. However, the link between IL1R1 polymorphisms and OA risk in the Chinese Han population is unknown. We studied the association between five IL1R1 polymorphisms (rs10490571, rs12712127, rs956730, rs3917225, and rs3917318) and OA risk by analyzing the genotypes of 298 knee OA patients and 297 controls using Sequenom MassARRAY technology. Logistic regression analysis after adjusting for gender and age revealed significant differences in the allele frequencies of IL1R1 rs956730 and IL1R1 rs3917225 between patients and controls. In addition, IL1R1 rs3917225 was associated with increased risk of knee OA with or without adjustment by age and gender in the dominant model (adjusted OR= 1.47, 95%CI: 1.04-2.07, P = 0.030), the recessive model (adjusted OR= 1.75, 95%CI: 1.08-2.85, P= 0.023), and the additive model (adjusted OR= 1.40, 95%CI: 1.09-1.79, P = 0.007). This study is the first to report that IL1R1 polymorphisms are associated with knee OA susceptibility in the Northwestern Chinese Han population.
