BACKGROUND: Cartilage changes are an important early finding of osteoarthritis (OA), which can exist even before symptoms. Our objective was to determine the prevalence of knee cartilage damage on magnetic resonance imaging (MRI) in an asymptomatic population-based cross-sectional study and to evaluate the association of body mass index (BMI) with cartilage damage. METHODS: Subjects, aged 40-79 years, without knee pain (n = 73) were recruited as a random population sample and assessed for BMI (kg/m2), including current BMI (measured), past BMI at age 25 (self-reported) and change in BMI...

MiR-204 and 211 enforced expression in murine mesenchymal stromal cells (MSCs) has been shown to induce adipogenesis and impair osteogenesis, through RUNX2 down-modulation. This mechanism has been suggested to play a role in osteoporosis associated with obesity. However, two further fundamental MSC functions, chondrogenesis and hematopoietic supporting activity, have not yet been explored. To this end, we transduced, by a lenti-viral vector, miR-204 and 211 in a model primary human MSC line, opportunely chosen among our MSC collection for displaying all properties of canonical bone marrow MSCs, except adipogenesis...

Osteoarthritis (OA) of the knee is one of the most relevant and debilitating health problems. Obesity represents one of the major risk factor for early development of OA. In the obese population, knee replacement should be delayed and eventually avoided and prefer conservative treatments including intrarticular hyaluronic acid (HA) viscosupplementation. In the present clinical randomized trial, we present a comparison between two groups of 24 obese patients which were randomized to be treated with two intrarticular injections of hybrid (low and high molecular weight) hyaluronic acid (Group A) or two injections of high molecular weight hyaluronic acid (Group B)...

INTRODUCTION: Today, not only the existence of an interrelation between obesity/adipositas and osteoarthritis (OA) but also the association of OA and diabetes mellitus (DM) are widely recognized. Nevertheless, shared influence factors facilitating OA development in DM patients still remain speculative up until now. To supplement the analysis of clinical data, appropriate in vitro models could help to identify shared pathogenetic pathways. Informative in vitro studies could later be complemented by in vivo data obtained from suitable animal models...

A link between inflammation with obesity and metabolic syndrome has been found in patients with chronic kidney disease (CKD). Diacerein is an anthraquinone used to treat osteoarthritis that exerts anti-inflammatory action by inhibiting the synthesis and activity of proinflammatory cytokines. This study aimed to investigate the protective effect of diacerein on renal function and renal organic anion transporter 3 (Oat3) function in obese insulin-resistant condition. Obese insulin-resistant rats were induced by feeding a high-fat diet in male Wistar rats for 16 weeks...

BACKGROUND: Metabolic syndrome (MetS) may be associated with knee osteoarthritis (OA), but the association between the individual components and OA are not well-understood. We aimed to study the effect of hypercholesterolemia on synovial inflammation in knee OA. METHODS: OA was surgically induced in rabbits fed with standard diet (OA group, n = 10) or in rabbits fed with high fat diet (OA-HFD, n = 10). Healthy rabbits receiving standard diet (Control, n = 10) or fed with HFD (HFD, n = 6) were also monitored...

Pain due to osteoarthritis (OA) is one of the most frequent causes of chronic pain. However, the mechanisms of OA pain are poorly understood. This review addresses the mechanisms which are thought to be involved in OA pain, derived from studies on pain mechanisms in humans and in experimental models of OA. Three areas will be considered, namely local processes in the joint associated with OA pain, neuronal mechanisms involved in OA pain, and general factors which influence OA pain. Except the cartilage all structures of the joints are innervated by nociceptors...

Background and purpose - Osteoarthritis (OA) imposes a substantial burden on individuals and societies. We report on the burden of knee and hip OA in the Nordic region. Patients and methods - We used the findings from the 2015 Global Burden of Diseases Study to explore prevalence, years lived with disability (YLDs), and disability-adjusted life-years (DALYs) of OA in the 6 Nordic countries during 1990-2015 (population of about 27 million in 2015). Results - During 1990-2015, the number of prevalent OA cases increased by 43% to 1,507,587 (95% uncertainty interval [UI] 1,454,338-1,564,778) in the region...

Osteoarthritis (OA) is the most frequent joint disease, whereas etiopathogenesis of OA is not entirely clarified. It is a heterogeneous disorder and genetic as well as biomechanical, endocrine and inflammatory effects may be involved in its origin. The author examines the problems concerning relationships between the metabolic syndrome and OA, and states that the prevalence of metabolic syndrome in patients with OA is higher than in those without OA (59 % vs 23 %). It remains problematic that one of the main components of metabolic syndrome is obesity which in itself is a risk factor for arthrosis development in the weight-bearing joints, not for OA in the hands...

Total knee arthroplasty (TKA) is a standard treatment for patients with end stage knee Osteoarthritis (OA) to reduce pain and restore function. The aim of this study was to assess pre- and early post-operative physical activity (PA) with Fitbit Flex devices for patients with OA undergoing TKA and determine any benchmarks for expected post-operative activity. Significant correlations of pre-operative step count, post-operative step count, Body Mass Index (BMI) and Short Form 12 Physical Component Summaries (SF-12 PCS) were found...

PURPOSE OF REVIEW: Changes in the constituents and activity of the microbiome have been associated with a number of conditions linked to bone and joint disease. This review concentrates on ways in which the microbiome is known to influence osteoarthritis and osteoporosis. RECENT FINDINGS: Animal studies have demonstrated that changes in the microbiome can mediate the effects of obesity on cartilage degeneration. Additionally, the microbiome influences the amount of the bone (bone quantity), as well as bone tissue material properties (bone quality)...

The objective of the study was to investigate the effect of bariatric surgery-induced weight loss on knee gait and cartilage degeneration in osteoarthritis by combining magnetic resonance imaging, gait analysis, finite element modeling and cartilage degeneration algorithm. Gait analyses were performed for obese subjects before and one-year after the bariatric surgery. Finite element models were created before and after weight loss for those subjects who had not severe tibio-femoral knee cartilage loss. Knee cartilage degenerations were predicted using an adaptive cartilage degeneration algorithm which is based on cumulative overloading of cartilage, leading to iteratively altered cartilage properties during osteoarthritis...

Hip osteoarthritis is the most common joint disorder, and is represented by a degenerative process, resulting in pain and functional impairment. If conservative treatment for hip osteoarthritis fails, the only remaining option is hip arthroplasty. Despite good survival of implants, loosening of components is the most common complication. This leads to revision surgeries, which are technically demanding, expensive, and result in a low satisfaction rate. Uncemented hip replacements require proper osseointegration for increased survival...

Obesity is associated with an elevated risk of osteoarthritis (OA). We examined here whether high fat diet administered in young mice, compromised the attainment of articular cartilage thickness. Further, we sought to determine if low intensity vibration (LIV) could protect the retention of articular cartilage in a mouse model of diet induced obesity. Five-week-old, male, C57BL/6 mice were separated into 3 groups (n = 10): Regular diet (RD), High fat diet (HF), and HF + LIV (HFv; 90Hz, 0.2g, 30 min/d, 5 d/w) administered for 6 weeks...
