OBJECTIVE: Obesity is associated with an increased risk of developing Osteoarthritis (OA), which is postulated to be secondary to inflammation from adipose tissue (AT). There are peri-articular adipose depots in synovial joints, the association of this tissue with OA has not been extensively explored. The aim of this study was to investigate differences in local AT depots in knees with OA and changes related to class II and III obesity. METHODS: Synovium and the infrapatellar fat pad (IPFP) were collected during total knee replacement from 69 patients with end-stage OA...

High-fat diet-induced obesity is a major risk factor for osteoarthritis (OA) and diminished wound healing. The objective of this study was to determine the associations among serum and synovial fluid lipid levels with OA, synovitis, adipokine levels, and wound healing in a pre-clinical obese mouse model of OA. Male C57BL/6 J mice were fed either a low-fat (10% kcal) or one of three high-fat (HF, 60% kcal) diets rich in saturated fatty acids (SFAs), ω-6 or ω-3 polyunsaturated FAs (PUFAs). OA was induced by destabilization of the medial meniscus...

BACKGROUND: Obesity as a cause of lower extremity deformity in children has been well established. This deformity is most often seen as tibia vara, however, at our institution we have observed more obese children and adolescents over age 7 years with excessive or progressive idiopathic genu valgum. Our hypothesis is that children with idiopathic genu valgum have high rates of obesity which impact the severity of their disease. METHODS: Retrospective review of existing data was performed on 66 consecutive children/112 limbs over age 7 years with idiopathic genu valgum, seen from 2010 to 2013...

Obesity has been associated with osteoarthritis (OA) due to increased mass and metabolic factors which are independent of the biomechanical contribution to joint load. Resveratrol, a natural polyphenolic compound, exerts protective effects on OA through its anti-inflammatory property. However, the mechanism of resveratrol on obesity-related OA is unclear. To investigate the effect and possible mechanism of oral resveratrol on obesity-related OA, we fed C57BL/6J mice with a high-fat diet (HFD) for 16 weeks to establish obesity-related OA model; then two doses (22...

For many physicians, the concept of surgery as the best treatment for a medical disease such as diabetes, cardiovascular problems, hyperlipidemia, sleep apnea, hepatosteatosis, GERD, osteoarthritis, psoriasis, rheumatoid arthritis, or infertility, still sounds wrong and just a ploy by surgeons to increase their business. Since 2011, however, several non-surgical societies have recommended Weight Loss Surgery - The International Diabetes Federation, The American Diabetes Association, American Heart Association, and Obesity Society in 2015 for patients with body mass index (BMI) greater than 35 and diabetes, and to decrease cardiovascular risk factors...

OBJECTIVE: In people with hip osteoarthritis (OA), the impact of obesity on health-related quality of life (HRQoL) remains unknown. Also whether cardiovascular conditions can modify the obesity-HRQoL relation has not been explored. We aimed to 1) study the cross-sectional relationship between body mass index (BMI) and HRQoL in symptomatic hip OA patients and determine whether cardiovascular comorbidity modifies this relationship and 2) examine the impact of BMI on the course of HRQoL over time...

BACKGROUND: Recently, we determined that in a rigorously monitored environment an intensive diet-induced weight loss of 10% combined with exercise was significantly more effective at reducing pain in men and women with symptomatic knee osteoarthritis (OA) than either intervention alone. Compared to previous long-term weight loss and exercise trials of knee OA, our intensive diet-induced weight loss and exercise intervention was twice as effective at reducing pain intensity. Whether these results can be generalized to less intensively monitored cohorts is unknown...

BACKGROUND: Knee valgus and varus morbidity is at the second top place in children lower limb deformity diseases. It may cause abnormal stress distribution. The magnitude and location of contact forces on tibia plateau during gait cycle have been indicated as markers for risk of osteoarthritis. So far, few studies reported the contact stress and force distribution on tibial plateau of valgus knee of children. METHODS: To estimate the contact stresses and forces on tibial plateau of an 8-year old obese boy with valgus knee and a 7-year old healthy boy, three-dimensional (3D) finite element (FE) models of their left knee joints were developed...

Osteoarthritis (OA) is the most common degenerative joint disease and a major cause of pain and disability in adult individuals. The etiology of OA includes joint injury, obesity, aging, and heredity. However, the detailed molecular mechanisms of OA initiation and progression remain poorly understood and, currently, there are no interventions available to restore degraded cartilage or decelerate disease progression. The diathrodial joint is a complicated organ and its function is to bear weight, perform physical activity and exhibit a joint-specific range of motion during movement...

Synopsis Although osteoarthritis (OA) has traditionally been considered a disease of older age, hip and knee OA can and does affect younger adults, with a profound impact on psychosocial well-being and work capacity. Obesity and a history of traumatic knee injury (eg, anterior cruciate ligament rupture and/or meniscal tear) are key risk factors for the accelerated development of knee OA, while structural hip deformities (including those contributing to femoroacetabular impingement syndrome) are strong predictors of early-onset hip OA...

Viscosupplementation (VS) is still controversial. One of the key points is the lack of well-identified factors of response. We aimed to identify clinical and radiological factors associated with lack of relevant response after intra-articular (IA) hyaluronic acid (HA) injections in symptomatic knee osteoarthritis patients. A post hoc analysis of the HAV-2012 trial, a controlled, multicentre, double-blind, randomized, non-inferiority trial comparing 3 weekly IA injections of HA (HAnox-M or BioHA) for symptomatic tibiofemoral OA was performed...

Osteoarthritis (OA) is one of the major health problems that's development and progression is obesity-related. We believe that higher levels of insulin may explains this link especially. High levels of insulin in obesity and metabolic syndrome can induce numerous complications. Insulin can increase proliferation of chondrocyte but simultaneously, it prevents their differentiation. Moreover, hyperinsulinemia reduces the circulating level of serum T4 and conversion of T4 to T3, mimicking hypothyroidism, because thyroid hormones are necessary for the maturation of chondrocytes...
