Active clinical trials for "Osteoarthritis"

Chronic pain affects more than 50 million adults in the United States and is estimated to cost the nation more than $560 billion dollars each year. Regular physical activity is widely recognized as essential for maintaining health for all individuals, but is particularly important for individuals with chronic pain (ICPs) as physical activity can prevent further deconditioning and may even improve pain outcomes. Previous literature has shown that certain categories of partner behaviors (e.g., solicitous, punishing, distracting) are associated with different health outcomes for ICPs, and recently researchers have begun examining partner behaviors through the lens of Self-Determination Theory, specifically looking at the effects of autonomy support from a spouse on physical activity among ICPs. Partner autonomy support has been positively associated with physical activity levels and better health outcomes, but no studies to date have explored what factors predict whether or not a partner will use an autonomy supportive interpersonal style (as opposed to a controlling interpersonal style) with the ICP. Similarly, more research is needed on the mechanisms by which autonomy support promotes positive outcomes for ICPs. Though receiving autonomy support has been linked to increased physical activity and improved mental health, no studies have yet tested the full Self-Determination Theory model as one possible explanation of the link between this form of partner support and desirable health outcomes. In particular, it is important to understand the ICP's perspective on how partner autonomy support influences need satisfaction and autonomous motivation as possible mediators between autonomy support and ICP physical activity. Furthermore, little research has explored other need supportive behaviors or their need frustrating counterparts. The current study will not only provide greater understanding of autonomy support, but will also expand the literature regarding these other need supportive and need thwarting behaviors. Lastly, given the value of need supportive behaviors from one's partner, it is essential to evaluate how partner perceptions of those need supportive behaviors align with ICP's perceptions of those behaviors. Any need support a partner provides is likely moderated by the ICP's perception of that support.

Knee osteoarthritis is a common condition characterized by pain and functional disability in older people. Prevalence increases with age and is more frequent in older women. The aim of this study was to assess the effects of an 8-weeks individualized comprehensive rehabilitation program with elastic bands on pain and functional disability in chronic knee osteoarthritis.

Geniculate Artery Embolization (GAE) has recently been described and studied as a palliative treatment for osteoarthrosis-related knee pain in patients un-eligible for surgical intervention. This treatment is based on the hypothesis that hypervascularization and associated increased nerve proliferation are possible sources of chronic pain following the morphological changes of osteoarthrosis. A large animal model has shown digital subtraction arteriography to be well correlated to both the histological findings of synovial inflammation and synovial contrast enhancement on magnetic resonance imaging. This embolization technique has also been applied to other regions of the musculoskeletal system including the elbow and the shoulder.

The investigators will be comparing the efficacy of two different techniques for performing an adductor canal block to the saphenous nerve as a part of the multimodal pain control regimen for total knee arthroplasty. The investigators will be comparing a "low adductor canal block" in which the surgeon administers local anesthetic to the distal aspect of the nerve from the operative site to a "high adductor canal block" in which the anesthesiologist administers the local anesthetic more proximally along the thigh using ultrasound guidance. The investigators will power the study for non-inferiority to compare the newer "low" block to the more commonly performed and more widely studied "high" block.

Stromal vascular fraction of cells (SVF) will be extracted from lipoaspirate by enzymatic digestion. SVF will be administered in a single dose intraarticularly. All patients will receive cell therapy.This is a single arm study with no control.

Disabling symptoms of osteoarthritis are seen in approximatively 10% of people over 55 years old. Many patients suffer from persistent pain symptoms from moderate osteoarthritis despite optimal medical treatment. For these patients, several minimally-invasive surgical treatments have been proposed, including arthroscopic lavage and debridement; however, none of these treatments have been proven effective compared to sham treatment. Recently, catheter-directed embolotherapy of the geniculate arteries has been propagated as a real alternative to medical management in patients with mild to moderate knee osteoarthritis unresponsive to conservative medical management.

Articular cartilage degradation is the main characteristic of osteoarthritis (OA), involving enzymatic and inflammatory mechanisms that change it into a chronic disease. Since articular cartilage shows limited regenerative ability, several intra-articular drugs have been developed in order to decrease inflammation and provide a better clinical outcome to the patient.

The purpose of this study is to explore the efficacy and safety of autologous adipose mesenchymal stem cells in the treatment of early knee arthritis. Investigator believes that autologous adipose mesenchymal stem cells can relieve pain, improve knee function, promote knee cartilage regeneration and improve life satisfaction of patients.

This study was aimed to evaluate the efficacy and safety of Autologous Adipose-derived Mesenchymal Stem Cell Gel combine with High tibial osteotomy therapy in the treatment of cartilage damage in the knee. Investigator believe that this method will enable patients to recover better knee function and more repair of knee cartilage.

This is a randomized controlled trial comparing the short-term effect of electromoxibustion and knee health education for relieving knee pain in older adults with knee osteoarthritis.
