Active clinical trials for "Osteoarthritis, Knee"

Resistance training of knee extensor muscles is being used in physiotherapy management in knee osteoarthritis (OA) to improve pain and physical function. Blood flow restriction (BFR) has been suggested to improve pain and increase muscle strength in healthy subjects and certain diseases. Although there are clinical studies suggesting improvements in knee osteoarthritis symptoms after 4-12 weeks of exercise with BFR, the acute effects of the intervention have not been known. This study aims to assess the effectiveness of low load exercise therapy combined with BFR on acute pain reduction and within 24 hours post-intervention on people with knee OA compared to a placebo group. This study will take place in Athens, Greece, as part of the postgraduate MSc program of the Physiotherapy department of the University of West Attica.

The aim of our study is to determine the effects of intra-articular Platelet Rich Plasma (PRP) prepared with two different techniques on pain intensity, functional status, quality of life, functional balance and femoral cartilage thickness in patients with knee osteoarthritis.

The main purpose of this study is to evaluate whether recruitment rates are adequate to power a future RCT. The secondary aims are to obtain preliminary information about safety and efficacy of topical diphenhydramine 5% ointment in patients with knee OA.

Knee ostheoarthritis (KOA) is a common disabling and degenerative disease leading to painful joints, articular stiffness, and decreased function. The mechanism of the ozone of relieving the pain and improving the knee function is through inhibiting the inflammation reaction in the KOA directly. Actually, the ozone intra-articular injection had been used to relieve the pain caused by KOA. The aim of this study is to evaluate the effect of intra-articular injection of medical ozone given into the knee of the osteoarthritis patients, and to compare it with intra-articular steroid injection and to investigate the effectiveness of ozone and steroid the job to determine the superiority of the injections to each other.

objective - safety and efficacy evalaution of MASTER cells injected into knee of patients with osteoarthritis background osteoarthritis Osteoarthritis is severe and intractable musculoskeletal disease that eventually leads to joint failure and pain due to inflammation and joint injury. OA is one of the most prevalent diseases. The prevalence increases with age, but overuse and trauma can result in OA in young population as well. Injured cartilage can not be regenerated spontaneously, untreated injured cartilage eventually leads to osteoarthritis. Surgical treatment may repair the damage but the reparied cartilage may turn out to be fibrocartilage rather than hyaline cartilage. Curent treatment medical therapy: medication for symptom relief, together with exercise. Medications include NSAIDS visco-supplement. surgical therapy: total knee replacement arthroplasty to overcome such limitations, cell therapy such as stem cell/ chondrocyte injection is being investigated Hypothesis - Intra articular injection of MASTER cells will show safety and efficacy in terms of pain and functional improvement. Protocol 1) deisgn : Injection of MASTER cell 1X 10^8 cells/2cc (experimental arm) or 2cc saline (placebo arm) into knee of patients with osteoarthritis 2) outcomes primary outcome : safety evaluation(adverse event) secondary outcomes : check on 1,2,3,6,9,12 months, atient reported outcome (WOMAC, KOOS, IKDC, pain VAS) 3,12 months SF-36, knee MRI score, serum cytokine, bone turnover marker 12 months x-ray 3) Disease osteoarthritis 4) Subjects inclusion : age 20-80yrs, diagnosed with OA according to ACR criteria for knee OA, baseline pain VAS equal or more than 50mm exclusion: lower extremities surgery within 6months or planned surgery, concommitant systemic rheumatic diseases that can affect the results of the trial, steroid intraarticular inejction into the index knee within 3months, clinicallly meaningful abnormal lab tests (liver function, kidney function) 5) evaluation primary outome : compare the number and proportion of of adverse event and lab test abnormalities between the two arms secondary outome change of 100mm pain VAS change of Western Ontario and McMAster Universities Osteoarthritis (WOMAC) pain VAS, IKDC, KOOS total score change WOMAC sub scale, IKDC, KOOS chagne of KHAQ change of MRI indices change of x-ray( joins space narrowing) change of serum ESR/CRP, CTX-II

To study the efficacy of laser acupuncture on osteoarthritis (OA) knee patients by magnetic resonance imaging (MRI), clinical evaluation and movement analysis.

Osteoarthritis of the knee joint causes pain, stiffness, and restriction of joint movement in the knee joint due to degeneration of the knee cartilage. The purpose of osteoarthritis treatment is to improve the joint pain and prevent further damage to the joint. Selective Cox-2 inhibitors are the most commonly used nonsteroid anti-inflammatory drugs(NSAIDs) for the treatment of osteoarthritis of the knee joint. However, the safety of selective Cox-2 inhibitors is still controversial. Although these NSAIDs are effective in reducing pain and inflammation, they cannot be called a fundamental treatment for knee arthritis. Accordingly, interest in SYSADOA (Symptomatic Slow-acting Drugs for Osteoarthritis) is gradually increasing. Joins is a herbal anti-arthritic drug that has various physiological activities and a new concept of osteoarthritis treatment. It has anti-inflammatory, analgesic and joint cartilage protection effects as well as fundamental treatment. Joins is used to improve articular cartilage metabolism, can delay the progression of degenerative arthritis in the knee and compensate for the disadvantages of Selective Cox-2 inhibitors. However, when the selective Cox-2 inhibitor and Joins tablet are used alone, the therapeutic effect on knee degenerative arthritis may be limited. The purpose of this study is to investigate the therapeutic effect and safety of joining together with celecoxib for degenerative arthritis of the knee joint, and to determine the degree of analgesic and anti-inflammatory effects of the combination therapy.

The high prevalence of knee osteoarthritis and the absence of well-defined protocols for the application of Magnetotherapy (MT), makes it necessary to investigate the effect of this therapy on patients with knee osteoarthritis. Furthermore, no studies are comparing the effectiveness of the two interventions proposed in this project (MT) and microwaves (MW), which are routinely applied in clinical practice, without solid scientific evidence to justify their use. The purpose of the present clinical trial is to compare MT with MW both combined with a therapeutic exercise program in patients with painful knee osteoarthritis and its influence on pain and function.

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.
