Active clinical trials for "Osteoarthritis, Knee"

Osteoarthritis (OA) is the most common joint disease associated with aging. Although many patients take glucosamine supplements as a non-traditional treatment for osteoarthritis, the effectiveness of these supplements is questionable. This study will evaluate glucosamine therapy by directly analyzing two functions of joint fluid that are impaired by osteoarthritis - namely, the abilities to lubricate the joint and absorb shocks during activity. Joint fluid samples will be collected from subjects with knee osteoarthritis and analyzed on a device that simulates typical joint movements. After 3 months of glucosamine supplementation, samples will be collected again to detect potential improvements in joint fluid function.

The purpose of this study is to identify whether corticosteroid use with anesthetics containing preservatives (parabens) reduces clinical effectiveness of the anti-inflammatory agent Up to 100 patients, both male and female, between the ages of 18-89 will be enrolled and randomized into either of the following groups; Group 1: These patients will receive a corticosteroid solution with lidocaine containing parabens. Group 2: These patients will receive corticosteroid solution with paraben free lidocaine.

The aim of this study is to discuss the effect of gait pattern in patients receiving arthroscopic cartilage regeneration facilitating procedure (ACRFP) for treatment of osteoarthritis of knees.

This study was to evaluate the safety and efficacy of Mesenchymal Stem Cells (MSCs) from umbilical cord in the treatment of 7 knee OA patients by assessing unexplained local and systemic symptoms or death before and at 1, 2, 3, 6 months after the injection.

Major Exclusion Criteria: Osteoarthritis patients with age 40-75 years; The severity of joint damage in grade one and four; Patients with history of injury and body mass index 30 or more. Intervention: Treatment with prescription of drug at dose of 15 mg daily crocin in the study group and placebo in the control group. Time: 4 months; Main outcome Measures: Osteoarthritis, Pain, Inflammation, Crocina, IL-4, IL-1 beta, IL-17, IL-10, TGF- beta, Cell surface protein CD127, The expression of T-bet, GATA-3, FOXP3, ROR-γt and the number of Th1, Th2, T-regulatory and Th17.

Postoperative wound complications such as wound dehiscence, skin necrosis, persistent wound drainage, delayed healing, and superficial skin infection could have devastating consequences, leading to arthroplasty failure and patient morbidity requiring additional operations and prolonging hospitalization with substantial burden in cost of care. Recently, interest and research on central sensitization (CS) have been increasing. CS is closely correlated with excessive pain. It has two main characteristics: allodynia and hyperalgesia. CS is an abnormal and intense enhancement of pain mechanism by the central nervous system. One of the mechanisms by which this excessive pain occurs in CS is reduced activation of descending inhibitory pathway associated with deficiency in pathways primarily in response to serotonin and norepinephrine. Serotonin plays an important role in normal wound healing by affecting the formation of neovascularization, inflammatory reactions, fibroblasts and tissue proliferation essential for wound healing. Norepinephrine is also closely related to wound healing by controlling chemotaxis of macrophage essential for normal wound healing. CS is a risk factor for the development of postoperative wound complication after primary Total Knee Arthroplasty (TKA). Preclinical models of central sensitization suggest that duloxetine is effective in the treatment. Investigators will compare the wound complication following TKA of central sensitization patients in duloxetine group (n=40) with those in non-duloxetine group (n=40). Investigators will classify the central sensitization patients by central sensitization inventory and divide the central sensitization patients in to 2 groups (duloxetine and non-duloxetine group) randomly. Investigators checks the wound complication after primary TKA and visual assessment scale at preoperative, postoperative 2 days and 1, 2,6,12 weeks. All participants will receive postoperative pain control after TKA using the same pain control regimen and wound dressing regimen except duloxetine.

The overall goal of this study is to demonstrate the safety and efficacy of Hydroxycoll bone graft substitute when used in the treatment of patients undergoing surgical treatment for varus mis-alignment in medial unicompartmental osteoarthritis of the knee. HydroxyColl bone graft substitute will be evaluated when utilized in Open Wedge High Tibial Osteotomy with medial plate fixation. Its safety profile will be evaluated as defined by the number of reported adverse events.

Rheumatoid arthritis is a chronic systemic disease, which is characterized by chronic inflammation in the synovial tissue. Rheumatoid arthritis ultimately results in the destruction of cartilage, bone and ligaments and joint deformity. The underlying hypothesis is that autologous bone marrow-derived mesenchymal and specific populations of stem cells has anti-inflammatory and regenerative effects and thus potentially alleviates the progression of rheumatoid arthritis. The study is to explore the safety and efficacy of BM-SC transplantation in treatment of rheumatoid arthritis.

Background: Almost half of the Swedish population are overweight or obese. This will probably affect the incidence of osteoarthritis since overweight is a strong risk factor. Osteoarthritis consultations is expected to increase with 30-50% within the next 20 years. Today, in Swedish primary care, both physicians and physical therapists are primary assessors for patients with suspected knee osteoarthritis. A task shifting with physiotherapists as the only primary assessor could increase the access rate to physicians in primary care for patients with more severe disorders. Yet, it is unclear what effects these different healthcare processes have and the costs of it. Purpose: The overall purpose of this study is to perform an economic evaluation of two healthcare processes, where a healthcare process initiated by a physiotherapist is compared with when it is initiated with a physician for patients with suspected knee osteoarthritis. Methods: 100 patients will be randomized either to a physical therapist or to a physician for first assessment, diagnosis and treatment. Measurements of health-related quality of life and costs for visits to physical therapist, physician or other healthcare provider, drug prescriptions and sick-leave will be collected. A cost-effectiveness analysis will be conducted, presenting incremental cost-effectiveness ratio (ICER) and a non-parametric bootstrapping will be conducted to demonstrate the uncertainties surrounding the ICER. Expected results: It is expected that this randomized controlled study will show the effects on quality adjusted life years, cost-efficiency and cost-utility of two different primary assessors for patients with suspected knee osteoarthritis consulting primary care. The results could clarify which profession that is most appropriate to be the primary assessor for patients with suspected knee osteoarthritis in primary care.

Knee osteoarthritis (OA) is one of the common diseases which causes pain and disability with increasing age. In developed countries, it is said to be one of the ten diseases which decreases functionality most.
