Active clinical trials for "Osteoarthritis, Knee"

Osteoarthritis (OA) is a condition affecting the whole joint and is a major cause of pain and disability worldwide. Although OA is very common, the initial steps which lead to the development of pain and tissue damage are not fully understood. In this study participants will be investigated for markers in the blood, joint and urine in people who have a diagnosis of osteoarthritis or inflammatory arthritis and are receiving a steroid injection for their condition. Markers will be evaluated in participants with osteoarthritis compared with other types of arthritis, including rheumatoid arthritis and spondyloarthritis.

A promising new approach in total knee arthroplasty (TKA) for severe osteoarthritis of the knee joint is the the kinematic aligned procedure (KA). This technique provides prosthesis-positioning based on natural and individual axes of movement. Although first series have shown satisfying results, further verification by prospective studies and final meta-analyses will be required. Thus, the kinematic alignment represents one of the few new developments in TKA. Provided that patients are willing to participate in the study, patients data are collected preoperatively and during routine follow-up examinations and evaluated prospectively. Patients will receive either a conventionally mechanical aligned arthroplasty or a kinematical aligned TKA, according to a randomized procedure. The kinematic alignment will be achieved by the use of custom-made cutting-blocks. Therefore, the patients will undergo a computed tomography of the whole leg on the affected side. This is mandatory in order to provide the individually produced cutting blocks. In order to ensure comparability, patients are stratified regarding their age and gender before inclusion. Outcome will be measured by the use of standard scoring systems regarding function, pain and ROM (range of motion) three, six and 12 months after surgery. This study is a monocentric, prospective, randomized and controlled open study.

Introduction: Hip and knee osteoarthritis (OA) was ranked in 2010 as the eleventh highest contributor to global disability. In France in 2014, non-spinal OA was the leading self-reported cause of morbidity among adults over sixty-five years of age, with a prevalence of 49.5 per cent. OA is known to be the first cause of disability in activities of daily life and a risk factor of frailty among people over seventy-five years of age. Despite its major impact on the elderly population's quality of life and health, quality of care for OA in elderly patients remains understudied. Objective: The study aims to assess the quality of care for knee and hip OA in patients aged 75 years and over.

The reduction of functional limits and disablilities induced by knee osteoarthritis as well as improvement of patients quality of life is a public health need registered amongst the priorities established by the French law of August 9th 2004 relative to Public Health policy. However, the response to this need is not limited to treatment with health products. This clinical trial in real life on ARTHRUM H 2% device aims to analyse patients quality of life treated by intraarticular injections, eventually for several years, by difference of usual clinical trials. This open, prospective, multicentric study aims to analyse, in patient care, the impact of three intraarticular injections of ARTHRUM H 2% on quality of life over a period of 6 months (D180) in the symptomatic treatment of knee osteoarthritis.

The focus of the study is to determine the prevalence and variance of self-reported knee pain characteristics in a community-derived sample of adults aged 40 years and over. It will also identify characteristics such as structural changes of osteoarthritis of the knee as well as physiological parameters and blood and urine biomarkers.

Adipocytokines play an important role in joint inflammation in patients with knee osteoarthritis as measured by ultrasound and high sensitivity protein-C reactive. Adipocytokines could be the link between osteoarthritis and cardiovascular risk factors more prevalent in these patients.

The purpose of this study is to compare the functional outcome of two different total knee prostheses in a prospective randomised study.

Wuchuan Osteoarthritis Study is a population-based longitudinal study of natural history of knee osteoarthritis and its risk factors. At baseline and follow-up visits, IPA-Q questionnaire and a radiographs at tibiofemoral (TF) joints will be taken in order to assess the relationship between physical activity and radiographic osteoarthritis worsening.

Osteoarthritis (Osteoarthritis) of the knee is a high prevalence in the population of people aged 60 years and over, when in some cases does not cause any discomfort or pain, and therefore not diagnosed. In addition, Radio graphic findings of the knee not fully compatible with the patient's symptoms, which resulted in errors in the interpretation and diagnosis. In this study, patients who suffer from two knees or unilateral pain, will take part. Participants will undergo a clinical examination, including evaluation of symptoms by an orthopedist and an X-ray imaging, which are part of the currently accepted medical diagnosis. Patients will perform PET-MRI test in order to assess whether PET MRI is a more efficient tool for active knee osteoarthritis diagnosis.

By the method of multi-mode Magnetic Resonance Imaging, 5 patients with knee osteoarthritis are selected in this trial to observe the possible differences in the brain structure and function from the 5 healthy volunteers.
