Active clinical trials for "Osteoarthritis, Knee"

This study investigates the effects of unloader knee brace, biomechanical footwear device and exercise therapy on pain, physical function and quality of life in patients with knee osteoarthritis. The aim is to find more effective treatment strategies to delay or prevent heavy knee replacement surgeries.

X-rays are the most frequently used imaging test when evaluating the knee for joint replacement. They are non-invasive, safe and cost effective. They allow assessment of: progression of disease, appropriateness for joint replacement, in particular unicompartmental knee replacement (UKR), as well as likely prognosis following replacement. Despite a multitude of standardised views there is a lack of consensus regarding the optimum views to evaluate joint space narrowing within each compartment (lateral, medial and patellofemoral). This study will evaluate the status of knee cartilage in 225 patients with varying degrees, and patterns, of knee osteoarthritis (OA) using standing extension anteroposterior, 15 degrees flexion posteroanterior, 45 degrees flexion posteroanterior and valgus and varus stress views as well as MRI. These results will be compared to the gold standard imaging technique of stress views as well as to direct measurements of retrieved tissue in those patients who undergo knee replacement surgery. The sensitivity and specificity of each of the imaging techniques at predicting suitability for UKR will be calculated, the optimum imaging views proposed, and ultimately the results of this study will be used to develop a decision aid, based on optimum views, to help clinicians decide between likelihood of a patient being a candidate for UKR based on pre-operative X-ray findings.

Osteoarthritis is a progressive rheumatic disease which is the most common cause of musculoskeletal pain and functional impairment, particularly in the elderly group. The most common form is knee osteoarthritis. Pharmacological, non-pharmacological and if required surgical treatment may be applied in the osteoarthritis treatment. Non-pharmacological treatment includes patient education, joint protective measures, exercise, psychological support, diet, weight loss, physical therapy modalities, use of assistive device, hydrotherapy and balneotherapy. Ultrasound therapy is one of the most commonly used physical modalities in osteoarthritis treatment. İt has a deep heating effect and increases tissue regeneration, blood flow and metabolic effects while reducing the inflammation and relaxing the muscles. İn addition, it increases the cartilage regeneration according to certain in vivo and in vitro studies. Decelerating the cartilage loss and decreasing the high volume of synovial fluid in early-stage knee osteoarthritis is important to preventing progression of the disease. Although there are some randomised controlled clinical trials that prove the effect of ultrasound treatment on pain and functionality in the knee osteoarthritis, there is no study that proves the effect of ultrasound treatment on cartilage thickness and synovial fluid amount. The aim of this study is evaluating the effect of pulsed ultrasound treatment on cartilage regeneration, inflammation and quality of life in the volunteers diagnosed knee osteoarthritis. This study is unique because it is the first study that evaluates the effect of therapeutic pulsed ultrasound on synovial fluid and cartilage thickness with ultrasonography.

Objective To evaluate the incidence of psychological problems in total knee arthroplasty (TKA) patients and examine whether perioperative psychological intervention can improve the outcomes of and patient satisfaction with TKA. Methods The investigators will prospectively collect clinical data from 400 patients who underwent primary TKA by the same surgeon at Peking University Third Hospital. The patients will be divided into 3 groups based on psychological status and intervention: the normal group comprised patients with a normal psychological status, while patients with an abnormal psychological status will be randomly divided into the intervention group, which received psychological interventions, and the control group, which do not receive any psychological interventions. The HSS（Hospital of special surgery） and WOMAC scores will be evaluated preoperatively, 3 months postoperatively and 6 months postoperatively. A self-administered satisfaction scale (very satisfied, somewhat satisfied, somewhat dissatisfied, very dissatisfied) that assessed overall satisfaction as well as satisfaction with pain relief and the ability to perform daily and leisure activities will be administered 6 months postoperatively. Hypothesis A certain percentage of TKA patients have preoperative psychological abnormalities. Preoperative psychological abnormalities can have an adverse effect on postoperative improvement in joint function and can reduce patient satisfaction. Preoperative psychological intervention can improve the prognosis of TKA patients with psychological disorders.

This study is conducted to evaluate the effectiveness of low-level laser therapy (LLLT) as an adjunct to exercise therapy in knee osteoarthritis (KOA).

Knee osteoarthritis (OA) is predicted to become the fourth leading cause of disability worldwide by 2020. and is estimated to affect more than 40 million people in Europe and 4 million people in Italy. OA has multifactorial etiology and obesity is one of the most important risk factor for knee Regarding therapy of OA in 2014, the European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis (ESCEO) published a treatment algorithm for the management of knee OA. In Step 1 of the treatment, it is recommended to initiate therapy with chronic symptomatic slow-acting drugs for osteoarthritis (SYSADOAs). Among SYSADOAs, the evidence is greatest for the effect of chondroitin sulfate (CS). Sixty overweight subjects with knee osteoarthritis (OA) were recruited and randomly allocated to a group of treatment with 600 mg/d of non-animal Chondroitin sulphate (CS) or to a placebo group. These measurements were considered: Tegner Lysholm Knee Scoring (TLKS), Western Ontario and McMaster Universities Arthritis (WOMAC) index and Visual Analogue Scale (VAS) for pain were analyzed at time 0 and at 4 and 12 weeks. Health-related quality of life by ShortForm36, inflammation by C-Reactive Protein (CRP) and Erythrocyte Sedimentation Rate (ESR) were also evaluated, together with a body composition assessment performed by DXA.

The aim of this study is to determine if vitamin D supplementation is associated with differences in short-term recovery in patients following total knee arthroplasty compared to patients who do not receive supplementation. If so, vitamin D supplementation has the potential to become widely incorporated into the routine care for patients undergoing knee replacements.

Background: Knee osteoarthritis (OA) is a serious condition and requires good adherence to interventions such as exercises to achieve optimal management. The use of smart phone technologies could be such a strategy to enhance adherence to the home exercise program (HEP) thus improve pain, physical function and lower limb strength. The study aimed to examine the effect of using an innovative smart phone app on enhancing the adherence to home exercise programs among female older adults with knee OA in Saudi Arabia and the effectiveness of this HEP which delivered through an app, on pain and physical function. Methodology: 40 females aged 50 years or older with knee OA (20 per study arm) recruited to a randomized control trial that uses a parallel study design. All participants assessed and received an education and a set of a home exercise program for knee OA, Participants randomized into the App arm (experimental group) received their HEP in the smart phone application. Participants randomized to the other arm (control group) received HEP in a paper hand-out. After enrolment, the study outcomes were assessed at week three and week six. The primary outcomes were self-reported adherence, ANPRS, and Ar-WOMAC.

The purpose of this study is to evaluate the safety, efficacy and pharmacokinetics (PK) of EP-104IAR in patients with osteoarthritis (OA) of the knee

This clinical trial is designed to determine safety and tolerability as well as the MTD of a single-dose 2ccPA and PK data in symptomatic knee OA.
