Active clinical trials for "Osteoarthritis, Knee"

Pilot, open non-controlled trial to assess the feasibility of implementing objective parameters as primary endpoints in a clinical trial with patients affected by knee osteoarthritis.

The purpose of this study is to investigate the efficacy and safety of pulsed radiofrequency of the saphenous nerve in the treatment of pain due to knee osteoarthritis (OA). The investigators will conduct real pulsed radiofrequency or sham, over the saphenous nerve during 4 separate sessions. The investigators will evaluate pain intensity, quality of life, function, and disability via clinical validated scales. The research question is whether pulsed radiofrequency can lessen knee pain and improve function and quality of life in patients with chronic knee pain due OA. It is hypothesized, that less knee pain and improved function, and quality of life after the pulsed radiofrequency sessions.

This study aimed to investigate the production of reactive oxygen derivatives (ROS) and reactive nitrogen derivatives (RNT) in female patients with knee OA, and their effects on oxidative stress by evaluating before and after physical therapy in female patients with gonarthrosis who have Kellegren-Lawrence Staging Scale Stage II and III. aimed. To this study; All female cases over the age of 40 who applied to Başkent University Ankara Hospital and were diagnosed with knee OA by a specialist doctor will be included. Method After the cases participating in the study were checked by a specialist physician, the cases that did not prevent them from being included in the study; It will be graded according to the Kellegren-Lawrence Staging Scale. Stage II and III cases will be included in the study. Sociodemographic characteristics of the patients will be recorded before the treatment. 10 sessions of physical therapy program will be applied to the patients. Treatment program 20 minutes Hot pack (HP), 60-100 Hz frequency range, 60 pulse duration and 20 minutes of conventional TENS (Enraf-NoniusBDelftechpark 39, 2600 AV, Delft, The Netherlands) with the patient comfortable feeling and 10 minutes continuous around the knee A home exercise program will be given with ultrasound (Enraf-Nonius-B Delftechpark 39; 1-MHz; 1.5 watts/cm2) to strengthen the muscles around the knees. Those with acute inflammation of the knee joint, those who underwent surgery in the knee joint for any reason or any trauma to the lower extremity, those with a history of uncontrollable high blood pressure, any neurological or vestibular problems, those who have used steroid injections in the last two months, and any For this reason, patients with systemic diseases that will affect the study will be excluded from the study. Staging criteria according to Kellegren-Lawrence Staging Scale; Stage 0: Normal Stage 1: Possible osteophyte Stage 2: Definite osteophyte, suspected narrowing of joint space Stage 3: Moderate osteophyte, definite narrowing Stage 4: Extensive osteophyte, marked narrowing, sclerosis (Kellegren and Lawrence, 1957). Biochemical analyzes: To this study; Blood samples will be taken before and after treatment from a female patient over 40 years old who was diagnosed with knee OA at Başkent University Ankara Hospital. Total antioxidant level (TAS): It will be determined by an automatic measurement method based on the fact that the characteristic color formed by the 2,2'azino-bis (3-ethylbenz-thiazoline-6-sulfonic acid) (ABTS) radical is brightened by the antioxidants in the sample added to the medium (Erel, 2004). Results will be given in mmol Trolox eqivalen/L. Total oxidant level (TOS): will be determined by automatic measurement method (Erel, 2005). The oxidants in the sample have the task of converting the ferrous ion complex to a ferric ion. Ferric ion (Fe3+) formed by oxidation of iron (Fe2+) to its more stable form (Fe2O3) creates color with xylenol orange in acidic environment. The intensity of the color measured spectrophotometrically is related to the total amount of oxidant molecules present in the sample. The measurement is calibrated with hydrogen peroxide (H2O2) and the results will be given as micromolar H2O2 equivalent per liter (µmol H2O2 equiv./L) (Sydow, 1985). Nitric oxide (NO): Serum nitric oxide concentration (Mirand et al, 2001) will be measured in a spectrophotometer according to the method (PowerWawe XS, BioTek, USA). Serum samples will be deproteinized with 10% zinc sulfate. In this method, nitrate was converted to nitrite with Vanadium (III) chloride. It is based on the measurement of the complex diazonium compound as a result of the reaction of nitrite and sulfanilamide N-(1-Naphthy) ethylene diamine dihydrochloride in an acidic medium. High-density lipoprotein (HDL): It will be run in an autoanalyzer using the Biotrol trademark kit and given in mg/dl. The results will be recorded for each individual on the information sheet.

The aim of this prospective, randomized, controlled multi-centre study is to compare the effectiveness and safety of three and five injections of standard linear hyaluronic acid (HA) versus single HA injection in terms of pain intensity and functional status in patients with knee osteoarthritis.

Knee osteoarthritis (OA) is a disease with significant levels of socioeconomic burden to the society. P The non-pharmacologic interventions in knee OA include weight loss, exercise, and physical therapy. In this study, we aimed to to compare the cost-effectiveness of inpatient and outpatient physical therapy programs in patients with knee osteoarthritis.

This is a single-site, two-arm, parallel-group randomized clinical trial (RCT). The feasibility, acceptability, and clinical effects of the nurse-led, very brief, preoperative mindfulness based intervention for hip and knee replacement patients will be investigated relative to nurse-led preoperative pain psychoeducation. A secondary sub-analysis will compare two different styles of mindfulness practice (mindfulness of breath vs. mindfulness of pain) relative to preoperative pain psychoeducation.

One-year follow-up prospective observational study involving male and female patients (over 18-years-old) with unilateral or bilateral knee osteoarthritis treated with intraarticular injection of stromal vascular fraction (SVF) treatment. Clinical, biological and radiological data before the treatment and 1-month, 6-month and a year after are collected. The research hypothesis supports that SVF treatment enhance functionality and quality of live, relieves pain and improves magnetic resonance images of joint cartilage in patients with knee osteoarthritis.

Osteoarthritis (OA) IS one of the most common joint disorders, affecting not only the joints but also the surrounding muscles, which become weak. Resistance exercise reduces pain and improves function in patients with OA of the knee. Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used by patients with OA to reduce pain and thereby maintain the ability to perform daily activities. However, there is accumulating evidence for a negative effect of NSAIDs, thus many patients with OA are treated with dietary supplementations such as glucosamine and chondroitin sulfate, and some studies show a beneficial effects on cartilage and pain. However, their effect on OA symptoms and cartilage remains controversial. Thus, it is important to investigate whether a potentially beneficial effect of glucosamine and chondroitin sulfate with resistance exercise and manual therapy in patients with knee OA.

The aim of this study is to evaluate the effect of educational information, with and without a general practitioner recommendation to exercise, on willingness to undertake exercise/physical activity for knee osteoarthritis. Eligible participants will be aged 45+ years and will not currently have osteoarthritis, knee pain, or any condition that makes them unable to exercise. Participants will be asked to complete an online survey, during which they will be randomised to one of three groups and shown different types of educational information to read. Outcome measures will be collected as part of the survey before and after participants read the educational information presented to them.

This multicentre, prospective, randomized, double-blind, active-controlled, parallel group clinical investigation is aimed to assess the safety and the clinical performance over 6 months of a single intra-articular injection of PVA Hydrogel, novel polyvinyl alcohol preparation, as compared to hyalan G-F20, (Synvisc-One®) one of the most commonly used and best performing hyaluronic acid based products, in patients with symptomatic knee osteoarthitis (OA).
