Active clinical trials for "Osteoarthritis"

Osteoarthritis (OA) is a slowly progressive, chronic and degenerative joint disease frequently seen in the knee and hip joints. OA is not only involved in degenerative changes of cartilage, but can also be a result of capsular hypertrophy, osteophytes, subchondral bone sclerosis, ulcerations, fibrillations. It progressively impairs the patient's independence, mobility and participation in social life, thus reducing the overall quality of life. Edema, stiffness, instability, decreased muscle strength, impaired range of motion and proprioceptive sensation, increased incidence of falls are seen together with the main symptom of pain. In OA, treatment options are available to manage symptoms and optimize quality of life. In clinical guidelines, evidence-based treatment for Osteoarthritis may include patient education and self-management programs that integrate weight management, structured exercise, and physical activity. Closed kinetic chain exercises have gained importance in the rehabilitation of many musculoskeletal problems in the last 20 years and have become one of the most preferred exercises. In addition, the virtual reality treatment approach, which is the most common example of technology use in rehabilitation, has also started to take place in rehabilitation studies. The aim of this project is to investigate the effects of Wii-based video-based exercise game therapy on muscle strength, proprioception, postural control and functional level in knee osteoarthritis rehabilitation.

In this work the investigators will study the relationship between chronic musculoskeletal pain and abnormal blood flow (neovascularity) around the shoulder, hip and knee. Veterans with as history of chronic shoulder, hip or knee pain and mild/moderate joint degenerative changes will be potential study subjects. Blood flow around joints will be evaluated using perfusion magnetic resonance imaging (MRI). Participants with demonstrably abnormal blood flow around their painful joint will be eligible for enrollment in a pilot study of joint embolization to treat their pain. Participants who choose to not undergo treatment will be re-assessed with MRI after one year to characterize the natural history of joint neovascularity and its relationship to pain.

Osteoarthritis (OA) is a degenerative disease of great morbidity in which therapies are typically palliative and only alleviate pain Mesenchymal stem cells ,adipose derived stromal cell are possible new chondroprotective regenerative treatment modalities. Clinical Effectiveness after administration of adipose derived stromal cells along with platelet rich plasma was investigated in 140 patients having moderate to severe knee (stage 3 and 4) Patients were evaluated and followed up for 2 year by subjective WOMAC score,six minute walking distance ,need of rescue medication Radiographic and MRI evaluation of joint space and cartilage thickness respectively

Rationale: Osteoarthritis (OA) is mainly characterized by cartilage degeneration. In knee OA, measuring the distance between the tibia and femur, known as the joint space width (JSW), is an often-used method to quantify the progression of the disease or the effectiveness of treatments, because it is an indirect measure of cartilage degeneration. However, JSW is often measured while the patient is standing (weight-bearing) with slightly flexed knees, with a flexion angle of around 7-10 degrees, while direct cartilage thickness measurements are usually performed while the patient is lying down (non-weight-bearing) with an extended leg [1]. Because of this difference in positioning, it is difficult to compare different JSW and cartilage thickness measures, as it is not clear what happens with the JSW distribution in the joint when a patient changes position between weight-bearing/non-weight-bearing and flexion/extension. In this study, we aim to identify the changes that occur in the knee of OA patients under the influence of weight-bearing and/or flexion, to enable comparing joint space measures from different positions. In this research we want to use MRI as a three-dimensional imaging technique because there is no radiation involved.. Objective: To evaluate how the 3D knee joint space distribution in knee OA patients changes under the influence of weight-bearing (upright) and flexion MRI scanning. Study design: Explorative cross-sectional study. Study population: 21 patients with symptomatic knee osteoarthritis (Kellgren-Lawrence grade 2 or 3) are included from the orthopaedics department of Medisch Spectrum Twente in Enschede. Main study parameters/endpoints: The primary study parameter is the change in medial joint space width between the different positions (weight-bearing/non-weight-bearing and flexion/extension).

The objective of this study was evaluation of the effectiveness of REBT on the emotional state of orthopedic patients with comorbidities before and after arthroplasty.

Osteoarthritis (OA) is the most prevalent form of arthritis. Its pathogenesis remains poorly understood. Though historically regarded as a disease of mechanical degeneration, it is now appreciated that inflammation plays an important role in OA pathogenesis

This study is intended to prove the efficacy and safety of ultrasound-guided pulsed radiofrequency therapy on adductor canal nerves by patients with Knee osteoarthritis.

The present study is a prospective cohort study. This study will be conducted to determine the change in miRNA levels with exercise in knee Osteoarthritis (OA) patients. The main questions that the study aims to answer are: Question 1: Does exercise therapy affect microrna expressions in patients with knee osteoarthritis? Question 2: Does exercise therapy affect quality of life, pain, functional status and depression level in patients with knee osteoarthritis? Participants; demographic information such as age, height, weight will be questioned. Exercises will performed twice a week under supervision and once a week as home program for eight weeks. Before and after exercise treatment, peripheral venous blood samples will taken from both groups. miRNA-146a, miRNA-155, miRNA-221-3p and miRNA-145 gene expressions will studied with the real-time PCR (polymerase chain reaction) method. miRNA-146a, miRNA-155, and miRNA-221-3p, miRNA-145 gene expressions will studied with the Real-time PCR method. The pain will evaluated with the Numeric Rating Scale (NRS), functional status with Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), depression level with the Beck Depression Inventory (BDI), and quality of life with Short Form-36 (SF-36).

The goal of this cross-sectional case control study is to investigate the cardiovascular risk in digital osteoarthritis. This study aims to compare the cardiovascular risk between group of patients with digital osteoarthritis and control group of patients with non-osteoarthritis disease paired by measurement of carotid intima-media thickness. All participants will undergo an ultrasound scan to measure carotid intima media thickness, a clinical assessment with the rheumatologist and a cardiovascular risk assessment.

Osteoarthritis is characterized by progressive degeneration of articular cartilage, weakening of subchondral bone, synovial inflammation, meniscal degeneration, and intra-articular osteophytes.
