Active clinical trials for "Osteoarthritis"

The purpose of this pilot study is to determine the feasibility of conducting a high quality clinical trial to investigate the effects of low intensity, pulsed ultrasound on knee osteoarthritis pain and physical function.

The study is a prospective, randomized comparison of total knee arthroplasty with the Medacta GMK Sphere® knee compared to the Medacta GMK PS knee, with comparison to data from previous trials of similar study design.

This clinical study will evaluate the early to midterm safety and performance of the JOURNEY™ II UNI UKS in patients with non-inflammatory degenerative joint disease of the knee requiring lateral or medial knee compartment replacement. Clinical, radiographic, health economic and safety outcomes will be evaluated.

The AIR Study is a multi-center, prospective, interventional clinical trial with the objective to evaluate the safety and performance of the Trammpolin® meniscus prosthesis system.

This phase 2 study is a single center, open-label study of SM04690 injected intraarticularly (IA) into the target knee (most painful) joint of moderately to severely symptomatic osteoarthritis (OA) subjects at a single dose of 0.07 mg SM04690 per 2 mL injection. This study will utilize magnetic resonance imaging (MRI) (including T1rho and T2 mapping pulse sequence MRI, three-dimensional spoiled gradient recalled [3D-SPGR] pulse sequence MRI, and whole organ MRI scoring [WORMS]), radiographic imaging, Western Ontario and McMaster Universities Arthritis Index (WOMAC) and patient reported outcomes (PROs) for data collection to assess efficacy outcome measures.

The Nor-Hand study is a hospital-based observational study including 300 patients with evidence of hand OA by ultrasound and/or clinical examination. The baseline examination (2016-17) consists of functional tests and joint assessment of the hands, medical assessment, pain sensitization tests, ultrasound (hands, acromioclavicular joint, hips, knees and feet), computer tomography (CT) and Magnetic Resonance Imaging (MRI) of the dominant hand, conventional radiographs of the hands and feet, fluorescence optical imaging of the hands, collection of blood and urine samples as well as self-reported demographic factors and OA-related questionnaires. Two follow-up examinations are planned after 3 (2019-20) and 8 years (2024-25), respectively. Cross-sectional analyses will be used to investigate agreements and associations between different relevant measures at the baseline examination, whereas the longitudinal data will be used for evaluation of predictors for clinical outcomes and disease progression.

A prospective, interventional, randomized, double-arm clinical evaluation study to examine the efficacy of AposTherapy® versus a control group, in the short-term at 6 months and in the long-term at 12 months post-treatment, with the primary efficacy assessment based on improvement in knee pain score and improvement in function in patients following diagnosis of knee osteoarthritis (OA).

The primary objective of this study is to obtain implant survivorship and clinical outcomes data for the commercially available G7 BiSpherical Acetabular Shell.

Osteoarthritis (OA) is the most prevalent cause of mobility impairment and disability in the elderly. Indications at early stages of OA include decreased organisation of the collagen matrix, loss of proteoglycans and increased hydration. Late-stage joint disease can be diagnosed with X-ray, CT, and conventional MRI, but there are no validated methods to image early changes in cartilage microstructure, which are direly needed in early phase clinical development. Newly developed therapies and evaluation techniques are required at earlier stages of disease to offset the growing numbers and costs of end-stage disease. MRI can probe soft-tissue with physical measurements that are not available through other methods. Quantitative MRI signal relaxation properties are particularly promising for assessing early changes in the cartilage composition. These relaxation properties are sensitive to water content and cartilage macromolecular structure. Mechanical joint-loading and exercise affects quantitative MRI through cartilage compression and nonuniform deformation. A study measuring MRI relaxation times and using static joint-loading weights has shown differences between OA and healthy subjects. Cartilage volume, which is expected to be related to these relaxation times, recovers within an hour after exercise in healthy runners, with the menisci lagging in their volume recovery rate. Previous exercise studies have not measured post-exercise cartilage recovery using compositional techniques, such as physiologically-sensitive T1ρ and T2, nor probed compositional responses with OA subjects. The investigators will examine a single knee of an initial 18 participants with MR. Participants will be drawn from two groups: (1) 12 participants aged 40-60 years old with clinical and x-ray features of OA and (2) 6 control subjects (matched to cases for age, sex and body mass index in a 1:2 ratio) who do not have clinical features of OA. Participants will undergo an initial (baseline) MR examination, followed by repeat MR examinations at approximately 1 month and 1 year following the baseline examination. This will allow the investigators to explore the possibility of mechanical joint-loading and exercise to differentiate early stage OA from healthy subjects and assess both the reliability of the MR measurements and the expected progression in the MR measurements in OA subjects in the absence of any disease-modifying intervention.

Multi-center study to include up to 600 subjects with knee osteoarthritis in unilateral or bilateral knees treated with Regenexx® SD in the osteoarthritic knee/s. Synovial fluid drawn from patients' knee/s prior to receiving Regenexx-SD treatment will be correlated with their clinical outcomes after treatment.
