Active clinical trials for "Osteoarthritis"

Osteoarthritis (OA) is one of the most frequent musculoskeletal disorders and represents the main indication for total joint arthroplasty. Multipotent mesenchymal stromal cells (MSCs) can be easily isolated and culture expanded from bone marrow aspirates and provide an excellent source of progenitor cells for cell-based regeneration strategies due to their ex vivo differentiation and proliferation capacity. Although there are hints that MSCs derived from OA patients may exhibit altered function the role of MSCs with respect to disease development and progression of OA is not clearly understood to date. To assess whether advanced-stage OA affects MSCs' suitability for musculoskeletal regenerative therapy, in the present study, we compare proliferation and differentiation potential of MSCs from osteoarthritic versus healthy donors.

The purpose of the study is to use different x-ray and magnetic resonance (MR) imaging techniques to take pictures of the knee. There are two specific purposes to the study: whether the different x-ray and MRI techniques will give the same or different information about the knee joint and which part of the knee joint will show the biggest change using the different x-ray and MRI techniques. The study is not designed to test a hypothesis.

This study is to determine the relevancy of clinical scales for outcome measures as compared to flexion angle and other gait measures. Clinical outcomes measures in the form of the Knee Society Score and the WOMAC Score will be obtained from patients. Gait data will also be obtained from total knee replacement (TKR) patients at pre-operative and post-operative times. Gait data will be measured on unaffected normal controls as a second baseline. The hypothesis is that the subjects clinical outcome measures do not accurately reflect gait dependent outcomes amd functional performance of the total knee replacement.

This is an observational study (not a treatment study) of pain and physical functioning after total knee replacement. The study includes 5 visits, 1 before surgery and 4 after surgery. You may be eligible if you are 50 or older,will soon be undergoing knee replacement surgery, do not have a serious heart condition or certain other medical conditions, and are not taking certain types of medications. The study includes evaluation of peoples' pain, physical functioning, medication use, and physiological responses to sensory stimuli such as heat and cold.

The purpose of this study is to determine if Bone Marrow Concentrate may be successful in the treatment of osteoarthritis. Bone Marrow Concentrate is known to contain a community of cells that has been shown to have "regenerative" properties. This study is designed to evaluate the short-term clinical and x-ray outcomes of injections for hip and knee osteoarthritis. Inclusion Criteria: Subjects must be scheduled for an autologous bone marrow hip or knee injection Subjects must have a diagnosis of hip or knee osteoarthritis Subjects must be between the ages of 18 and 85 Subjects must be willing and able to sign Informed Consent Subjects must be willing and able to return for scheduled follow-up evaluations Exclusion Criteria: Subjects who have had any type of visco-supplementation in the treated joint within the last three months prior to enrollment Subjects for whom baseline data is not available

Knee osteoarthritis (KOA) patients, have impairments in gait and balance. Accurate gait and postural balance analysis is needed to detect this impairments. Nevertheless methodological quality about the recording of gait and balance analysis in KOA patients is lacking in literature.

This observational study seeks to identify and validate novel soluble biomarkers (within blood, synovial fluid, urine) which contribute to the prognostic assessment of an individual with an acute knee injury, a group of individuals in which ~50% will progress to symptomatic radiographic knee osteoarthritis (OA). 150 individuals will be followed over 5 years with clinical assessment including validated questionnaires, biological sampling and radiological imaging (X ray, magnetic resonance imaging (MRI)).

Total knee replacement (TKR) is an established treatment for knee osteoarthritis and leads to a satisfactory outcome in over 75% of patients. The pain and function after TKR can be dependent on the accuracy of initial implantation, as deviation of more than 3 degrees from the normal alignment of the limb can lead to abnormal stresses on the implant and accelerated failure. Patient specific cutting blocks may result in a more individualised implant placement, improved pain and function following surgery, and a long-lasting implant. This trial is designed to investigate if there is any benefit to bespoke instrumentation in terms of pain and function to the patient, and an economic benefit to the NHS.

Pain is the dominant symptom of knee osteoarthritis and recent evidence suggests factors outside of local joint pathology, such as pain sensitization, can contribute significantly to the pain experience. It is unknown how pain sensitization influences outcomes from commonly employed interventions such as physiotherapy. The aims of this study are, firstly to identify people with knee OA who display signs and symptoms associated with pain sensitization using clinical tools and quantitative sensory testing. Secondly, we will investigate if indications of pain sensitization at baseline are associated with poor outcome following physiotherapy. Methods and analysis: This is a multi-centre prospective cohort study with 140 participants. Eligible patients with moderate/severe symptomatic knee osteoarthritis will be identified at hospital outpatient clinics. A baseline assessment will provide a comprehensive description of the somatosensory characteristics of each participant by means of clinical examination, quantitative sensory testing and validated questionnaires measuring pain and functional capacity. Participants will then undergo physiotherapy treatment, in line with current clinical guidelines. Follow-up post physiotherapy treatment (estimated to be at 3 months) will assess pain, disability (sub-scales of Western Ontario and McMasters University Score Osteoarthritis Index) and participants' global rating of change. These primary outcome measures will dichotomise participants into treatment 'responders' and 'non-responders' according to the Osteoarthritis Research Society International (OARSI) treatment responder criteria. For data analysis results from pressure pain thresholds, temporal summation and conditioned pain modulation will create a composite score of pain sensitization. Logistic regression will explore the relationship between response to physiotherapy and pain sensitization at baseline while accounting for various cofounders.

Hypothesis: The spa therapy treatment could improve health-related quality of life (HRQOL) in subjects with knee and/or hip osteoarthritis, and patients with rheumatoid arthritis. Main objective: Analyze if HRQOL in patients with knee and/or hip osteoarthritis, and patients with rheumatoid arthritis is modified by spa therapy treatment in the spa of Fitero (Spain). Design: Prospective observational study Participants: Fitero's spa users aged between 45-80 years old, diagnosed with knee and/or hip osteoarthritis, and also with rheumatoid arthritis. At least 40 patients of each type will be included in the study. Participants must be receiving a treatment of at least ten days. Main Variable: The scores obtained in the Euroqol5Dimensions-5Levels questionnaire (EQ-5D-5L) (for all subjects), the Western Ontario MacMaster Universities Osteoarthritis Index (WOMAC) questionnaire, for subjects with knee and/or hip osteoarthritis, and the Health Assessment Questionnaire (HAQ), for subjects with rheumatoid arthritis. Other variables: sociodemographic, anthropometric, clinics, and related with spa treatment. Follow-up duration: 9 months.
