Active clinical trials for "Osteoarthritis, Knee"

The aim of this study is the safety and efficacy of autologous very small embryonic-like stem cells(VSELs) to knee osteoarthritis.

The purpose of our study is to determine if anatomic/kinematic total knee arthroplasties (TKAs) are superior to mechanical axis-referenced TKAs with respect to determinants of gait functionality, patient satisfaction and other objective tests of knee function as a potential indicator of long-term prosthesis outcomes. To our knowledge there has not been any literature comparing TKAs using the kinematic and mechanical axes with respect to gait analysis. A single study has compared gender-specific TKAs and found that there is no difference with respect to determinants of gait when using these prostheses (Thomsen et al, 2012), but again this study was not based on referencing off of the anatomical/kinematic axis of the knee. Our group is hoping that the small variability that may be detectable with the precision of gait analysis may be used as a predictor of future prosthesis outcome measures.

This study aims to develop, evaluate and translate highly accelerated imaging sequences (each protocol under 5 minutes) for in-vivo knee Osteoarthritis applications on a standard clinical 3T scanner using novel compression sensing and parallel imaging strategies.The overarching objective of the study is to establish a non-invasive imaging biomarker based on the development of rapid relaxation mapping with compressed sensing (CS) that will be clinically useful for assessment of early Osteoarthritis. A total of 90 subjects including 30 patients with high risk of developing knee osteoarthritis (OA), 30 patients with mild OA and 30 healthy controls will be accrued.

The purpose of this study is to test whether adding a treatment using pain neuroscience education (PNE) and multimodal physiotherapy to usual care, in subjects with knee osteoarthritis and pain catastrophizing, who are scheduled for a total knee arthroplasty (TKA), is more effective than only usual care. There is a high evidence level of different systematic reviews, which support the efficacy of physiotherapy treatments combined with behavioural/educational techniques aimed to reduce pain catastrophism, pain and disability in other pathologies. The primary aim of that kind of interventions is to help the subjects to reconceptualise its own pain understanding and its role on the recovery process, as well as promoting an increase of activity and encourage the subject to resume its usual activity instead of continuing to avoid it.

A prospective cohort study to study the effectiveness and safety profile of geniculate artery embolization for the treatment of symptomatic knee osteoarthritis.

This study will address the scarcity of research and the variations in recommendations regarding the effects of strength and balance training to reduce the fall risk in knee osteoarthritis patients.

Total knee arthroplasty (TKA) may be associated with significant blood loss, and transfusion carries substantial risk of immunologic reaction and disease transmission. Several methods reportedly reduce postoperative blood loss and avoid homologous blood transfusion with traditional TKA approaches. Drain clamping was one of the widely used method and tranexamic acid administration was the recently adjuvant method to reduce blood loss in TKA. However, there were several regimens in either drain clamping or tranexamic acid administration reported in previous studies. Our objective was to compare the efficacy of our drain clamping protocol and/or tranexamic acid regimen for reducing blood loss and transfusion in TKA.

This study will test the effectiveness of CF101 in treating the symptoms of osteoarthritis (OA) of the knee. Eligible patients will be given either CF101 or matching placebo tablets and their symptoms will be evaluated over the 12 week treatment period.

People with rheumatic disorders (arthritis) often have trouble keeping their jobs. This study will look at whether vocational rehabilitation (VR) will improve the ability of employed people with arthritis to keep their jobs. Job retention VR services target key factors that increase the risk of job loss. They aim to modify jobs to reduce barriers caused by functional limitations and disease symptoms, future career planning, and establish a partnership with a VR counselor for ongoing help. We will conduct the study among patients with rheumatic disorders recruited in eastern Massachusetts. We will give 120 study participants job retention services provided by VR counselors. We will give another 120 participants literature about employment- related resources. We will compare the outcomes of the two groups to evaluate the usefulness of job retention services in preventing job loss in people with rheumatic disorders.

The purpose of this study is to determine the dose effect of a single injectable acellular amniotic membrane derived allograft injection for the treatment of knee osteoarthritis and to confirm whether the use of 2 mL of the same amniotic injection offers a statistically significant advantage over the 1 mL injection.
