Active clinical trials for "Osteoarthritis, Knee"

The purpose of this study is to determine the dose effect of a single injectable acellular amniotic membrane derived allograft 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 when compared to a placebo.

Knee osteoarthritis (OA) is highly prevalent and a leading cause of pain that limits physical functioning in older adults. Clinical practice guidelines recommend physical exercise for managing symptoms of knee OA. As a result, several evidence-based exercise programs have been implemented in community centers. However, access to these programs is severely limited in rural settings. Considering that rural communities have a higher disease burden and higher proportion of older adults than non-rural areas, there is a critical need to (1) adapt evidence-based exercise programs for remote delivery to increase access for rural older adults and (2) develop pathways to implement exercise programs in rural health care systems that consistently reach and engage patients with knee OA. Accordingly, we aim to engage rural primary care practices (including medical directors, clinicians, and staff) to develop a clinical pathway that refers patients to an evidence-based exercise program, called Enhance Fitness® (EF), which we have adapted for remote delivery (tele-EF). Enhance Fitness is a group exercise program that is recommended by the CDC for OA management. It is available in over 800 sites nationally and is covered by Medicare Advantage plans, but it is generally not available in rural communities. In addition, we will assess the feasibility and acceptability of implementing the clinical pathway that identifies physically inactive older patients with knee OA, facilitates exercise prescription, and streamlines referral to tele-EF in a rural primary care clinic over a 5-month period.

this study will be conducted to investigate the role of hip strengthening in improving dynamic knee stability, gait parameter, lower extremity strength and disability in knee osteoarthritis

To assess the safety and tolerability of intra-articular Injection doses of Rejoint Gel after platelet-rich plasma administration in unilateral knee OA subjects.

ROMTech is focused on transforming the healthcare market by delivering lower extremity rehabilitation systems that are effective, efficient for patient use, cost-effective, and provide better patient outcomes while simultaneously decreasing rehabilitation and overall recovery times.

The objective of this study is to evaluate at 3 months in a prospective study, the effectiveness of arterial embolization of neo-vessels in patients with a painful total knee prosthesis despite a well-conducted medical treatment

Although intra-articular knee injection with platelet-rich plasma (PRP) may have better outcomes than using hyaluronic acid (HA) for people with knee osteoarthritis (OA), it is expensive to use PRP. Programs with a combination of PRP and HA (PRP+HA) showed good results in vitro and animal studies. This 2-year study aims to clarify the short- and long-term effectiveness of the PRP+HA program for knee OA. The study will recruit 60 persons aged between 50 and 80 years who have experienced symptomatic knee OA for 6 months or more and have a radiographic picture of knee OA of grades 1-3, based on the Kellegren-Lawrence scale. Those who have diabetes, fever, anemia (Hb <10 g/dl), thrombocytopenia (platelet count <150000/ml), a blood-clotting disease, knee deformity (genu valgum/varum >20 degrees), impaired leg mobility secondary to neuromuscular diseases or a bony fracture, impaired mental function, severe cardiopulmonary impairment, taking anticoagulants long-term, a history of intra-articular steroid injection in the prior 1 year, a history of knee injury involving ligaments and menisci, and a history of malignancy are excluded. All participants will be randomly divided into group A and group B. At the beginning of the study (T0), group A will receive one course of PRP+HA program and group B will receive one HA course (a single HA injection (Hyajoint) weekly for 3 weeks). The PRP+HA program includes 3 HA injections and a single PRP injection (Arthrex double syringe system). In the 6th month, alternately, group B will receive one PRP+HA program and group A will receive one HA course. The study has 3 outcome assessment tools including a self-administered Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index, measurement of quadriceps strength with a digital handheld dynamometer, and measurement of femoral condylar cartilage thickness with musculoskeletal ultrasound. The investigators will conduct those assessments in the beginning (T0) of the study and the following 1st (T1), 3rd (T2), 6th (T3), and 9th (T4) months. In the 18th month following the beginning of the study, both groups will receive a booster course of PRP+HA program. During the first week of the program, group A will receive a HA injection before the PRP injection and group B will receive the HA injection after the PRP injection. The investigators will conduct the long-term assessments in the 12th (T5), 15th (T6), 18th (T7), and 21st (T8) months since the beginning of the study.

Osteoarthritis (OA) is one of the most common form of chronic diseases in the adult population, and approximately 800 000 people in Sweden (population of 9 million people) suffer from this disease, which causes joint pain, stiffness, swelling, loss of function and sick leave. There is increasing evidence that exercise therapy is effective for patients with knee OA. However, there is little knowledge on long-term effects and what type of exercises dosage is most effective. In this present clinical trial, which is a Nordic collaborative project with researchers from different research groups in Sweden and Norway, we intend to investigate short and long-term effects comparing high dosage exercise therapy (each treatment lasting 80 to 90 min) vs. a relatively low dosage exercise program (25 to 30 min) in patients diagnosed with knee OA. Patients in both intervention groups receive three treatments a week for 12 weeks making a total of 36 treatments. Primary outcome is pain-ratings and function (The Knee Injury and Osteoarthritis Outcome Score (KOOS)). Secondary outcome concerns various health-ratings and objective functional tests. Regarding predictors for outcome, we plan also to investigate different psychosocial variables as well as patient's beliefs regarding exercise. Feasibility of how high-dose exercise therapy actually works in primary care health care settings is also planned to be reported. Patients are being assessed by blinded assessor at inclusion, at end of intervention (3 mo), and at six and 12 mo after end of treatment. We plan to include a total of 200 subjects from primary health care settings, two in Norway and two in Sweden, with radiographic-verified knee OA with knee pain and decreased function. The patients have to be within the 45 to 85 age group. Patients are excluded if they have been scheduled for knee surgery or have some other form of illness/disease that limits the exercise tolerance (e.g. heart disease or systemic/metabolic diseases or chronic obstructive airways disease). A major goal is to grade exercises so that they are performed pain-free or close to pain-free in both intervention groups. The principle of deloading is used to meet this goal using a high number of repetitions in sets as pain modulation. The results from this study will give new information about the effectiveness of graded exercise therapy in patients with knee OA, and new knowledge if outcome can be related to the exercise dosage performed.

The aim of this study is to evaluate the outcome of specific repetitive biomechanical perturbation training on motor patterns. The first hypothesis of this project is that footwear derived biomechanical challenges will convey active and passive matching biomechanical responses (i.e. kinetic, kinematic and electromyographic) trough out the musculoskeletal kinematic chain. The second hypothesis of the project is that repetitive exposure to in-situ (trough out the gait sickle) introduction to a biomechanical stimulus would generate a process of motor learning thus conveying plasticity of existing locomotor patterns and gait strategies.

Autologous platelet-secreted growth factors (GFs) may have therapeutic effects in osteoarthritis (OA) capsular joints via multiple mechanisms. The aim is to examine the effect of a platelet-derived preparation rich in growth factors (PRGFs) in OA of the knee.
