Active clinical trials for "Osteoarthritis, Knee"

Non-surgical treatment options, like exercise therapy, show excellent short-term effects regarding pain reduction and improvement of knee function. However, mid- and long-term effects are missing so far. This might indicate that long-lasting changes in motor-skill performance (Motor Learning) have not occurred. Motor learning is associated with permanent changes in the capability for skilled movement behavior avoiding unfavorable joint loads and inappropriate muscle activation patterns, leading to compensatory movement strategies. One-sided and high repetitive loads in the knee joint could be one reason for the progression of knee osteoarthritis. Physiotherapeutic strategies should therefore be able to stimulate motor learning processes. In physiotherapy, motor learning can be optimized by using instructions and feedback, targeting an external focus of attention, when learning specific movement patterns. This study investigates the effects of a 12 week exercise therapy program, using an external focus of attention, on functional and biomechanical parameters in patients with knee osteoarthritis. To measure possible changes, functional measurements are taking place at baseline, after 6, 12 and 24 weeks. The biomechanical measurements (3D gait analysis) are taking place at baseline, after 12 and 24 weeks.

To investigate whether the use of valgus knee brace is useful for patients with medial knee osteoarthritis.

Although the effects of different exercise dosages for patients with osteoarthritis are compared in the literature, it is seen that studies on which exercise dosage is better are insufficient.The planned study has 2 main objectives: To examine the effects of different exercise dosages on exercise dependence To investigate the effect of different exercise dosages on pain and functional results

Total joint replacement is an efficacious treatment for osteoarthritis of hips and knees. Both total knee replacement (TKR) and total hip replacements (THR) have excellent implant survivorship. However, patients' satisfaction is lower in TKR than THR. A possible cause of the discrepancy is the unnatural knee kinematics after TKR. Various implants designs have been developed to solve the problem. The most common fixation mode is cemented TKR with good survival up to 15 years. However, newer series in younger patients also have shown lasting survival with uncemented implants (Nilsson et al 2006, Prudhon et al. 2017). Among various different designs, medially stabilized total knee, which are designed to reproduce natural knee kinematics with medial ball-in-socked design, is a promising implant (Australian registry report 2018). Dynamically the medial pivot knee performs more naturally (Bragnazoli et al, 2019) compared to other designs. Most data for this design is available only for the cemented version. Up to now there is no safety study performed that confirms the stability over time for this implant with uncemented fixation. In this study, we will therefore analyze the in vivo stability of an uncemented knee implant with medially stabilized design. Our study will contribute to the understanding of fixation and lead to safety to the patient.

Adolescents and young adults who hurt their knees playing sports or doing recreational activities can develop joint damage, muscle weakness, inactivity, and weight gain which might lead to an increased risk of osteoarthritis (OA), a disabling joint condition in their later lives. Despite knowing that muscles and joints benefit from exercise, there is no proven exercise-based treatments to delay or even halt the onset of OA after a knee joint injury. The current study will assess if a physiotherapist-guided intervention called Stop OsteoARthritis (SOAR) improves knee muscle strength, physical inactivity, knee-related self-efficacy, and knee-related quality of life in people at risk for osteoarthritis due to a past knee injury. A total of 70 former knee injury participants will be randomly assigned to two groups. One group will immediately start a 16-week SOAR program, while the second will wait for 9-weeks before starting an 8-week SOAR program. Trained physiotherapists will deliver the SOAR program with videoconferencing. The study hypothesis is that participating in the 8-Week SOAR program will improve the knee muscle strength, physical activity levels, knee-related self-efficacy and knee-related quality of life in people discharged from regular healthcare after a sports knee injury. The findings will help researchers understand the ideal length of the program for a future clinical trial in real-world settings.

The subject continues the research of Professor JiaKuo Yu's research group on the personalized design, processing and manufacturing of personalized total knee replacement artificial joint prostheses and the verification of animal and human cadavers. It is planned to carry out the femoral condyle prosthesis of personalized total knee replacement prosthesis. Clinical trials are carried out on the body, tibial tray prosthesis and meniscus prosthesis; at the same time, in order to achieve personalized precision surgery, the clinical trial verification is carried out on the placement of personalized surgical guides that match the personalized artificial joints. In the clinical verification study, the research team will summarize the role of personalized artificial joints for total knee replacement and personalized implant surgical guides in the precise and minimally invasive treatment of knee joint diseases.

: Falls are the primary cause of injury and a leading cause of disability and mortality among older adults. Risk factors for falling are common among older adults with knee osteoarthritis (OA) - a highly prevalent condition. Physical exercise is consistently the most efficacious intervention for preventing falls in older adults. 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, the proposed project aims to refine a protocol for remote delivery of Enhance Fitness (EF). EF is an evidence-based, group exercise program involving strength, endurance, and balance training that is recommended for falls prevention and OA management

Osteoarthritis (OA) is a chronic joint disease that involves the entire joint, causing cartilage damage, bone remodeling, osteophyte formation and loss of normal joint function. Knee OA is one of the leading causes of disability in the world and thus represents a major public health problem. Knee OA treatment can be operative and non-operative. Non-operative treatment includes pharmacological treatment, changing life style and physical therapy. The goal of physical therapy in knee OA is to reduce pain and improve knee function through therapeutic exercise, especially by strengthening the quadriceps muscle. In addition to therapeutic exercise, muscle electrical stimulation is often used, and in the literature there is evidence of biofeedback therapy efficacy. Goal of the study is to investigate whether there is a difference in pain reduction, increase in quadriceps muscle strength, and improvement in knee function in patients who had only kinesitherapy, from those who underwent kinesitherapy and biofeedback, and in patients who received electrical stimulation of quadriceps muscle with kinesitherapy. 93 patients with knee OA according to ACR criteria and Kellgren and Lawrence radiological classification grades 1 and 2 will be included in study. Subjects will complete: Visually Analogous Pain Scale (VAS), Western Ontario Universities Osteoarthritis Index (WOMAC), 36 Item Short Form Health Survey (SF 36), International Classification of Functioning, Disability and Health (ICF) osteoarthritis core set, and quadriceps muscle strength will be measured by EMG biofeedback device.
