Active clinical trials for "Osteoarthritis, Knee"

Exercise is considered the most effective, non-drug treatment for reducing pain and improving movement in patients with osteoarthritis. Diminished muscle strength is a common symptom associated with the onset of knee osteoarthritis. The evidence supports the benefit of exercise therapy, in reducing pain and improving function in subjects with knee OA, however research to date has been unable to quantify the disease-modifying effect of any form of exercise. The primary objective of this study is to evaluate how the use of a seated compact elliptical machine (Cubii JR1) exercise program in conjunction with a standard physical therapy regimen will impact the health of individuals with knee osteoarthritis.

The aim of this research is to determine the Effects of facilitatory Kinesio-taping and concentric quadriceps strengthening on gait parameters in knee osteoarthritis. Randomized clinical trials will be done at Physio Experts Clinic, Islamabad. The sample size is 38. The subjects were divided in two groups, with 19 subjects in Group A and 19 in Group B. Study duration was of 6 months. Sampling technique applied was Non probability Convenience Sampling technique. Both males and females of aged 50-60 years with Knee OA grade 2 or 3 were included. Tools used in the study are Numeric Pain Rating Score (NPRS), dynamometer, WOMAC questionnaire and Mobile app for measuring Temporospatial gait parameters.

The methodology developed and improved in the dissertation will be introduced into the work of the clinical Departments of Traumatology, Orthopedics and Disaster Surgery, studying the learning curve.

The aim of this randomized controlled study is to investigate whether the implementation of Blood Flow Restriction, in which the de-loading factor is delivered by the combined progressive de-loaded walking to running activity on an antigravity treadmill (treatment group), is more effective than the same antigravity protocol alone (control group). Participants will be divided as follows: Intervention group: anti-gravity treadmill combined with blood flow restriction Control group: anti-gravity treadmill Both groups will also undergo a standardized knee Osteoarthritis management through an aerobic and strength program.

For the first time in Russia, it is planned to introduce a system of personalized preoperative planning, applying the concept of kinematic alignment in robotic knee arthroplasty. Aim: to improve the results of robotic knee alignment by developing and implementing a personalized approach in preoperative planning. Objectives: to develop a system of personalized robotic knee arthroplasty; implementation of the system in clinical practice, to determine indications, contraindications; study of the results of personalized endoprosthetics, comparison with the results of mechanical alignment; detection of complications; development of an algorithm and protocol for personalized endoprosthetics. It is planned to conduct an open retrospective and prospective clinical study in parallel groups. The study is planned to include 150 patients with osteoarthritis of the knee joint stage 3-4 (according to Kellgren-Lawrence). The methodology developed and improved in the dissertation will be introduced into the work of the clinical Departments of Traumatology, Orthopedics and Disaster Surgery, studying the learning curve.

The purpose of this research is to investigate if a 12-week program of stimulation assisted activities can combat disuse atrophy for individuals diagnosed with knee osteoarthritis (KOA). This study will use a home-based medical device to administer electrical stimulation and measure its effect on outcomes that include quadriceps strength, perceived functional capacity, pain, and walking performance. It was hypothesized that stimulation assisted activities will show larger muscle mass and strength improvements; improved gait kinematics, pain and perceived function; and a high compliance to the assigned program compared to no stimulation.

The hypothesis is that the use of spa therapy in Saint-Lary Soulan for knee osteoarthritis treatment would have a therapeutic effect on this pathology. The main objective of this external comparison study is to evaluate the comparative effectiveness at 6 months of spa therapy in the Saint-Lary Soulan spa center on functional disability and pain (MCII: Minimal Clinical Important Improvement) in knee osteoarthritis compared to the control group of the Thermarthrose multicenter randomized clinical trial, receiving standard cares. The patients included in the Larytherm cohort will undergo a three-week spa therapy in Saint-Lary Soulan with a follow-up of 6 months after the end of spa therapy.

Knee osteoarthritis is a debilitating disease that can cause severe knee pain and significant limitations to patients' activities of daily living. Total knee arthroplasty (TKA), also known as knee replacement surgery, is a well-established and successful procedure for treatment of end-stage knee osteoarthritis. Over the years, TKA surgical techniques and implant technology have improved, resulting in better patient outcomes and implant survivorship. Despite continuous improvements being made to this high demand procedure, malalignment of component position is a well-known cause of post-operative complications, including knee pain, component loosening, and failure requiring revision surgery. Advanced techniques that utilize computer navigation or robotic-arm assistance have been developed in an attempt to avoid malalignment. Both technologies were created with the goal of improving the precision of implant positioning and implant sizing in order to improve lower limb alignment and joint line alignment. The OrthoAlign KneeAlign computer assisted navigation system is a commercially available device that uses gyroscopic limb position sensing technology mounted to intramedullary and extramedullary jigs to measure bone resection cuts in TKA that ultimately dictate implant position. The Zimmer Biomet ROSA Knee System is a commercially available, FDA-approved robotic assistant for performing TKA. It uses pre-operative x-rays to create a three-dimensional image of the patient's knee anatomy, which is used to create a pre-operative template of the implants to be used and provides intra-operative guidance for bone cuts during the TKA. The robotic system also assesses the soft tissue envelope around the knee and can assist with the soft tissue balancing of the knee arthroplasty. Alternatively, it can also be used in an imageless mode where bone cuts are performed based on intra-operative mapping using anatomic landmarks. To date, there have been no prospective studies comparing the implant positioning and patient outcomes directly of the KneeAlign system with the ROSA system and conventional TKA instrumentation techniques.

The goal of this clinical trial is to test the feasibility and effectiveness of transcutaneous vagus nerve stimulation (tVNS) to the ear on pain and autonomic function in people with knee osteoarthritis (OA). The main questions it aims to answer are: 1) whether tVNS is feasible to be used in people with knee OA; 2) whether tVNS demonstrates the trend in improving knee pain; and 3) whether tVNS has physiological effects on autonomic function (e.g., parasympathetic function) and pain perception in the central nervous system such as brain (i.e., central pain mechanisms). Participants will be asked to complete a battery of self-reported questionnaires about their demographic and behavioral information, ethnicity, pain, sleep, psychological/emotional symptoms. Subsequently, participants will complete baseline assessment where investigators will assess their knee pain severity, central pain sensitivity, and heart rate variability (a measurement for autonomic function). Then participants will receive a 60-minute tVNS. Investigators will redo the same assessment as baseline assessment after tVNS intervention to see the degree of knee pain, central pain sensitivity, and autonomic function changes. At the end of the study, investigators will assess their satisfaction level with the tVNS intervention and the feasibility of the intervention (e.g., completion rate, side effects).

The goal of this single-blind, cross-over clinical trial is to compare the immediate effect of intermittent vs. continuous walking on clinical and mechanistic pain profiles in persons with knee osteoarthritis (OA). In this cross-over trial, participants will perform two types of walking on a treadmill. Intermittent walking will involve 3 blocks of 10 minutes with 2 blocks of 5-minute rest (sitting on a chair) in-between. Continuous walking will involve resting for 10 minutes (sitting in a chair) before walking on the treadmill for 1 continuous block of 30 minutes.
