Active clinical trials for "Osteoarthritis, Knee"

The main objective of the study is to evaluate the safety, performance and clinical benefits of the Persona implant and its instrumentation in primary total knee arthroplasty

The goal of this clinical trial is to compare two different pain relief techniques (cooled radiofrequency ablation (CRFA) and hyaluronic acid (HA) injection) for patients with knee osteoarthritis (OA) over a period of 6 months. The main questions it aims to answer are: the extent of reduction of pain score and the proportion of subjects ("responders") whose knee pain is reduced by at least 50% from baseline up to 6 months after treatment in the two treatment groups. the safety of the two treatment modalities. Participants will undergo a nerve block test to determine if they would experience pain relief from blocking of nerve signals. Responders will be randomised to receive one of the two treatments for their knee pain. Researchers will compare the pain intensity of CRFA and HA injection groups at baseline, 2 weeks, 1 month, 3 months and 6 months post-treatment using validated questionnaires.

Knee osteoarthritis is the most common type of osteoarthritis in the lower extremity and constitutes 23% of all arthritis cases, about 13% of females and 10% of males aged above 60 years have symptomatic knee OA. Intra-articular corticosteroids (IACs) are a frequently-used treatment regimen for pain relief from symptomatic knee OA as it inhibits inflammation and reduces prostaglandin synthesis. Platelet-rich plasma (PRP) is an autologous blood product containing a high percentage of various growth factors (GFs), such as fibroblast growth factor, epidermal growth factor, vascular endothelial growth factor, transforming growth factor-β and platelet-derived growth factor. The aim of this study is to compare effect of intra-articular injection of platelet rich plasma versus corticosteroid in treatment of primary knee osteoarthritis.

The primary research purpose is to determine if the use of a drug therapy intervention (each study participant will be randomly assigned to receive one of 3 study medications which will be blinded from everyone, including the study participants, and all research staff (except the principal investigator), combined with a series of 3 injections of Platelet-Rich Plasma (PRP) into an osteoarthritic knee joint, leads to reductions in knee pain, and improvements in physical function. Improvements will be assessed by serially evaluating pain scores and functionality using standardized and validated questionaires which will be completed by the study participant at each clinic office visit. In addition, blood tests will be drawn at each visit to evalute any changes in blood compostion. If the participant meets the study inclusion and exclusion criteria and agrees to attend 7 follow up office visits, they will be eligble to enroll in the study. If they wish to volunarily enroll in the study, it will be explained in detail, afterwhich all questions and any concerns will be answered. Each office visit will take between 30-45 minutes and will take place over a 12-month study period comittment.

Background: Patient's pain experience is a complex phenomenon. A comprehensive clinical assessment of the patient's pain experience is helpful to define individual differences between patients and thus to plan effective individualized treatment programs. Gait assessment is an important functional task in the clinical evaluation, which allows the definition and modulation of therapeutic intervention. The influence of patient's pain experience on gait parameters is currently understudied in literature. Objective: To investigate patient's pain experience based on an assessment model proposed by Walton and Elliott in patients with knee OA. The study's second aim is to examine the correlation between the parameters of the 10 Meter Walking Test (10MWT) and Time Up and Go test (TUG) assessed by an inertial sensor and the patient's pain experience.

Through this cohort study, previous clinical data can be systematically reviewed and supplemented through clinical follow-up. Prospective enrollment and follow-up observation of subsequent patients can also be carried out to build a retrospective-prospective two-way cohort study. The intraoperative, perioperative, clinical follow-up and health economics of surgical robot, computer navigation, personalized osteotomy guide and other digital technologies and traditional TKA were comprehensively and objectively compared, the results and conclusions of the center were summarized and reported, and the effectiveness and safety of digital assistive technology applied to TKA were explored, providing references for clinical diagnosis and follow-up research.

Use of mirtazapine and quetiapine for improvement of sleep quality after TKA

This study experimentally manipulates pain catastrophizing in order to investigate the neural mechanisms by which pain catastrophizing influences the experience of pain in different ethnic groups among adults with knee osteoarthritis. Participants will be randomized to either a single session cognitive-behavioral intervention to reduce pain catastrophizing or a pain education control group.

This is a phase 2 open-label, 6 arms (1 study group and 1 control group for each joint category), randomized control group clinical study with 300 subjects diagnosed with osteoarthritis of knees (n=100), hips (n=100) and shoulders (n=100). The study subjects will be evaluated for disease-associated severity according to symptoms, such as pain, mobility, daily active life, and functions using arthritis society established specific measurement tools related to the joints (KOOS and KSS for OA-knees: HOOS and HHS for OA-hips and ASES and CSS for OA-shoulders).

In Hong Kong, joint diseases are common health problems as identified by the Elderly Health Service under the Department of Health. It accounts for most of the disability of the elderly in Hong Kong. In particular, osteoarthritis (OA) is on the rise and the prevalence of OA increases with age. Women are more likely to have OA in knee and hip joints after menopause. A study in 2000 reported that among Hong Kong people aged 50 and above, 7 percent of men and 13 percent of women suffered from OA. With an ageing population, it is expected that OA will become a major public health problem in Hong Kong and worldwide and the socio-economic cost of supportive care to these patients can become a major burden to Hong Kong society and many regions in the world. Early diagnosis and prevention of OA and effective technology for treatment monitoring are very important. At present, the management of OA is not optimal and standard quality indicators suggest that the majority of persons with the disease do not receive appropriate care. Over half of the population affected with OA are unaware of the diagnosis. The research team have developed a quantitative and fully automated non-contrast MRI application for early detection and monitoring of joint diseases. The whole project was funded by the Innovation and Technology Fund (ITF) (MRP/001/18X ) started in January 2019. This clinical trial is part of the quantitative assessment of this developed technology. The team anticipate this innovation will address both OA diagnosis, surveillance and management. This can potentially increase diagnostic capabilities with minimum efforts, improving patient awareness, and improved treatment monitoring of the disease state after the interventions. Thus, the proposed technology is expected to provide betterment in the quality of life for the elderly population.
