Filter by:The purpose of this study is to evaluate and compare the clinical, radiographic (x-ray) and cost effectiveness outcomes (cost relative to risks and benefits) of two different minimally invasive knee joint replacement surgical techniques. The primary study hypothesis is that in comparing total knee replacement performed with the two different surgical techniques that respect four minimally invasive surgery principles (low-profile instrumentation, "minimally invasive" incision, overall minimal knee surgical intervention), a faster return to function will result when the technique does not incise the tendon.
This is a 2-year double-blind randomized controlled trial in 287 community-dwelling individuals age 60 years or older undergoing uni-lateral total knee replacement due to severe OA of the knee.We compare an oral dose of 2000 IU vitamin D3 per day to 800 IU. The primary endpoints are pain and disability related to rehabilitation of the operated knee,and related to the expected high prevalence of OA in the contra-lateral knee. Secondary endpoints are change in 25(OH)D levels, muscle strength, balance, lower extremity function, the rate of falls, bone density and bone quality, bone metabolism, general pain, fall-related fractures, body composition, blood-pressure, major cardiovascular events, blood glucose-insulin levels, executive cognitive function, rate of upper respiratory tract infections / all infections, tooth loss, dental health, health care utilization, number and size of facial skin keratosis, and radiographic progression of the non-operated knee. Pain and disability will be assessed by the pain and function subscales of the Western Ontario- McMaster Universities Osteoarthritis Index (WOMAC). Randomization will be stratified by WOMAC function prior to surgery, radiological evidence for OA in the contra-lateral knee, and hospital. Clinical visits will take place at baseline (6-8 weeks after TKR), at 6, 12, 18 and 24 months of treatment. In addition, all individuals will receive a phone call every 2 month to assess adverse outcomes and compliance to treatment, supported by a hotline for immediate report of adverse events. Statistical power: We expect more than 80% power with 200 participants completing their 24 month follow-up, and 260 participants completing their 12 month follow-up. This is a trial with medicinal product.
Knee osteoarthritis (OA) accounts for a significant proportion of mobility limitations and is one of the most disabling problems facing the growing population of older adults. The long-term objective of this research is to reduce disablement of older adults with symptomatic knee OA. The principle of specificity of training indicates that exercises that closely approximate the goal functional activity are most effective in improving physical performance during that activity. Based on this principle, the specific aim of this pilot study is to design a patient-specific gait training intervention using analysis of compensatory joint moments and energy expenditure. Successful completion will inform rehabilitation for maintaining or improving mobility as well as explore the mechanism of effect.
This pilot study will test the testing and exercise training protocols for a larger study that is in the desing phase and may be modified based on the findings of this study. Two exercise groups will be compared; one is a stadard treatment group using leg strength exercises that are commonly employed in therapy clinics. The other group will do balance and agility type exercises, but no specific strength exercises. These "KBA" exercises are increasingly common in therapy clinics, but very little research has been conducted on their effectiveness in treating knee osteoarthritis symptoms. Participants in this study will complete three short paper and pencil tests at the beginning and end of the study (8 weeks of exercise) as well as a leg strength test, a leg endurance test, two short walking tests, and a stair climb/descend test. One of the paper and pencil tests will be taken every two weeks in an effort to see how quickly changes to symptoms might occur. The exercise programs will be conducted 3 afternoons per week (Mon-Wed-Fri) and will be lead by an ACSM certified instructor.
Derris Scandens Benth (family : Leguminosae) is a woody vine growing throughout Southeast Asia, including Thailand. The stem of D.Scandens has been widely use in Thai traditional medicine, foe example of myalgia. Previous study shown that D.Scandens Benth extract has the anti-inflammatory activity. Although NSAIDs are efficaciously in the treatment of osteoarthritis,but the GI side effect is still concerned. In this study we aim to investigate the efficacy and safety of D. Scandens Benth extract compared with Naproxen for therapy of patients with knee osteoarthritis.
The purpose of this study is to evaluate whether tapentadol (CG5503) prolonged-release (PR) tablets at doses of 100-250 mg twice daily provide a better pain relief in patients with moderate to severe chronic pain due to osteoarthritis of the knee than a placebo (a medication without active substance). In addition the tolerability of CG5503 PR will be assessed. One third of the patients will receive CG5503 and one third will receive placebo. For further comparison one third of the patients will receive oxycodone controlled release (CR) at doses of 20-50 mg twice daily which is an active approved pain medication. Please note that tapentadol ER (Extended Release) and tapentadol PR (Prolonged Release) are identical and used interchangeably. This is due to United States of America and European naming conventions.
International recommendations (ACR,EULAR) emphasize physical exercise and weight loss for patients suffering from knee osteoarthritis. Nevertheless, number of patients receiving advices for these 2 points still low. This study evaluates the impact of a standardized medical intervention (patient education, weight reduction and physical exercise) in knee osteoarthritis patients.
Context: The many treatments and devices developed to unload the diseased articular surface in knee osteoarthritis have provided limited solutions. A novel biomechanical device comprising of four individually calibrated elements attached onto foot-worn platforms was recently developed. This device is capable of such unloading during standing and walking, simultaneously strengthening dynamic stabilizers and training neuromuscular control by controlled biomechanical perturbations. Objective: To asses the effectiveness of this device in reducing pain and improving function in patients with knee osteoarthritis. Design and Setting: Randomized, controlled and double blind prospective trial, conducted from September 2005 to February 2006, in the Department of Orthopedics, Asaf Harofeh Medical Center (Zerifin, Israel). Patients: Sixty-one patients with diagnosed knee osteoarthritis who self-reported moderate-to-severe level pain. Interventions: Patients were randomly assigned into active and control groups and underwent 8 weeks of treatment. The active group was treated with the device and its four biomechanical elements that had been individually calibrated to accommodate a pain-free joint alignment. The control group was treated with the device’s platforms without the biomechanical elements. Primary Outcome Measures: The patients were evaluated three times during the study: at baseline, after 4 weeks and at the 8 week endpoint. Primary outcomes were the Western Ontario and McMaster Osteoarthritis Index (WOMAC) and the Aggregated Locomotor Function (ALF) assessment.
Pain is the main symptom of osteoarthritis that motivates medical visits. Diacerhein has already demonstrated its efficacy in knee and/or hip osteoarthritis. This study aims at confirming the efficacy of diacerhein in symptomatic knee osteoarthritis using known and validated criteria and according to the recommendations and guidelines for this kind of study.
The five-year goal of this project is to investigate the effect of in-shoe wedged orthoses on lower extremity function in patients with knee osteoarthritis. In general, our aims address the immediate effects of orthoses, the long-term effects of orthoses, and the immediate and long-term treatment effects comparing medial versus lateral wedged orthoses. The investigators hypothesize the wedged orthosis will result in altered gait mechanics that reflect a reduction in knee joint forces, reduced knee joint pain and increased function during weight bearing activities.
