Active clinical trials for "Osteoarthritis"

This is a three-arm prospective double-blinded randomized comparative trial aimed at comparing results regarding knee pain improvement in patients with osteoarthritis (OA) of the knee awaiting total knee arthroplasty (TKA) by either a sham procedure, a geniculate artery embolization procedure or a geniculate nerve ablation procedure. Experienced interventional radiologists and anesthetists at the McGill University Health Centre (MUHC) and study affiliated centers will carry out all interventions. 72 consecutive subjects meeting the eligibility criteria, considered for knee replacement in the future. Patients will be randomized to receive either the embolization procedure, the nerve ablation procedure or a sham procedure. Monitoring of pain will be recorded using visual analog scales, pain medication use, and Western Ontario and McMaster Universities Arthritis Index (WOMAC) and osteoarthritis knee and hip quality of life questionnaire (OAKHQOL) questionnaires over a period of 1 year post-treatment or up to the time of surgery. Pain and recovery post surgery will be monitored as well in patients who do get the Total Knee Arthroplasty (TKA) before the 1 year mark.

The purpose of this study is to compare results obtained with gender-specific and traditional knee replacement systems design among women undergoing total knee replacement surgery. Women who qualify and agree to participate will be randomly assigned to receive either a traditional or gender-specific knee replacement. During surgery, measurements of bone resection and bone-to-implant relationships will be recorded. At selected time intervals, participants will be asked to fill out questionnaires regarding pain and function, will be examined by their surgeon and routinely obtained xrays will be evaluated. In addition, a subset of participants will be randomly selected to undergo gait analysis to evaluate knee motion and muscle function.

Symptomatic knee osteoarthritis (OA) is the most common joint disorder in the U.S. and a leading cause of disability. Increasing age, obesity, and previous injury increase the lifetime risk of knee OA, but these factors are also independently associated with increased cellular senescence. Senescent cells accumulate in many tissues and contribute to chronic pathologies, linked to the secretion of pro-inflammatory factors collectively known as the senescence-associated secretory phenotype. In OA, senescent cells promote production of cytokines, chemokines, and matrix-degrading enzymes involved in progressive cartilage breakdown. The senolytic supplement fisetin alters the inflammatory and catabolic cartilage responses, which may clinically lessen OA pain while also slowing progressive cartilage breakdown. The purpose of this double-blind, randomized clinical trial is to compare 2 fisetin dosing regimens versus placebo. Sixty patients with mild to moderate knee OA will be assessed at baseline and 3 months in an effort to: determine if 2 different fisetin dosing regimens lessen pain and functional impairment compared to placebo, compare progressive changes in senescent cell activity and biomarkers of cartilage degradation between different fisetin dosing regimens and placebo, and assess acceptability and feasibility of 2 fisetin dosing regimens.

Background Thumb base osteoarthritis (OA) is common in adults 40 years and over. It affects a person's ability to work, be independent and care for others. Sufferers complain of severe pain and difficulty in completing everyday tasks. The main treatment for the condition is advice on how a person can manage their condition (self-management), reduce their pain, strengthen their hands with exercises and practical tips on tackling painful tasks, sometimes providing a hand splint for support. The treatment is provided by occupational and physiotherapists. We know that this treatment helps suffers in the short term (up to three months). But the research was done in people with few other health problems and while self-management support helps provide pain relief for most people, there are some people who don't benefit. The aim of this research is to see how pain and other hand problems change over a period of six months after the start of treatment, to understand people's experience of care, and examine why some people improve, and some do not. Research Plan In patients receiving treatment for thumb base OA at four NHS sites, who are willing to take part, this research will: - Record changes in symptoms and quality of life at three and six months from when treatment began in a postal questionnaire/survey. Discuss the experience of care and people's beliefs about what makes treatment a success by interviewing a small group of patients. Analyse patient characteristics, to see if it is possible to determine how they will respond to treatment. Develop recommendations for improving care.

Clinical research participation percentages haven't always been fully representative of a given demographic. The goal is to find out which aspects of a clinical trial may make it more difficult for patients to take part or see it through. The data will be evaluated through different demographic lenses and identify trends that could help improve the experience of future osteoarthritis patients during clinical study.

The purpose of this study is to examine the impact of two surgical techniques on the outcome of the knee replacement surgery.

The purpose of this study is to compare the early migration and periprosthetic bone changes of two total knee arthroplasties fixated with two different type bone cement.

Rhizarthrosis is a form of osteoarthritis that affects the trapeziometacarpal joint at the base of the thumb, which is more common in women over 50. Genetic and hormonal factors as well as the frequency of certain physical movements may contribute to its appearance. Surgical treatment is recommended if medical treatment fails, and trapezectomy is currently considered the standard method, although 3rd generation trapeziometacarpal prostheses are also available. The aim of this study is to compare the clinical and radiographic results after surgical treatment of rhizarthrosis: prosthesis versus trapezectomy.

Participants will be randomized to undergo a High Tibial Osteotomy (HTO) with or without a knee scope. Patients will be tested in the Gait Lab, will fill out quality-of-life questionnaires, and have a clinical evaluation done preoperative and at each follow-up visit.

This study allows patients to take part of the decision making between a unicompartment knee (partial ) or a total Knee replacement . Using the measures of a decision aid questionnaire which explicitly details the risks and benefits of both procedures.The study will use subjective (reported by patient) and objective data (which will be measured) to allow the determination if one option is superior to the other. Information gathered from this study will be used to assist future patients in selecting the surgical option that best fits their life style. A feasibility pilot study of a randomized clinical trial will help to evaluate the outcomes of both procedures and help shape a multicentre Canadian study.
