Filter by:This case-control study in patients with knee osteoarthritis and pain-free control individuals aims to develop a brain biomarker of endogenous analgesia that may be used in subsequent clinical trials. Deficits in central nervous system (CNS) pain inhibition may contribute to chronic pain intensity, but quantitative sensory testing (QST) methods are limited. Incorporating brain imaging to assessments of CNS pain inhibition, by examining activity in relevant brain networks, would allow for an objective, physiologic measure of CNS pain inhibition. Preliminary data in pain-free volunteers implicate cortical activity measured with functional near-infrared spectroscopy (fNIRS) during CNS pain inhibition. Broadly, the investigators hypothesize that variability in CNS pain inhibition contributes to variability in clinical pain intensity.
Umbilical cord blood mononuclear cells contain hematopoietic stem cells (HSC), mesenchymal stem cells (MSC), endothelial progenitor cells and other pluripotent stem cells, as well as immature immune cells, which can differentiate into chondrocytes, hematopoietic, epithelial, endothelial and nerve cells. It gives the ability to promote wound healing and vascular microcirculation reconstruction, and has the potential to treat many diseasesHowever, clinical studies on cord blood mononuclear cells in knee osteoarthritis have not been reported in the literature. Therefore, this study aims to explore the safety and effectiveness of cord blood mononuclear cells in the treatment of patients with knee osteoarthritis.
The aim of the study is to compare the 6 months clinical outcome of the treatment with a single intra-articular collagen injection versus a single placebo (saline solution) infiltration in the infiltrative treatment of knee osteoarthritis. The evaluation will be performed through clinical, subjective and objective assessments.
The purpose of this study is to correlate functional outcomes and perioperative complications with tourniquet use during high tibial osteotomy.
Knee osteoarthritis is a frequent condition whose prevalence is estimated at 7.6% of the French population aged 40 to 75, or approximately 2 million individuals . Viscosupplementation (VS) is a symptomatic treatment of knee osteoarthritis recommended by a large number of learned societies. It consists of the intra-articular injection (IA) of hyaluronic acid (HA), to reduce knee pain by restoring normal joint homeostasis impaired by endogenous HA deficiency. The IA administration of HA can be performed using 2 protocols: repeated weekly injections (3, sometimes 5 injections) and single injections. To date and there is no argument to favor either protocol. Regardless of the formula used, the safety of HA is excellent (RR of adverse reaction versus saline = 1.01, 95% CI 0.96-1.07, P = 0.6). The indication for viscosupplementation is the symptomatic treatment of mild to moderate knee osteoarthritis after failure and / or intolerance of analgesics or nonsteroidal anti-inflammatory drugs (NSAIDs). In this indication, after HA injection the responder rate is in the order of 70% to 75% at 6 months and approximately 50% at 12 months. However, the predictors of the duration of effectiveness of SV are still unknown. The objective of the study is to research the factors influencing the duration of the effectiveness of SV, under real life conditions.
The objective of this project is to examine the efficacy of an innovative Telehealth Physical Therapy (PT) program for adults with knee osteoarthritis (OA) to increase physical activity over 12 weeks in adults with knee OA compared to a control group receiving web-based resources about knee OA. One hundred individuals with knee osteoarthritis (OA), who are over the age of 45, and are also looking to move more, will be randomized into a brief or expanded intervention group. The brief intervention includes an online, guided video orientation from a physical therapist to web resources for strengthening exercises, physical activity, and pain management strategies for knee OA. The expanded program includes up to 5 online consultations with a physical therapist over a 12-week period who will prescribe strengthening exercises, physical activity goals, and pain management strategies for knee OA.
To compare the efficacy and structural change of intraarticular single platelet-rich plasma(PRP) versus novel crosslinked Hyaluronic Acid(HA)(HyajointPlus) for the treatment of early stage knee osteoarthritis(OA). This was a prospective, double-blind, RCT with an allocation ratio of 1:1.
In total knee arthroplasty (TKA), the posterior-cruciate ligament-retaining (CR) and posterior-cruciate-ligament stabilized (PS) techniques are widely used depending on the individual preference of the surgeon. Comparative analysis of these two techniques is a major topic of investigation in arthroplasty research. The hypothesis of the present study is that compared with the CR technique, the PS technique is associated with a worse gait pattern. Smart-phone based gait analysis and patient-reported functional outcomes are evaluated in patients undergoing total knee arthroplasty with a CR and a PS technique, at 3, 6, and 12 months postoperatively.
Knee replacements are the second most common surgery in Canada. Most patients recover very well but research consistently shows that 1 in 5 patients still have pain many months after surgery. Doctors often prescribe opioid medications for pain after surgery (e.g. Percocet, hydromorphone, codeine). These medications can be helpful for some people, but they can also be dangerous, particularly when used for a long time. Many patients don't like the way opioids make them feel and would prefer alternative pain management strategies. Some people become addicted to opioids, have a difficult time reducing the dose of opioids, or have lasting health problems after using them. People in this study will be randomized to either have usual care or a new pathway designed to improve pain control and decrease opioid use after knee replacements. This study will have an intervention coordinator who will assess patients before surgery and who will follow up with patients regularly after surgery to make sure their pain is controlled and to avoid long-term opioid use. This study will use education, physiotherapy, psychological therapy, ice/cold, and non-opioid pain medications. As pain medications may work differently in different patients, the coordinator will check on each patient to look for pain control and assist to reduce the amount of opioids used after surgery. This study will help people have safer and more effective pain management after surgery which may lead to better recovery, higher satisfaction, and a lower risk of being harmed by opioids after surgery.
The subject is planned to carry out the clinical trails of femoral condyle prosthesis, tibial tray prosthesis and meniscus prosthesis; At the same time, in order to achieve personalized precision bone resection, the clinical trial verification is carried out on the personalized cutting guides.
