Knee osteoarthritis (OA) is the most prevalent form of arthritis and race is a risk factor for poor outcomes. Non-Hispanic Black individuals (NHB) report greater disability and pain severity compared to Non-Hispanic Whites (NHW). These differences are reinforced through social and biological mechanisms, ultimately resulting in disparities in pain experience and associated quality of life. National efforts to reduce analgesic utilization highlight the critical need for safe, effective, and accessible alternatives for pain relief for underserved/at-risk populations. Low-carbohydrate diets (LCDs) reduce inflammation and pain independent of weight loss, indicating that diet interventions offer a non-pharmacological alternative. However, racial differences exist in metabolism that are rarely addressed in diet intervention studies. Therefore, a LCD may have greater pain-reducing effects in NHBs and provide an alternative treatment for pain. This will be the first study to examine the efficacy of these diets to reduce knee OA pain with an emphasis on race and interactions with biopsychosocial variables. Aim 1: To investigate the efficacy of the LCD to reduce pain and improve QOL. Hypothesis 1: The LCD group will show significantly greater reductions in: self-reported pain and evoked pain when compared to the USDA diet. Hypothesis 2: The LCD group will show greater improvements in: QOL, mood, and self-reported improvement. Hypothesis 3: Both diets will result in improved pain disability, severity, catastrophizing and pain-related fear; the LCD will outperform the USDA diet. Objective 2: To explore racial differences in diet effects and baseline measures. Hypothesis 1: NHBs will show greater improvements in pain, QOL, and mood. Hypothesis 2: NHBs will report greater food insecurity and less proximity to grocery stores. Hypothesis 3: Diet quality will be negatively associated with baseline pain sensitivity. Objective 3: To determine whether physiological variables contribute to diet effects or lack thereof. Hypothesis 1: Baseline physiological measures will predict: pain sensitivity and reductions in pain. NHBs will show greater inflammation at baseline than NHWs. Hypothesis 2: Change in physiological measures will be related to: change in pain, change in QOL, self-reported improvement and mood. NHWs will show greater reductions in inflammation and adiposity than NHBs.
Osteoarthritis is a painful long term joint condition that is associated with poor quality of life. There are no treatments to prevent it. Inflammation is one cause of osteoarthritis. This inflammation is complex. It involves many joint tissues, like cartilage and fat. It also involves many proteins that act as inflammatory 'signals'. Safely targeting these proteins with medications has so far proved ineffective. Physiotherapy and weight loss can help osteoarthritis, but there is a need for other approaches. Blueberries are rich in natural chemicals called polyphenols; these have well-established anti-inflammatory effects. Blueberries and other fruits may improve osteoarthritis symptoms, but the investigators do not know how this improvement happens. It may be that these foods reduce inflammation within the joint tissues. They will investigate this. This will help us to understand 1) how blueberries improve osteoarthritis symptoms and 2) whether dietary supplementation with blueberries could slow down joint damage in osteoarthritis, rather than just improving symptoms. Additionally, high levels of joint inflammation predict poorer recovery from joint replacement surgery. Therefore, blueberry supplementation may hasten this recovery. Fifty eight people scheduled to have a knee replacement for osteoarthritis will receive either six weeks blueberry supplementation or a placebo pre-surgery. Participants will continue the supplementation for six weeks after surgery. First, this study will use tissue samples (cartilage, fat and the joint lining called synovium) obtained during surgery to investigate the effects of pre-operative blueberry supplementation on markers of joint inflammation. Second, this study will assess the ability of dietary supplementation with blueberries to improve the symptoms of osteoarthritis. Finally, this study will investigate the effect of blueberry supplementation on recovery from total knee replacement. Our investigations may provide evidence to support dietary supplementation with blueberries to slow down osteoarthritis progression and to improve recovery from osteoarthritis joint replacement surgery.
Osteoarthritis (OA) is the most prevalent chronic joint disorder worldwide and is associated with significant pain and disability. Incidence and prevalence of osteoarthritis rise with increasing age. The prevalence of OA knee in Bangladesh seems to be higher due to poor working conditions, heavy physical labor, and occupational injuries which increase in the future. This will ultimately create a higher clinical and socioeconomic burden on the population and national economy. The course of the disease varies but is often progressive. OA of the knee is one of the common self-reported musculoskeletal pain conditions causing patients to visit the Physical Medicine and Rehabilitation (PM&R) department, at BSMMU. The primary objectives of knee OA treatment focus on pain reduction, and joint mobility improvement, as well as the reduction of disease progression and preserving patients' independence and quality of life. Current treatments aim at alleviating these symptoms by several different methods: Non-pharmacological treatments, Pharmacological treatments, and Invasive interventions. Mesenchymal stem cells (MSCs) therapies for knee osteoarthritis are being investigated in various corners of the world. Both positive and negative findings were observed in that research. Although, the effectiveness of MSCs in KOA is not yet well known. Some studies found MSCs effective, and safe in KOA, and it has the potential to regenerate/heal degraded joint cartilage. MSCs can differentiate into cartilage tissue. Furthermore, MSCs have been shown to have paracrine anti-inflammatory and immunomodulatory effects by producing different growth factors and cytokines. This therapeutics option is under investigation to date. The objective of this trial is to find the effectiveness, safety, and dose difference of adipose tissue-derived stem cells (AT-MSCs) therapy for the treatment of knee osteoarthritis (KOA). But in fact, there is no published data about the effectiveness of autologous adipose tissue-derived mesenchymal stem cells injection on pain, joint functioning, and femoral cartilage thickness in the management of knee osteoarthritis in Bangladesh. Henceforth, this trial will generate new knowledge about the effectiveness, safety, and appropriate dose of AT-MSCs for KOA. So this research will be helpful to generate evidence-based information for an effective treatment option for the management of KOA.
The goal of this clinical trial is to evaluate the Efficacy and Safety of AqueousJoint Intra-Articular Injection in Mild to Moderate Knee Osteoarthritis of AqueousJoint. The main questions it aims to answer are: - To demonstrate superior efficacy of AqueousJoint administered via intra-articular injection versus placebo during the study period. - To evaluate the efficacy of two different concentrations of AqueousJoint, administered via single IA injection as compared to control group (placebo) One IA injection of AqueousJoint or Placebo will be injected to participants' knee. Follow up will take place up to six months.
Taping is a non-invasive technique that has been used for various musculoskeletal conditions, including knee OA. However, there is limited research on the effects of combination taping techniques on disability, functional capacity, and knee isokinetic torque in patients with knee OA.
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 the research is to evaluate the safety and efficacy of injection of adipose allograft matrix (AAM) to the small joints of the hand for treatment of early stage osteoarthritis. The hypothesis is that use of AAM injected directly into the joint will show improvements in pain and disability while providing a safe, off-the-shelf alternative which can obviate the need for, and risks associated with, current treatment options with autologous fat transfer. As standard of care, routine strength, pain scale scores (VAS) and range of motion will be recorded, a baseline disability survey (DASH score) will also be administered. After these have all been recorded and administered in a separate visit the patient will undergo the lipofilling procedure. The subject population will include patients over the age of 18 who present with joint pain of the hand with radiographic evidence of 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.
