View clinical trials related to Osteoarthritis, Knee.
Filter by:Osteoarthritis (OA) is the most common joint disease, causing severe pain due to joint inflammation (synovitis). While total knee arthroplasty (TKA) is commonly performed to reduce pain, 20% of patients are dissatisfied with their outcome post-surgery. This dissatisfaction is caused by persistent pain post-TKA due to synovitis that is not routinely removed during surgery. To address this problem, a synovectomy can be performed during TKA, which involves resecting the inflamed layer of tissue lining the joint, called the synovium, and its associated sensory nerve endings. Since the synovium will regenerate in the months post-surgery, synovectomy only transiently reduces pain after TKA. The proposed study will help ascertain the benefits and effects of synovectomy in patients who are more likely to experience poor satisfaction (driven mostly by pain) post-TKA. This study will include 62 patients undergoing TKA due to end-stage OA who have moderate to severe synovitis, as determined by ultrasound assessment. Patients will be randomized (1:1) to undergo a TKA with synovectomy or without synovectomy. Primary and secondary outcomes will be assessed through patient-reported levels of pain and function, results from physical performance tests, and quality of life (QOL) scores. These measures will be recorded pre- and post-surgery for comparison. Through demonstrating that synovectomy can at least transiently reduce pain post-TKA, this study will provide evidence for the development of medical therapies that target the synovium to slow its regrowth. This will be transformative for the long-term management of joint pain and synovitis post-surgery, thus significantly improving patients' overall QOL.
The purpose of this study is to determine the safety and efficacy of the 40 mg and 100 mg doses of allogeneic micronized dehydrated human amnion/chorion membrane (micronized DHACM) injectable compared to 0.9% sodium chloride injection, placebo control for the treatment of knee osteoarthritis
The ForceLoss study aims to develop personalised modeling and simulation procedures to enable the differential diagnosis for the loss of muscle force, namely dynapenia. The primary causes of dynapenia can be identified in a diffuse or selective sarcopenia, a lack of activation (inhibition), or suboptimal motor control. Each of these causes requires different interventions, but a reliable differential diagnosis is currently impossible. While biomedical instruments and tools can provide valuable information, it is often left to the experience of the single clinican to integrate such information into a complete diagnostic picture. An accurate diagnosis for dynapenia is important for a number of pathologies, including neurological diseases, age-related frailty, diabetes, and orthopaedic conditions. The hypothesis is that the use of mechanistic, subject-specific models (digital twins) to simulate a maximal isometric knee extension task, informed by experimental measures may be employed to conduct a robust differential diagnosis for dynapenia. In this study, on patients candidate for knee arthroplasty, the investigators will expand (i) the experimental protocol previously developed and tested on healthy volunteers with a measure of involuntary muscle contraction (superimposed neuromuscular electrical stimulation, SNMES), a hand-grip test, measures of bio-impedance and clinical questionnaires, and (ii) the modeling and simulation framework to include one additional step (to check for muscle inhibition). Medical imaging, electromyography (EMG) and dynamometry data will be collected and combined to inform a digital twin of each participant. Biomechanical computer simulations of a Maximal Voluntary Isometric Contraction (MVIC) task will then be performed. Comparing the models' estimates to in vivo dynamometry measurements and EMG data, the investigators will test one by one the three possible causes of dynapenia, and, through a process of hypothesis falsification will exclude those that do not explain the observed loss of muscle force.
Robotic arthroplasty is increasing in acceptance on a global scale as a result of advancements in orthopedic surgery technology. The investigators aimed to share our anesthesia management experience as well as compare robotic unilateral total knee arthroplasty with conventional surgical technique in this retrospective study.
The hypothesis is that the use of spa therapy in Saint-Lary Soulan for knee osteoarthritis treatment would have a therapeutic effect on this pathology. The main objective of this external comparison study is to evaluate the comparative effectiveness at 6 months of spa therapy in the Saint-Lary Soulan spa center on functional disability and pain (MCII: Minimal Clinical Important Improvement) in knee osteoarthritis compared to the control group of the Thermarthrose multicenter randomized clinical trial, receiving standard cares. The patients included in the Larytherm cohort will undergo a three-week spa therapy in Saint-Lary Soulan with a follow-up of 6 months after the end of spa therapy.
A phase 1 exploratory clinical study to investigate safety, tolerance and efficacy of a single intra-articular injection of autoSTEM-OA or alloSTEM-OA in participants with mild to moderate knee osteoarthritis
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
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 (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 aim of this study was to investigate whether exercise-induced hypoalgesia (EIH) is present following exercise in patient after total knee arthroplasty (TKA) and if so, if it changes with exercise intensity. A repeated measures and single-blinded randomized study were done. Thirty-eight patients 24 hours after TKA were randomly assigned to either low intensity exercises (LIE) group or high intensity exercises (HIE) group. An exercise programs lasted for five days during the hospitalization period. Pain severity was assessed by Visual Analog Scale (VAS) (0-10 mm). Pressure pain thresholds (PPTs) were measured over quadriceps and biceps brachii and muscles immediately before and after exercise.
