Filter by:Introduction Osteoarthritis (OA) is a chronic, progressive disease with high disability and teratogenicity in the joints. Deterioration of the articular cartilage is the main problem associated with osteoarthritis, which decreases joint space between the two bones[1]. Clinically, patients with knee OA typically present with a chief complaint of pain, often associated with limited range of motion, stiffness, osteophytes, crepitus, and effusions. Due to the progressive degenerative nature of OA and the associated pain, patients become more physically impaired through the course of the disease [6]. One of the main tissues affected by this disease is the articular cartilage, which is a thin tissue covering the bony end in the joint that mainly provides mechanical support and lubrication during joint movement [7]. Age, previous knee injuries, but also obesity(increased body mass index(BMI)) ,joint malalignment and instability that result in increased mechanical stress are all strong risk factors for the development of knee OA [8-10]. Magnetic resonance imaging (MRI), arthroscopy examination, high-frequency color ultrasound and thermal texture maps are the four most acceptable types of imaging examinations. These examinations cannot only help diagnose KOA, but they can also assess the severity of joint damage and evaluate disease progression and treatment [11,12]. Treatment options for patients with OA include: conservative approaches, such as weight loss, physical therapy, and pharmacological interventions, while the more invasive approaches include intraarticular injections, joint preserving surgical treatment, and total knee arthroplasty (TKA). [13, 14] Radiofrequency ablation (RFA) is a novel technique that also recently gained popularity in alleviating chronic pain in patients with musculoskeletal disorders such as OA [15] Radiofrequency (RF) ablation, or modulation of the sensory innervation surrounding the knee, specifically the genicular nerves (GNs), has emerged as a therapeutic option to treat chronic knee OA pain for patients who are unresponsive to conservative treatments or are unsuitable candidates for total knee arthroplasty (TKA).

The main purpose of this study is to evaluate whether recruitment rates are adequate to power a future RCT. The secondary aims are to obtain preliminary information about safety and efficacy of topical diphenhydramine 5% ointment in patients with knee OA.
The purpose of this study is to determine the safety and efficacy of intraarticular injection of Cell-free Stem Cell-derived Extract Formulation for treatment of knee osteoarthritis symptoms.
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.
Developed a robot for minimally invasive TKA surgery and prepare for the subsequent CFDA application of the minimally invasive total knee replacement robot system.
CONNACT OA knee cohort is a prospective longitudinal cohort study where we aim to collect sociodemographic, psychosocial, clinical, health utilization and cost data in order to better understand the Asian OA knee cohort and investigate for prognostic variables that can potentially influence a patients clinical outcome and treatment decisions. In addition, the CONNACT OA knee cohort will form the basis for a cohort multiple randomized control trial (cmRCT) study design where multiple interventions can be tested in a randomized fashion. Each intervention is offered to a randomly selected sample of patients eligible for that intervention, who are then compared with the rest of the eligible patients from the cohort that are still being treated as usual.
Health care professionals are dedicated to the ongoing evaluation of the peri-operative experience, and always striving to improve patient satisfaction. There are extensive protocols and communication strategies to optimize pre-operative education, intra-operative comfort and safety, and post-operative pain control, but most strategies are carried out by the treating team. The idea of using mindfulness to empower patients to be active participants in reducing pain and anxiety has already been successful in a number of medical settings. Multiple studies have demonstrated the effectiveness of mindfulness based stress reduction and mindfulness based cognitive therapy, a modification to treat depression. Mindfulness has been shown to reduce catastrophizing, depression and disability, all of which are of concern with respect to long-term success after arthroplasty. There is limited evidence to demonstrate the usefulness of mindfulness as a peri-operative intervention. Although there is evidence that a brief mindfulness meditation session can impact experimental pain scores and anxiety, there is no current literature that has evaluated the impact of such a session as part of the peri-operative teaching protocol with respect to pain and anxiety. Our objective is to assess the capability of a short-term mindfulness intervention (serving as a compliment to the pre-operative pathway for total joint arthroplasty) to reduce peri-operative pain that can be integrated with the existing arthroplasty pathway. In addition, we explore the utility of using such a tool to reframe patients' expectation of the peri-operative period as evidence by its impact on anxiety and post-operative patient satisfaction. Thirty-two participants will be recruited and randomly assigned to either control or treatment groups. The control group will receive standard care associated with total joint arthroplasty. The treatment group will receive a 45-60 minute mindfulness meditation teaching session administered by a credentialed mindfulness instructor and affiliated with the University of Calgary Psychosocial Oncology Mindfulness Program in addition to standard care for arthroplasty surgery. The treatment group will be assigned "homework" recordings of body scan exercises and asked to listen to the recording daily for the two-week period prior to surgery. Patients will be asked to listen to their body scan meditation immediately prior to entering the operating room and daily each post-operative day while in hospital. Longitudinal assessments encompassing the preoperative, peri-operative and post-operative periods will be acquired using validated pain scores and anxiety outcomes scores including the Numerical Rating Scale (NRS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the short-form State-Trait Anxiety Inventory.
Resistance training of knee extensor muscles is being used in physiotherapy management in knee osteoarthritis (OA) to improve pain and physical function. Blood flow restriction (BFR) has been suggested to improve pain and increase muscle strength in healthy subjects and certain diseases. Although there are clinical studies suggesting improvements in knee osteoarthritis symptoms after 4-12 weeks of exercise with BFR, the acute effects of the intervention have not been known. This study aims to assess the effectiveness of low load exercise therapy combined with BFR on acute pain reduction and within 24 hours post-intervention on people with knee OA compared to a placebo group. This study will take place in Athens, Greece, as part of the postgraduate MSc program of the Physiotherapy department of the University of West Attica.
Symptomatic knee osteoarthritis is a serious public health problem in the world, it carries a high personal, social and economic impact. Currently, there are no drugs that modify the natural course of the disease. As analgesic therapy becomes insufficient, more invasive measures are applied, ultimately leading to arthroplasty. The scientific community has joined efforts to develop new therapeutic approaches that allow the delay and regeneration of injured tissue in these patients. These include cell therapy with mesenchymal stem cells derived from different sources. Although most of the clinical studies carried out in different parts of the world with this therapy in patients with knee osteoarthritis have shown therapeutic benefit, it is necessary to develop clinical trials with high quality in our population. The aim of this project is to evaluate the safety, tolerance and efficacy of Cellistem-OA (biological therapy based on mesenchymal stem cells derived from Wharton's jelly of umbilical cord) in patients with knee osteoarthritis in the Colombian population. Investigators proposed to carry out an experimental (clinical trial), randomized, controlled and parallel with 30 participants with knee knee osteoarthritis of the medical complex Fundación Oftalmológica de Santander Clínica Carlos Ardila Lulle. The participants will be randomized into two groups: i) 15 patients who will receive a dose of 2 x 106 Cellistem-OA and ii) 15 patients who will receive an active comparator (acetonide of triamcinolone 10mg / mL), which will be administered by intra-articular injection in the superolateral aspect of the knee. The outcomes to be evaluated will be: (i) decrease in joint pain, (ii) increase in joint functionality, (iii) improvement in quality of life and (iv) improvement of articular cartilage. These parameters will be evaluated at weeks 1, 4, 8, 12, 24, 25, 28, 32, 36 and 52 post-treatments. Additionally, local and systemic adverse events will be recorded to establish whether or not there is an association between them and the intervention.
Osteoarthritis (OA) is a chronic degenerative infection that presents clinical features such as pain and limited range of motion. A weakness of the quadriceps makes this joint more susceptible to wear and tear to the articular cartilage, especially in the medial compartment of the knee. As a result, it is necessary to promote an increase of at least 30% in quadriceps strength for a beneficial effect on pain and 40% in functional capacity. Therapeutic exercises are used to increase strength muscle, in addition to high intensity exercises, to decrease joint pain, low to moderate intensity resistance training has been included, with the new approach of using partial blood flow restriction.
