Filter by:Knee osteoarthritis is the most common type of osteoarthritis in the lower extremity and constitutes 23% of all arthritis cases, about 13% of females and 10% of males aged above 60 years have symptomatic knee OA. Intra-articular corticosteroids (IACs) are a frequently-used treatment regimen for pain relief from symptomatic knee OA as it inhibits inflammation and reduces prostaglandin synthesis. Platelet-rich plasma (PRP) is an autologous blood product containing a high percentage of various growth factors (GFs), such as fibroblast growth factor, epidermal growth factor, vascular endothelial growth factor, transforming growth factor-β and platelet-derived growth factor. The aim of this study is to compare effect of intra-articular injection of platelet rich plasma versus corticosteroid in treatment of primary knee osteoarthritis.
Objective: The aim of this study was to compare the effects of elastic taping, rigid taping, and braces applied to women with mild knee Osteoartritis(OA) on pain, gait, and knee functionality. Methods: This randomised study included 21 female patients (mean age of 53.81±6.20 years) with bilateral grade 2 knee OA according to the Kellgren & Lawrence Classification. Pain was evaluated with the visual analog scale, functionality was evaluated with the Western Ontario McMaster Osteoarthritis Index, and the kinetic, kinematic, and spatiotemporal parameters were evaluated using a three-dimensional gait analysis system at baseline (no application) and immediately after the application of elastic taping, rigid taping, and orthoses. The dependent variables were measured after 45 minute the application of four different conditions neutral, elastic taping, rigid taping, and knee brace on each participant with 1-day intervals.
To compare the efficacy of intraarticular knee injection between leukocyte-rich and leukocyte-poor platelet-rich plasma in knee osteoarthritis treatment
The goal of this clinical trial is to learn about preventing falls in people who have total knee replacement surgery using treadmill perturbation training. Perturbation training involves adjusting to rapid speed changes on a treadmill. The main questions it aims to answer are: - Does perturbation training improve the way that people who are planning to have total knee replacement surgery recover after treadmill test that reproduces a trip to the front or side? - Does perturbation training reduce the incidence of preventable gait-related falls during the first year after total knee replacement? Participants will: - complete surveys about their condition and fall history and take part in testing of walking ability and balance. - have a baseline gait analysis test to measure the motion of their body during normal walking. - Be randomized into two groups. One will receive fall-prevention literature. The other will receive the same literature and then take part in a two-week treadmill perturbation training program. - be contacted every two weeks for one year, and asked questions about whether they have fallen during that time. - wear an activity monitor on their wrist for one week periods, every three months. Researchers will compare the number of falls from the group that received literature to the treatment group to see if the training group has fewer falls during the year after surgery.
To determine if robotically-assisted UKA results in more consistent and improved component positioning and better patient reported outcome scores compared to manual TKA and MAKO TKA.
Diet interventions (e.g., low-energy diets) are recommended as a treatment for obesity, obese patients with osteoarthritis, hypertension (HTN), and type 2 diabetes (T2D). However, these diets are not a common part of the care plan partly because it is not financially feasible to discuss and offer them in medical offices reimbursed with the standard fee-for-service model. New reimbursement models, like value-based care (VBC), exist. It may be financially feasible to offer diet interventions, like premade and delivered meal plans to address these medical issues. This pilot study will help determine if a more extensive prospective study of the clinical effects of a delivered, premade low-energy diet (LED) on clinical markers of these disorders, as well as future cost-benefit analyses. Methods: A case series of five obese subjects with knee osteoarthritis, HTN, and T2D receive a LED for 12 weeks. The primary outcome is the change in the Numeric Pain Rating Scale (NPRS) at 12 weeks. Secondary outcome measures include the change in other patient-reported outcomes between the start and end of the study, changes in weight, changes in measures of HTN and T2D, and the proportion of subjects using non-protocol interventions. Hypothesis: Subjects randomized to the diet intervention will demonstrate a clinically significant improvement in NRPS score (2 points), a clinically significant weight reduction (15%), a 50% improvement in systolic and diastolic blood pressure, 1.0% reduction in Hemoglobin A1C levels (HgA1C), and lower utilization of non-protocol treatments at 12 weeks.
Osteoarthritis (OA) is the most common type of arthritis, characterized by pain and physical disability. More than 10% of persons > 55 years have symptomatic OA, primarily involving the knees. Knee arthroplasty is considered a successful orthopaedic procedure in progressed knee OA (KOA) with severe pain and disability where non-surgical treatments have been tried. It has long been recognized that injury to the body, either from trauma or surgery causes an inflammatory response. As TKA is considered a more invasive procedure compared with UKA, TKA and UKA may not trigger inflammatory reactions of the same magnitude. Differences in inflammatory response between TKA and UKA could help explain why differences in outcome are present, despite both procedures being technically successful. Even though knee arthroplasty is a very common and successful procedure, there are no existing studies comparing the invasiveness of TKA and UKA. As morbidity and mortality rates differ between the groups, the aim of this prospective cohort study is to investigate whether the post-operative inflammatory responses differ between TKA and UKA, and secondarily whether this difference can explain the difference in outcome between the two procedures. The investigators hypothesize that TKA generates a larger postoperative systemic inflammatory response compared with UKA due to more extensive periarticular soft tissue and bone trauma. The study's primary outcome is C-reactive Protein (CRP) measured in blood 24 hours after surgery (22-26 hours after surgery ~ day 1). Participants which are candidates for either a TKA or a UKA will through serial blood test measurement have their postoperative systemic inflammatory response measured. This further will be correlated to the clinical and functional outcomes over a 2-years postoperative follow-up period.
Background: Patient's pain experience is a complex phenomenon. A comprehensive clinical assessment of the patient's pain experience is helpful to define individual differences between patients and thus to plan effective individualized treatment programs. Gait assessment is an important functional task in the clinical evaluation, which allows the definition and modulation of therapeutic intervention. The influence of patient's pain experience on gait parameters is currently understudied in literature. Objective: To investigate patient's pain experience based on an assessment model proposed by Walton and Elliott in patients with knee OA. The study's second aim is to examine the correlation between the parameters of the 10 Meter Walking Test (10MWT) and Time Up and Go test (TUG) assessed by an inertial sensor and the patient's pain experience.
This study aimed to investigate the production of reactive oxygen derivatives (ROS) and reactive nitrogen derivatives (RNT) in female patients with knee OA, and their effects on oxidative stress by evaluating before and after physical therapy in female patients with gonarthrosis who have Kellegren-Lawrence Staging Scale Stage II and III. aimed. To this study; All female cases over the age of 40 who applied to Başkent University Ankara Hospital and were diagnosed with knee OA by a specialist doctor will be included. Method After the cases participating in the study were checked by a specialist physician, the cases that did not prevent them from being included in the study; It will be graded according to the Kellegren-Lawrence Staging Scale. Stage II and III cases will be included in the study. Sociodemographic characteristics of the patients will be recorded before the treatment. 10 sessions of physical therapy program will be applied to the patients. Treatment program 20 minutes Hot pack (HP), 60-100 Hz frequency range, 60 pulse duration and 20 minutes of conventional TENS (Enraf-NoniusBDelftechpark 39, 2600 AV, Delft, The Netherlands) with the patient comfortable feeling and 10 minutes continuous around the knee A home exercise program will be given with ultrasound (Enraf-Nonius-B Delftechpark 39; 1-MHz; 1.5 watts/cm2) to strengthen the muscles around the knees. Those with acute inflammation of the knee joint, those who underwent surgery in the knee joint for any reason or any trauma to the lower extremity, those with a history of uncontrollable high blood pressure, any neurological or vestibular problems, those who have used steroid injections in the last two months, and any For this reason, patients with systemic diseases that will affect the study will be excluded from the study. Staging criteria according to Kellegren-Lawrence Staging Scale; Stage 0: Normal Stage 1: Possible osteophyte Stage 2: Definite osteophyte, suspected narrowing of joint space Stage 3: Moderate osteophyte, definite narrowing Stage 4: Extensive osteophyte, marked narrowing, sclerosis (Kellegren and Lawrence, 1957). Biochemical analyzes: To this study; Blood samples will be taken before and after treatment from a female patient over 40 years old who was diagnosed with knee OA at Başkent University Ankara Hospital. Total antioxidant level (TAS): It will be determined by an automatic measurement method based on the fact that the characteristic color formed by the 2,2'azino-bis (3-ethylbenz-thiazoline-6-sulfonic acid) (ABTS) radical is brightened by the antioxidants in the sample added to the medium (Erel, 2004). Results will be given in mmol Trolox eqivalen/L. Total oxidant level (TOS): will be determined by automatic measurement method (Erel, 2005). The oxidants in the sample have the task of converting the ferrous ion complex to a ferric ion. Ferric ion (Fe3+) formed by oxidation of iron (Fe2+) to its more stable form (Fe2O3) creates color with xylenol orange in acidic environment. The intensity of the color measured spectrophotometrically is related to the total amount of oxidant molecules present in the sample. The measurement is calibrated with hydrogen peroxide (H2O2) and the results will be given as micromolar H2O2 equivalent per liter (µmol H2O2 equiv./L) (Sydow, 1985). Nitric oxide (NO): Serum nitric oxide concentration (Mirand et al, 2001) will be measured in a spectrophotometer according to the method (PowerWawe XS, BioTek, USA). Serum samples will be deproteinized with 10% zinc sulfate. In this method, nitrate was converted to nitrite with Vanadium (III) chloride. It is based on the measurement of the complex diazonium compound as a result of the reaction of nitrite and sulfanilamide N-(1-Naphthy) ethylene diamine dihydrochloride in an acidic medium. High-density lipoprotein (HDL): It will be run in an autoanalyzer using the Biotrol trademark kit and given in mg/dl. The results will be recorded for each individual on the information sheet.
The goal of this clinical trial is to compare a pain informed movement program to standard neuromuscular exercise in people with knee osteoarthritis. The main question it aims to answer are: 1. Are the two interventions a) pain informed movement program plus pain neuroscience education and b) neuromuscular exercise plus standard osteoarthritis education feasible in terms of recruitment, treatment adherence, timelines, data collection procedures, patient follow-up, and resources required? 2. Is there a difference in patient's satisfaction and acceptability of the two programs? 3. Are there any differences in the potential effects of the two programs on subjective pain measures, self-reported function, quality of life, functional leg strength, nervous system pain modulation, brain derived neurotrophic factor and nerve growth factor levels, and psychological factors?
