Filter by:The goal of this clinical trial is to compare FSN with oral Nonsteroidal Antiinflammatory Drugs (NSAIDs) in pain relief and improvement in knee function among elder people, the main questions it aims to answer are: Q1: Compared with the positive drug (celecoxib), whether FSN is more or at least as effective for pain relief and improvement in knee function in elder people with knee arthritis. Q2: From the biomechanical point of view, what is the mechanism by which FSN plays a therapeutic role in knee osteoarthritis (KOA)? Participants will: 1. Will be randomly assigned to 2 groups. There will be 30 participants in each group. 2. A group of patients will receive FSN monotherapy, while the other group will receive oral celecoxib and pantoprazole. Each patient will receive a 2-week course of treatment. 3. Visual analogue scale (VAS), WOMAC, knee range of motion (ROM), gait analysis, and musculoskeletal ultrasonography (US) of lower extremity muscles will be assessed during treatment and in the follow-up. Researchers will compare FSN and celecoxib to see if FSN has better, or at least equivalent, efficacy than celecoxib, which is commonly used in clinical practice.
Background: The aim of this study was to compare the knee and ankle muscle architecture and plantar pressure distribution differences in knee osteoarthritis (OA) women with healthy women. Methods: Fifty women with knee OA (Mean age=52.11±4.96 years, mean BMI=30.94±4.23 kg/m2) and fifty healthy women (Mean age= 50.93±3.78 years, mean BMI=29.06±4.82 kg/m2) were included in the study. Ultrasonography was used to evaluate Rectus Femoris (RF), Vastus Medialis (VM), Vastus Lateralis (VL), Peroneus Longus (PL), Tibialis Anterior (TA), and Medial Gastrocnemius (MG) muscle thickness, pennation angle, fascicle length, and fat thickness. The plantar pressure distribution was evaluated using the Digital Biometry Scanning System and software (DIASU, Italy).
1. Prevalence of osteoarthritis in France Osteoarthritis (OA) is a very common disease, affecting almost 15% of the population. It is responsible for a significant socio-economic cost in connection with the chronic and disabling pain it causes . Gonarthrosis is the most frequently encountered arthritic localization . In a large 2010 meta-analysis, the main risk factors for developing knee OA were shown to be obesity, previous knee trauma, hand OA, female gender and advanced age. Smoking appeared to have a moderate protective effect . The risk of developing gonarthrosis in obese patients is 2.6 times higher than in the general population. Hypercholesterolemia itself is a risk factor for osteoarthritis, as are increased plasma levels of specific fatty acids and lipoproteins Inflammatory mechanism in osteoarthritis. Studies have shown that plasma levels of C-reactive protein, can be used to estimate individual susceptibility to developing osteoarthritis over a lifetime . In osteoarthritis patients, plasma concentrations of TNF-α, IL-6 and IL-1 are abnormally high, which appears to contribute to cartilage loss in these subjects . 3. Inflammatory mechanism in obesity. Obesity induces systemic and local joint mechanical stresses that increase the risk of developing gonarthrosis in obese or overweight individuals . Beyond the simple mechanical aspect, a body of evidence supports the assertion that obesity is responsible for a systemic inflammatory state, deleterious to joints. 1) Obesity is associated with radiographic and symptomatic osteoarthritis in non-weight-bearing joints, such as the hand In overweight and obese adults, plasma levels of tumor necrosis factor alpha (TNF-α) and interleukin-6 (IL-6) are significantly increased . 3)Weight loss in obese subjects with osteoarthritis alleviates joint symptoms through reduced mechanical stress but also through reduced production and response of inflammatory products . 4. Common inflammatory mechanisms between adipose tissue and obesity. The relationship between adipose tissue and inflammation is complex given the different types of adipose tissue and the action of cells derived from it. Adipose tissue is an active endocrine organ composed of mature and developing adipocytes, as well as fibroblasts, endothelial cells and a wide range of immune cells, namely adipose tissue macrophages, neutrophils, eosinophils, mast cells, T cells and B cells. Adipose tissue is recognized as an endocrine organ that secretes a large number of inflammatory mediators, including cytokines (IL-1, IL-6, IL-8, TNF-α) and adipokines (leptin, adiponectin, resistin, visfatin). Communication between adipocytes and immune cells maintains tissue homeostasis. Obesity, however, can upset this balance. Lipid metabolism and joint disorders have been shown to be linked . A high-fat diet may contribute to the development of osteoarthritis . White and brown adipose tissue appear to play a complementary role in the development of osteoarthritis. Increased white adipose tissue in obesity is thought to create a systemic environment of increased inflammation through the release of pro-inflammatory cytokines and adipokines such as leptin and visfatin, all of which have been associated with osteoarthritis . Locally, white adipocytes in infra patellar adipose tissue are architecturally different in patients without gonarthrosis compared with those with knee osteoarthritis. This difference suggests that adipocyte gene expression is directly influenced by inflammation . In obese individuals, there is elevated IL-6 production in brown adipose tissue . Furthermore, it would appear that brown adipose tissue, unlike white, down-regulates the inflammatory profile of macrophages .
The goal of this pilot randomized clinical trial is to look into the efficacy of concentrated bone marrow aspirate (cBMA) in improving post traumatic osteoarthritis (PTOA) symptoms in patients undergoing revision anterior cruciate ligament reconstruction surgery. The main questions it aims to answer are whether clinical outcomes, such as pain, are improved in patients who get cBMA with surgery, if there is a change in circulating markers of inflammation and what part of the cellular and molecular composition of cBMA may explain its effects.
REAL INTELLIGENCE™ CORI™ (CORI Surgical System) is a computer-assisted orthopedic surgical system. CORI Surgical System is designed to aid surgeons in planning and executing a procedure involving bone preparation for total knee arthroplasty (TKA) procedures. CORI Surgical System is comprised of a console control unit, optical tracking camera, primary and secondary input displays (tablet and optional display monitor), and foot pedal. The CORI Surgical System software consists of a patient and user management module, a surgical planner, and an intra-operative cutting module. Yuanhua Orthopaedic Robotic Systems, KUNWU, is an open-platform robotic system that does not restrict surgeons in choosing the type of prosthesis implant. It is the only Orthopaedic Robotic System in Hong Kong registered with the HK Department of Health Medical Devices Control Office (MDCO) as an open platform system. Unlike other manufacturer's implant-based robots (closed systems), Yuanhua's objective is to provide maximum flexibility in choosing the best implant for each patient. Closed system robots not only impact the surgeon's choice of implant for an individual patient but also affect the hospital's implant purchases over multiple years without any negotiation power on pricing. This business model is often referred to as a "razor and razor blade" model. The primary objective of this study is to evaluate the use of open and closed platform robotic-assisted TKA procedure in achieving post-operative leg alignment as compared to procedures using standard instruments. The secondary objective of this study is to assess the safety and performance of the robotic-assisted TKA procedure up to 12 months after surgery as compared to procedures using conventional manual instruments.

The purpose of this study will be to compare the combined effect of using Kinesio taping versus interferential current with an exercise program on knee pain, function, knee range of motion, knee muscle strength, and functional mobility in chronic knee osteoarthritis.
The goal of this prospective study is to compare two different knee replacement robots. This study will look at patient reported outcome measures and data collected during the operation. The main questions this study aims to answer include: - Will the patient reported outcomes differ between the two groups? - Will the intraoperative data differ between the two groups? Participants will undergo total knee replacement with one of the two robots, complete standardized surveys, and have x-rays taken.
The goal of this clinical trial is to assess the effectiveness of dietary supplement combined with exercise in managing knee osteoarthritis (KOA). The main questions it aims to answer are: - Is adding a dietary supplement to exercise additionally effective in managing KOA? - Is adding exercise to the dietary supplement additionally effective in managing KOA? Participants will be given in three groups: 1. Real dietary supplement alone 2. Real dietary supplement with exercise 3. Placebo dietary supplement with exercise Investigators will compare groups 1 and 2, or 2 and 3, to answer the research questions. The hypothesis is that participants who receive the dietary supplement along with exercise will experience greater reduction in pain level, improved physical function, and enhanced quality of life compared to those who receive a placebo combined with exercise or dietary supplement alone.
The goal of this interventional pilot study is to evaluate if performing ligament balancing on the medial collateral ligament (MCL) in a more systematical manner with a novel instrument can produce more objective and repeatable ligament lengthening in Total Knee Arthroplasty. The main questions it aim to answer are: 1. Is it feasible to perform systematic ligament balancing on the MCL using a novel instrument? 2. Can a novel instrument for ligament balancing acquire more objective and repeatable results, without risk of injury? Participants must consent prior to the surgery, but inclusion is only done once ligament balancing is indicated during surgery. Patients will be follow-up as standard protocol for Total Knee Arthroplasty patients at the hospital.
