Active clinical trials for "Osteoarthritis, Knee"

Through research and analysis, the levels of upstream and downstream factors related to TGF-β/Smad signaling pathway and inflammatory response factor related factors in serum, blood cells, articular fluid, urine, tongue covering and discarded tissues after surgery of patients with LKD syndrome and PBS syndrome of knee osteoarthritis were obtained, and the syndrome characteristics were further obtained. Through research and analysis, the index levels of multiple omics detection in serum, blood cells, joint fluid, urine, tongue coating and discarded tissues of patients with LKD syndrome and PBS syndrome of knee osteoarthritis were obtained, and the syndrome characteristics were further obtained. The severity of syndrome was quantified by syndrome score scale and the correlation between the above results and the syndrome score of patients with knee osteoarthritis with LKD syndrome and PBS syndrome was studied in combination with imaging characteristics. To establish a "disease and syndrome cell model" and test relevant indicators to support the above research. Through the analysis of the above research results, the possible mechanism is analyzed to provide an objective basis for the biological basis of the syndrome and relevant evidence for the clinical diagnosis and treatment of knee osteoarthritis with traditional Chinese medicine.

This study aims to investigate the effectiveness and safety of human umbilical cord mesenchymal stem cell injection in the articular cavity to treat moderate to severe knee osteoarthritis (OA), and whether it can achieve articular cartilage regeneration, reduction of joint pain, and restoration of joint function.

This study will examine the pain-relief efficacy and safety of L-arginine in knee OA patients.

The purpose of this study is to evaluate the efficacy of an intravenous (IV) perioperative dexamethasone regime in the clinical outcomes after a robotic-assisted Total Knee Arthroplasty (TKA) in a Hispanic population. The study aims to propose an alternative to opioid-based pain treatment following TKA. The study hopefully validates the use of a two-dose, 8mg intravenous dexamethasone regimen for improving pain and range of motion scores in patients undergoing primary, unilateral TKA for osteoarthritis. One dose will be applied prior to incision and the other at post-operative day (POD) 1.

The goal of this cross-sectional study is to evaluate muscle architecture changes and it's effect on muscle strength in female patients with gonarthrosis.Main questions are: Is there any correlation between muscle strength and muscle thickness, pennation angle fiber length? Is there any muscle architecture difference in gonarthrosis and is it effecting the muscle strength? The investigators will enroll patients with unilateral gonarthrosis so that investigators can compare the changes within osteoarthritic and healthy knee with the same physical activity levels.

This study will establish a machine-learning algorithm to predict KAM using IMU sensors during stair ascent and descent; and then conduct a three-arm randomized controlled trial to compare the biomechanical and clinical difference between patients receiving a course of conventional laboratory-based stair retraining, sensor-based stair retraining, and walking exercise control (i.e., walking exercise without gait retraining). The investigators hypothesise that the wearable IMUs will accurately predict KAM during stair negotiation using machine-learning algorithm, with at least 80% measurement agreement with conventional calculation of KAM. The investigators also hypothesise that patients randomized to the laboratory-based and sensor-based stair retraining conditions would evidence similar (i.e., weak and non-significant differences) reduction in KAM (primary outcome) and an improvement of symptoms (secondary outcomes), but that these subjects would evidence larger reductions in KAM than subjects assigned to the walking exercise control condition.

Obesity and other associated complications promote the development and the progression of osteoarthritis. The subcutaneous and abdominal fat release several factors that alter bone and the cartilage. The role of the marrow fat in close connection with bone has not been defined yet, whereas cellular and animal models indicate that this fat depot modifies bone and cartilage. The aim of the study is to define if the marrow fat produces more joint-altering factors by comparison with subcutaneous fat. This fat depot can be characterized from removed pieces during the prosthetic surgery of the knee. Measuring before surgery the body weight, waist and hip circumferences, blood pressure, glucose, insulin and lipids in blood will also allow to determine if obesity and/or type 2 diabetes make this fat more dangerous for the joint. Such research will allow the elaboration of new therapeutic strategies in osteoarthritis.

To evaluate the efficacy and safety of different doses of triamcinolone for local infiltration analgesia during total knee replacement

The goal of this study is to learn about the effect of video-game based rehabilitation exercise for patients with knee osteoarthritis. The main question the study aims to answer is: do patients who exercise with the game have better functional outcomes and engagement compared to patients who do conventional exercise? Participants will complete 10 weeks of physical therapy exercise sessions that focus on quadriceps strengthening. Two sessions per week will be conducted in the clinic, and one session will be conducted at home each week. The interventional group will conduct all exercises using the KneeBRIGHT EMG sensors and game software. The control group will conduct all exercises following a standard physical therapy regimen. Researchers will compare knee function and engagement between the group who uses the game, and the group who does conventional exercise.

A randomised controlled triall (RCT) with three parallel arms comparing the functional outcome of chemical ablation with phenol and radiofrequency ablation (RFA) of the genicular nerves with conservative treatment in patients with chronic knee pain caused by osteoarthritis (OA).
