Osteoarthritic Knee Pain

The overall goal of this project is to establish a novel design and control paradigm for modular, partial-assist powered orthoses (exoskeletons) to enhance voluntary lower-limb motion and manage pain in broad patient populations. Building upon a previous study period that addressed weakness from advanced age or muscle fatigue, this current period extends the technology to novel powered unloader orthoses designed to manage knee osteoarthritis (OA) pain. The investigators hypothesize that by providing 15-30% of biological joint torque, these motorized devices can reduce muscular contributions to painful loads on the joint's surfaces during activities of daily living (ADLs). The project aims to develop a task-agnostic, neural network-based controller and establish the feasibility of reducing knee pain and muscle effort in individuals with multi-compartment knee osteoarthritis.

The goal of this clinical trial is to learn if GNSC-001 works to treat knee osteoarthritis in adults. It will also learn about the safety of GNSC-001. The main questions it aims to answer are: 1. Does GNSC-001 lower daily knee joint pain and improve function in participants? 2. What medical problems do participants have when taking GNSC-001? Researchers will compare GNSC-001 to a placebo (a look-alike substance that contains no drug) to see if GNSC-001 works to treat knee osteoarthritis. Participants will: 1. Receive a single injection of immune-modulation, and GNSC-001 or a placebo, in their knee 2. Take an oral immune-modulating pill every day for the first 22 days 3. Visit the clinic at least 9 times over 2 years for checkups and tests 4. Keep a diary of their symptoms and the number of times they use a rescue medication

The primary purpose of this study is to find out if there is a difference in pain experienced in patients with knee arthritis of the inside of their knee if they get a steroid injection on the inside or outside of their knee. Participants will: 1. Be randomly divided into getting their steroid injection on the inside or outside of their knee. 2. Answer a pain survey before their injection as well as over the phone 2 weeks, 6 weeks, and 12 weeks after their injection.

This clinical study investigates a minimally invasive treatment called percutaneous transcatheter embolization of knee arteries for patients with chronic knee pain caused by advanced knee osteoarthritis or persistent pain after total knee replacement. Osteoarthritis of the knee is a common degenerative condition that can lead to long-term pain, reduced mobility, and decreased quality of life, and some patients do not achieve sufficient relief with standard treatments. The study is based on the hypothesis that targeted embolization of small arteries supplying the inflamed tissues of the knee can safely reduce abnormal blood flow associated with inflammation, leading to pain relief and improved knee function. During the procedure, a thin catheter is guided through the blood vessels to the affected area of the knee, where a temporary embolic agent is administered to reduce pathological blood supply. The aim of the study is to evaluate the safety and effectiveness of this procedure by assessing changes in pain intensity, knee function, and quality of life over a follow-up period of up to 24 months. The results of this study may help determine whether this minimally invasive approach can offer a new treatment option for patients who have limited alternatives for managing chronic knee pain

To demonstrate the potential benefits and risk of active sub-threshold stimulation in the treatment of chronic knee pain as compared to subjects that did not have active stimulation. Improvement will be assessed in relation to the clinical outcome measures of pain, with primary endpoint; Pain relief rate as measured by the number of subjects with greater or equal to a 50% decrease in pain on the visual analog scale, comparing baseline to the 1-month follow-up.
