Filter by:This phase I/II study aims to evaluate the safety of single doses of 2ccPA 4,800 μg and 7,200 μg (Phase I), as well as the safety and efficacy of multiple doses of 2ccPA (Phase II) in patients with osteoarthritis (OA) of the knee.
The Aim Is To Study The Anatomic Relationship Of The Popliteal Vesseles In Two Types Of (OWHTO) Techniques (Monoplanar VS Biplanar) Which Provide More Safe Technique To The PV
Osteoarthritis of the knee is a common problem that is increasing in prevalence as the population ages. In a knee with osteoarthritis, there is variable damage to the articular cartilage and underlying bone that can cause varying degrees of pain. When pain is bothersome, osteoarthritis is treated to improve functional abilities. One of the most recognized and used treatments is intra-articular cortisone injection. Cortisone is a powerful anti-inflammatory drug that is used to reduce pain. Unfortunately, cortisone can have significant side effects, even when injected locally. The frequency and intensity of these side effects depend largely on the total dose injected. The main side effects include increased blood sugar levels, increased blood pressure and a temporary decrease in the secretion of the stress hormone, cortisol. In the long term, a decrease in articular cartilage thickness in the injected join and overall bone density reduction is also reported. Despite many years of routine use, the smallest effective dose of cortisone injected into the knee joint is unknown. The main objective of the study is to determine the impact on pain and function of different doses of cortisone injected into the knee. The cortisone chosen for this study is triamcinolone acetonide (TA).
The primary aim will seek to understand whether Cognitive Muscular Therapy (CMT) could provide pain relief for people on a waiting list for joint replacement.
Osteoarthritis (OA) is the most common joint disease, causing severe pain due to joint inflammation (synovitis). While total knee arthroplasty (TKA) is commonly performed to reduce pain, 20% of patients are dissatisfied with their outcome post-surgery. This dissatisfaction is caused by persistent pain post-TKA due to synovitis that is not routinely removed during surgery. To address this problem, a synovectomy can be performed during TKA, which involves resecting the inflamed layer of tissue lining the joint, called the synovium, and its associated sensory nerve endings. Since the synovium will regenerate in the months post-surgery, synovectomy only transiently reduces pain after TKA. The proposed study will help ascertain the benefits and effects of synovectomy in patients who are more likely to experience poor satisfaction (driven mostly by pain) post-TKA. This study will include 62 patients undergoing TKA due to end-stage OA who have moderate to severe synovitis, as determined by ultrasound assessment. Patients will be randomized (1:1) to undergo a TKA with synovectomy or without synovectomy. Primary and secondary outcomes will be assessed through patient-reported levels of pain and function, results from physical performance tests, and quality of life (QOL) scores. These measures will be recorded pre- and post-surgery for comparison. Through demonstrating that synovectomy can at least transiently reduce pain post-TKA, this study will provide evidence for the development of medical therapies that target the synovium to slow its regrowth. This will be transformative for the long-term management of joint pain and synovitis post-surgery, thus significantly improving patients' overall QOL.
The purpose of this study is to determine the safety and efficacy of the 40 mg and 100 mg doses of allogeneic micronized dehydrated human amnion/chorion membrane (micronized DHACM) injectable compared to 0.9% sodium chloride injection, placebo control for the treatment of knee osteoarthritis
The ForceLoss study aims to develop personalised modeling and simulation procedures to enable the differential diagnosis for the loss of muscle force, namely dynapenia. The primary causes of dynapenia can be identified in a diffuse or selective sarcopenia, a lack of activation (inhibition), or suboptimal motor control. Each of these causes requires different interventions, but a reliable differential diagnosis is currently impossible. While biomedical instruments and tools can provide valuable information, it is often left to the experience of the single clinican to integrate such information into a complete diagnostic picture. An accurate diagnosis for dynapenia is important for a number of pathologies, including neurological diseases, age-related frailty, diabetes, and orthopaedic conditions. The hypothesis is that the use of mechanistic, subject-specific models (digital twins) to simulate a maximal isometric knee extension task, informed by experimental measures may be employed to conduct a robust differential diagnosis for dynapenia. In this study, on patients candidate for knee arthroplasty, the investigators will expand (i) the experimental protocol previously developed and tested on healthy volunteers with a measure of involuntary muscle contraction (superimposed neuromuscular electrical stimulation, SNMES), a hand-grip test, measures of bio-impedance and clinical questionnaires, and (ii) the modeling and simulation framework to include one additional step (to check for muscle inhibition). Medical imaging, electromyography (EMG) and dynamometry data will be collected and combined to inform a digital twin of each participant. Biomechanical computer simulations of a Maximal Voluntary Isometric Contraction (MVIC) task will then be performed. Comparing the models' estimates to in vivo dynamometry measurements and EMG data, the investigators will test one by one the three possible causes of dynapenia, and, through a process of hypothesis falsification will exclude those that do not explain the observed loss of muscle force.
The hypothesis is that the use of spa therapy in Saint-Lary Soulan for knee osteoarthritis treatment would have a therapeutic effect on this pathology. The main objective of this external comparison study is to evaluate the comparative effectiveness at 6 months of spa therapy in the Saint-Lary Soulan spa center on functional disability and pain (MCII: Minimal Clinical Important Improvement) in knee osteoarthritis compared to the control group of the Thermarthrose multicenter randomized clinical trial, receiving standard cares. The patients included in the Larytherm cohort will undergo a three-week spa therapy in Saint-Lary Soulan with a follow-up of 6 months after the end of spa therapy.
A phase 1 exploratory clinical study to investigate safety, tolerance and efficacy of a single intra-articular injection of autoSTEM-OA or alloSTEM-OA in participants with mild to moderate knee osteoarthritis
The goal of this clinical trial is to compare function in reverse shoulder arthroplasty (RSA) using two different degrees of humeral retroversion (RV). The main question it aims to answer is: • Does external rotation improves when using a higher retroversion? Participants will randomly receive a 0 degree or 30 degree RV for their RSA. They will be followed for two years and clinical outcomes will be recorded and analyzed.
