Active clinical trials for "Osteoarthritis, Knee"

Geniculate Artery Embolization (GAE) has recently been described and studied as a palliative treatment for osteoarthrosis-related knee pain in patients un-eligible for surgical intervention. This treatment is based on the hypothesis that hypervascularization and associated increased nerve proliferation are possible sources of chronic pain following the morphological changes of osteoarthrosis. A large animal model has shown digital subtraction arteriography to be well correlated to both the histological findings of synovial inflammation and synovial contrast enhancement on magnetic resonance imaging. This embolization technique has also been applied to other regions of the musculoskeletal system including the elbow and the shoulder.

The investigators will be comparing the efficacy of two different techniques for performing an adductor canal block to the saphenous nerve as a part of the multimodal pain control regimen for total knee arthroplasty. The investigators will be comparing a "low adductor canal block" in which the surgeon administers local anesthetic to the distal aspect of the nerve from the operative site to a "high adductor canal block" in which the anesthesiologist administers the local anesthetic more proximally along the thigh using ultrasound guidance. The investigators will power the study for non-inferiority to compare the newer "low" block to the more commonly performed and more widely studied "high" block.

In terms of the surgical treatment of the cartilage injury, various techniques and ways are created to repair or regenerate articular surface of synovial joint following traumatic damage or degeneration of the cartilage. The option for surgical treatments based on the size and depth of the cartilage knee injury may include knee debridement, radiofrequency, drilling, microfracture, mosaicplasty, allogenic osteochondral transplantation and autologous chondrocyte transplantation. The first two techniques mentioned have been used in treating the cartilage knee injury involving the partial defects meanwhile the latter techniques have been used for Grade III and IV cartilage defects based on ICRS. However, most of the surgical options up only provide more of Type I collagen rather than Type II collagen. The available treatments are more symptomatic rather than preventive or regenerative. Stem cell has big potential in this area where it has ability to differentiate to cartilage. As allogeneic umbilical cord blood MSCs are readily available and can be administered immediately, this study therefore aims to prove the efficacy of allogeneic umbilical cord-derived mesenchymal stem cells (UC-MSCs) for treating large defects knee injury. The study is a prospective, randomized controlled, open label, phase IIb clinical trial, involving 50 patients with large defects of cartilage injury for follow-up duration of 24 months. Patients will be assigned into 2 arms; Arm A - 25 subjects will receive Chondrocell-EX (UC-MSCs) and Arm B - 25 subject will receive marrow cellution. All patients will undergo debridement prior to receiving their assigned treatment. The patients will be assessed on KOOS, IKDC, VAS and MRI.

Disabling symptoms of osteoarthritis are seen in approximatively 10% of people over 55 years old. Many patients suffer from persistent pain symptoms from moderate osteoarthritis despite optimal medical treatment. For these patients, several minimally-invasive surgical treatments have been proposed, including arthroscopic lavage and debridement; however, none of these treatments have been proven effective compared to sham treatment. Recently, catheter-directed embolotherapy of the geniculate arteries has been propagated as a real alternative to medical management in patients with mild to moderate knee osteoarthritis unresponsive to conservative medical management.

Articular cartilage degradation is the main characteristic of osteoarthritis (OA), involving enzymatic and inflammatory mechanisms that change it into a chronic disease. Since articular cartilage shows limited regenerative ability, several intra-articular drugs have been developed in order to decrease inflammation and provide a better clinical outcome to the patient.

The purpose of this study is to explore the efficacy and safety of autologous adipose mesenchymal stem cells in the treatment of early knee arthritis. Investigator believes that autologous adipose mesenchymal stem cells can relieve pain, improve knee function, promote knee cartilage regeneration and improve life satisfaction of patients.

This study was aimed to evaluate the efficacy and safety of Autologous Adipose-derived Mesenchymal Stem Cell Gel combine with High tibial osteotomy therapy in the treatment of cartilage damage in the knee. Investigator believe that this method will enable patients to recover better knee function and more repair of knee cartilage.

This is a randomized controlled trial comparing the short-term effect of electromoxibustion and knee health education for relieving knee pain in older adults with knee osteoarthritis.

This is a proof-of-concept study to determine the safety and efficacy of a novel device to increase the reparative capacity of the knee. The discovery of a resident population of mesenchymal stem cells (MSCs) within synovial fluid (SF) was the first description of this reparative cell population having direct access to superficial cartilage and joint structures. The ready access of SF MSC to cartilage and other joint tissues offers a novel strategy for joint repair. Current arthroscopic procedures result in the removal of all SF MSCs due to continuous irrigation throughout the procedure. The current study would benefit the patient by greatly increasing the reparative capacity of the joint by bolstering MSC numbers and retaining those MSCs within the joint after surgery. By accessing MSCs from the synovium it is anticipated that these cells would be entrapped/migrate into the marrow clot formed by microfracture of the sub-chondral bone. These MSCs would supplement those from the marrow and may result in faster, better quality repair.

The purpose of this study is to compare the effect of post-operative ROM between Flex IM rod and Rigid IM rod, to collect bone morphology of Japanese lower extremity and to research the incidence of overhung with Flex IM rod.
