Active clinical trials for "Osteoarthritis, Knee"

The primary objectives of the survey are to obtain patient preference information that can be useful during the benefit-risk assessment of the KineSpring System.

The goal of this observational study is to learn about the association between pain characteristics and cognitive functions in chronic knee osteoarthritis. The main questions it aims to answer are: If pain characteristics affect cognitive functions in severe knee OA patients? If concentration of neuroinflammation mediators were raised in severe knee OA patients with comparing with control group participants? Participants will receive pain and cognition questionnaire before surgery and their blood and CSF will be collected for further analysis of neuroinflammation mediators.

The purpose of this study is to determine the construct validity of the Canary Tibial Extension's measure of self-selected community walking speed. Construct validity will be assessed by the Pearson's correlation coefficient between self-selected community walking speed and the 4-meter walk test. The objective of this multicenter, prospective study is to demonstrate that remote measurement of community walking speed with the Canary canturioTM (CTE) tibial extension is correlated with the fast 4-meter walk test (4mWT).

Techniques used to restore the physical functions in TKR patients

This is a descriptive cross-sectional study conducted to evaluate the nutritional status and total antioxidant/oxidant capacity of individuals diagnosed with osteoarthritis.

New anticoagulants are being introduced to replace warfarin. These drugs do not require monitoring and are safer. There is currently no recommended way to reverse these drugs rapidly in the event of undue bleeding or need for emergency surgery. This is a lab study to look at ways to reverse the drugs rapidly

Articular cartilage can be the seat of many diseases including osteoarthritis and traumatic defaults. The cartilage has no intrinsic ability to repair resulting at long term in function loss in the joints. Currently available treatments are not satisfactory in the long term, the use of mesenchymal stem cells appears to be promising due to their ability to multipotency and immunomodulation properties. This project aims to determine the most appropriate source for regenerative medicine of cartilage stem cells from tissue taken during arthroplasty in patients with osteoarthritis. These cells will be tested for different chondrogenic markers. The success of this project will consider the implementation of a strategy for regenerative medicine in bone and joint diseases.

This proposal outlines the investigators plan to develop, evaluate and implement an accelerated in hospital and community rehabilitation following total knee arthroplasty (TKA) leading to outpatient TKA. The benefits of applying current concepts of improved postoperative analgesia and less invasive surgical technique are expected to improve objective parameters of knee function, increase patients satisfaction, while reducing health care resources requirements as compared with standard rehabilitation. The innovation of combining best practices from orthopaedic sports medicine, Anesthesia, Physiotherapy and Knee reconstruction are expected to realize this goal.

Objective: To assess the impact of intraarticular hyaluronic acid (HA) on clinical outcome and on volumetric and T2 relaxation based changes of articular cartilage in mild to moderate osteoarthritis (OA) of the knee joint. Methods: Patients with moderate OA of the knee [Kellgren-Lawrence II] were recruited for a 6-months prospective, randomized clinical trial evaluating the effect of HA on articular cartilage morphology and composition. Clinical examinations and MRI were performed at baseline, and after 6, 12 and 24 weeks. Cartilage volume, thickness and surface area were determined in cartilage plates and subregions were defined using proprietary software. MRI was performed on a 1.5 Tesla scanner; morphological evaluation was performed using 3D T1-w FLASH Waterexcitation (WE) sequences and T2 maps were calculated from a multiecho, spin-echo sequence.

Medial compartment osteoarthritis of the knee is commonly treated by a surgical intervention called 'high tibial osteotomy' (VTO). Although it has repeatedly been shown that pain improves following this procedure, it is unknown how cartilage quality is affected by the procedure. In this study, a recently developed MRI technique is used to evaluate changes in cartilage quality before and after the surgery. Changes in MRI signals are correlated to subjective improvements (score lists). 10 patients participate in this study. Approval has been granted by the Medical Ethical Committee of the University Medical Center Utrecht. All participants are required to give informed consent before participation.
