Active clinical trials for "Osteoarthritis, Knee"

To study synovial membrane (SM) inflammation in suprapatellar fossa in advanced knee osteoarthritis (OA), and to correlate the pathological features with clinical findings.

Retrospective collection of data, aimed at a better knowledge of the context of use of Synvisc® among the patients practising a regular activity (professional/leisure), and at evaluating the different practices and their results.

The primary objective of this study is to identify osteoarthritis (OA) structural changes, as assessed by MRI, that best correlate with the presence of neuropathic pain (NP) using the PainDETECT questionnaire (PainDETECT ≥ 13) on a population of patients with OA of the knee experiencing moderate to severe pain (VAS ≥ 40 mm).

The purpose of this study is to evaluate the costs and benefits of the ConforMIS iTotal® total knee replacement system versus standard total knee arthroplasty. This study is designed to illustrate the difference in cost between standard total knee replacements and the ConforMIS iTotal at a single institution.

The purpose of the study is to acquire kinematic in vivo fluoroscopy data from subjects who were implanted with the Smith & Nephew Journey II posterior cruciate retaining (PCR) total knee arthroplasty (TKA) or Journey II bi-cruciate retaining (BCR) TKA. CMR has previously collected data for the Smith & Nephew BCS TKA and compared these kinematics data to those of normal knees.

Evaluation and comparison of histological analysis, 9,4 tesla MRI, Full-Field Optical Coherence Tomography (FFOCT) and ultrasound-based navigation system for cartilage degeneration analysis of patellofemoral joint.

Based on the research background and the preliminary research basis of the research group, in order to answer the material basis and micro-physical environment change characteristics of knee osteoarthritis sensitization acupoints and provide scientific basis for in-depth study of sensitization of acupoints. This study plans to use knee osteoarthritis as a research vehicle, and use microdialysis combined with high performance liquid chromatography to analyze the local material basis and key indicators of common sensitization points in knee osteoarthritis.

This study will investigate the concurrent validity and intra-rater reliability of using smartphone in assessing joint position sense in patient with knee osteoarthritis.

Patients with osteoarthritis of the knee undergo visible joint changes in radiology and Magnetic resonance imaging (MRI) tests, but also clinically and histologically. The area of greatest change is at the subchondral/cartilage bone junction. Investigators will determine the association between preoperative clinical evaluation (IKDC and Womac scores), radiological classifications and histopathology. In addition, the role of inflammation in the pathogenesis of osteoarthritis is being given major interest, and inflammation is closely linked with vascularization. It was recently demonstrated that dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) could identify the subchondral bone marrow vascularization changes occurring in osteoarthritis in animals. These changes appeared before cartilage lesions were visible and were correlated with osteoarthritis severity. Thus the opportunity to obtain an objective assessment of bone vascularization in non-invasive conditions in humans might help better understanding osteoarthritis pathophysiology and finding new biomarkers. Investigators hypothesized that, as in animals, DCE-MRI has the ability to identify subchondral bone marrow vascularization changes in human osteoarthritis.

This study sought to better identify the motivators and barriers to osteoarthritic patients practising regular physical activity. This is a crucial step towards enabling each health professional to adapt their therapy recommendations, while taking into account the patient's overall lifestyle.
