Filter by:Although knee pain is prevalent among community-dwelling older adults, little is known about how people in general handle their pain. We will conduct a survey to explore how knee pain affects people's lives and which treatments or self-management strategies they have chosen (or are being offered), and how these interact concerning pain reduction and maintenance of function.
Predictive factors of osteoarthritis progression are not yet well understood. However, a growing role attaches importance to the subchondral bone. The aim of the present project is to determine predictive factors of progression of osteoarthritis at the knee by a multimodal characterization of subchondral bone by Medical Resonnance Imaging, direct high resolution digitization radiographs and bone texture analysis. At the end of the project, an innovative imaging device, combining semi-automatic softwares for texture analysis, control detection and image registration would be supplied. This will enable on the one hand a more accurate and reproducible way to measure the joint space width of the affected compartment and on the other hand, an assistance to better detect patients at risk of progression of their knee osteoarthritis. Identifying These "progressors" patients might permit their selection in clinical trials at baseline adapted to their severe disease, using for example biologic treatments targeting knee osteoarthritis. The main objective of this study is to analyze the predictive capacities of bone texture parameters measured on the high-resolution radiography of the knee on the structural evolution of the knee osteoarthritis at 3 years.
This is a randomized study comparing the measured resection and gap-balancing surgical techniques for total knee replacement (TKR) using a cemented Journey II TKR implant system. We will be comparing the two surgical methods by evaluating implant migration using radiostereometric analysis (RSA) imaging, evaluating contact kinematics (knee mechanics) through RSA under dynamic conditions and comparing patient knee outcome scores.
This is a prospective, multi-center study, designed to assess mid-term performance of the MOTO Medial® Unicompartmental Knee Arthroplasty (UKA), with patient report outcomes, clinical findings and radiographic analysis.
This study was designed to demonstrate the safety and performance of the JOURNEY II XR total knee system by evaluating implant survival rates at 10 years using Kaplan-Meier analysis. All participants will be implanted with the JOURNEY II XR total knee system.
This monocentric protocol is designed to evaluate the efficacy of therapeutic management of symptomatic knee osteoarthritis (resistant to medical first-line treatment) by intra-articular injection of autologous PRP prepared in the same procedure and using a dedicated CE marked medical device and a validated and reproducible method of preparation
Metal ion release from metal implants may have side effects. It can be reduced by coating of the implant. This study compares coated and uncoated TKA.
Total joint replacement is an efficacious treatment for osteoarthritis of hips and knees. Both total knee replacement (TKR) and total hip replacements (THR) have excellent implant survivorship. However, patient satisfaction is lower in TKR than THR. A possible cause of the discrepancy is the unnatural knee kinematics after TKR. Various implant designs have been developed to solve the problem. However, most of the designs are based on experimental data and not on in vivo kinematics. In this study, we will analyze the in vivo kinematics of the Global Medacta Knee Sphere (GMK Sphere) implant and compare it with a well documented design and implant (NexGen Cruciate Retaining (CR), Zimmer Biomet). We assume our study will contribute to the development of more satisfying knee implants.

In this study, the investigators will analyze the in vivo stability of the Global Medacta Knee Sphere (GMK Sphere) implant. Migration of the implants will be monitored with a high precision measuring method called Radiostereometric Analysis (RSA). The investigators assume the investigators study will contribute the development of more satisfying knee implants.
The purpose of this study is to evaluate the effectiveness of ReJoinTM for the Knee Osteoarthritis patients with Cartilage Defects comparing to Sodium Hyaluronate Injection.
