Magnetic Resonance Imaging Diffusion Tensor Tractography for Early Osteoarthritis Assessment (TRACTILAGE)
Evaluation of Magnetic Resonance Imaging Diffusion Tensor and Knee Cartilage Tractography Reconstructions for the Study of Early Osteoarthritis
Study Overview
Status
Conditions
Detailed Description
Knee osteoarthritis (OA) is a common and chronic degenerative disease of the articular cartilage. Despite recent progress in the field of cartilage imaging, no routinely used clinical imaging modality has the ability to evaluate and monitor changes in cartilage degeneration.
More and more studies report the benefits of Magnetic Resonance (MR) diffusion tensor imaging (DTI) in the study of early knee osteoarthritis and in particular the new MRI contrasts generating the Track Weighted Imaging (TWI) technique.
This observationnal, pilot, prospective, unrandomized and uncontrolled study aim to evaluate, for the first time, the new MRI tractography maps for the assessment of early knee osteoarthritis. This study doesn't modify the medical care of the patient.

Imaging assessment
All subject of the study have a knee osteoarthritis (OA) and are going to have a knee prosthetic surgery with cartilage excision.
Imaging measurements are conducted on human cartilage samples (2 samples per patient are selected : healthy and severely degraded).
