Brief Summary:
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.

Primary Outcome Measures :
  1. Proportion of patients who have one-point increase in the quality score of OARSI [ Time Frame: 3 years ]
    Patients who over the 3-year follow-up period will have a one-point increase in the quality score of OARSI compared to the initial pinch score (Altman RD et al, Osteoarthritis and Cartilage 1995).

  2. Proportion of patients whose joint space reduction is greater than the smallest reliable detectable difference. [ Time Frame: 3 years ]
    Patients whose joint space reduction is greater than the smallest reliable detectable difference.

  3. Proportion of patients who have a decrease in joint space of 0.5 mm [ Time Frame: 3 years ]
    Patients who have a decrease in joint space of 0.5 mm or more over the 3-year period (Cooper C et al, CMRO 2012).

Secondary Outcome Measures :
  1. Proportion of patients who have evolution of medial femoral tibial joint space [ Time Frame: 3 years ]
    Evolution of medial femoral-tibial joint space

  2. Number of particpants who will have evolution of strucutral lesion score [ Time Frame: 3 years ]
    Evolution structural lesion score is OARSI (OsteoArthritis Research Society International score)

  3. Evolution of algo-functional scores (OAKHQOL) [ Time Frame: 3 years ]
    OAKHQOL (OsteoArthritis of Knee and Hip Quality Of Life) scores

  4. Evolution of algo-functional scores (WOMAC) [ Time Frame: 3 years ]
    WOMAC (McMaster Western Ontario questionnaire ) scores

  5. Change From Baseline in quality of life Scores [ Time Frame: 3 years ]
    Short Form 36

  6. Change From Baseline in Pain Scores on the Visual Analog Scale [ Time Frame: 3 years ]
    Pain visual analogical score
