Clinical Trial Summary

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.
