Diagnostic Value of a Biomarker of Non-surgical Knee Osteoarthritis (GENU-PERF)

November 28, 2022 updated by: Lille Catholic University

Evaluation of the Diagnostic Value of a Biomarker of Non-surgical Knee Osteoarthritis: Subchondral Bone Perfusion (GENU-PERF)

Osteoarthritis is a very common pathology, especially in an aging population, and a source of disability. Based on standard radiography, the diagnosis is performed late based on the loss of the cartilage thickness. In this context, prosthetic replacement of the joint is a frequent outcome. New diagnostic biomarkers and herapeutic targets are therefore logically research priorities identified by the European League Against Rheumatisms, osteoarthritis ad hoc committee. The inflammation related to the development of this pathology is mainly studied at the cellular level and essentially in animals. Since inflammatory and vascular phenomena are closely intertwined, medical imaging of the subchondral bone vascularization appears interesting.

The dynamic contrast-enhanced T1 Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) technique allows the identification of changes in the osteoarthritic subchondral bone vascularization. In osteoarthritic animals, these changes could be identified before the cartilaginous lesions became visible, and could be correlated with the severity of osteoarthritis.

This study would be the first to correlate subchondral bone perfusion measurements (performed with the DCE sequence) of early cartilaginous lesions of the knee, identified by non-invasive MRI (T2 mapping) in humans. This examination will be performed on a 3 Tesla MRI.

If a correlation is demonstrated in the early stages of osteoarthritis in both humans and animals, then infusion of subchondral bone could become a biomarker of osteoarthritis, and serve as a follow-up evaluation of future treatments.

Detailed Description

Osteoarthritis is a very common pathology, especially in an aging population, and a source of disability. Based on standard radiography, the diagnosis is performed late because it is based on the loss of cartilage thickness. In this context, prosthetic replacement of the joint is a frequent outcome. New diagnostic biomarkers and new therapeutic targets are therefore logically research priorities identified up today by the European League Against Rheumatisms, osteoarthritis ad hoc committee .

The strictly mechanical nature of osteoarthritis is currently being questioned. Indeed, the primitive role of inflammation in the development of this pathology is more and more discussed. This inflammation is today studied at the cellular level and essentially in animals. Since inflammatory and vascular phenomena are closely intertwined, medical imaging of the subchondral bone vascularization appears interesting.

The dynamic contrast-enhanced T1 Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) technique allows the identification of changes in the osteoarthritic subchondral bone vascularization. In osteoarthritic animals, these changes could be identified before the cartilaginous lesions became visible, and could be correlated with the severity of osteoarthritis.

In humans, a preliminary investigator study has recently shown that these changes correlate with the importance of osteoarthritic lesions in patients with advanced osteoarthritis. Up to date, no clinical study has so far been initiated to evaluate the diagnostic value of vascularization markers of subchondral bone in early knee osteoarthritis.

In this context, this prospective monocentric study aims to define the role of DCE medical imaging in the diagnosis of early (non-surgical) patella-femoral osteoarthritis.

This study would be the first to correlate subchondral bone perfusion measurements (performed with the DCE sequence) with early cartilaginous lesions, identified by non-invasive MRI (T2 mapping) in humans. This examination will be performed on a 3 Tesla MRI.

If a correlation is demonstrated in the early stages of osteoarthritis in both humans and animals, then infusion of subchondral bone could become a biomarker of osteoarthritis, and serve as a follow-up evaluation of future treatments.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Correlation between T2 cartilage value and endothelial transfer constant (Ktrans)
Time Frame: Thirty minutes after MRI

T2 (transverse relaxation time) mapping can evaluate the status of the cartilage matrix and identify biochemical changes. T2 is the time constant which determines the rate at which excited protons reach equilibrium or go out of phase with each other. It is a measure of the time taken for spinning protons to lose phase coherence among the nuclei spinning perpendicular to the main field.

Ktrans is a constant representing the volume transfer between blood plasma and extravascular extracellular space. its units are given in values of (1/time)

Thirty minutes after MRI
Correlation between T2 cartilage value and reflux rate (Kep)
Time Frame: Thirty minutes after MRI

The infusion pharmacokinetics parameters are as follows:

Ktrans, Kep Kep represents the time constant for gadolinium reflux from the extravascular extracellular space back into the vascular system

Thirty minutes after MRI
Correlation between T2 cartilage value and initial slope of the kinetic curve
Time Frame: Thirty minutes after MRI

The infusion non-pharmacokinetics parameters are as follows:

- initial slope, time at peak, area under the curve

Thirty minutes after MRI
Correlation between T2 cartilage value and area under the kinetic curve
