Reliability of tibiofemoral contact area and centroid location in upright, open MRI.

ABSTRACT:

Background

Imaging cannot be performed during natural weightbearing in biomechanical studies using conventional closed-bore MRI, which has necessitated simulating weightbearing load on the joint. Upright, open MRI (UO-MRI) allows for joint imaging during natural weightbearing and may have the potential to better characterize the biomechanical effect of tibiofemoral pathology involving soft tissues. However open MRI scanners have lower field strengths than closed-bore scanners, which limits the image quality that can be obtained. Thus, there is a need to establish the reliability of measurements in upright weightbearing postures obtained using UO-MRI.

Methods

Knees of five participants with prior anterior cruciate ligament (ACL) rupture were scanned standing in a 0.5 T uprigh
