The purpose of this study was to evaluate cartilage-bone interface in osteochondral samples from human tibia with varying degrees of degeneration using SWIFT. For reference, micro-computed tomography (micro-CT) imaging, histopathological scoring (OARSI) and histological evaluation were used. Differences in the appearance of the calcified cartilage and subchondral bone were detected with SWIFT, depending on the degree of OA. SWIFT was capable of elucidating tissue changes associated to the degree of OA.
