Imaging of Articular Cartilage

Abstract

Imaging plays a crucial role in the evaluation of articular cartilage and cartilage repair procedures. Imaging helps guide therapeutic interventions and also assessment of new pharmacologic and surgical treatments. There have been many exciting developments in imaging of articular cartilage, especially using magnetic resonance imaging (MRI). Currently, MRI is the best imaging modality for assessment of normal articular cartilage, cartilage lesions, and cartilage repair. The MRI of articular cartilage provides accurate assessment of changes of cartilage surface, thickness, and signal as well as changes of subchondral bone and bone marrow. Following cartilage repair surgery, MRI provides thorough evaluation of the repair tissue and associated complications if they occur.
