Imaging of articular cartilage.

Paunipagar BK, Rasalkar D - Indian J Radiol Imaging (2014)

Bottom Line: It is frequently exposed to trauma, degeneration, and repetitive wear and tear.MRI has played a vital role in evaluation of articular cartilage.With the availability of advanced repair surgeries for cartilage lesions, there has been an increased demand for improved cartilage imaging techniques.

ABSTRACT
We tried to review the role of magnetic resonance imaging (MRI) in understanding microscopic and morphologic structure of the articular cartilage. The optimal protocols and available spin-echo sequences in present day practice are reviewed in context of common pathologies of articular cartilage. The future trends of articular cartilage imaging have been discussed with their appropriateness. In diarthrodial joints of the body, articular cartilage is functionally very important. It is frequently exposed to trauma, degeneration, and repetitive wear and tear. MRI has played a vital role in evaluation of articular cartilage. With the availability of advanced repair surgeries for cartilage lesions, there has been an increased demand for improved cartilage imaging techniques. Recent advances in imaging strategies for native and postoperative articular cartilage open up an entirely new approach in management of cartilage-related pathologies.

Figure 13: Axial 2D fat-saturated PD-weighted fast spin-echo image of knee joint in a 47 year old man shows arthroscopically confirmed superficial cartilage fibrillation (arrows) categorized as grade 2 cartilage lesion

Mentions: Chondral lesions are graded based upon the thickness of articular cartilage disruption. The cartilage may undergo swelling (focal or diffuse) represented as an area of hyperintensity on fluid-sensitive sequence [Figure 12]. Focal disruption of cartilage may be a linear cleft or multiple linear clefts representing fissures of variable depths [Figure 13]. Full-thickness cartilage separation from the tidemark zone results in chondral flap injuries or delamination of articular cartilage [Figure 14]. Associated with injury to articular cartilage, there may often be injury to subchondral bone, which may be represented as bone marrow edema, subchondral bone fracture, or displaced fracture [Figure 15].
