Imaging of articular cartilage.

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.

Hyperextension injury of knee sustained in a 20 year old man. Coronal FS PD-weighted image of knee joint shows a mildly displaced chondral flap (white arrow) involving the weight-bearing surface of the medial femoral condyle. There are kissing bone marrow contusions of the medial aspect of the anterior tibia and femur (yellow arrow) secondary to the hyperextension injury. Valgus stress occurring at the hyperextension injury resulted in the medial location of the kissing contusions

Figure 6: Hyperextension injury of knee sustained in a 20 year old man. Coronal FS PD-weighted image of knee joint shows a mildly displaced chondral flap (white arrow) involving the weight-bearing surface of the medial femoral condyle. There are kissing bone marrow contusions of the medial aspect of the anterior tibia and femur (yellow arrow) secondary to the hyperextension injury. Valgus stress occurring at the hyperextension injury resulted in the medial location of the kissing contusions

Mentions: Proton density-weighted sequence has the feature of T1 and efficacy of T2, based upon the local concentration of the hydrogen nuclei [Figure 5]. The intact articular cartilage has low signal intensity as compared to the bright fluid signal intensity, increasing the conspicuity of the focal surface lesions[79] [Figure 6].
