This commentary focuses on the clinical application of magnetic resonance (MR) imaging in the assessment of articular cartilage of the knee. MR imaging is superior to conventional imaging techniques for evaluation of the articular cartilage. Several pulse sequences are advocated for demonstration of the normal articular cartilage and cartilage lesions. However, a consensus has not yet been reached in regard to the most appropriate sequence for evaluation of the articular cartilage. Early morphological changes in the degenerative cartilage are not reliably diagnosed even with the use of tailored MR imaging techniques. The detection of the biochemical changes of cartilage will serve as an important tool for the early diagnosis of cartilage degeneration in the near future. Further prospective studies are needed to establish the role of MR imaging in clinical use.
