Title: MRI evaluation of acute articular cartilage injury of knee
Abstract: Objective To study the MRI manifestation of acute articular cartilage injury of knee for evaluating the extension and degree of the injury and guiding treatment. Methods MRI of 34 patients with acute articular cartilage injury of knee within one day to fifteen days confirmed by arthroscopy and arthrotomy was reviewed and analyzed, with emphasis on articular cartilage and subchondral lesion. And every manifestation on MRI and that of arthroscopy and operation was compared. Results The articular cartilage injury was diagnosed on MRI in 29 of 34 cases. Cartilage signal changes were found only in 4. The changes of cartilage shape were variable. Thinning of focal cartilage was showed in 3, osteochondral impaction in 3, creases of cartilage in 3, disrupted cartilage with fissuring in 13, cracks cartilage in 2, and cracks cartilage with displaced fragment in 1. Bone bruise and occult fracture were found only on MRI. Conclusion The assessment of MRI and arthroscopy in acute articular cartilage injury are consistent. Combined with arthroscopy, MRI can succeed in assessing the extension and degree of acute articular injury and allowing treatment planning.
