Articular cartilage Defect- MRI

The International Cartilage Repair Society has set up an arthroscopic grading system by which cartilage defects can be ranked:
  • grade 0: Healthy cartilage
  • grade 1: the cartilage has a soft spot 
  • grade 2: minor tears visible in the cartilage
  • grade 3: lesions have deep crevices (more than 50% of cartilage layer)
  • grade 4: the cartilage tear exposes the underlying (subchondral) bone

On MRI,  FS 3D gradient-echo MRI is helpful for differentiating between grade 3 and grade 4 cartilage defects.
