We presented simple data showing that the ultrasound response of articular cartilage may be related to its International Cartilage Repair Society grading and concluded that ultrasound evaluation using the signal intensity - dependent on the ultrasound reflection coefficient at the cartilage surface - may be helpful to differentiate International Cartilage Repair Society grades especially grade 0 from grade 1 cartilage 2 . Our ultrasound system obtains indirect information on intrinsic physical characteristics of living human articular cartilage in vivo. We recognize that the ultrasound .
