Abstract Introduction There is a lack of data relating the macroscopic appearance of cartilage to its ultrasound properties. The purpose of the present study was to evaluate degenerated cartilage and healthy-looking cartilage using an ultrasound system. Methods Ultrasound properties - signal intensity a measure of superficial cartilage integrity echo duration a parameter related to the surface irregularity and the interval between signals that is time of flight - which is related to the thickness and ultrasound speed of .
