[Problem] To provide an ultrasonic analysis device, ultrasonic analysis method, and program for quantitatively analyzing the surface condition of cartilage. [Solution] The present invention makes use of the property of ultrasonic waves being diffusely reflected at the surface of modified cartilage. An analysis unit uses sets of data comprising the intensity of echo signals detected by an intensity detection unit and the angle of incidence of ultrasonic signals on the surface of cartilage, to quantitatively analyze the surface condition of cartilage on the basis of the distribution of the sets of data. The angle of incidence of the ultrasonic signals on the surface of the cartilage is inputted with, for example, a keyboard.
