The current study reports the sensitivity of acoustical parameters estimated at high frequency to the osteoarthritic morphological and structural changes in patellar cartilage in rat knees. Osteoarthritis (OA) was induced by a single intra-articular injection of mono-iodo-acetic acid in right knees. OA patellas and their contralateral controls were excised at regular intervals after injection and were examined in vitro with a scanning acoustical microscope operating with a poly(vinylidene di… CONTINUE READING
