Demonstration of knee ultrasound shear wave elastography application. PT: patellar tendon, H: Hoffa fat pad, P: patella, T: tibia, A: anterior cruciate ligament. Figure 1a and b: Localization of anatomical regions in the ultrasound images. The distal portion of the ACL is observed between the patella and tibia, posterior to the Hoffa fat pad. Figure 2a and b: Consecutive ROIs (Regions of Interest) used in elastography measurements and the elastography measurements on the ACL are observed
