The infrapatellar fat pad (IFP) is an intracapsular, but extrasynovial structure, located between the patellar tendon, femoral condyles and tibial plateau. We have recently described the microscopic orgnisation of the IFP, which consists of white adipose tissue (fibroadipose, lobular type), organised in lobuli delimited by thin connective septa. The aim of the study is to describe the sonoanatomical features of IFP in subjects without knee pathology during flexo-extension movements. Twentyfour volunteers subjects with no history of knee diseases (5M, 19F, mean age: 45yo)were analysed. Examinations was performed using high-resolution grey-scale ultrasound. The mean area of the deepest recognisable adipose chamber in extension were 0,12 and in flexion 0,19 mm2, and the circumference were in extension 1,36 and in flexion 1,19 mm. The area of the closest adipose chamber to the patellar tendon were in extension 0,29 and flexion 0,12 mm2(p
