-to review the sonographic anatomy and scanning technique knee. -to describe those pathological conditions in which ultrasound (US) has a similar or even higher sensivity and specificity than MRI

Understanding of the anatomy, scanning technique and appearance of pathological conditions is essential for proper interpretation of US findings. We review US and MRI studies performed in 245 patients with symptoms referred to a specific knee area; those patients with diffuse or meniscal symptoms were excluded. We describe the songraphic appearance of the four anatomic compartments in which knee is divided: anterior, medial, lateral and posterior. We explain how to perform a dynamic US study (with active and passive mobilization) and to obtain images of the full course of the tendons and collateral ligaments in different planes. Illustrative examples of main tendinous , ligaments and recess diseases are shown. US imaging of other structures, such as patellar cartilage, supra patellar recess and peroneal/ tibial nerve. We emphazise the advantages of US exam compared to MRI. US is especially useful in the study of tendons of anterior compartment, particularly in child in which MRI will be subject to the effects of anisotropy and in the evaluation of posterior compartment and collateral ligaments.
