Abstract:
The patellar tendon is well suited to sonographic evaluation because it is large and superficial and thus easily demonstrated. Sonography is a focused examination, concentrating on the area of pain and clinical suspicion. Its advantages over MR imaging are the speed of performance, better spatial resolution, capability of dynamic evaluation, and real-time guidance for percutaneous procedures. In addition, the advent of extended field-of-view imaging allows the demonstration of the entire length or cross section of an area of interest, matching MR imaging's ability to display a large anatomical region. This article reviews the sonographic appearances of disorders of the patellar tendon.

Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed to...
