Popliteal fossa

Dr Daniel J Bell and Dr Craig Hacking et al.

The popliteal fossa (plural: fossae) is a diamond or rhomboid-shaped fat-filled space in the posterior knee. The space is extremely dynamic, allowing for its neurovascular contents to move during the extreme range of motion produced by knee flexion and extension.
