Common peroneal nerve
The common peroneal nerve runs from the center of the popliteal fossa laterally and curves distally around the fibula head in an anterolateral direction. It separates into a superficial and a deep branch. Injury of this nerve will result in severe functional deficits.
The saphenous nerve runs distally along the anteromedial aspect of the thigh and as it passes the knee joint it branches off the infrapatellar nerve. Injury of this nerve will not result in functional deficit, but can give rise to cutaneous sensory.
