Infrapatellar branch of the saphenous nerve
The infrapatellar branch of the saphenous nerve crosses the anteromedial knee along a variable course. Because of its position it can be injured or trapped in scars, especially after knee surgery. This page shows its course on the 3D model.
Anatomy of the passage
The infrapatellar branch crosses fascial planes at the anteromedial knee. Its variable course exposes it to injury or entrapment by scars, especially after local procedures. The illustration shows one anatomical variant and not a position identical in every person.

Ultrasound landmarks
At the anteromedial knee, the infrapatellar branch of the saphenous nerve emerges beside sartorius and crosses superficially towards the infrapatellar region.
