Sartorial branch of the saphenous nerve in relation to a medial knee ligament repair or reconstruction
Knee Surgery, Sports Traumatology, Arthroscopy, 10/30/09

Wijdicks CA et al. – The authors have characterized the surgically relevant landmark anatomy of the sartorial branch of the saphenous nerve in regards to performing a repair or reconstruction of the medial knee structures. Familiarity with these anatomic landmarks and associated distances from the sartorial branch of the saphenous nerve, the authors can assess the potential area of vulnerability to this nerve branch intraoperatively.

The purpose of our study was to define the course of the sartorial branch of the saphenous nerve in relation to the superficial medial collateral ligament to provide a clinically relevant guide to evoke caution and consideration for this nerve during a medial knee repair or reconstruction. The present study defined the locations of the sartorial branch of the saphenous nerve and characterized a safe zone for a medial knee reconstruction that does not compromise this important branch of the nerve. The most important finding of the present study was that the sartorial branch of the saphenous nerve courses slightly posterior to the medial knee structures, which are most commonly repaired or reconstructed and is in agreement with other authors. Furthermore, the surgical incisions and dissections performed along both femoral attachments of the main medial knee structures and anterior to the posteromedial aspect of the tibia should avoid its course.
