Knee arthroscopic posteromedial portal placement using the medial epicondyle

Posteromedial portals in the knee are used for numerous procedures, including posterior cruciate ligament reconstructions, meniscal transplantation, repair of posterior meniscal tears, removal of loose bodies, and synovectomy. Iatrogenic injury to the sartorial branch of the saphenous nerve is a known complication of posteromedial portal arthroscopy; thus, a reproducible technique for creating posteromedial portals in the knee is critical. The medial epicondyle is an easily identifiable bony landmark and palpable even in patients with a higher body mass index. Use of the medial epicondyle as a landmark for posteromedial portal placement is a reliable technique. This article describes cadaveric neurovascular relationships to the posteromedial portal using the described technique.
