Abstract

The posteromedial horn of the medial meniscus is prone to injury, and repair of a tear in this portion of the medial meniscus is especially challenging for the arthroscopist. We present a novel technique that allows good management of the posterior horn of the medial meniscus, even in patients with tight medial compartments. This technique uses two standard portals (the anterolateral portal and the anteromedial portal) to conduct arthroscopic examination, and uses a third portal as the workhorse portal to manage the posterior region so that the posterior horn tear can be easily removed. This new third portal is named the anterior-medial collateral ligament portal, and is positioned anterior to the anterior rim of the medial collateral ligament. This three-portal technique decreases the difficulty associated with management of the posteromedial region in knees with tight medial compartments.
