The Posteromedial-Transseptal Portal for Arthroscopic Suture Hook Repair of Posterior Horn Tears and Popliteomeniscal Fascicles Tears of the Lateral Meniscus

Abstract

We present a convenient and safe arthroscopic technique for suturing the lateral meniscus. In this technique, the clinician establishes a conventional posteromedial approach in the figure-of-four position of the knee by using the anterolateral and anteromedial observation approaches. Behind the posterior cruciate ligament, an operational approach is formed through the posterior mediastinum of the knee joint. Through this approach, suture hook can be brought to the posterior horn and body of the lateral meniscus, thus simplifying the suture of the lateral meniscus. We have used this technique to finish all-inside suture using suture hooks in a variety of types of lateral meniscal injuries, including longitudinal posterior horn tears, bucket handle meniscus tears, and tears around the popliteal hiatus area. Compared with traditional lateral meniscal all-inside suture technology through anteromedial or anterolateral approaches, this technology can suture more accurately, safely, and conveniently, avoid the involvement of the popliteal tendon suture, and the lower risk of complications such as popliteal vascular and nerve injury occur.
