Arthroscopic Knotless Anchor Through High Posterolateral Portal for Treating Medial Meniscal Posterior Root Tears.

Surgery can repair medial meniscal posterior root tears to restore the biological function of the meniscus. Transtibial pullout repair is most common, but suture anchor repair offers great biomechanical stability and avoids the bungee effect. Suture anchor repair through the posteromedial portal has limitations, which have been widely reported. This article describes our technique using a knotless anchor through the high posterolateral portal for the treatment of medial meniscal posterior root tears; it can achieve an anatomic repair. Through the use of the high posterolateral portal, an excellent degree of verticality between the suture anchor and the anatomic footprint of the medial meniscal posterior root can be achieved. Additionally, we summarize the advantages, disadvantages, pearls, and pitfalls of the technique.
