Up to two thirds of patients with anterior cruciate ligament rupture have a combined medial meniscus posterior horn tear. Researchers have proven the importance of repairing this tear to enhance stability after anterior cruciate ligament reconstruction. However, repairing the meniscal tear can be sometimes cumbersome and difficult or even impossible in certain circumstances, especially in places such as the posterior horn of the medial meniscus. We devised a simple and easy method of all-inside suturing of medial meniscus posterior horn tears using a 2-posteromedial portal system. Furthermore, with a modification of our technique, a clinician can not only suture single but also double longitudinal medial meniscus posterior horn tears.
