Visualization and reduction of a mensical capsular junction tear in the knee: an arthroscopic surgical technique.

: Meniscal injuries commonly occur concomitantly with anterior cruciate ligament (ACL) injuries. Although many types of meniscal injuries have been described in the literature, there has not been much focus on meniscal capsular junction (MCJ) tears. This lack of attention is concerning given that, in a survey of 67 orthopedic surgeons, 88% indicated that MCJ tears could be a source of chronic pain. In addition, we reviewed 781 ACL reconstructions at our clinic and found a 12.3% incidence of MCJ tear with primary ACL injury and a 23.6% incidence of MCJ tear with revision ACL reconstruction. In this article, we describe an arthroscopic repair technique for MCJ tears at the posterior aspect of the medial meniscus root. The repair uses an accessory posterior medial portal. The technique can also be used for significant posterior medial capsular tears.
