Arthroscopic Transtibial Pull-Out Repair for Meniscal Posterior Root Tear: The Slip Knot Technique

A meniscal root tear can increase the tibiofemoral contact pressure to approximate that of total meniscectomy, and eventually lead to degenerative change. An anatomic and stable meniscal root repair is essential in restoring the tibiofemoral contact pressure back to that of a normal knee. Suture anchor technique and pull-out suture technique are the two main arthroscopic root repair procedures with equivalent success; nonetheless, there remains a lack of an optimal technique with a biomechanical property matching that of the intact root. This article presents a technically simple, fast, and robust pull-out suture construct that incorporates two slip-knot locking loops at the meniscus-suture interface. This technique can be utilized for both medial and lateral posterior root repair as well as concomitantly with cruciate ligament reconstruction.
