Outside-in Continuous Meniscal Suture Technique of the Knee

Abstract

The meniscus is largely responsible for the health and longevity of the knee. It has diverse functions, being fundamental in load absorption and distribution and even in joint stability. To preserve meniscal functions and prevent the occurrence of osteoarthritis after meniscectomy, several meniscal repair techniques have been developed. To perform meniscal repair in anterior horn, the outside-in technique is the most used. There are few devices for performing them, with most of the surgical techniques described using needles. Our group uses a device capable of performing meniscal repair in different ways. Our objective is to describe a continuous outside-in meniscal repair technique, especially indicated for anterior horn and meniscus body tears, with the "Meniscus 4-All suture device." The continuous outside-in meniscal suture technique using this device is easy to perform, inexpensive, fast, and reproducible, minimizing the risk of soft-tissue entrapment. In addition, it allows the surgeon to perform meniscal repair in the posterior horn in extensive injuries with the same repair device, just switching to inside-out technique.
