All-Inside Meniscus Repair Method for Injury of the Margin of the Anterior Segment of the Meniscus

Abstract Although the outside-in method has been used to treat injuries to the anterior segment of the meniscus, this method has drawbacks including the need to make a skin incision and portals for arthroscopy, pain caused by strangulation of the subcutaneous tissue and joint capsule, and protrusion of the knots. To resolve these problems, we present an all-inside method that enables simple suture of injuries to the anterior segment of the meniscus through arthroscopic portals placed only on the anteromedial and lateral sides without using a specific instrument. This simple, low-cost, low-invasive technique may be useful for suturing marginal injuries to the anterior segment of the meniscus.
