A new modified inside-out repair technique of arthroscopic meniscal repair for peripherally torn menisci is described. Under arthroscopic control, after conventional inside-out technique using meniscal repair set using outside-in technique with 18-gauge needle, horizontal mattress sutures of absorbable monofilament(PDS 2-0) were placed across the tom site and tied over the capsule or fascia. Nearly all portions of meniscus were possible with this technique except most posterior and anterior portions. As this is the modification of inside-out technique, neurovascular complications could be avioded. The problem of outside-in technique, knot irritation inside joint could be avoided also because the knot is outside of the joint.
