New Meniscus Repair by an All-Inside Knot Suture Technique

The indications for the all-inside knot suture technique include tears in the red-red zone or red-white zone in the meniscus, and a horizontal tear, a vertical tear, and a peripheral tear. First, find an appropriate place for a suture insertion site with a Kateran needle or a spinal needle. Make sure it exits beyond the tear in the meniscus. Once the insertion site is chosen, a suture is passed into and through the joint. The suture is slowly pulled back. You should be able to feel the tip of the suture come out of the joint capsule. If you want to make a vertical suture to suture the tear, move the suture vertically apex. Then insert the suture back into the joint through the capsule. Make sure the suture stays inside the joint. Find and grab the suture with a punch inserted from the clear cannula. Pull the suture out of the joint through the clear cannula with the punch. Tighten the knot with a knot pusher. Then confirm the stability of the sutured site with the probe. Our all-inside knot suture technique can be performed arthroscopically, allowing reliable repair of the torn meniscus.
