A meniscal tear is one of the most common injuries of the knee. There are three main types of meniscal repairs. These include inside-out, outside-in, and all-inside repairs. Although a combination of these techniques can be used when repairing large, complex meniscal tears, the inside-out meniscal repair has been the gold standard of repair techniques. Here is a technique for repairing the meniscus from the inside out using a hollow needle.
1. Prepare a hollow 16G or 17G hollow biopsy needle and No. 2 or No. 0 suture.
2. The needle enters the joint through the other side of the torn meniscus. For example, the anterolateral entrance for a medial meniscus tear, or vice versa. This option avoids damage to the posterior neurovascular structures.
Find a suitable entry point on the torn side of the meniscus, then the needle passes through the meniscus and the tissue outside it to the outside of the skin. The needle and suture come out together.
3. The needle is withdrawn to the joint and positioned on the other side of the tear. The needle is passed through a second point on the meniscus and exits through the skin near the first exit point.
4. Remove the suture from the needle. Skin incision, tie a knot on the joint capsule.
