Transosseous Posterior Meniscal Root Reinsertion Using Knotless Anchor for Tibial Fixation.

A technique for posterior meniscal root reinsertion is presented. With the arthroscope in the central transtendinous portal for a better view, a 5-mm transtibial tunnel is created with the aid of an anterior cruciate ligament guide open to 45°. A suture device, which consists of a long needle with an eyelet on its tip, is introduced through the tunnel with a suture thread inserted through the eyelet, while the meniscus is stabilized with a grasper inserted through the anterior portal. The meniscus is pierced with the device, and the suture thread is recovered with said grasper. A finger-tip pincer is inserted through the tunnel to recover the thread. The same procedure is followed to perform a second stitch. A lasso loop is made for both stitches, and the resultant tails are knotted to a knotless suture anchor, which is inserted in the anterior cortex of the tibia, 1 cm distal to the extra-articular end of the tibial tunnel.
