Arthroscopic Pullout Repair of a Complete Radial Tear of the Tibial Attachment Site of the Medial Meniscus Posterior Horn

Abstract

We developed an effective arthroscopic pullout technique for repairing complete radial tears of the tibial attachment site of the medial meniscus posterior horn (MMPH). In our technique, the torn meniscus is reattached to the tibial plateau immediately medial or anteromedial to the posterior cruciate ligament (PCL) using two No. 2 Ethibond sutures (Ethicon, Somerville, NJ). After a complete radial tear of the tibial attachment site of the MMPH and its reparability were confirmed, using a Caspari suture loaded with a suture shuttle, one No. 2 Ethibond suture is placed through the meniscus, through the red-red zone, 3 to 5 mm medial to the torn edge of the MMPH, and the other is passed through the meniscocapsular junction 3 to 5 mm medial to the torn edge of the meniscus. Then, a tibial tunnel, 5-mm in diameter, is made from the anteromedial aspect of the proximal tibia to the previously prepared tibial plateau, immediately medial or anteromedial to the PCL, and the two No. 2 Ethibond sutures are pulled out through the tibial tunnel and then fixed to the proximal tibia using a 3.5-mm cortical screw and washer. Firm reattachment of the torn meniscus was confirmed arthroscopically.
