Plate Hooking Transtibial Medial Meniscus Posterior Root Pull-Out Repair with Medial Open-Wedge High Tibial Osteotomy for Knee Osteoarthritis with Medial Meniscus Posterior Root Tear.

Medial meniscus posterior root tears (MMPRT) are a risk factor for knee osteoarthritis (KOA) because it involves disruption of the hoop structure of the meniscus. In recent years, MMPRT pullout repair has been performed to restore the native anatomy of the meniscus attachment. In addition, medial open-wedge high tibial osteotomy (MOWHTO) has been performed with MMPRT pullout repair to reduce the pressure on the medial compartment. However, it has been noted that when MMPRT pullout repair and HTO are performed simultaneously in a patient, the locking screws of the plate interfere with the tibial bone tunnel, which damages the suture. In this technical note, we developed a method to reduce the probability of interference by placing the plate further anteroinferior when digging the bone tunnel from the PM position. This technical note aimed to provide a comprehensive description of the safety of transtibial MMPRT repair with MOWHTO for medial KOA with MMPRT.
