How to Perform Concomitant Medial Meniscus Pull-Out Repair With Medial Open-Wedge High Tibial Osteotomy Without Technical Failure.

Abstract

Varus alignment of the knee joint (varus >5°) is known as a poor prognostic factor for medial meniscus root repair, and alignment correction is recommended in patients with varus deformity and medial meniscus root tears. However, simultaneous medial meniscus pull-out repair and high tibial osteotomy are technically demanding procedures due to the long surgical time, poor visualization, and breaking of the pull-out sutures during high tibial osteotomy procedures. In the present Technical Note, we will introduce a surgical method to perform 2 procedures simultaneously without technical difficulty. The main surgical techniques are as follows. (1) Release the superficial medial collateral ligament before arthroscopic medial meniscus pull-out repair, which secures sufficient working space and visualization. Therefore, the operation time could also be reduced by performing the arthroscopic procedure with the anterior portal. (2) Protect the pull-out sutures with an ENDOBUTTON reamer, which prevents pull-out sutures from breaking during the high tibial osteotomy procedure.
