Arthroscopic Suture Anchor Repair With Modified Mason-Allen Technique for Medial Meniscus Posterior Root Tear.

Abstract

Medial meniscal posterior root tears are a well-known risk factor for knee osteoarthritis. Transtibial pullout repair is mostly reported, and good results have been reported for pullout repair using the modified Mason-Allen technique; techniques using suture anchors have also been reported. Herein, we report a technique for suture anchor repair using the modified Mason-Allen technique. An anchor with 2 sutures is inserted at the attachment site of the medial meniscal root via the posteromedial portal using a curved guide. A vertical suture was made on the posterior portion of the meniscus with one suture, and another suture is then inserted just medial to the vertical suture and tied over the first vertical suture using a self-locking sliding knot through the anteromedial portal. This technique may potentially improve medial meniscal posterior root tears repair outcomes and provide some technical advantages, especially in combination with high tibial osteotomy.
