Arthroscopic Saucerization With Inside-Out Repair and Anterocentral Shift of a Discoid Lateral Meniscus With Retention of Adequate Volume of Residual Meniscus.

Abstract: Preservation of the meniscus has been shown to influence the progression of osteoarthritic changes in the knee. Discoid lateral meniscus (DLM) is classified on the basis of the presence and location of instability resulting from deficient capsular attachments. Recently, meniscal stabilization after saucerization was recommended in cases of DLM to preserve the meniscus shape and avoid the progression of osteoarthritis. However, it is difficult to identify the accurate resection volume and residual meniscal width during surgery, especially when there is an anterocentral shift of the DLM. This Technical Note describes an arthroscopic technique for an anterocentral shift of the DLM in which we highlight the resection point and confirm the methods of retaining an adequate volume of residual meniscus to restore and maintain the shape and function of the meniscus.

Level Of Evidence: Level 1, Knee; Level 2 Meniscus.
