Arthroscopic Transtibial Medial Meniscus Posterior Root Repair Using the “Meniscal Track” to Locate the Anatomical Footprint

The medial meniscus posterior root tears are a common problem in early elder patients. From a biomechanical study, the anatomical repair demonstrated a restored contact area and contact pressure than the nonanatomical repair. Nonanatomical repair of the medial meniscus posterior root resulted in decreased tibiofemoral contact area and increased contact pressure. Various surgical repair techniques were reported in the literature. However, there was no reported precise arthroscopic landmark to define the anatomical footprint of the posterior root attachment of the medial meniscus. We propose the “meniscal track”, an arthroscopic landmark to guide the location of the anatomical footprint of the medial meniscus posterior root attachment.
