Abstract

|
A medial meniscus posterior root tear (MMPRT) with extrusion results in the loss in transmission of circumferential hoop stress, leading to significantly increased peak contact pressure at the tibiofemoral joint and to accelerated articular cartilage degeneration. For these reasons, the need to diagnose and treat MMPRTs early has been highlighted in recent years. With remarkable developments in imaging technology and in arthroscopy, MMPRTs are being diagnosed earlier and earlier. Recently, various repair techniques other than meniscectomy have evolved, aimed at restoring viability and the biomechanical properties of the torn meniscus. While much of the current studies on meniscal repair have demonstrated a high rate of healing and improvements in terms of subjective and functional parameters, there is no consensus concerning the optimal technique to manage MMPRTs. This article aims to present a review of the literature and summarize the clinically relevant anatomical, biomechanical, and functional roles of the medial meniscus, as well as the current trends regarding surgical techniques of MMPRTs. However, because the debate over surgical technique and the effectiveness of root repair for joint preservation remains controversial, further studies are still needed.
