“…They stated that posterior root is difficult to assess by MRI and prone to diagnostic errors because images seemingly show even a single tear as bundles of multiple tears. However, recent reports contributed to raising awareness and interest in the application of MRI for the diagnosis of MMPRTs27,28,29,30,31). Lee et al31) proposed that the MMPRT would not be difficult to diagnose if the diagnosis is based on three different discriminatory features on MRI-plane images along with clinical symptoms: the ghost sign from the sagittal plane (detection rate of 100%), the vertical linear defect (signs of truncation) on the coronal plane (100%), and the radial linear defect on the axial plane (94%) (Fig.…”

“…2). Similarly, Choi et al29) suggested that the sensitivity and specificity of MRI diagnosis of MMPRTs could be high if the diagnosis is based on the presence of radial tears on the axial plane, signs of truncation and extrusion on the coronal plane, and the ghost sign from the sagittal plane. Especially, they reported MRI exhibited a 100% positive value for the diagnosis of radial tears on the axial plane.…”

Damage to the medial meniscus root, for example by a complete radial tear, destroys the ability of the knee to withstand hoop strain, resulting in contact pressure increases and kinematic alterations. For these reasons, several techniques have been developed to repair the medial meniscus posterior root tear (MMPRT), many of which have shown complete healing of the repaired MMPRT. However, efforts to standardize or optimize the treatment for MMPRT are much needed. When planning a surgical intervention for an MMPRT, strict surgical indications regarding the effect of pullout strength on the refixed root, bony degenerative changes, mechanical alignment, and the Kellgren-Lawrence grade should be considered. Although there are several treatment options and controversies, the current trend is to repair the MMPRT using various techniques including suture anchors and pullout sutures if the patient meets the indications. However, there are still debates on the restoration of hoop tension and prevention of arthritis after repair and further biomechanical and clinical studies should be conducted in the future. The aim of this article was to review and summarize the recent literature regarding various diagnosis and treatment strategies of MMPRT, especially focusing on conflict issues including whether repair techniques can restore the main function of normal meniscus and which is the best suture technique to repair the MMPRT. The authors attempted to provide a comprehensive review of previous studies ranging from basic science to current surgical techniques.

“…A root tear could be demonstrated on pre-operative M.R.I in only 72.9% of the patient, while the rest demonstrated degeneration and/or fluid accumulation at the posterior horn without a visible meniscal tear [20]. Other, have reported significantly improved detection ability up to 93.3% sensitivity, 100% specificity and 100% positive predictive value using a variety of magnetic resonance sequences and interpretation signs suggestive of root tears [21] [22] [23]. The detailed for Meniscus tear and its management has been discussed in Figure 1 with a flowchart.…”

It's quite difficult to diagnose the meniscus tear by clinical examination even the experienced orthopaedic surgeon, so this review has shortly focused on clinical examination and its treatment. How to overcome missed diagnosis of meniscus tear in clinical setting? This review article highlighted the importance of early diagnosis and treatment; fortunately, these processes have been vastly improved by advances in Magnetic resonance imaging (MRI) and Arthroscopy. Although partial, subtotal and total meniscectomy is the choice for different types of meniscal tears, there are certain criteria to be meet for undergoing surgical treatment. The most common criteria for meniscal repair include: 1) A vertical longitudinal tear more than 1 cm in length located within vascular zone, 2) A tear which is unstable and displaceable into the joint, 3) An active informed and cooperative patient but younger than 40 years old, 4) A stable knee or wound stabilized with a ligamentous reconstruction. Chronically deformed or degenerative menisci are bottom-out candidates for repair. Most investigators report that only 10% to 15% of meniscal tears can be repaired and that most such repairs are done in association with an anterior cruciate ligament reconstruction. However, this article presents a review of the clinical relevant anatomic, function, repair and healing mechanism, description of the meniscus attachment as well as current strategies for accurate diagnosis and treatment of common injuries to these meniscus attachments.
