“…Their findings are in agreement with a cross-sectional aspect of the present loss of the structure that most robustly holds the meniscus in the normal anatomic position (2). Risk factors for meniscal root tears include female sex, high BMI, greater varus mechanical axis angle, and low levels of exercise (21). This entity seems to be more common than previously thought, with a frequency rate of around 10% (722 of 7148) in patients undergoing knee arthroscopy (22).…”

MPH Purpose:To assess the association of meniscal root tear with the development or worsening of tibiofemoral cartilage damage. Materials and Methods:Institutional review board approval and written informed consent from all subjects were obtained. A total of 596 knees with radiographically depicted osteoarthritis were randomly selected from the Multicenter Osteoarthritis study cohort. Cartilage damage was semiquantitatively assessed by using the Whole-Organ Magnetic Resonance Imaging Score (WORMS) system (grades 0-6). Subjects were separated into three groups: root tear only, meniscal tear without root tear, and neither meniscal nor root tear. A log-binomial regression model was used to calculate the relative risks for knees to develop incident or progressing cartilage damage in the root tear group and the meniscal tear group, with the no tear group serving as a reference. Results:In the medial tibiofemoral joint, there were 37 knees with isolated medial posterior root tear, 294 with meniscal tear without root tear, and 264 without meniscal or root tear. There were only two lateral posterior root tears, and no anterior root tears were found. Thus, the focus was on the medial posterior root tear. Conclusion:Isolated medial posterior meniscal root tear is associated with incident and progressive medial tibiofemoral cartilage loss.q RSNA, 2013

“…They concluded from their clinical findings that arthritis in the medial compartment is closely linked to the development of MMPRT. Hwang et al20) reported that the risk of MMPRT was higher by 5.9 times in females than males, 4.9 times if body mass index was more than 30 kg/m 2 , 3.3 times in knees with a varus mechanical axis, and 2.7 times in patients with a lower level of sports activities.…”

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.

“…1,2 Meniscus root tears can occur in both acute and chronic settings, with the posterior meniscus roots being most commonly affected. [3][4][5] Whereas posterior lateral meniscus root tears are usually associated with acute tears of the anterior cruciate ligament in young male patients, 6,7 posterior medial meniscus root tears (PMMRTs) are mainly the result of degenerative meniscal disease in middle-aged women 8,9 (Fig 1A).…”
