“…The medial menisci were described by Flick et al [ 14 ] as half, two-thirds, or three‑fourth ellipse, while the lateral menisci were compared to an almost complete circle. However, Charles et al [ 15 ] classified the menisci based on the relative size of the anterior and posterior cornua and the degree of curvature.…”

The medial and lateral menisci of the knee joint are the functional unit that helps to increase the depth of articular surfaces on the head of a tibia for the reception of femoral condyles. Menisci are important for the distribution of load and thus help to reduce stress on the knee joint. The anatomical knowledge of morphology and morphometry of menisci is vital while performing surgeries in cases of meniscal injury. The study aimed to define the variational anatomy of the menisci of the knee joint. Material and MethodsNinety-six cadaveric knees of 48 cadavers were included in the study. Different shapes of both; lateral and medial menisci were recorded. The peripheral lengths and inner lengths of the menisci were measured with the nonelastic cotton thread. Menisci were divided into three parts; anterior, middle, and posterior. The maximum width and thickness of each part of the menisci were measured and documented. Distance between the medial and lateral meniscus in each knee was measured at the anterior and posterior ends. The most anterior and the most posterior part of each meniscus was determined and the distance between these parts of each meniscus was measured and recorded as the distance between two horns. ResultsFour morphological types of menisci were found; in medial menisci, the most common was crescent-shaped (53%), and in lateral menisci, the most common shape was c-shape (62.5%). The average peripheral length of the medial menisci was 92.0 mm and the lateral menisci was 96.08 mm while the average inner length of the medial and lateral meniscus was 56.19 mm and 58.92 mm respectively. The anterior third of the medial as well as lateral meniscus was thinnest while the posterior third was thickest. The width of the medial menisci was less at the anterior end and was more at the posterior ends while the width of the lateral meniscus was almost the same at the anterior, middle, and posterior ends. ConclusionThe findings of the present study will be helpful for surgeons while planning and performing surgical procedures and for anatomists during routine teaching.

“…[ 8 ] Charles, on the other hand, categorized the menisci based on the relative size of the anterior and posterior cornua as well as the degree of curvature. [ 9 ] A discoid LM in a cadaver specimen was described by Young[ 10 ] in 1889. The meniscus of the knee, particularly the LM, is discoid rather than semilunar in shape, which is an atavistic abnormality.…”

Introduction: Sports are the leading cause of joint injuries, particularly in the knees. Knee menisci are an important functional unit that aids in load distribution and hence reduces stress on the knee joint. Meniscal morphology provides information on exact size and shape, which is important for meniscal transplantation in cases of meniscal damage. The study’s goal is to determine the morphological variation in the shape of menisci, as well as the width and thickness of menisci. Method: This study was conducted at the Rajendra Institute of Medical Sciences (RIMS) Ranchi, Department of Anatomy. In this study, 100 menisci were taken from 50 adult cadaver knee joints available in the dissection hall. Result: Six morphological kinds of menisci were identified after a morphological and morphometric study of 100 menisci. The most common crescent-shaped menisci (96%) were found in 50 medial menisci (MM), while the most common C-shaped menisci were found in 50 lateral menisci (LM, 94%). There was no statistically significant difference in thickness between the anterior, middle, and posterior thirds of the MM in the morphometric analysis. The thickest section of the lateral meniscus (LM) was in the middle third. There was no significant variation in the width of the LM among the different thirds in the current study. The posterior portion of the medial meniscus (MM), on the other hand, was the widest. Conclusion: The findings of this study support meniscal anatomy in terms of surgical technique and arthroscopy of the knee joint, as well as contributing to a better understanding of meniscal architecture and meniscal transplantation. As a result, health workers who treat meniscal injuries should be aware of the probable anatomical differences.

“…Flick & Rudolph [7] described the medial meniscus (MM) as a half, two third or three-fourth ellipse and stated that the lateral could be compared to an almost complete circle. In contrast, Charles [8] classified the menisci, both on the basis of the relative size of the anterior and posterior cornua and also on the degree of curvature. In 1889, Young [9] described a discoid lateral meniscus in a cadaver specimen.…”

ABSTRACT-INTRODUCTION-The Menisci are semi-lunar crescent shaped fibro-cartilages which serve to widen and deepen the articulation of tibial surfaces that receive the femur condyles forming the knee joint. OBJECTIVE-To assess the incidence of different shapes of the medial and lateral meniscus and the incidence of discoid meniscus in the North Indian population. METHODS-The study included 112 menisci from 56 adult cadavers knee joint irrespective of sex that were preserved in 10% formalin. After methodical dissection procedure the morphological variants of the shape of menisci were macroscopically noted and classified. The medial menisci were sub-grouped as crescent-shaped, V-shaped, U-shaped, C-shaped and sickle shaped. Lateral menisci were sub-grouped as crescent-shaped, C-shaped and discoid-shaped. RESULTS AND CONCLUSIONS-In the present study, 80% of the medial menisci were crescent shaped, 12.8% were V-shaped while 7.2% sickle-shaped. Among the lateral menisci, maximum number of specimen were C-shaped i.e. 78% followed by crescent shaped in 19% and discoid shaped in 3% specimen. Knowledge of various shapes of meniscii would be useful for health professionals who treat athletes with suspected meniscal tear.
