“…Comparing the mean outer circumference of the medial and lateral menisci in the present work, the medial meniscus exhibited larger values than that of the lateral which was statistically significant. This finding is concordant with the results provided by Braz and Silva [16] , Murlimanju et al, [6] , Ashwini et al, [5] and Rao et al, [17] . This finding could be explained be the fact that the medial tibial condyle is larger than the lateral.…”

“…The present cadaveric study is in agreement with Rao et al, [17] who concluded that the measurements of width of anterior and middle 1/3 of lateral meniscus were much higher than those of medial meniscus which is statistically significant, while the posterior 1/3 of medial meniscus was wider than the lateral but it was statistically nonsignificant.…”

“…The mean value of the outer circumference of the lateral meniscus in the present study was 88.20 ±4.95 mm which is which is higher than that recorded by Rao et al, [17] 87.3 ±4.9mm, and much higher than the results of Ashwini et al, [5] who found it to be 83.28 ±7.4 mm. On the other hand, the present result is lower than that of Murlimanju et al, [6] who reported it as 90.25 ±9.36mm.…”

“…In the present cadaveric study, the mean value of the outer circumference of the medial meniscus was 95.16±3.62mm. This result is higher than those recorded by Braz and Silva [16] who reported it to be 91.85 ±5.66mm, Ashwini et al, [5] who reported it as 90.12 ±8.0mm and far more than Rao et al, [17] who studied 100 knees of the formalin fixed adult human cadavers in Indian population and found it to be 86.4 ±4.5mm. On the other hand, the present finding is lower than that of Murlimanju et al, [6] who recorded it as 99.06 ± 11.21mm.…”

Background: Meniscus injury is common in daily life as well as in sports activities especially football players and runners. Variation of form, thickness and width of the menisci can determine the possibility and type of their injury. Aim of Study:The aim of this work is to study the different measurements of the different parts of both menisci (distance, circumference, thickness and width) in cadaveric specimens and to correlate these measurements with in vivo MRI measurements, including sex difference of different meniscal parameters. Materials and Methods:The cadaveric study included fifty menisci of 25 knees of formalin fixed adult human cadavers; Measurements were done with the aid of sliding Vernier caliper and were recorded manually. The MRI study included 76 patients (38 male and 38 female), the caliper used for measurements was inbuilt software. The measurements were performed by the same radiologist in all the scans, to prevent inter-observer error.Results: In the cadaveric study; correlation between the different parameters showed statistically significant positive correlation, while in the MRI study; no significant differences were found in results when comparing male and female subjects, all significant differences were found between medial and lateral menisci, with significant positive correlation between the different parameters. Conclusion:In cadaveric study, the posterior horn is the thickest and widest part of the meniscus in both medial and lateral menisci. There is also a strong positive correlation between the different parameters of the menisci (distance between anterior and posterior horns, the outer and inner circumference of the menisci). Regarding MRI study, it is concluded that, in agreement with the cadaveric study, the posterior horns of the menisci are the thickest and widest parts. There is also a strong positive correlation in thickness between different parts of the same meniscus, and the width between the different parts of the same meniscus. On the other hand, there were no significant differences in these parameters regarding the sex.

“…For calculating thickness of menisci researchers have used different methods and techniques in cadavers and living subjects. The common technique used was digital Vernier caliper to calculate the thickness of menisci that is measured with the help of a non-elastic cotton thread at three different levels as anterior, middle and posterior (1,2,5,6) .

Menisci is one of the most important structures of the knee joint. Owing to its importance in load sharing, shock absorption, joint stability, overall protection of articular cartilage various studies has been done on the morphometry of knee menisci by different researchers. Different parameters have been studied such as length of outer circumference of both menisci, difference between anterior horn and posterior horn of menisci, thickness and width of menisci. Such parameters have been reviewed in this article. It gives out a wider knowledge about the morphometric parameters of knee menisci and may guide the surgeon for the new treatment modalities in case of meniscal injuries.

Background: The meniscal cartilages are fibrous discs that are important for knee structures and have the ability to bear weight and stabilize joints. However, morphological and standard data for the meniscus are limited. Therefore, this work will compare anatomical and histological parameters of meniscal cartilages. The results will be important for the different measurements that are necessary for knee joint surgery. Materials and Methods: A total of 24 aged cadavers (12 males and 12 females) were included. Knee joints were dissected and the menisci were excised and labeled as medial or lateral, right or left, male or female. Then, the menisci were kept in 10% formalin solution. Morphological variations of the meniscal shapes were macroscopically categorized. Different measurements, including the distance between anterior and posterior horns, outer and inner circumferences, width (breadth), and thickness, were done using a digital Vernier caliper and recorded manually. Results: 48 medial menisci (MMi) cartilages were studied, they were 54.6% crescent-shaped, 34.6% V-shaped, and 10.8% U-shaped. 48 lateral menisci (LMi) cartilages were studied, 41.6% were crescent-shaped, 56.4% were C-shaped, and 2% were disc-shaped articular cartilage. Findings included differences in their lengths and thickness. Conclusion: The findings of this study were significant in providing new information on various morphological and morphometric parameters of the MMi and LMi in aged males and females, which are necessary to require more precise and comprehensive fundamental data that will be helpful for many specialists for better diagnostic and therapeutic approaches; aiming to restore normal joint conditions in senile people complaining of different meniscal pathologies.
