“…[8] The normal meniscus demonstrates low signal on both T1 and T2 weighted images. Some studies report on the morphometric parameters of the cadaveric menisci, [9][10][11] but the in vivo studies are scarce. Since the menisci perform important mechanical functions, they are exposed to injury.…”

“…The measurements were done based on the methods described by Murlimanju BV et al [17] The peripheral lengths of the menisci were measured with the non-elastic cotton thread. The thread was placed along the periphery of the meniscus and held in place with metallic pins.…”

“…[17] Implications for future study would involve studying the radius of curvature or measurement of volume of the meniscus with software like scion image analyzer. We believe that our study will provide extra edge to the literature concerning the surgical procedures and arthroscopy of the knee joint and will be of help to orthopaedic surgeons and morphologists.…”

ABSTRACT:The morphometrical data related to the menisci of the adults have been reported by few authors but data specific to the population of East Goadavari region have not been reported. The aims of the present study were to analyse the external circumference thickness, the width, peripheral and inner border lengths, and the distance between anterior and posterior horns of the menisci and to compare them with those which are available in the literature. The menisci from 100 knee joints of the formalin fixed cadavers which were obtained from the Anatomy department of Rangaraya Medical College, Kakinada and Konaseema Institute of Medical Sciences and Research Foundation, Amalapuram were analysed. The cadavers which had musculoskeletal anomalies were excluded from the study. A vernier calliper of 0.02 mm accuracy and a non-elastic cotton thread were used for the morphometry. After comparing the meniscal dimensions of the present study with the other available literature, we established that there are some morphological differences of meniscus in this set of population.

“…It affects 4% to 5% of the patient population, with a much higher incidence, upto 13% in the Asian patient population. Cadaver studies have reported the prevalence of lateral discoid meniscus to be 0 and 7% whereas arthoscopic studies have demonstrated ranges from 0.4% to 16.6%, but the racial differences do exist among the incidence rates [13][14][15]. Normal variants of the meniscus are relatively uncommon and are frequently asymptomatic, although there is greater propensity for discoid menisci to tear.…”

Background: The menisci of knee joint are important functional units able to improve joint congruence and load distribution thereby reducing the stress on the knee joint, a function that is considered primordial to protect the articular cartilage and prevent osteoarthritis. Variations of form and in particular of thickness and width of menisci can determine the possibility and kind of injury. The study of morphology of menisci of the knee joint will provide support to meniscal anatomy which is necessary for various surgical procedures and also for arthroscopy of the knee joint. The knowledge of exact size and shape is essential for meniscal transplantation in meniscal injuries. Materials and Methods: The study is done on 50 menisci (32 right and 18 left sides) of adult cadavers preserved with formaldehyde solution obtained from department of Anatomy, MMC&RI. To measure the length of each menisci, a cotton thread is placed across the outer edge of the meniscus from the apex of the anterior horn to the apex of the posterior horn. Next the thread length is measured using vernier calipers. Width is measured at three points-anterior third, middle third and posterior third. From each point, distance between outer edge to inner edge is measured using vernier calipers. The thickness of the meniscus is also measured at three points-anterior third, middle third and posterior third. The data was analysed using the student t-test for independent samples. Results: The individual analysis of each meniscus showed that posterior third of medial meniscus was the widest part (16.68±0.60mm) (p<0.05) followed by middle third (12.09±0.22mm) and anterior third (8.88±0.19mm). Related to the thickness of outer circumference of meniscus, posterior third (5.90±0.12mm) of medial meniscus was the thickest part followed by anterior third (5.58±0.18mm) and middle third(5.28±0.12mm). However, in the lateral menisci, middle third was the thickest part (p<0.05) (table I). In the present study, the peripheral length of medial meniscus (10.38±0.33cm) was significantly more than the lateral meniscus (9.61±0.2cm). Discoid medial and lateral menisci were not observed in the present study (0%). Conclusion: The result of this study showed that there is an important relationship between the morphometric data of the menisci and the data found in the clinic, which would explain the incidence of injuries in specific points of each meniscus.
