Introduction: The knee is the largest synovial joint in our body. Among the different ligaments of knee joint, menisci are a pair of fibro cartilaginous plates situated within the knee joint on the tibial condyles. Lubrication, proprioception, joint stabilization, load transmission are the major functions of the knee meniscus. Variations of form and in particular of thickness and width of menisci can determine the possibility and the kind of injury. Meniscal replacement is required in cases of severe loss of meniscal issue or degenerated. The correct size of the allograft is likely to be critical for successful healing and functionality.
Objective: 1) To determine the thickness, width and circumference of the menisci of human knee joint 2) To measure the distance between anterior and posterior horn of the menisci of human knee joint.
Material and Methods: 50 menisci of 25 knees of the formalin fixed adult human cadavers were dissected and studied in the department of anatomy, JSS Medical College, Mysore. The knee joints included 13 right and 12 left specimens. A slide caliper is used to measure the distance between anterior horn and posterior horn of the menisci and to measure the thickness and width in anterior 1/3rd, middle1/3rd and posterior 1/3rd of the menisci. Outer circumference and inner circumference is measured by non elastic cotton thread.
Results: The peripheral length and inner border length of medial meniscus was more than that of the lateral meniscus. Posterior third of the medial and lateral menisci was the thickest part compared to anterior and middle thirds. The distance between the anterior and posterior horns of the medial meniscus was significantly more than the lateral meniscus. The individual analysis of each meniscus showed that the posterior third was the widest part than the anterior and middle thirds.
