ABSTRACT:

Background: The Medial and Lateral Menisci have very important roles in knee joint stability, functioning and dynamic loading and are thus important in maintaining proper joint health and stability.

Purpose: To estimate the incidence of various shapes of the Lateral and Medial Menisci which can throw light on itsclinical significance on ligament injuries of knee joint.

Results: 50% 0f the Medial Menisci were crescent- shaped,37% were sided V-shaped and the remaining 13% were sided U-shaped. 72% of the Lateral Menisci were found to be C-shaped and 26% were crescent-shaped. One partial discoid lateral meniscus (2%) was observed.

Conclusion: The various morphological variants of Menisci determined in the study revealed that most common subgroup of the Medial Meniscus was crescentic type and that of Lateral Menisci was C shaped. A single specimen of partial Discoid Lateral Meniscus was observed which is of rare occurrence.

Implications: The present study contributes to proper understanding of anatomy of both Medial and Lateral Menisci which can be helpful in planning various surgical procedures including meniscal transplantation. This knowledgealso helps in understanding degenerative diseases affecting knee joint Menisci. Discoid Lateral Meniscus, a rare anomaly which was reported in the present study is clinically important because of its higher incidence of meniscal tears.

Key words:  Medial Meniscus, Lateral Meniscus, Crescentic, Sided V, Sided U, Knee Joints.
