Background: Knee joint is the largest synovial joints in the body It is a compound joint that includes two condylar joints between the femur and the tibia, the former being partly divided by menisci. The menisci (formerly called semilunar cartilages) of the knee lie within the knee joint between the femur and tibia and somewhat adapt the tibial and femoral condyles to each other. The menisci performing important mechanical functions, such as supporting body weight, shock absorption, stabilization and rotational facilitation.1 The meniscus plays an important role in load sharing, shock absorption, joint stability, joint nutrition and overall protection of articular cartilage.2 Objectives:To study the morphometric parameters of lateral menisci of both thekneejoints. Materials and Methods: :Thestudywasconductedon30kneejointsof15formalin fixed cadavers of unknown sex and measured the Inner circumference , outer circumference and widthof the lateral meniscus of both the knee withthe helpof digital caliper Result:Total mean length for both sides taken together was 4.38±0.9cm. the minimum and maximum length of the outer circumference in right lateral menisci 6.6and 6.9 cm, and in left lateral menisci was 6.6 and 6.9 cm and the total mean Length of both the sides taken together was also 6.6 and 6.9 cm respectively. The mean length of the outer circumference was 6.76±0.9cm for right lateral meniscus, 6.76±0.9 cm for left lateral meniscus and the total mean length taken for both sides was 6.76±0.9 cm. The total mean width (left and right) of lateral meniscus of anterior one third was 0.58; Middle one third was 0.82 and at Posterior one third was 0.91. The average mean width of all lateral menisci of anterior one third was 0.58±0.5, Middle one third was 0.82±0.9 and at posterior one third was 0.91±0.7 indicating that posterior part is widest segment followed by middle and anterior segments. However by using Student t-test, no significant difference in width between of three points discussed was observed Conclusion:This study provides the valuable information at the time of totalkneereplacement andalsoprovides theguidanceto theorthopedicians.
