Form and Function of the Menisci of the Knee

Understanding Medial Menisci

The medial menisci refer to the crescent-shaped cartilage discs found on the inner side of the knees. Unlike their counterparts, the lateral menisci, they have a narrower front section. What sets them apart is their insertion sites, which are relatively larger than those of the lateral menisci. The medial menisci play a crucial role in connecting the femur to the deep medial collateral ligament and the lateral meniscus to the transverse ligament, forming a cohesive network around the knee joint.


The Role of Lateral Menisci in Knee Health

Located on the outer sides of the knees, the lateral menisci play a crucial role in maintaining knee stability and function. In contrast to the medial meniscus, the lateral menisci have a more circular shape, resembling a crescent. These structures are securely attached to the tibia, with both horns connecting to it.

At the front of the knee, the lateral meniscus attaches near the anterior cruciate ligament (ACL), a key ligament responsible for knee stability. Towards the back, it is connected to the posterior horn of the medial meniscus. Additionally, the lateral meniscus is loosely attached to the capsular ligament, which provides added strength and support to the knee joint.

Understanding the significance of the lateral menisci is essential for maintaining optimal knee health. These structures help distribute weight and absorb shock during movement, preventing excessive stress on the knee joint. Proper care and attention to the lateral menisci can contribute to overall knee stability and reduce the risk of injuries.
