What is the function of the meniscus in the knee?

The meniscus functions primarily as a stabilizer and shock absorber within the knee joint. Comprised of two C-shaped cartilaginous structures (one on the medial side and one on the lateral side of the knee), the menisci play a crucial role in distributing weight across the knee joint and reducing the impact during activities such as walking, running, or jumping. This distribution helps protect the articular cartilage on the ends of the femur, tibia, and patella, thus allowing for smoother movements and reducing the risk of joint injuries.

By enhancing joint stability especially during activities that require quick directional changes, the meniscus also prevents excessive motion that could lead to injuries. This stabilizing function is essential for maintaining proper knee alignment and overall joint health.

Other options do not correctly describe the primary role of the meniscus. For instance, connecting muscles to bones is the role of tendons, while synovial fluid is produced by synovial membranes, not the meniscus. Joint hyperextension prevention is related more to ligaments and the overall structure of the knee rather than the specific function of the meniscus. Thus, the primary role of the meniscus as a shock absorber and stabilizer is pivotal in the functionality and health of the knee
