The common name for the cartilage located in your knee is meniscus. The meniscus serves as a cushion between the femur and tibia, providing stability, distributing weight, and absorbing shock during activities like walking or running. Each knee contains two menisci, the medial and lateral, which are vital for maintaining proper knee function and overall joint health. Damage to the meniscus can lead to pain and increased risk for arthritis, making its protection and care important for active individuals.
