The meniscus is a fibrocartilage that separates the thigh bone (femur) from the shin bone (tibia). It is commonly referred to as cartilage. Each knee joint has a medial meniscus and a lateral meniscus. The meniscus assists with rotational stability and shock absorption with impact activities.
A meniscus injury can take place on any part of the meniscus. A meniscus injury can vary in severity from minor to severe. Having this injury will cause knee pain, swelling, tenderness, affect the movement in your knee and ultimately prevent normal function, activity or sport participation.
