Meniscus are two pieces of cartilage inside your knee. They lie between your thighbone (femur) and shinbone (tibia). Meniscus act like shock absorbers for your knee, providing cushioning for your bones and knee joint. Meniscus also increases surface area of contact between femur and tibia thus preventing weight to be concentrated on a small area.
People who had tear in meniscus often feel like something has popped in their knee at the time of the injury.
low grade meniscus tear can be treated conservatively with medication and physiotherapy. High grade tear need arthroscopic repair using all inside suture technique.
