The meniscus is a small C-shaped cartilage that acts as a cushion in the knee joint. It protects the knee joint from wear and tear and helps to stabilise it.
There are 2 menisci that sit between the thigh bone (femur) and the shin bone (tibia). One is on the inside of the knee (medial) and the other one is on the outside (lateral).
A meniscus tear occurs when one of these pieces of cartilage in the knee is injured or torn.
Meniscus tear symptoms in the knee include:
A meniscus tear occurs when the knee is subjected to pressure and rotation or twisting while the foot is firmly planted. Even simple, everyday actions such as kneeling, squatting or lifting something heavy can result in a meniscus tear.
A torn meniscus is one of the most common knee injuries. People at any age are prone to this condition, especially those who engage in contact sports.
Those at particular risk for meniscus tear include:
A torn meniscus can cause long-term problems. Constant rubbing of the torn meniscus on the cartilage may cause the joint surface to become worn, leading to knee osteoarthritis.
