The meniscus is the cartilage shock absorber between the femur and the tibia.  Problems with the meniscus can range from mild wear and tear to thinning of the cartilage to a tear from injury, usually twisting.  Symptoms can range from mild to the other extreme, of instability or giving way of the knee and locking.  Physical examination and imaging give us a far better idea of the extent of damage and help us plan a course of treatment.
