What is a torn meniscus?
There are 3 bones in the knee. These are the femur, tibia, and patella. The ends of those bones are covered with cartilage. This is a smooth material that cushions the bone and allows the joint to move easily without pain. The cartilage acts as a shock absorber. Between the bones of the knees are 2 crescent-shaped disks of connective tissue, called menisci. These also act as shock absorbers to cushion the lower part of the leg from the weight of the rest of the body.
