The joints in the knee are the strongest in a human body, which is made up of thighbone- the lower end of the femur, shinbone- the upper end of tibia and kneecap- the patella. The end of all the three bones is covered with a smooth and slippery substance known as articular cartilage. This substance supports and protects the bones of the knee while you bend or straighten them.

The cartilage, which is between the thighbone and shinbone, commonly known as meniscus, act as the shock absorbers. This wedge-shaped cartilage is tough and rubbery and keeps the joint of the knee stable. The knee has a covering of thin lining, which is known as the synovial membrane. The synovial membrane provides fluid that lubricates the cartilage and helps in reducing the friction.
