Anatomy of the Knee
The knee is a vulnerable joint. It bears a lot of stress from everyday activities
such as lifting and kneeling. It also bears stress from high-impact activities such
as jogging and aerobics.
The knee is formed by the following parts:
Tibia. Shin bone or larger bone of the lower leg
Fibula. Smaller of the 2 lower leg bones
Femur. Thighbone or upper leg bone
Each bone end is covered with a layer of cartilage that absorbs shock and protects
the knee. Basically, the knee is 2 long leg bones held together by muscles, ligaments,
There are 2 groups of muscles involved in the knee:
Tendons are tough cords of tissue that connect muscles to bones. Ligaments are elastic
bands of tissue that connect bone to bone. Some ligaments on the knee provide stability
and protection of the joints. Other ligaments limit forward and backward movement
of the tibia or shin bone.
