What is the knee joint of a person

Patella is located in the recess between the outer and inner ridges of the femur. In the contact area between the surface of all the bones of the knee coats the cartilage surface.

Between the main bones are cartilaginous horseshoe-shaped plate, called the meniscus. In the knee joint has two meniscus — external and internal, which redistribute the load by increasing and equalizing the contact area, and also function as shock absorbers.

The outer layer of the knee joint is a capsule that has synovial fluid. This fluid lubricates and nourishes the cartilage plate, providing a kind of lubricant.

Stabilize and move the bones relative to each other is performed by means of ligaments (muscles). Main ligaments: anterior and posterior — cruciate; inner and outer side. The tendons surrounding the kneecap and provide the extension (flexion) of the lower leg. Tendons are an integral part of the quadriceps muscle. Under the kneecap is a ligament that attaches it to the tibia bone.
