How Is The Knee Put Together?

The shin bone, the knee cap, and the thigh bone are the main components of the knee. In medical terminology, these are called the tibia, the patella, and the femur. Your knee is in almost constant use, and it is the largest joint in your body. For these reasons, you are highly likely to injure your knee or experience some wear and tear at some point in your life.

The bones of the knee are held together and stabilized by ligaments. These are called the medial and lateral collateral ligaments and the anterior and posterior cruciate ligaments.

Another important part of the knee is the thigh muscle. If the thigh muscles are strong, the knee will also be strong and more stable.

Articular cartilage is a substance that pads the knee and keeps the bones from grinding against each other. This smooth material forms a cushion that allows the parts of the knee to move freely. Additionally, fibrous semicircular rings of cartilage tissue called the medial and lateral menisci absorb shock and stabilize the knee.

Over all of this structure lies the synovial membrane. This is a smooth, thin tissue that lines the interior surfaces of healthy knees. It produces a lubricant that keeps everything running smoothly and painlessly in healthy knees.

All of these parts should work well together and give you a lifetime of painless service. However, because the knee is the most used and most often injured joint in the body, this is often not the case. An injury or illness such as arthritis can throw this delicate balance off. This can cause you loss of mobility and strength, as well as a great deal of pain.

Generally speaking, knee replacement surgery is done in patients ranging in age from sixty to eighty. However, this is not set in stone. Your orthopedic surgeon will look at your disability and your level of pain to determine whether or not you would be a good candidate for total knee replacement surgery. This surgery has been successful in people of all ages - ranging from very young teens with juvenile arthritis, to the very elderly with degenerative arthritis. - 17269
