The Function and Anatomy of the Knee

By Dr. Stefan Tarlow

The Way Knees Work

A joint is made of two or more bones connected by strong bands called ligament. Our largest joints are our knees. The knee is essentially made up of three parts:

The patella, which is better-known as the kneecap.

2. The shin bone (tibia).

The tibia, which is the upper end of the shin bone.

Additionally, the quadriceps (long muscles on the front of the thigh) strengthen the knee.

The knee is cushioned by articular cartilage which covers the bone surfaces where they come in contact with each other.

Additionally, the knee mechanism is lubricated by fluid that is generated by the synovial membrane. This thin, smooth tissue liner covers the remainder of surfaces within the knee. It prevents the end of the joint bones from rubbing.

How Does Knee Pain Happen?

Sometimes cartilage just gets worn out. When it does, the bones rub against each other and cause friction, swelling, and pain.

This situation is usually caused by osteoarthritis. This is a condition in which there has been knee injury or trauma. When there is no cartilage, there is nothing to absorb the shock between the bones that make up the joint. When this happens, the bones become stressed and painful.

A Few Ways to Treat Knee Pain

It is possible to treat knee pain with both no steroidal and steroidal anti-inflammatories. You can also benefit from cortisone injections, physical therapy, and bracing. However, if you have already given these methods a try and still have not found relief, it is not worth limiting your activities and living with pain. You may want to turn to surgery.

Knee replacement surgery was done for the first time in 1968, and it has been a popular solution to knee pain ever since. It is typically successful and results in the relief of pain and the restoration of knee function. More than a quarter of a million Americans undergo knee replacement surgery every year.
