How Does Your Knee Work?

The knee is the largest joint in the body and is made up of the lower end of the thigh bone (femur), the upper end of the shin bone (tibia), and the knee cap (patella).

The surfaces where these three bones touch are covered with cartilage, a smooth substance that cushions the bones and allows them to move easily. Healthy cartilage lets you move your knee without pain when you walk, run or go up stairs.

All remaining surfaces of the knee are covered by a thin, smooth liner that releases a special fluid to lubricate the knee. This eliminates friction, or rubbing, almost completely in a healthy knee.

Normally, all of these components work in harmony. But disease or injury can disrupt this harmony, resulting in pain, muscle weakness and increased friction.

Osteoarthritis, the most common form of arthritis, is a condition that causes wear and tear to your joint cartilage. It develops after years of constant motion and pressure in the joints. As the cartilage continues to wear away, the joint becomes painful and difficult to move. If non-surgical treatment options, such as medication, physical therapy or lifestyle changes like losing weight, fail to provide relief, your surgeon may recommend total knee replacement surgery.

What is Total Knee Replacement Surgery?

Total knee replacement is a surgery to remove the damaged parts of your knee joint and replace them with new parts.

The word “replacement” may give the idea that your surgeon is removing the entire knee. But, they will only take out the damaged parts of your joint.

During knee replacement surgery, your surgeon will:

  • Put you under anesthesia.
  • Make a cut on the middle or side of your knee, so they can access your knee joint.
  • Remove the damaged parts of your bones and/or cartilage.
  • Replace those damaged parts with metal and plastic implants.

Knee Replacement Options

This type of surgery can have several benefits. It can:

  • Let your surgeon access your knee joint with less trauma to your thigh muscles.
  • Possibly limit your pain after surgery.
  • Possibly shorten your recovery time.

During this type of surgery, your surgeon will:

  1. Use special surgical tools to prepare your thigh and shin bones.
  2. Make a small cut (4 to 6 inches).
  3. Remove the damaged parts of your bones and/or cartilage.
  4. Place a standard knee replacement implant through the incision.

After this type of surgery, you may stay in the hospital from one to four days. This is similar to how long you may stay after traditional knee replacement surgery.1

Minimally invasive knee surgery is not right for all patients. Talk to your doctor to see if this is a knee replacement option for you.

Can Knee Replacement Technology Help Me?

To get the best results for your knee replacement surgery, accurate placement of each part is very important.

For many years, surgeons have used X-rays, surgical tools, and special techniques to plan surgeries. But now, advanced technologies for knee replacement are available to help your surgeon get your knee implant positioned just right.

You may have heard of robotics, robot-assisted knee surgery or computer-assisted knee surgery. Exactech’s Active Intelligence surgeons use a computer-assisted knee surgery technology. It is called ExactechGPS Guided Personalized Surgery. ExactechGPS has helped surgeons place knee replacement implants within 1 degree of the optimal position.3
