When Is Knee Surgery Not Appropriate?

Even though knee surgery may be an effective way to minimize or eliminate knee pain, your doctor may decide that knee replacement surgery is not appropriate for you. Some reasons could include:

  • You have an infection or a history of infection
  • You don’t have enough bone, or the bone is not strong enough to support a new knee
  • You have injured nerves in your knee area
  • You have injured or nonfunctional knee muscles
  • Your knee is severely unstable
  • Your bones are not fully grown or developed
  • You have noticeable bone loss or a severe decrease in bone mass (osteoporosis)
  • Your knee joint has been previously fused and is stable, functional, and painless
  • You have rheumatoid arthritis and active/history of skin lesions (due to increased risk of infection)

What Is Total Knee Replacement?

A total knee replacement is usually considered when the surfaces on both sides of the bones, as well as the underside of the patella, are significantly damaged.

In total knee replacement surgery, the surface of the thighbone (femur) is replaced with a contoured metal component designed to fit the curve of your bone.

What Is The Right Knee Surgery For Me?

Knee replacements have been highly successful for more than 30 years. According to the US National Institutes of Health, 9 out of 10 patients who undergo the procedure report improved pain relief, knee function, and overall health-related quality of life.1

If the surfaces on both sides of the bones, as well as the underside of the patella, are significantly damaged, a total knee replacement is usually considered.

What Is Patello-Femoral Knee Replacement?

Your knee joint is comprised of three bones. Your thighbone (femur) sits on top of your shinbone (tibia). When you bend or straighten your knee, the rounded end of your thighbone rolls and glides across the relatively flat upper surface of your shinbone. The third bone is often called the kneecap (patella), which is attached to the muscles, allowing you to straighten your knee.

What Are The Risks Of Knee Surgery?

Knee replacements have been highly successful for more than 30 years. According to the US National Institutes of Health, 9 out of 10 patients who undergo the procedure report improved pain relief, knee function, and overall health-related quality of life.1 And because medicine is always developing new materials and procedures, the results continue to get better.

Treating Knee Pain With Surgery

Most people will not need knee surgery, but, in many cases, surgery may be effective in minimizing or eliminating your knee pain when other treatment methods have failed. Many advances have been made, allowing for surgical procedures that are much less invasive. With smaller incisions requiring less cutting of the skin, tissue, and key muscles, such minimally invasive procedures are revolutionizing the way patients experience and recover from surgery, often resulting in less postoperative pain, a faster recovery period, and a shorter hospital stay.

Questions To Ask When Considering Knee Surgery

Here are some questions that may be helpful to ask your doctor when considering knee surgery. We suggest you print this list and take it with you to your appointment. It’s also a good idea to keep a record of your knee pain to share with your doctor at the same time.

Biomaterials and more

As you’d expect, orthopedic implants are very “high tech.” Their designs can be quite complex, and the materials used to make them, called biomaterials, are highly developed. Examples of biomaterials include titanium, cobalt-chrome, polyethylene, and Trabecular Metal™ Material.

In the United States, the FDA requires extensive testing before a new material may be used in an orthopedic implant.

How Is Knee Replacement Surgery Performed?

Knee replacement surgery is the same idea as having most things fixed—worn parts are taken out, and new parts are installed in their places. In knee surgery, the damaged portions of the knee bones are removed, and the knee is resurfaced with metal and plastic implants.

Caring For A Loved One After Replacement Surgery

Caregivers play an essential role in the lives of people having joint replacement surgery. As a caregiver, you can facilitate conversations with the doctor, help make decisions, and lend a hand during the recuperation period. Because caring for someone who has had joint replacement surgery can be taxing on you, it’s important that you don’t forget to take care of yourself during this time, too.
