Knee Replacement Q&A

What is knee replacement surgery?

Your knee includes four key components: bones, tendons, ligaments, and cartilage. Damage to any one of these elements can cause chronic knee pain, stiffness, and poor mobility. While conservative treatments can help minimize pain and temporarily restore function to your knee, they aren’t always enough to provide lasting relief.

Knee replacement surgery removes damaged portions of your knee and replaces them with prosthetics. Dr. Kavanaugh and his team use the most advanced prosthetic and knee replacement technology by Arthrex®, Zimmer Biomet, and LimaCorporate Orthopaedic.

After a comprehensive evaluation that includes a physical exam, medical history review, and imaging tests, Dr. Kavanaugh diagnoses your condition and determines the appropriate type of knee replacement surgery for you.

What are the different types of knee replacement surgery?

There are several different types of knee replacement surgery that Dr. Kavanaugh and his team perform, such as:

Partial knee replacement

During partial knee replacement, Dr. Kavanaugh resurfaces only the damaged part of your knee. The procedure uses very small incisions, so patients can typically return home shortly after surgery and resume their normal activities quickly.

Total knee replacement

Total knee replacement is an arthroscopic procedure in which Dr. Kavanaugh replaces your entire joint through keyhole-sized incisions. He uses an arthroscope — a device with a small camera — to view the inside of your knee without fully opening the skin.

Kneecap replacement

Also called patellofemoral replacement, this procedure specifically replaces your kneecap. Only part of your knee requires resurfacing, so the risk of tissue damage is lower than with more invasive procedures.

Revision knee replacement

If any component of your prosthetic knee fails, revision replacement surgery can repair the damaged elements.

Who needs knee replacement surgery?

Knee replacement surgery is an effective procedure to relieve pain and restore knee function if you have:

Osteoarthritis

Osteoarthritis is, by far, the most common reason for knee replacement surgery. This wear-and-tear form of arthritis occurs when the flexible cartilage surrounding your joint begins to degrade.

Rheumatoid arthritis

As an autoimmune disease, rheumatoid arthritis causes chronic joint inflammation around your knee. The synovial membrane around your knee starts to thicken, ultimately leading to pain and stiffness.
