Knee Replacement Q & A

Who needs knee replacement surgery?

Several conditions can lead to the need for a knee replacement. These are some of the most common:

  • Osteoarthritis
  • Traumatic injury
  • Congenital deformity
  • Rheumatoid arthritis
  • Osteonecrosis (poor blood flow)

There are several different types of knee surgeries, and Dr. Farrell works with you to determine which approach is best suited for your needs.

What are the different types of knee replacements?

Your knee replacement surgery depends on the extent and type of damage within your joint.

Total knee replacement

The most common approach, this involves replacing the entire joint, including resurfacing the patella (kneecap) as well as the surfaces of your shin bone and thigh bone.

Partial knee replacement

This approach involves replacing only those components of your knee that are damaged. All healthy cartilage and bone are preserved.

Revision knee replacement

This method is used to correct joint damage after one or more previous knee replacement procedures. Some people with severe arthritis require revisions.

What types of materials are used in knee replacements?

There are varying materials and designs used in knee replacement surgeries, and Dr. Farrell will select the right implant for you.

Specific designs are chosen over others based on the extent of damage in your knee, your weight, your level of activity, and your gender. Likewise, the materials selected depend on your conditions and needs.

Materials often used in knee replacement procedures include titanium, metal alloys, high molecular weight polyethylene, or ceramic. It’s also not uncommon for your procedure to include more than one type of material.

What happens during total knee replacement?

Before surgery, you’ll undergo general anesthesia to ensure you don’t experience any pain. Dr. Farrell will begin by making the smallest possible incision to gain access to the joint. 

He will then work to remove damaged bone and cartilage, and prepare the bone tissue to receive the implant. A metal shell will be secured to the end of your thigh bone, or femur.

A different part of the new joint will be attached to your shin bone or tibia. If needed, a small plastic “button” will be added under your kneecap.

Dr. Farrell will determine whether your posterior cruciate ligament is healthy enough to remain in place, or if a polyethylene post offers better structural support for the rest of your new knee. In the final step, he will remove the surgical tools and close the incision.

After surgery, you’ll head to the recovery area for monitoring while the effects of your anesthesia wear off. The length of your hospital stay will depend on how well you respond to the surgery and your overall health.
