Knee Replacement Q & A

What is knee replacement surgery?

Knee replacement surgery replaces a damaged knee joint with artificial parts. Also called knee arthroplasty, this procedure replaces the damaged or worn surfaces of your knee with implants to relieve pain and increase mobility.

Dr. Karas specializes in rapid recovery techniques, including minimally invasive knee replacement, so you can return to the activities you love as soon as possible.

What is minimally invasive knee replacement surgery?

Traditional knee replacement surgery involves making a long, vertical incision on the center of your knee to access the joint. The minimally invasive procedure uses a smaller incision, about half as long, and less-invasive techniques to reach the joint.

By reducing the incision and damage to healthy tissue, minimally invasive knee replacement offers many benefits, including:

  • Less pain
  • Reduced scarring
  • Shorter hospital stay
  • Faster recovery time

Most of Dr. Karas’ patients spend only one day in the hospital after a minimally invasive knee replacement. The minimally invasive technique isn’t appropriate for every patient, but Dr. Karas thoroughly evaluates your condition to determine the best procedure for you.

Why would I need a knee replacement?

Knee pain and limited mobility from osteoarthritis are the most common reasons adults receive knee replacements.

Other medical conditions that can damage your knee joint to the point of requiring replacement include:

  • Rheumatoid arthritis
  • Osteonecrosis (bone death from lack of blood)
  • Bone tumor in the knee joint
  • Fracture or injury to the knee joint

If only one side of your knee is damaged, Dr. Karas may perform partial knee replacement surgery instead of a total replacement. This involves replacing tissue on only one side of the joint.

What should I expect from knee replacement surgery?

First, Dr. Karas spends time discussing your concerns, fears, and the expected outcome of knee replacement surgery so you feel comfortable going into the procedure.

Dr. Karas performs knee replacement procedures while you’re under general or spinal anesthesia. Once you’re asleep and numb, he makes a small incision on your knee and removes damaged portions of your bones. Then, he replaces the bone with metal implants and a plastic spacer and closes the incision.

The whole procedure typically lasts a couple of hours. Afterward, Dr. Karas provides you with instructions on how to make your recovery as safe and quick as possible. You should be able to go home the next day.
