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.

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 as quick as possible. You should be able to go home the next day.
