Knee Replacement Q&A

What is a knee replacement?

Knee replacement, also known as knee arthroplasty, is an orthopedic procedure that replaces damaged and worn-out parts of your knee with an implant (called a prosthesis). 

The prosthesis mimics the normal motion of your knee joint, which allows you to return to normal activities without pain or mobility restrictions.

When should I consider a knee replacement?

People get knee replacements for various reasons, but arthritis is the leading cause. The most common form of arthritis is osteoarthritis, a condition that often affects weight-bearing joints like the knees.

You may also need a knee replacement if you have severe and persistent pain from a knee injury, such as a fracture, or a deformity.

What are the different types of knee replacements?

There are various approaches to knee replacement surgery. Dr. Melander carefully evaluates your knee and recommends the best procedure for you.

Traditional knee replacement

Traditional knee replacement surgery uses a large incision — 8-10 inches long — in the center of your knee. Through this incision, Dr. Melander removes the damaged areas of your knee and positions a prosthesis.

Minimally invasive knee replacement

Minimally invasive knee replacement is similar to traditional knee replacement surgery, but with a smaller incision and less cutting of the healthy tissue around your knee. Dr. Melander specializes in minimally invasive surgery and uses this approach whenever possible.

Dr. Melander uses the highest-quality implants and most advanced techniques available, including the Persona® personalized knee system by Zimmer Biomet. The personalized knee system provides optimal fit and function, leading to greater success in knee replacements.

What is recovery like after a knee replacement?

Whether you undergo a traditional or a minimally invasive knee replacement, you’ll probably need to stay in the hospital for 1-4 days after your procedure. Because minimally invasive knee replacements require less cutting, they usually involve a faster and easier recovery.

As with any type of orthopedic surgery, a period of physical therapy and rehabilitation is essential for a successful recovery. Dr. Melander will recommend specific exercises to perform at home so you can increase your range of motion and regain strength.
