Customized Knee Resurfacing Creates a Perfect Fit

You’ve heard of custom suits and custom drapes. But how about custom knee implants – completely designed for you and guaranteed to be a perfect fit?

For patients with severe knee arthritis, this surgery is now available at Carolina Shoulder & Knee Specialists, a Lexington Medical Center physician practice.

Knees vary in size and shape. Even a person’s two knees may be different sizes. Traditionally, knee implants come in six to 10 standard sizes. Doctors select the one that fits the patient best during your surgery.

But for patients who have leg bones that are especially wide, narrow or odd-shaped, finding the perfect fit can be difficult.

“It can be like wearing your dad’s shoe. It’s a shoe, but it might not fit you correctly,” said Kevin Nahigian, MD, of Carolina Shoulder & Knee Specialists.

If a knee implant doesn’t fit properly, patients may experience pain or a knee that doesn’t feel natural.

Patients who choose customized knee resurfacing first have a diagnostic CT scan of their knee. The physician’s office sends the scan to ConforMIS, the company behind the technology. ConforMIS uses the scan to create a 3-D model of the knee and develop an individualized implant made of titanium cobalt chrome. The process takes about six weeks, and the implant is delivered to Lexington Medical Center a few days before surgery.

“The implants are designed to follow the shape and contour of each patient’s knee, which increases the potential for a more natural-feeling knee,” said Dr. Nahigian. “Customized implants also allow for optimal bone preservation.”

Patients can bear full weight on their knee on the day of surgery and go home from the hospital the next morning.

From exercising to playing with grandkids, the goal of customized knee resurfacing is to have patients back to enjoying an active lifestyle with the best results possible.
