3D printer helps with knee surgery


KETTERING, Ohio (WDTN) –  3D printers have become a real game changer in the medical field, having a big impact right here in the Miami Valley

One local man, Tedd Bommershine, knows first hand how the technology can make a difference in so many lives.

“Its just like a tooth ache,” said Boomershine about the pain he was having in his knees. “It never goes away. Its always there on your knees.”

That’s before he got two new knees six and a half months ago.

“I gained an inch in height, i’m not bowlegged anymore and I’ve got a different stride,” said Boomershine. “I walk better. I couldn’t be happier.”

The company, Conformis, takes a scan of the person’s knees and prints a customized replacement for them on a 3D printer.

“What’s nice about it is when you put these in it really just completely matches the exact contour of the patients bone,” said Dr. Don Dunaway, the orthopedic surgeon that did Boomershine’s surgery.

The technology makes a better fit for patients because not all knees are shaped the same.

Dr. Dunaway said, “Since its customized to their bone, I think the knee replacement feels more like a normal knee would feel as opposed to the off the shelves knees that have more of a mechanical feel to them.”

Its that custom fit and more natural feel that Dr. Dunaway thinks attracts people to this kind of knee replacement.

“I’m still the only guy in Dayton that does these. I’ve had patients come from Kentucky and from Indiana to have them done, because they wanted a custom knee,” he said.”The orthopedic industry is very progressive and very cutting edge, really across the board,. but this is taking it to the next level.”
