PEARL CITY (KHNL) -- Prosthetic limbs have been around for a long time, but advances in technology are making life easier for many amputees.
Katie Vroucher lost her leg in a car accident when she was 16.
Today, she can easily walk down stairs, wear high heels, even hike Diamond Head. All thanks to her new knee.
"It's just amazing, it's just absolutely amazing what its able to do."
The new leg is programmed to her stride.
"It has a chip in it, I have to plug it in at night. It's crazy, it's like a robot."
After being on a waiting list for two years, Katie almost didn't get the leg.
"Once I got up to the list and I was able to do it, the health insurance was like, sorry, we can only pay this much --and my family wanted to do it so much, but they just couldn't."
When she got married, her new insurance picked up the bill.
"I mean that's the only reason that I have the leg that I have today, is because of Tricare and the great insurance through the military."
But it's not without sacrifice. Katie's husband returned last week from a 15-month deployment to Iraq.
"Having to deal with my husband in Iraq was worse than dealing with the rehab and recovery for me ."
Through it all, she has an incredible outlook on life. Katie and her husband made the best out of a difficult situation.
"And we have a joke. He says, well you know what -- If I do get injured by an I.E.D., I married the best person for it.' I was like, yeah I can teach you how to walk again, its not a problem. He's like yeah, its not a problem, you sure could," she said through a smile.
