An ACL tear can end a career or a season in a split second.
Danny Hansen knows the feeling. He just had his latest ACL surgery. It's the third time he's torn up his knee playing basketball.
"In 2004, I had an ACL reconstruction and the same thing in 2007," he said.
Now a dad, Hansen wants to share his love of the sport with his son, Blake. Dr. Tony Nguyen says Hansen's prior surgeries failed because older techniques forced doctors to place new tissue in the wrong position, limiting the knee's ability to rotate.
To repair the ACL, Nguyen used a piece of tendon from Hansen's knee and a new technique.
"As a sports surgeon, it's a very big breakthrough," said Nguyen.
The approach allows surgeons to perfectly place the new tissue. That helps restore the natural anatomy of the knee.
While up to 25 percent of traditional reconstructions fail, Nguyen says the new technique and using his own tendon, the reported rupture rate is about four or five percent.
After Hansen's surgery, he says he's already feeling the difference.
"I'm walking better than I ever had before with my other surgeries," Hansen said.
He hopes for his son Blake's sake, this sugery will be his last.
