It might have been easier to retire, to say my knee couldn't handle it and let that be that. At the same time, the prospect of not being able to compete in gymnastics anymore was heartbreaking.

After 13 years of hard landings in gymnastics, one ski run had delivered the biggest injury of my career.

I missed being considered an athlete and having that competitive drive, and missed having something to work for every day. I'd taken two and a half years away from the sport and was out of shape. I wanted to get back to where I was in 2008.

I still can't believe I'm an Olympic athlete.

When I was 3 my parents put me in gymnastics because I was a bundle of energy and they just didn't know what to do with me! They put me in a Tots class and I just fell in love with it.

In some ways the ACL tear was a blessing. I had hesitated to return to elite gymnastics after the 2008 Olympics. I told myself I had already accomplished so much, and the road was just going to get harder if I continued.

I started from zero and went back to the basics in gymnastics.
