Part 2 of a four-part series
Two winters ago, Lynnette Bellin tore her knee while skiing with her 5-year-old daughter.
"I felt the trademark pop ... and instantly knew I had injured my knee," she says.
But within a year, she was back to her athletic life.
"Recently in one week, I skied, ran, kayaked, standup paddle-boarded, swam and hiked. At the end of that week, I looked back in awe from where I have come from," she says.
Bellin healed quickly after receiving a tendon from a cadaver, which helped to repair her torn ACL.
