Even Olympic skier Lindsey Vonn has to deal with online criticism. Vonn - who tore her ACL during a race at the end of last month - took to social media to clap back at several users who were seemingly questioning the recent injury. "lol thanks doc," Vonn posted via X on Saturday, February 7, in response to a sports medicine doctor who was questioning the state of her injury. "My ACL was fully functioning until last Friday. Just because it seems impossible to you doesn't mean it's not possible. And yes, my ACL is 100% ruptured. Not 80% or 50%. It's 100% gone.
