i was back @ work 3 months post-op, as a nurse, so yeah, you'll do fine once you go to uni!
Good luck, anything you want to know, shoot! It's always said as a major surgery with a hard and painfull recovery, in my case I can honestly say it was a lot less painfull as expected, but yet hard. Regaining muscle strenght is the hardest part of the whole post-op blablabla. I can do everything, run like 20K a week, I am acompetitive badmintonplayer and combine 2 jobs on ER/ambulance. Screws are still in my knee, no problems with them. Surgery was 10 years ago, I was 25.
