not the best idea, but it can be done, i tore mine along with my minescus last January about 35 days into a 78 day season, i was sore for a week or so and i was limping around, but at that point i didn't even know i had tore it. i found out in august, i skied 104 days this year and had surgery a week ago yesterday. those of you who say its stupid to ski with a knee injure are just un informed, there are people with knee injuries all around you that they have elected not to fix. my dad tore his acl 15 years ago and still skis 25 days a year. its all about how you take care of it. i didn't push it to much this year and i was fine, i twisted it out a few times sure, but thats bound to happen skiing that much. i wore a light neoprene brace and that helps a ton. other than that ride low dins and enjoy it, do surgery when it is good for you. i cant walk for 3 weeks now, but i had a terrific season so im not complaining!
