I definitely tore mine in my right knee its weird one day in like december i cased a jump and my right knee just hurt but I skied on it till the end of the day, then when I went to walk my knee was all stiff and i couldnt fully straighten it out. I didnt ski for a few weeks and its felt better but it still stiffens up sometimes.i feel fine when I ski but sometimes ill take a little spill and twist my leg a little and it hurts again and my leg locks up and feels unstable, and then ill try walking and it'll be stiff for a few hours but then it will be fine and I can walk normally again. Like right now it feels completely fine and when I ski it does too for the most part but sometimes it'll just stiffen up its weird, I should probably get it checked out but it doesn't affect me too much if i dont fall weird.
