ok so i was at the skate park and i was t wiping over the (nothing big) and the one time i went for it i jumped of and i was coming down and my right leg was still over my scooter and i landed on my scooter and the scooter took of and my knee bent to the side and it cracked and popped and after that i couldn�t walk for like 3 days.......so like about a week later i thought it was all better so i went back to the skate park and i was just airing the spine and i jumped off and tried to run down the ramp and pop my knee popped out of place again and it heart so bad for like 15 min but it was not as bad as the first time. i think on inner side of my knee i tore a muscle big time because my knee can just pop out any time it wants and it kills so bad.......the whole point im posting this is to see if any one has done this and how long dose it last or dose it ever go away.
