Hi my name is keith and here is what happend. I was playing ice hockey and my skate got stuck and my knee twisted prety bad i felt a pop and i instantly droped to the ice. It was so bad that i couldent walk or put any preasur on it. so i went to the Dr. and had an MRI/cat done to see what the problem and after all was said and done they said i didnt kneed segury.. That was in febuary it is now june and my knee continues to cripple me even after the slighest twist.. i have not played sports or ran in 4 months why dose it keep buckeling?
