Hi, i had 2 knee injuries in the past. It involved my miniskis or whatever is. Its the muscle that keeps the knee cap in place. I have had a injury a couple years ago, and my leg is still weak, can't put alot of weight on it, and still smaller then the other. I can walk fine and everything, i was just wondering if there is anyway i can make it stronger? Do i have to work it out or continue physical therapy?
