Hi, I am a 19 year old girl who play netball. 4 years ago I suffered from partially ACL tore. After that my knee start to have that cracking sound whenever I bend down or I try to bring my knee toward my chest. It's painless most of the time, but at times it hurt abit. When I sprint, my leg seems to give way, I felt week. And everytime after training, I felt that both side of my knee swollen. A little bit pain. I have also injury my ankle and the doctor say one of my ankle bone near my side of metal tarsal has broken.
