Hi! Dislocated left knee about 1 1/2 years ago. (lower part of the legg was twisted outwards from the knee, very visible dislocation. I locked it back but couldn t move so called ambulance.) Now there is a small lump on the left side of my knee, so when I bend my knee, the ligament moves over it and that causes visible motion when i look at it. It is not very painful though. But when I sleep, i have to put blanked between my knees, because the inside is a little painful. It has been like that since last year september. It doesn t seem to fade, neither it seems to grow worse. Any ideas? Thank you
