I was out on friday walking down the street and my knee popped 5 times like a set of black-kat firecrackers. I freaked out and fell down. I went to a specialist and he said i have Synovial Plica It's going to take a month to get back to normal according to him. It's suppose to happen to football players & sports people who bend their legs past 90 degreees. Apparently i'm only one more tear/irritation from having it removed. There's no point for pix. All you see is a knee a little swollen. Has anyone else had this? I can't squat for a month! Fawk!
