Who's torn their ACL? How do you know? Advice?
About 5 weeks ago I injured my knee during an impromptu sparring session. I caught a guy with a kick from a bad position and thought I had just hyperextended it, which I have done more times than I can count. It did swell up pretty badly and I had some problems walking normally for a few days. I iced it regularly and took anti inflammatories.
Several weeks later, it's still not 100% but I am moving on it pretty well. I still have what would appear to be swelling in the front near the cap (possibly fluid?) and it is very painful to sit in a kneeling position. Yesterday I did a little hop motion and when I landed it went out on me and I had to go down onto one knee. It didn't swell up and it was back to it's normal slightly painful but usable self after about 10 minutes. There is also a slight pain on the outside of the knee.
Anybody have any experience with something like this? Does it sound like it's just a really bad hyperextension? Or did I possibly tear something this time? How can I tell?
