I just got an MRI, but I don't really understand all the stuff it says. I'm 21 in the Army, been in since I was 18. Knee started hurting about 2 years ago. Went to physical therapy for about 6 months, but it didn't help, and they just now did an MRI. It says I have a cyst, PCL grossly intact, some damage to ACL and meniscus (it goes into a lot more detail on the paper).
