Did I tear knee ligaments?

About a year ago, I jumped over something (I do Parkour) with a lot of forward momentum. When I landed, I still had the momentum, so when I bent my knees to absorb the impact my knees went forward and I landed in a kneeling position. I then felt a sharp pain in my right knee (right where your thigh muscle would connect to the top of the knee) Then I felt fluid a rush of fluid above my knee. I put ice on it ASAP. I had just gotten out of a movie when I did this, so my legs where stiff. It healed after a while (2 months or so, I don't remember). I can walk with it and squat with it but I can’t kneel, do a Kip Up or anything that makes me fold my right knee all the way; which I did yesterday, so now it is hurt and swollen again. Is there some kind of permanent damage that will not let me kneel? Did I tear something important? It has been a year and it’s still not healed and it can recur?
