ema's bad experience before ACL surgery !!!!

I was roller blading with my kids 7 weeks ago, loose control and felt, my right knee got twisted.
After a week I had an MRI done, i was told that my ACL was torn, and needed surgery, they sent me to pt for 3 weeks, came back to see the dr. and my knee still was so stiff, they put me on steroids for a week and sent me back to pt for 3 more weeks.
I went to see a 2nd opinion and the first day they injected cortisone in my knee and got a 2nd MRI done.
I have been doing my pt exercises at home 2 times a day. I see some improvement since the first two weeks, where I could not even go to the restroom without holding my self from the walls.
It's being very hard to get my full ROM.
Next week I will get the results from the new MRI, but I sitll worry about the stifness in my leg, the new Dr. also told me it was not ok : ( .
My first Dr told me that I could get osteoarthritis !!!!
Someone has gone through this before ...?????
