Throbbing pain 2 years after acl surgery

by Tony

Hi, I was curious if anyone has experienced the same problem as mine.
I had a ACL reconstructive surgery on my left knee 2 years ago. I am
experiencing the worse throbbing pain from the first day till this day.
The pain I am feeling is towards the inner side of the left patella. I feel pinching when my knee is in a 90 degree angle and if I stand for more than 20 minutes, my knee starts throbbing.

I have had cortisone shots in the last month and it seemed to help temporarily but the pain came back. I can't exercise and am limited to do any everyday tasks.

I have seen the doctor numerous time and can't seem to get any answers.

I also would like to mention that I did go to physio 3 times a week for the last couple of years and by all means have tried everything I could to improve this injury. I have had 11 operations on my right knee and it feels as good as new. I am by all means know slacker when comes to
rehabillating injuries. If anybody can give me any input, I would really appreciate it.

Thanks
