Rehab for Partial ACL Tear

Thanks for the responses guys. I wasn’t really inquiring for myself, as I know lots of these things already from my own experiences. I was sort of playing devil’s advocate for the sake of getting lots of good info into this thread.
I’ve had surgeries on both knees, ACL replacement and meniscus repair/removal on the right, recently I had meniscus removal on my left and during the surgery the surgeon discovered that my ACL was torn but had scarred on to another ligament. He thought he had felt instability on the test where they pull forward on your shin, but the MRI hadn’t shown much.
I and the surgeon who recently did my left knee are of the opinion that the surgeon who did my right knee didn’t do a very good job. So, I was playing devil’s advocate to get as much info as possible, since knowledge is good :)!
Thank you for the detailed responses!
