I'm about 13 week post ACL reconstruction. I tore my ACL/lateral meniscus and fractured my patella on 10 Oct and got the surgery on 17 Nov.
I've been logging my recovery here, starting right about 2 weeks post surgery.
I didn't get to start physical therapy until a month after surgery due to insurance silliness, but was still training as much as I could. If you check out the log you can see some of my work arounds, but basically there is still a LOT you can do with a recovering ACL...as long as you don't mind disobeying doctors orders and putting yourself in the path of a lot of potential danger. One of the biggest things I did was still train the good leg as hard as possible while I was recovering.
I can go into some more detail if you'd like.
