Knotted--are you a PT? My ortho didn't refer me to pt; he just gave me a big brace and a little booklet. The exercises in the booklet involved ankle weights and not much else. I didn't find the brace or the ankle weight exercises particularly useful (the exercises were very minimal, and seemed designed for people who were either not very active to begin with or coming back from surgery), and at the time I was only running, so I didn't have too much trouble w/the ACL. as a consequence, I slacked off on the exercises (and quit wearing the brace).

Since, at the time, I had only gone to see the ortho to find out why my knee kept "going out" when I walked, and he didn't seem to think that it was a problem for me to keep running if it wasn't bothering me during that activity, and since I wasn't cycling at the time, we mutually decided not to pursueit farther. (Plus, he probably assumed I'd continue with my exercises.) Now I wish I'd been a little more proactive.

About two weeks ago I decided to do some weight training to see if it would help. I started doing hamstring curls, quad extensions, and squats. Are you saying that the hamstring curls are the best thing for the ACL? Should I concentrate mainly on those? Are the quad extensions or squats detrimental?

Also, should I position my seat so that I am using more of my hamstrings, or less?

It is interesting to note that the the hamstring on the "bad" leg is noticeably smaller than on the "good" leg...Could this be related?
