ACL reconstruction has become a relatively normal procedure with athletes jumping back into play within weeks of surgery. In a study of reconstructed knees of recreational runners, while the ACL reconstruction corrected the anterior displacement of the tibia, it was found that the knees were more externally rotated and adducted. Knowing this, part of the standard rehabilitation should be modified to include not only terminal knee extension and quad strengthening but ensuring proper alignment in terms of internal rotation and abduction. If you are going into an ACL reconstruction surgery, strengthen your leg as much as possible before hand and while going through rehab post-op, make sure your rotators and glutes are firing properly and have the right level of resting tension.
