Cannot give any definitive answers as obviously differs from person to person. All the surgeons in the acute hospital I worked in had different protocols regarding their ACLs (one instructs patients are NWB for 4 weeks whereas another gets them FWB from first day post-op). In most ACL reconstructions I've seen, and the conservatively managed ones who weren't operated on, I never stressed that they perform exercises on both sides (unless it was unintentional) as generally found that the affected limb would be considerably weaker and require much more rehab to get back to the uninjured level.

As bikelet said^, rehab is important. What specific rehab protocol are you following? The surgeons where we work have differing rehab protocols, also depending on what type of graft it was. Generally most that I've seen have said to avoid any open chain activity and work hard on proprioception and hamstrings strength. As a rule of thumb, they said to avoid full return to sports until 12-18 months post-op. Specifically 16-18 if contact sports, if I remember correctly.

P.S. how far post-injury are you? perhaps you're being a little hard on yourself. I have treated an 18 year old whose MRI showed complete ACL rupture who had superb core stability and muscle strength and on examination was completely asymptomatic after a few sessions "prehab." He was continuing with all sports aside from football as he had been advised against this (by myself and the surgeon) but he was continuing to run considerable distance every night (although on the advice to avoid sharp turns/fast changes of direction).

I would say you probably need to give it more time before you judge whether or not you're "back to normal." If you're working hard at your exercises and core stability, you will reap the rewards.
