I did my ACL in about 20 years ago and that forced me to favor my left leg, which was always stronger anyway.
My left leg is much bigger than my right, (will tape measure it tonight). Since I've started cycling my weak right leg has improved a lot.
I also carry my heavy briefcase on the right side, and can't break the habit of switching.
My lower left back aches, probably form compensating. for the knee as well.
I think the only thing you can do, is stretch a lot, share the work load and when you can see a muslce is weaker than it's opposite is to work it a little bit harder, and adopt good posture at all times.
Swimming is a pretty good sport as well as cycling for sharing the workload.
I'm also left handed/footed, and I notice the effects of living in a right handers world on my balance as well.
For example:
Walking through the train station turnstiles the tickets must always be placed on the right side, which my body hates.
Do you favor one side of your body when walking? sitting? Using the PC? sleeping? People's faces are even differnet from left profile to right from always sleeping on one cheek on their pillows....
Tits are another story!!!!
