Hey Ross, I am Hernan, I am a bilat (hi Hernan!), but not a simultaneous one like you crazy guys. My right has always been a little behind my left. It's curious, since my right was much better than my left before the surgeries, but it was done last.
Maybe the fact that my left was done first, went through two cycles of PT and needed to support the right made it scared straight.
My right is still not quite as strong as the left at two years, but is more than strong enough for anything I do - kicking large punching bags and make them move, soccer, lifting weights, etc. It's a relative thing, since the left feels so good and the right feels so good minus 0.0000000000000001.
I've been working on it - balancing, juggling, working out with bands on my ankles, ankle weights, etc. It's not painful, sore, or weak, just a little bit behind for the stuff I'm putting it through. It may be a just a psychological thing (seeing as it's equally capable as the other every time I've "tested' it), and I may be turning it into the hip Hulk by all the stuff I'm doing, but it keeps me off the streets.
So it does catch up, everyone is different and it is not unusual or even unexpected to have one be better off at first than the other.
