This is my logic, please feel free to correct me if I'm wrong, in fact, I insist you do so.

My logic is that if I do LL on both the femur and tibia, 4cm in each, my femur to tibia length ratio and proportions will remain the same ergo not affecting balance. If I exercise every for a year before my surgery and 2 years after, my muscles will elongate to adapt with my lengthened bones. In the process of stretching, if I don't do more that 0.65mm I won't be stretching faster than my body can cope. It seem with my plan I could potentially make a full recovery. Thoughts?
