Not pausing in the middle is certainly more challenging. It exerts greater strain on the body, with the limbs being subjected to nearly 2mm of lengthening each day. There is extensive interconnection between the tibia and femur structures, making it more difficult to achieve maximum height. Physiotherapy also becomes more demanding. I delayed my surgeries by 1.5 months, and I believe undergoing them concurrently is not logical or sensible. It is important to allow your body sufficient time to recuperate between surgeries. I elongated my tibia by 5.8cm initially and have now reached 4cm on the femur, experiencing various complications along the way. Both procedures were highly precise.
