Let's say there is a 1% serious complication rate of leg lengthening.
Now 1% is hard to make meaning of. "1 in 100" is quite arbitrary to imagine. Is it not much risky at all? Or is it still quite risky? If you could roll a 100 faced dice with the rules that if it lands ONE unlucky face you develop a limp for life, and for all other 99 faces you end up 3 inches taller without complications! Should you roll that dice?
What would make it easier is if we can compare the risk to something normal people undertake in real life.
For example, if there is an 0.1% risk of getting into a serious car accident for someone who drives daily to work, then we can think "ok leg lengthening is 10 times as risky as driving to work daily".
If there is a 0.5% risk of serious injury during skiing then we might hink, "ok leg lengthening is twice as risky as skiing".
I just made up these numbers for skiing and driving. But can YOU think of real life examples with statistics of risk to compare against leg lengthening risks? It can be something many humans go through regularly (pregnancy, driving, flying, sky diving, knee replacements, boxing, playing football professionally, anything like that)
Please explain how you arrive at your risk figures for such activities with relevant links.
