This is a fairly common procedure for children with different length legs to fix a limping gait. My sister had it done back in 5th grade. She has additional health issues, but once the lengthening process was over, I don't recall her complaining about pain from it.

Interestingly, it’s a much less risky procedure on Children, because all the soft tissue around the bones will adjust much more easily than in adults (who routinely lose movement range with this procedure). However, it’s rarely done on non-adults except for medical reasons.
