Many of the Dr. Best patients have lengthened over 8cm in their femur without Itband release surgery. Although they got wide legs but it become better after their finishing lengthening.

On the other hand, Dr. Paley's femur patients always receive Itband surgery no matter how many cm they want to lengthen.
Besides, I find many runner have some problem with Itband but still do not want to receive Itband release surgery.

Why do you think the difference?

Do you think Itband release surgery is necessary in femur lengthening?
