Hey Soopz,

You will never be 100% due to the stretching of muscles/tendons and the altered biomechanics of your lower limbs.

Food for thought: There have been cases of fatty embolism from bilateral femurs that have caused death to the patients. I know you are looking to do a few cm on tibias, but you could possibly my friend.

3cm is a high risk low reward kind of goal IMO.
