As a adult im 5'9 if I correct bow legs with surgery is there away they could shorten the bone as well?

Bow legs. MRobles ~ the surgery for bow legs can shorten the bones, depending what was done. At 5'9 why would you want to shorten the bones any more? Any questions here should be addressed to an Orthopod who is skilled in KNEE surgery. I am going to wager he will try to talk you out of that enterprise UNLESS there is extremely good reason for it that is not obvious to me here! thanks.
Likely 1 cm lengthen. Standard tibial opening wedge osteotomies will straighten your legs but may actually add 0.5 - 1.0 cm of length.
