Even if he would have survived the process i doubt the he would ever fully be 100% i had a patient i was doing bilateral knee xrays frequently in the clinic and he got this same surgery done where they essentially break your legs add rods to increase your height. Dude was 2 years off the surgery stll in alot of pain had range of motion issues and He admitted he was concious of his height.Breh was 5'8 and gained enough inches to be 6'2 but regets it because the knee pain,hospital bills,etc wasnt worth it.
