As a well below average height guy who had knee surgery following an ACL tear: no freaking way I would even undergo surgery that wasn't absolutely necessary. Your bones may heal, but what about your muscles and the nerves they touch? Being healthy is way more important than looking good. I have (small) problems even from a routine intervention, I don't even want to know what these experiments yield.

And as insensitive as this might sound: get over your god damn insecurities. All the statistics in the world of how much more money tall guys make can't account for individuals, and we all know plenty of short rich business owners and poor big guys working terrible construction jobs or worse. The only real limitation in being short is dating tall women. But guess what, there's plenty things limiting your dating pool: baldness, being fat, facial features, age, social and financial status, etc. Nobody has it all and you will never finish if you go the rabbit whole. You can only end up like those women butchered by too much cosmetic surgery.
