Some of the replies in this thread are the kind of stupid shxt that was parroted in the older years of this community.
No, you need much better reasons to be seeking to do a procedure that requires a career break from most people, loans or years of savings, risks multiple forms of embolism, risks duckass, misalignment, infections, will most likely give you early arthritis, will permanently hamper your athletic ability, and takes years of your life to fully recover and move on from (and will probably require additional surgeries).
177.5cm is objectively tall. The average male height worldwide is 170cm, and even that is probably inflated as it relies on self-reported surveys. I don't care if anyone feels short at 177.5cm because they're from the Netherlands or something. Reality is not up for arguing. Your subjective experience is, but that can be treated without risking this much.
You need a much better reason and to do much better research if you want to undergo CLL at heights like those. "Feeling a bit short" is not one of them.
And with a mother as short as yours were, you, poster from two years ago, should be really glad you didn't end up at less than 175cm. Considering you never came back, I hope you just got over this insecurity of yours and counted your blessings.
