I guess what I mean by 100% athleticism is being able to do the things you were capable of doing before and maybe a bit more. Like I'm squatting a bit over 400 lbs right now. If I work hard can I squat 430 lbs after 2 years post-op surgery?
i guess we have to break it to down to :
loss of muscle volume from distraction
relearning to squat with new biomechanics
most of your docs will probably tell you not to lift heavy until your hardware removal+ 1 month
so lets say thats about 13/14 months
if you were to decondition for 13 months lets say your squat would go down to 135
but it comes back quick, probably in 4 months youd be comforably i the high 200's again
but with the new height
youd have to change the way you squat
are you high bar masterrace? or lowbar?
i post this vid on here all the time
im assuming youre gunning for femurs?
tldr: post op regaining your muscle mass will come relatively easier. however you will need to retrain your body to adapt to new proportions/centre of gravity. i think reaching 430 in 2 years is too lofty of a goal ( unless you use gear then thats probably reasonable) but i would give yourself a full year from fully healed ( one month after removal) to get close to baseline
