As one facing shoulder replacement I can tell you that knee replacement is not a walk in the park but far easier to do and has a terrific success rate. You'll be off and (not) running in no time. Seriously, my friend who did both at different times (recommended) that the PT was painful but he is a lot older than you and is a big man, mostly a cigar smoker and bourbon drinker. I think he backed way down though but it might have been too late.
