So I am not sure where you are getting this idea but a basic orgo class is not really going to help with gene editing. Biochem might. Advanced genetics and biotech classes might. But not orgo directly. Also, I am pretty sure some work recently came out that a lot of people have immune responses to CRISPR so that throws a monkey wrench in that plan. Oh, and, germline gene editing is overwhelmed with ethical complications.
But anyway, ignoring all of those things, if you are going to be a practicing ortho surgeon then you will not be having the time to work on gene editing. You might be able to be a partner in a company that works on that type of thing but I think you would just be a financial source and not have any contact with the development of the technology in that case. You might be able to work on that type of stuff if you pursue a different specialty and try to work in a highly academic setting (big research school with fancy hospital). Maybe MD/PhD would help with that too.
I know a lot of what I said may have come off as rough or mean. I just think you haven't had the exposure to some of the experiences in medicine and upper level sciences that would allow you to come to these realizations yet and that isn't your fault. You should take the class if you think you are ready to put in the work to do well in it. It is a bit of a foreign concept compared to basic bio or inorganic chem classes (which was most of AP Chem if I remember correctly). Aim high and pursue one of those two dreams you posted about.
