How do I list my surgery type in my profile?

I notice that most people include the type of surgery they had on their profile but I can't figure out how to do it. When I go in to update my profile, it only gives me a pull-down menu that says pre-op, post-op, etc. I tried to go in and type after the post-op but it wouldn't let me do that.
