So you're saying there's a chance!
Seriously, the "big scare" should have come when you got your score back a year ago, not now as you are applying for aways. Based on hundreds of previous posts, it is no secret what a reasonable score would be to expect to match into ortho. Kicking it in gear and blowing away your clinical grades would have been a good strategy. There are MANY programs that cut-off their rotator list, and many more that will allow you to rotate, maybe even interview, but never really consider you a realistic applicant because of your step one score. I would bet that more programs than not cut off their interview list at or above 220. I'm not saying it right, but it is reality.
There are certainly stories of people with lower step one (even failing step one) matching, but for every one that has, there have been thousands that haven't. Usually the person with the low step one who is successful at matching does so because they are exceptional at something else, not just an otherwise "solid" candidate. 95% of those applying are "solid" and have better step one scores. Your best bet is to realize just how far behind the eight ball you are, and take aggressive steps to counter that fact. You need to do as many away rotations as possible at programs that are not as academically focused and literally smoke them all without rubbing anyone the wrong way. In my opinion, you would probably be better served rotating at a few community programs with fewer residents and staff so that you have a better chance of some face time with the chair or residency director. Many larger programs have several students rotating at the same time and can easily get lost in the crowd. Sorry for being so blunt, but I'm trying to be helpful.
