Sorry to hear that clerkships aren't going the way you hoped. I hate how clerkships are graded and think it is a major failure in our medical education system (eg., picking easy rotations so one can study more, gaming the system to get put with "easy graders", etc), but I digress.
You need to take a long hard look at yourself and decide how much you want to do ortho. If you decide to apply ortho, you need to be okay with the realistic possibility of going unmatched. I say this to anyone applying ortho - the match rate for USMD this year was 74.8%. This ~25% includes applicants who are absolute rockstars, people who have taken research years, etc. My class was 8/11 matched this year and one of our unmatched was coming off a productive research year. They scrambled into a prelim surgery position - not sure if they plan to reapply, go gen surg or do radiology/anesthesia.
I can't tell you how important clinical grades are in comparison to other aspects of your application, but it is not the end all be all. As others have mentioned, there is huge variability school to school. PDs want strong students who are well rounded. This comes in many different forms. For what it's worth, I had 1H and 3HP (+ 3 P/F because of Covid). I was never asked about clinical grades in any of my interviews.
I know there are a lot of people mentioning dual applying. Personally, I am against this. You need to be 110% committed to ortho to match. Any energy you put towards applying to another specialty, getting LORs, etc will take away from matching ortho.
If you decide to apply ortho, bust your a** at your research year. Think of it as a year long interview. Show up early, go to lectures, find mentors who believe in you and will support your application. People have matched every year with deficiencies in their app (low board scores, poor clinical grades, etc). You will need to go all out - apply to 120+ programs, do as many rotations as humanely possible (talk with your school about how to make this happen - you may have more availability with the research year) and let the cards fall where they do. I know it is hard having some perspective of the decision you have to make, but remember that no matter what you decide you will be okay in the end and have a successful career. Good luck!
