I've been trying to respond to as many of these posts as possible, since I was just recently in your position. However, I don't have much to add to my previous comments. Getting interviews is pretty formulaic.
You need a good Step 1 and clinical grades as your foundation. I would say in today's applicant pool, >230 is absolute minimum, but preferably you want to be >250. HP in surgery and medicine are again your entry point, with honors in both being preferable. You need to demonstrate participation in some sort of research in any field, preferably in ortho, and preferably with some abstracts and papers to show for it. Finally, extracurriculars are not needed, but can help distinguish yourself, such as an additional graduate degree, participation in varsity college athletics, or connections to famous orthopaedic surgeons.
Just like your CV, as a rotator there are fundamental things you can do to rotate well. You absolutely need to know the bread and butter anatomical approaches to the hip, knee, ankle, shoulder, elbow and wrist. You should always show up early, be courteous, and be a team player. Read orthobullets to brush up on rotation and case specific knowledge.
If you do these things, you will do fine. It's not as much of a pandora's box as some people may think.
