I scored in 220s for Step 1 and also had a significant increase in Step 2 - 254. I was also not senior AOA but got top quartile. At the end, I ended up matching but it was definitely a grind. The Step 1 will hurt you in that you will get screened out at many of the top tier schools. The Step 2 improvement will definitely be asked about in many of your interviews. I applied very broadly, ~70 in any city that I recognized the name of: NYC, ATL, Cincinnati. Did 3 away rotations + home rotation. I ended up receiving 15 offers (2/3 community programs) and interviewed at 12 and ended up matching. I would have only had about 10 offers but used my connections with attendings, had phone calls made, to increase that to 15. It's definitely possible to match with a Step 1 in the 220s, and I think your extra year in research will definitely help. I'm just going to encourage you to maximize all your connections that you've made in ortho and that you will make in your sub-is.
