Hey brother,
This is coming from a current MS4 who's going through this process now and who's numbers aren't great...but not horrible either.
1) This process sucks and if it weren't for a lifetime of being rejected by girls, I wouldn't be able to handle all these program rejections right now. Be prepared for that. Sure they like you....but there are 800 other boys hitting on them, and they just don't...like you like you.
2) Agree with everything everyone said. Its all gold. They are all wise words.
3) Definitely consider a research year. Remember that the data from charting outcomes has to be interpreted carefully. Sure yes the more interviews the better, however there are IMGs that do a research year, get only 1 interview (where they did the research year) and still match. Its all about how much a program knows you and likes you. On the other hand there are also IMGs that have done 4 research years and still no one will take them. If a program really knows you and likes you and sees the fire for Ortho in your eyes, loin and groin, there is a good chance they will rank you to match, and as long as one place ranks you up there, you're in.
4) Unfortunately the screening process is dynamic. Program directors can set on ERAS what minimum whatever (step 1, step 2, etc etc) to set to view X amount of applications. As Step 1 averages go up, so does the avg for Ortho and so does the minimum cutoff. It sucks but they have to filter somehow. And this is coming from a PD I know. So yeah, the longer you wait (provided avgs don't drop) the higher the cutoff may become. 230 will get you cut from A LOT of places. I am getting cut a lot, however my score isn't much higher and I'm already getting interviews....so there is hope.
5) Hope that helps. Its awesome that you took the time to post your question on here, and as said many times before if Ortho is your dream, follow it. People with much worse numbers (low 200s, no AOA, avg grades) match into decent programs. Just be a good guy, friendly, hard working, interested. Keep Netters in your pocket, Orthobullets on your phone, read for cases, take interest in topics and people will see your motivation.
Good luck!
