There's absolutely nothing wrong with matching at your home program, especially if its of good quality (I matched @ home btw).
You get more face time with home ortho attendings and residents since:
1) you run into them in the OR/ER as you plough through your other rotations.
2) You do research with them.
3) You skip lame medicine/obs/geriatrics rounds and go to ortho rounds!
When I walked into my home program interview, I felt relaxed because I knew everyone in the room, they knew me, and I knew what the program was all about and what resident life was like. This is a tremendous advantage to have since you know they are going to ask you: 'why ortho?', 'why here?', 'tell me about your research', etc.
Get to know your home attendings and let them know about your ambitions...they are usually in the same hospital you are in!
