Pretty standard stuff really... nothing you wouldn't expect:
Why do you want to do ortho?
Explain (negative aspect of your application).
Tell me about your research.
Tell me about yourself.
What was it like doing (some activity you listed on your application)
Why will you be a good fit for this program?
Why will you be a good orthopaedist?
Blah blah you get it. Basic interview stuff.
