Your numbers are probably somewhat below those of the average med student applying to Ortho, but numbers aren't everything and yours aren't terrible. You can't change the past, but my recommendation would be to do 3 away rotations if possible and bust your ass to make a good impression. I know my program puts a fairly large emphasis on taking rotators. There are probably a fair number of programs who are willing to look past lackluster numbers and take a guy (or girl) who they know will work hard, gets along with others, and will be a good fit in the program.
