Just a follow-up...
So I used the PlasticsMatch personal statement editing service (google it) and it was an enormous help. These guys are professional, quick, seem to have a great understanding of the ins and outs of orthopedics and residency, and were a lot cheaper than a few other services I looked at. Anyway, something to think about if you're struggling or just need someone to proofread and give you feedback.
