I interviewed there. Seemed solid. Residents/Faculty I got to meet were fantastic, super laid back (spent an entire 45 minute interview talking about college football). Residents seemed well prepared for PP or fellowship. Knoxville is great if your an outdoors type person.
I really enjoyed my interview dinner/day. Really liked the program. Only reason I ranked it somewhat low is the resident class size. I was more interested in a larger class size (my program for example has 26 residents/class). The only other ding it got from me was a required away rotation in Nashville which is a good 2.5 - 3 hours away. They do have an apartment they pay for so there is no increased cost per say, and if I were single it likely would not have been an issue but I'm married and I didn't want to spend that much time 3 hours away from my wife.
One of my classmates matched there, I don't think they post on here, but if you want more information I can't imagine they would have a problem getting an e-mail to answer specific questions.
