Not sure about the above, but my Golden (non hunting) had TPLO done August 2011 at www.vosm.com and I would highly recommend that office. This place is amazing, and perform stem cell therapy, spinal surgery, and much more than that. It's located in Annapolis Junction, Md. I recall several owners from out of state during my brief time there. They would stay a night in a hotel, and pick their dogs up the next day. Guess they made the few trips back for check ups, and did the rehab themselves as I did.
I think once it was all done, total cost was around $ 3,500.
