Dr. Jim Nieman performed surgery on my double tibea plateau fracture 7 years ago. I moved to North Carolina a year later and just had it checked out by the best orthopedic surgeon here and he said my knee surgery was done by an artist and one of the best he has ever seen. This is coming from a doctor who worked at a hospital in New York where all the orthopedic surgeries are tested and they do 10,000 surgeries a year. I highly recommend Dr. Nieman.
