Dr. Mark Powell is an excellent Doctor. I am 78 years old, and my right knee was very painful when walking. He explained everything and gave me pictures showing the source of the problems in my knee, and what he would be doing in surgery to solve the the situation. He gave me details and was very reassuring about what caused the difficulty I was having and what procedures to do, including Physical Therapy, following the surgery. He emphasized that he wanted me to WALK and NOT sit around. ( He was even emphatic to my wife, that she was NOT to wait on me !!!--she has followed his instructions!!) His confidence In my ability to be able to walk without pain, following surgery was VERY reassuring. Also, his nurse, Mary Martha, was excellent in making sure to go back over the Doctor's instructions, making sure I understood clearly what I was to do. I returned as instructed, for Dr. Powell to be checked. I highly recommend Dr. Powell and his staff for ANY orthopedic procedure.
