Testimonials

I had constant pain in my hip and had stopped doing a lot of my daily activities. After two years, my son convinced me to see Dr. Diana. It was the best thing I ever did. He explained how the anterior hip replacement would spare my muscles and lead to a faster recovery. The day after surgery I walked across the room, and within weeks I was walking “normally” again. I’m back to enjoying life and my wonderful great-grandchildren – and I’m a much sought-after dance partner at our weekly dances!”

Anterior Hip Replacement


In 1990, Dr. Shifflett did a carpal tunnel release on me. In 2001, I broke my shoulder and he successfully treated me, so when my knee flared up he was my first choice. We started with physical therapy and then supplemented with injections and anti-inflammatory medications – this all worked well for a period of time. Eventually the pain became unbearable and Dr. Shifflett recommended knee replacement.
When asked about knee surgery I say – “Yes, it hurts but it is well worth it because I’m able to live my life again!” Dr. Shifflett and the nurses and physical therapists at the Queen did a great job of preparing me, so I knew what they expected of me. I was back to my regular activities within a month, with no pain.”
