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.”
