What patients say about Dr. nadaud

  • Thanks to my care at KOC, I can get back to hiking with my family, pain free.
    – Beth, Powell
  • Thanks to my care at KOC, I can walk and perform all the chores and jobs I need to! I had total left hip replacement in 2003 and today I'm having some cosmetic work done again. Then in about 3 months Dr. Nadaud will replace my right hip. Then I will be in good shape to start enjoying my life again.
    – Roger, Seymour
  • Thanks to my care at KOC, I can now do the routine things I used to do without pain: mow my yard, ride a bike, hike, use stairs, and walk with my wife. The knee pain had gotten so bad that the simple act of walking was becoming difficult as time progressed. We enjoyed traveling, but that had not been much of an option for the last couple of years. I'm happy to say that on January 7, 2019 (just over 3 months after my surgery, which was October 5, 2018) we enjoyed a trip to Israel. The attached picture shows us on the Mt. of Olives overlooking Jerusalem! We walked/hiked 53 miles over a seven day period. There is no way I could have done this, or even attempted this trip, prior to Dr. Nadaud performing the partial replacement. Thank you Dr. Nadaud, staff, and the KOC team for restoring the quality of my life!
    – Wade, Middlesboro, KY
  • Thanks to my care at KOC, I can go to Disney World with my family! Eight weeks post full knee replacement I went with my son's family for a four-day trip to Disney. Thanks to Dr. Nadaud and his fantastic staff, I enjoyed my vacation! I received wonderful care at Knoxville Orthopaedic Center!
    – Delaine, Clinton
  • Thanks to my care at KOC, I can now hike in the Smokies and walk without pain!! I now have 500+ miles of hiking under my belt!! In April 2014, Dr. Nadaud performed bilateral total knee replacements on me. Prior to the surgery, I had been in a lot of pain and had a significant limp and altered gait and I had dealt with this for several years. I was reluctant to have such a major surgery but I am so glad that I did! For years before the surgery I could not even walk long enough to shop without so much pain! I dreaded even grocery shopping! Having hiked before my knee problems, I never thought I would be able to hike again. Wrong!! One year after I had the surgery, I was able to hike to Mt LeConte! This past Tuesday we hiked to Mt LeConte again which put my husband and I over the 500 mile mark for hiking in the Smokies since 2016. I attribute my ability to hike to Dr. Nadaud who essentially gave me back my ability to live an active life! I do not have any knee pain now! Of course, I have a little soreness after a long hike but this is normal! The soreness is gone in a day or so even after a long hike! I am so thankful for Dr. Nadaud and his expertise and kindness. I recommend him wholeheartedly! He is the best from my perspective! I am eternally grateful! Thank you Dr. Nadaud!
    – Cathy, Maryville
  • Thanks to our joint replacements at KOC, we just got back from an Alaskan Cruise and we walked 86 miles! Yep, 86! Thank you Dr. Nadaud for "fixing" us!
    – Vickie and Bruce, Crossville
  • Thanks to my care at KOC, I can continue enjoying the activities I love. I put off knee replacements for years, thinking it would not benefit me at my age (73). I can not thank Dr. Nadaud and his staff enough for what they have given back to me. After my visit with Dr. Nadaud and all his encouragement, I had both knees done July 1st 2019. 13 weeks later, I was on a flowrider (surfing), and have plans to be back on the snow (snowboarding) this winter. It was my idea for many years; if I have knee replacements, they will not support any extreme activities. If you are one who has the same fears, talk to Dr Nadaud. All I can say is THANK YOU!!!!!
    – Charlie, Jacksboro
  • After a partial knee replacement in Sept. 2017 I am back on the slopes! Thank you Dr. Nadaud, Dr. Betcher and the KOC joint replacement team!!
    – Robin, Maryville
  • Thanks to my outpatient total knee replacement just 8 weeks ago with Dr. Nadaud at Knoxville Orthopaedic Surgery Center, I'm already able to work on my garden. I'm also excited about fishing and hunting season this year, as I wasn't able to go much last year due to my pain.
    – Marshel, LaFollette
  • Thanks to my hip replacement with Dr. Nadaud, I am back on the tennis court, golf course and trail riding with my wife. Life is great.
