Luke Madigan, M.D.

Spine Specialist


As the son of an orthopaedic surgeon, Dr. Luke Madigan felt a strong calling toward medicine from an early age. After graduating with a B.S. in biology from Trinity College in Hartford, Connecticut, he earned his medical degree from Thomas Jefferson University in Philadelphia, Pennsylvania. Dr. Madigan remained in Philadelphia for his internship and residency in orthopaedic surgery. He then completed a fellowship in spine surgery at OrthoCarolina Spine Center in Charlotte, North Carolina.

Fascinated by the complexities of the spinal cord and inspired by the motivation and enthusiasm of his chief mentor at a busy spinal cord injury center, Dr. Madigan is pleased to serve at KOC as a spine specialist. He particularly enjoys seeing his patients return to their favorite activities and enjoy life again. His special interests within his field include cervical myelopathy, spinal cord injury and degenerative conditions of the cervical and lumbar spines.

Dr. Madigan is married and has one son. In his leisure time he enjoys running, working out, home improvement projects and spending time with his family.

What patients say about Dr. madigan

  • Thanks to my care at KOC, I can go back to living the life I was used to with no pain. Thank you to Dr Madigan and his staff. He was there when I needed him.
    – Mike, Friendsville
  • Thanks to my care at KOC, I can walk again with no pain and I can finally sleep on my side. Dr. Madigan is a no beat around the bush doctor. I had back surgery recently after a lengthy journey trying to avoid it. Best decision I ever made. He explained everything to me in layman's terms and all the guidance throughout. Recovery was great and Dr. Madigan puts it out there with regard to progress - It's like - hey you've got to take care of yourself if you want to continue your healing journey. I like him - very personable, warm and friendly - and I'm healed!!! Thanks Dr. Madigan - you are an excellent surgeon and have a superb bed-side manner.

  • Thanks to my care at KOC, I can start to be on the road to recovery from constant neck pain. I had my neck fusion done at the Outpatient Surgery Center next to the West Office. Dr. Madigan was very informative and his knowledge of my procedure gave me confidence that I was at the right place. I’m glad he did my surgery and I would use him again. He is an excellent surgeon.
    – Bobby, Morristown
  • Thanks to my care at KOC, I can walk without pain in my left leg! I had a herniated disc with debris affecting two nerves in my left leg...very painful! After initially seeing Dr. Madigan, I elected to try the less invasive steroid epidural, leaving surgery as the last option. Unfortunately, after experiencing only temporary relief from the second epidural, I had to choose surgery, the last resort, but I had outstanding results! I am back to my life walking my dogs, driving distances, and walking without pain! I am so grateful to Dr. Madigan for giving my life back! I would highly recommend Dr. Madigan, who is conservative, but if surgery is the necessary decision, he got the job done! Thank you, thank you, thank you!
    – Cherie, Knoxville
  • Thanks to my care at KOC, I can walk again! All the praise goes to God and Dr. Luke Madigan. Due to spinal stenosis and rheumatoid arthritis, I had become almost bedridden. Each step caused severe pain. Then Dr. Luke Madigan preformed a lumbar fusion L3 to L5 on my spine on May 16, 2016. I found him to be compassionate and knowledgeable. He took the time to answer all of my questions. He even allowed me to pray with him prior to my surgery. My recovery went as expected. The first two weeks were very painful, then my body began to recover. Now six months out, I have no pain in my lower back. I was concerned about becoming addicted to pain medication, but Dr. Madigan keeps a close eye on that and only prescribes what you need, reducing the dosage as quickly as possible. I was so satisfied with Dr. Madigan that when my husband needed back surgery three weeks ago, there was no question who would be preforming the surgery. My husband is also recovering extremely well. He had a herniated disc. I would highly recommend Dr. Luke Madigan. You will not find anyone better. Thank you for giving me my life back Dr. Madigan!
    – Brenda, Knoxville
  • Thanks to my care at KOC, I can turn my head and neck without severe pain. I have degenerative disc disease that gets increasingly worse every year. Dr. Luke Madigan was very understanding and willing to help me get relief. He was very easy to talk to and explained what he thought would help me. I was very happy to find someone that I feel I can call on and depend on to help me in the future. I would highly recommend Dr. Madigan.
    – Delbert, Knoxville
  • Prior to surgery I was struggling with a loss of flexibility, and limited mobility due to pain. Dr. Luke Madigan performed a lumbar laminectomy for spinal stenosis. At seven weeks post surgery, all of the pre-surgery issues are resolved and I feel better than I have for 20 years. Thanks to the care I received at KOC, I can roll my whitewater kayak again.

    Dr. Madigan is an exceptionally skilled and caring surgeon who has earned my deepest gratitude and respect. My only regret is than I didn't have this surgery 5 or 10 years ago!
    – Thomas, Tellico Plains
  • I had visited three other spine specialists who had not been able to relieve my pain. None had suggested surgery, perhaps because of my age (73), but Dr. Luke Madigan was a very caring doctor who showed no hesitation in explaining the surgery thoroughly, both pros and cons, and recommending that I have it and carried it through with great success. Very, very happy with his work and I would recommend him highly and KOC in general. KOC doctors have performed knee replacement on both my knees, saved the use of my husband's hand when he cut tendons, and helped him through a broken ankle. Where would we be without all of you?
    – Sandra, Knoxville
  • Since my Cervical Spine procedure, I can go through my normal daily routine without pain. I have suffered for many years with migraine headaches, missing out on activities with my family because of the pain. Since my procedure I have not had a migraine (or even a common headache). This is like a miracle for me as medication always left me in a fog. I can walk farther without pain, have more energy, just over all feel better.
    Dr. Luke Madigan sat down with me prior to the scheduling this procedure, explained the surgery, recovery time, common side effects, pain management, and overall what to expect. He did not leave the room until he was sure my questions were answered. He reviewed my films with me pre- and post-op. He made sure I understood the procedure which is a comfort to me. I have been a Nurse for over 25 years and he still took the time to explain, ask my input, giving me a voice in my care. He addresses concerns and questions during follow up.
    – Debora, Andersonville
  • "From the time I started visiting Dr. Luke Madigan, I was given the honest opinion about my situation. Without having this operation on my back, I don't know where I would have been in the next two to three years from now. I can walk normal again without wobbling side to side as if I were a penguin and I am now pain free without leg pain aching me constantly for the first time in about 5 years. I'm so thankful for the help and everything Dr. Madigan has provided me with, I will now be able to enjoy my life."
