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

  • My surgery was a huge success. Had a double fusion on my neck that had been bothering me for a couple of years. Dr. Madigan was able to not just relieve the pain, but completely eliminate it. I finally feel myself again and would highly recommend his services. He also follows up and makes sure you are well taken care of. His staff is amazing and the group at KOC was nothing but incredible. Hopefully I don't need this surgery in the future, but if so...I would do it again.

  • Thanks to my care at KOC, I am now back in my whitewater kayak 7 months after my surgery. Due to severe lumbar stenosis I was barely able to walk 9 months ago. I'm now virtually pain free and back to all activities including whitewater kayaking, daily 2 hour sessions in the gym, mountain biking and hiking. Dr. Madigan is an amazing surgeon and we are extremely fortunate to have KOC in the Knoxville area. By the way, I'm 71 years young!!!!!!!

  • I would like to thank ALL the people involved in both my surgery and recovery both at KOC and Parkwest. I am especially appreciative of Dr. Madigan for his experience and knowledge of his accurate diagnosis and skill. The pain that I was experiencing in my arm, neck and head as a result of my vertebra at level C2 C3 pressing on my spinal cord have all since disappeared with exception of the surgery which is getting better each day. I am amazed and so grateful for the medical technology we have in today's world and and the incredible dedication to learn. Thank you Dr. Madigan!!

  • Thanks to my care at KOC, I can now resume my normal daily life activities and begin training to get back to my prior active lifestyle. October of 2018 I was suddenly presented with searing nerve pain in my left hip and weakness in my left ankle. I was able to make an appointment with Dr. Madigan within 3 weeks and he quickly took action. An MRI confirmed his early assessment that my L4/5 disc was herniated. He started with a less invasive approach of a steroid spinal epidural. It had little effect so the options were to either try another epidural or fix the problem. Dr. Madigan was certain that the surgery (remove the rock off the hose) would fix my problem. December of 2018 (12 weeks after initial issue) I had surgery. In recovery I already felt better and immediately could stand without pain. Two days later I was walking around Turkey Creek with my family. I followed the therapy protocol and had minimal discomfort in recovery. I was back to work two weeks after surgery and now 10 weeks after surgery I am working with a PT to train more aggressively to get back to cycling and running. Throughout the process, Dr. Madigan and the KOC team were professional, friendly, thorough, and willing to answer all of my many questions. Dr. Madigan and KOC team, you are my heroes!

  • Thanks to my lower back surgery with Dr. Madigan, I can do anything I want. Absolutely thrilled with the results from my surgery!
    – Brian, Maryville
  • While just 5 days out of surgery, I am very pleased with the progress. I am well ahead of what I expected as far as pain and mobility. Dr. Madigan did a fantastic job of outlining the source of my problems and laid out the different options available to me. Together we chose a path of care and identified the struggles and the issues. While it has only been one week, I am well ahead of what I had expected. While spinal fusion is a serious path to take, Dr. Madigan helped me understand the risk and the rewards and was able to easily explain the process. I have enjoyed the care provided by him and his assistance through this process.

  • I saw Dr. Madigan. My wife and I both felt very sucure with him instantly. Ver good bed side manners, talks very clear. And that's great when you're hard of hearing. He was a very quick to inform us both of what he was going to do as a surgen. Showed us the problem and what he could do do help me with my back pain. And I have to say he was absolutely one of the best. He and his assistant Raven are on top of things. Would recommed him as a doctor with great bedside manners. He does what he says and in a very timely manner. Keeps you in the loop all the time. Thank you Dr. Madigan for such great care. We would very highly recomment KOC family of doctors. They do know what they're doing.
