Dr. Peter Addison Knoll, MD

Is a pleasure to come into Dr.Knoll’s office his nurses and the people there were always so nice and kind. I always enjoy my time and my visit.

Dr. Knoll was very professional and caring. The surgery was one of the easiest I have had. I was back to normal everyday living in just a couple of weeks. Have already recommended Dr. Knoll to others.

Dr knoll was very helpful and listened to everything I had to say. I would highly recommend him. His staff was AWESOME as well.

Dr Knoll and the staff from sign in up are always helpful, friendly and kind. Dr Knoll takes time to listen to my needs and come up with solutions as I work towards my optimal health for possible replacement surgery. He shares time and knowledge to listen and suggest positive ideas to reach these goals. I know I am is good hands and feel confident in his skills.

Doctor Knoll is a very knowledgeable and intelligent surgeon. He is extremely thorough and I can’t say enough about his compassion and caring for his patients. An orthopedic surgeon in Illinois left me in a precarious situation in April 2025 when a hip that he had replaced for me in November 2021 failed. It completely fell apart and became infected. The surgeon removed it and left me lying in a hospital bed for over four months wherein I became weaker and weaker. The surgeon kept telling me he was going to put in a replacement Hip but failed to do so. After months of laying there, my husband and I contacted Doctor Knoll who had put a replacement Hip in for me in my left leg in 2019. The only reason I didn’t have Doctor Knoll put the replacement hip in my right hip in 2021 was because I live in Illinois and Dr. Knoll’s office is over two hours away from me. Doctor Knoll is extremely thorough and checked everything out completely before proceeding in building me a completely new… hip. Finally on October 2, 2025 Doctor Knoll rebuilt a hip and successfully put it in. Due to the doctor in Illinois letting me lay in bed for over four months and then sending me to a rehab for therapy for an additional two months, my right leg became much shorter than my left leg. Doctor Knoll did the best job he could in trying to get my legs to the same length. I am so thankful for him and his expertise. I can’t say enough good about Doctor Knoll. If you are looking for a surgeon who can do it all, you need to look no further than Doctor Knoll. He is excellent and he is the best!

Dr Knoll is informative, compassionate and takes time to listen. Without his skill and knowledge I would barely be walking. Dr Knoll and his staff are caring and knowledgeable. I feel I am cared for and in good hands.

Dr. Knoll is a very compassionate doctor. He has done two knee replacements for me and it feels great to be able to walk.

Thanks to Dr. Peter Knoll for his medical care and fine professional orthopedic skill and competence. He performed surgery for a hip replacement that I needed on a short term basis and did excellent work. All is healing very well, now two months out, especially w/ quality PT. Justin, my PT at Tri State Ortho, has also helped me terrifically and patiently during recovery. Kudos and gratitude to their helping me recover so well. I recommend them!

I think he was very caring and was good at explaining everything to me. I believe he was very patient with me

Dr. Knoll is phenomenal! He took his time with me and I didn’t feel he was rushing in and out to get to the next patient. He explained what was going on, we discussed options, and collaboratively agreed on a plan. I will return in the future if a need arises. His PA is just as great!
