From the moment I checked in at the front counter I knew my visit was going to be great. The x-ray technicians were nice. Dr. Duffy’s assistant was nice and of course Dr. Duffy was nice. It’s been years since I have seen him. But he acted like it was just yesterday. He listened to my concerns and did not rush my visit with him. I was very happy when I left his office.

My condition didn't fall under Dr. Duffy's field of practice. Nevertheless, he and his lovely assistant, Lacey, showed me patience and compassion. He referred me to another specialist and I have confidence in his recommendation. Dr. Duffy earned 5 stars and I will see him again when my condition warrants it. Thank you!rater8 Verified Patient

Dr Duffy is an awesome doctor. He has helped me tremendously with my knee pain and recommended PRP treatment which I received. My knee pain is gone and I am very grateful for the immediate results. Most recently he diagnosed pain in my hip with the same expertise. He has a very straightforward approach to let you know what is going on with your situation and I highly recommended Dr Duffy for your knee or hip pain. He’s one of the best doctors I’ve had the privilege to see.Patient Submitted Review

Went to get second opinion on knee replacement surgery. He provided an outstanding assessment of my X-Ray and the status of my right knee. He has a great bed side manner and provided his honest opinion that I do not need replacement surgery and he would not do it…he said I need to cut back on impact related exercises and do more bike, etc. Love the guy. Would highly recommend to any considering knee related issues.

Very pleasant, intelligent, and right to the point! I came in, fully expecting to be told I needed to have a total knee replacement. But options were explained, and I had a cortisone injection right then. It was not at all painful!!!! I was then fitted for a brace. Upon returning home, a few hrs later , I noticed immediate relief. Having pain for the past year, which the past couple months, was vey excruciating and debilitating!! In the few days, since the injection, I feel much better!

Dr Duffy took the time to thoughtfully answer my questions with clarity - which was most important to me. I’ve been distrusted by not getting answers from others. He was courteous and respectful and caring. I really liked him and felt seen and heard. He helped me establish a treatment plan and lifestyle modifications to move forward. It was a great visit.Patient Submitted Review

Had a great experience, came in with a lot of knee and leg pain… had been seeing a pain specialist who gave me zero relief from my knee pain. Was given an evaluation and a cortisone shot (that did not hurt) and I am able to sleep through the night without waking up at all hours. I am happy with my experience so far and look forward to seeing what Dr Duffy can provide for a longtime solution. Highly impressed and will freely recommend Dr Duffy to anyone suffering from knee issues and knee pain.Patient Submitted Review

From the front desk to the xray techs to the nurses to PA Earl Miller to the clerical staff to the surgery schedulers to Dr Duffy …Greatest experience. It reminds me of a finely tuned machine. On top of their game. Anticipate your needs. I realize it’s a huge practice and thus much harder to keep things fine-tuned. So my appreciation is that much greater. Just had my hip replaced 8 weeks ago and Dr D is just stellar. Thank you all if you’re reading this!!! #duffysteam

After posting a search on a local Community App for the best knee specialist, I received over 60 responses. Of the top 5, Dr. Duffy came out on top. I just came back from a consultation with him.

I’ve had 15 surgeries in my life. I’m 67 years old seeing plenty of orthopedic surgeons. No one comes close to Dr. Duffy. He explains what’s going on with your body and he looks you right in the eye. Every time he speaks you can tell Dr. Duffy loves what he’s doing and cares for his patience, I would not hesitate one second to recommend Dr. Duffy or the entire office to any of my friends or relatives.

I was very nervous due to my pain and confused when I saw Dr Duffy. He was reassuring & was patient with me. He explained the MRI, Xrays and treatment plan in detail.

It’s been 9 years now since both knees had to replaced. I had to get a check recently for an FAA medical as I’m a pilot. The work he did is still in excellent shape and closing me up, you need a magnifying glass to see my scar. We all heal differently I know. Point is his work in my case was exemplary. Im 61 going on 21 extremely active, and the human parts around the knee act up if I over do it. Weird mostly cramps and such but that’s my body not his work. I’ll never forget our first meeting, I made the mistake of asking about different prosthetics,’and somewhat arrogant, he told me patients don’t get to choose what he uses…they would be the best but the question I should be asking is his experience. I hired him on the spot. I’m the same way as a pilot…exceptional! The work he did on me I would recommend a million times over. The other side of the coin is, like I alluded earlier, his work gave me the ability to act 21, my human parts don’t always conform. Simply the best.Patient Submitted Review

Dr Duffy changed my quality of life!!! I chose him because he was the only Dr who provided infection % rate out of six other dr opinions. I lost a brother to an infection because of surgery and know of others who have lost limbs because of infection from surgery so this was the difference.

Dr. Duffy has performed joint replacement surgery on both of my knees, one in December 2014 and the other in February 2015. After surgery and completion of therapy my knees the pain I dealt with for years was gone. I have not had any issues with them since. I see Dr Duffy annually for a check up. Everything is great. Dr. Duffy is a great surgeon and in my opinion an even better person. It’s easy to tell that he genuinely cares for his patients. I strongly recommend him for your knees or hip problems.

Dr. Duffy addressed all my questions and concerns before I could even ask. He was even aware that my insurance would cover a procedure. I have not had an appointment for over a year, so X-rays had to be done. He did not make me feel bad about not keeping up with my cortisone injections, but did make me feel good about losing 17 pounds since my last visit, and made sure I knew what a plant based diet was by asking me questions in what I eat. He did not tell me I should not be on a plant based diet. I really appreciated that. He is very personable, friendly, very neat in appearance, and knowledgeable.

Dr. Duffy performed my total right knee replacement after trying several nonsurgical remedies. He is very patient and explains everything in detail using easy to understand language. My knee replacement surgery was a work of art by a skilled craftsman. I had a minimum of pain post op, zero complications and recovery was much, much easier than the horror stories I heard from other knee replacement patients. His entire team both in the office and in the hospital are world class. Professional, caring, skilled empathetic and encouraging throughout the experience. I had my 3 month post operative follow up today. My scar is practically invisible, I am able to perform all tasks I have attempted, my range of motion is better than before surgery and my recovery is months ahead of schedule.

I feel like my body is an old broken down jalopy that has to get joint replacement and back and cervical surgeries one after another from accidents and age. I had a rt knee replacement in 2000 that was a nightmare experience with a terribly long recovery. I finally had my left knee done by Dr Duffy and I can't say enough good about the skill level of this doctor and the organization of his team. no one is perfect but this is as near perfect a situation as I have ever experienced. At 69 years old this knee replacement has been smooth and successful and an accelerated healing even after the first two weeks of pain and discomfort. My leg is straight at 3 months out I have next to no pain at all and the scar is disappearing to a hairline. Next will be the left hip. Thank you Dr Duffy for doing that x-ray to see that my hip was all bone on bone rather than me continuing with treatment for pain rather than roof cause from another physicianPatient Submitted Review

Dr. Duffy is the best orthopedic doctor. When he saw me I had been in pain for over a year as many doctors thought it was my back. He knew it was my hip and wanted to try cortisone shot and therapy, but nether helped. He scheduled my surgery and his staff was very thorough with me. My husband was involved with the class we took and all the testing I needed prior to my surgery. The day of surgery Dr. Duffy promised me no more pain. He was so right. Even after surgery that pain wasn't anything like the pain before. I was only on pain meds for 3 days. I worked hard to retrain my muscles and was so proud of myself. I was back at work in 5 weeks. Everyone is truly amazed at watching me power walk on my 10 minute break at work. I got my life back and I can't be happier. Thanks to Dr. Duffy!!!!Patient Submitted Review

That made me feel like he cared. I have been singing his praises ever since. I have told many people to go to him.Patient Submitted Review

I had many long, frustrating years with my knee until I saw Dr. Duffy. After he reviewed my situation, we discussed and tried options before deciding surgery was needed. I am now 3 months post-op from a total knee replacement, and I feel almost no pain. I am absolutely delighted that I have resumed my active lifestyle. He's the best!Patient Submitted Review

Dr. Duffy performed hip replacement surgery for me 4 months ago. The experience was life-changing. From the moment I woke up from the surgery, I had no pain. After living with constant pain for months, the transformation was amazing. My recovery was so much easier than I had expected. Dr. Duffy was heavily involved all the way through the process, from helping me decide to move forward with surgery, all the way through my post op appointments. I would not hesitate to recommend him to anyone.Patient Submitted Review

Dr. Duffy is a highly experienced, extremely skilled orthopedic surgeon. My experience with him was very successful due to his positive, open communication skills as well as his skill as a surgeon. He expresses himself as a person who loves his work and takes personal and professional satisfaction when his patients have the outcome they desire. I can truthfully saw my total hip replacement was pain free and complication free. My new hip functions as if it were my original.Patient Submitted Review

There are so many people to connect with during a surgery/recovery. I was always glad to see Dr. Duffy. His ease and "personability" was a huge plus. based on my healing both in ease of movement and physical appearance of the sugery site, this is a good surgeon, and a good surgery team. Appreciate the sense that he knows me despite the number of surgeries he's doing each week.Patient Submitted Review

I had been in severe pain for almost 3 years due to a Major Clinic in jacksonville telling me that my leg pain was all due to my back problems. Dr Duffy was thorough and sent me to a neurosurgeon for a consult before doing total right hip surgery to make sure . I can now walk ,standing up straight,without leg pain. He is the best and renewed my faith that there are still some Doctors who care-he answers all your questions and I wouldnt go to anyone else-he gave me back my lifePatient Submitted Review

Any patient who is headed for knee or hip surgery is in for a treat if Dr. Duffy and his staff are involved. He is friendly, engaging, humorous, and just a lovely, handsome man. He and his group know their business and set out to do the best job possible. They address any concerns a patient may have and stay in contact long after the surgery. I always look forward to my yearly check-up since my knee replacement surgery 5 years ago. Dr. Duffy is quite a treasure in Jacksonville.Patient Submitted Review

Everything about my experience was great! Once I realized the severity of my need for surgery, I was able to pre-hab which was a great help going into physical therapy after surgery. I had a 20 degree bend in my knee as well as needing total replacement. Now 18 months out from surgery,my leg is straight and I have my life back. Thank you so much!!Patient Submitted Review

Dr Duffy has been my dr for 5 years and I wouldn't go to anyone but him. His surgical skills are excellent. His bedside manner is awesome and he always takes the time to thoroughly explained every procedure. His PA's are equally as professional! He really DOES care about his patients. So if he is running behind on an appointment he is worth the wait. GO TEAM DUFFY!Patient Submitted Review

I can't say enough about Dr. Duffy. Two people I know referred him to me and if I ever need another procedure I would not hesitate to have him as my surgeon again. I had a total hip replacement and had no pain from day one after surgery. I rate Dr.Duffy 5 star. He took his time with me and absolutely cared for my well being.Patient Submitted Review

Dr. Duffy and his team (office, hospital, physical therapy) are a well oiled machine. Everyone I come in contact with are kind and caring and make me feel like I'm their only patient. Through the surgery and post-op, I never felt neglected--was visited by Dr. Duffy and his team on a daily basis. During office visits I never feel rushed and never leave without all my questions being thoroughly addressed. I highly recommend Dr. Duffy to everyone needing a hip replacementPatient Submitted Review

Dr. Duffy really cares about me and the quality of care that I receive. I'm mid-40s and he performed a total hip replacement on me 3 months ago and I feel like I've gone back in time about 20 years. He's my angel. He's funny, he's cool, he's genuine, he makes me feel like I'm his only patient and he's incredibly skilled at his job. I trust this man and would have him perform any additional procedures. Even if I were to relocate out of Jacksonville, I would come back for him. LOVE this man.Patient Submitted Review

Dr Duffy have been my doctor for over seven years. I had the privileged of have \r Dr Duffy perform both my hips and a knee replacement. I never had a Doctor in\r who care so much that he visit me each day I was in the hospital.I considered \r him to be my number one doctor and refer him to all my friends in my community\r and church. Thanks Dr Duffy for all you do“I found the most compelling reason to use Dr. Duffy was that his entire team shows genuine care for patients. Yes, he is an excellent orthopedic surgeon, but more than that, he and his team have genuine empathy for the whole patient process; from calling the night before surgery, to ensuring a strict and very proactive follow up through the nursing care and the physical therapy process. I cannot recommend Dr. Duffy and his team highly enough. Both of my hips are perfect and I feel great!” William F.

From the moment I checked in, the staff was kind and professional. Dr. Duffy took his time with me and actually sat down to talk to me while explaining images and his thoughts on best next steps. I had a previous experience at another area large Orthopedic practice which was the exact opposite of my experience at Southeast Orthopedics. Thank you Dr. Duffy.
