Patient Rating
Patients consistently describe Dr. Ernat as knowledgeable, thorough, and skilled, often noting that he identifies findings on MRI that others missed and explains diagnoses and treatment options clearly. Many reviews emphasize that he listens carefully, takes time to answer questions, includes patients in decision-making, and coordinates care with colleagues and staff. While feedback is overwhelmingly positive, a small number of comments report isolated experiences of feeling rushed or dismissed.
Generated via Patient Reviews
The patient rating score is an average of all responses on our patient experience survey. The rating averages scores for all questions about care from our providers. The scale on which responses are measured is 1 to 5 with 5 being the best score.
Patient comments are gathered from our patient experience survey and displayed in their entirety. For the convenience of our visitors, some patient comments have been translated from their original language into English while preserving their original meaning as accurately as possible. Patients are de-identified for confidentiality and patient privacy.

I had a very good experience wth Dr. Ernst. He was rofessional, but personable. He listen t my oncerns and responded to them completely.
Dr Ernat caught something on my MRI that the radiologist missed. His exam supported his findings. Without that finding, the proper surgery would not have been ordered. I hate to imagine what would have come of my knee if a surgery was performed without all the pertinent information. Thanks Dr Ernat, for saving my knee!
Dr. Ernat is a great provider! Kind and competent. I'm happy he is my surgeon!
He really cares about the well-being of his patients
Dr Ernat was straightforward in explaining the best pathway forward to fix my torn meniscus. He took the time to address all of my questions and was able to get me on the surgery schedule in a timely manner.
Dr Ernat is spectacular. A very caring, knowledgeable, kind doctor that truly cares about his patients. He was able to suggest alternative treatments before going straight to surgery. Surgery was really only discussed when absolutely necessary.
Please see my previous comments. Outstanding!!
Doctor Ernat explained my injury in detail and showed us the x-rays of my shoulder. He gave me options for recovery and did not push surgery. I appreciated the time he spent with us and his friendly manner.
Very capable, friendly and personable surgeon. He solved my knee pain and has given me the opportunity to remain active.
A true professional in every sense of the word, I felt very comfortable with the doctor and his team [TRANSLATED]
Dr. Ernat was super pleasant and explained everything in detail so we understood and never pressured me on a decision. He was part of my decision. Highly recommend
Very friendly. Provided info efficiently and presented me with my options. Made me feel confident in my decision and next steps.
Dr Ernat was thoughtful, thorough, explained everything in detail, and answered all my questions. He educated me about the procedure I had undergone as well as what to expect throughout my course of healing and physical therapy. He was friendly, respectful, and professional. His assistant, Chad, also was kind and professional, and gave me additional helpful information. I appreciated the opportunity to see pictures of my procedure, and get concise descriptions and explanations of what I was looking at. I can't imagine receiving better care, and I'm delighted to be getting my knee back. Thank you again.
Dr. Ernat is straight to the point. I truly appreciate his knowledge and dedication in finding the best solution for me.
Dr. Ernat took the time to explain in detail about my injury, surgical plan, procedures, and post-op care. He answered all of my questions and was receptive to my inquiries.

Very good doctor, does an excellent job. [TRANSLATED]
Dr Ernat is an amazing provider and you will be in great hands. Highly recommend him as a provider
I do not have anything nice to say about this provider. Stand up for yourself in healthcare. You are in charge of your care and your provider should care about you if they are going to do surgery on you.
Dr. Ernat is fantastic. He listens to concerns and explains things in detail. He is very personable and takes the time to make sure you understand everything. I highly recommend him!
Dr. Ernst took the time to listen to me and did not push surgery. He looked closely at my condition and opted for PT instead. It was such a relieving visit as I was certain surgery was headed my way. Thank you, Dr. Ernat.
Dr. Ernat is great. He listens, cares, and includes me on plans to go forward.

I am grateful to Dr Ernat. He seems both well-prepared and caring. We had a pleasant conversation. He listened intently and patiently. He was friendly and realistic in discussing my situation and options. I feel fortunate to have seen a physician who is both so knowledgeable and so kind.
He lifted me to a more intricate specialist for my shoulder after examining me, then explaining what was taking place. Dr. Ernat truly paid off for me because I've spent years in hellish pain in my right shoulder, doctors settling on X-rays that couldn't pull out what was learned in an MRI. My split shoulder is exasperating. This could've been aided to me a couple decades ago. I really needed help. Dr. Ernat sent me in the right direction.

After going to PT a few times, my therapist thought the orders Dr. Ernat provided were a little too prescriptive. I raised this with him and his honest reaction was a little bit of surprise. He admitted these orders might need to be updated and I appreciated his honesty.

Excellent surgeon with a great bedside manner. Listens well and is very empathetic. 10 of 10.
Dr Ernat repaired my torn rotator cuff and bicep. He has been diligent in making sure my recovery is successful and we've met several times to discuss my physical therapy and range of motion. He's a great surgeon and has helped me feel better about having this difficult surgery. He didn't sugar coat what recover would look like so I was prepared.
Dr Ernat was awesome. He managed my rotator cuff repair very well from first consult to my last post-op appointment when he turned me loose. I couldn't have asked for a better outcome.
I would highly recommend Dr. Ernat. He is amazing. He was recommended to me by a friend and from the moment we began communicating, he was helpful, attentive and thorough. My surgery went better than I expected and I am feeling grateful that I found him and am hoping for a great outcome as I get futher along.
Great experience with him
I should carry Dr. Ernat's business cards in my wallet because I can't count how many friends I have referred to him.
Very professional , courteous and helpful, I found the right doctor!
Was in a rush. Had no real information didn't give me specifics of what would be the best course of action for treatment.
Dr Ernat is one of the best I've been treated by. He's very competent, easy to talk with and understand. I highly recommend him and his team.
Dr Ernat is a very friendly guy and did a fantastic job on my extensive rotator cuff repair.

I appreciate his attention and explanations

Justin is more than an outstanding doctor. Best surgical Dr ever! For real I highly recommend him..
Dr. Ernat was the best!
We had the best visit today. Dr. Ernat used the MRI to explain the options for my right shoulder and explain the challenges compared to what we can do on the left. My left shoulder will be quickly repaired by him in a few weeks. We have been through it before with my right. But the chronic problem on the right has no easy answers. It hurts, but my disability doesn't allow me to receive more steroid injections. We don't want to replace it, but another typical rotator cuff surgery is out of the question. Instead of walking away from it, Justin says, "I have an idea." He explained it, told me he was not experienced at that procedure, then said he would consult with his colleagues who have experience doing it. If his idea turns out to be the plan, he will assist in the surgery. I frequently speak about Dr. Ernat to my friends and family and this is why.
Doc is a friendly person. He took time to explain my problem, how he would repair it surgically, and the risks/rewards. I scheduled the repair and have complete confidence in Dr. Ernat.
I'd highly recommend Dr. Ernat. He was so kind and professional. Explained everything in a way that I understood. His team was kind and helpful. My experience was awesome.
Un Profesional Increíble en todos los Sentidos, lo recomendaría con los ojos cerrados para la atención de cualquier Familiar o Amigo que lo necesite

Thank you for seeing me as a person. Offering opinions and answering my concerns and questions

Dr Ernat is the BEST! I highly recommend him to anyone needing surgery or care for an injury. His whole team is amazing and wonderful. They treat you with kindness and respect. I could not ask for better care.
I tell all of my friends about Dr. Ernat. Other orthopedic surgeons should strive to follow his example.
Dr. Ernat and Kyle (his sports trainer) took the time and care to explain what was wrong with my shoulder and the best course of treatment. Dr. Ernat explained what would happen during the surgery and recovery process. He gave me the time to ask as many questions as I had, and that was quite a few. He encourages questions and did not make me feel rushed in any way.
Very nice, knowledgeable doctor.
Dr. Ernat was awesome! I've had many orthopedic surgeries, so speaking from a depth of experience, Dr. E is highly recommended.
Very cool "new skool" kind of doctor. Great communicator and listener. I can't wait to see the scar, through the bandage it feels like he's a real craftsman.
He takes his time, listens to you and explains so clearly the next steps that you have no questions after.
Dr. Ernat is deeply knowledgeable and very caring. We love how attentive he is and how he takes care of my daughter. He is a good listener and has a very calm demeanor.
Dr. Ernat was well beyond my expectations. I'm a former athlete with many injuries and 2 dozen orthopedic surgeries; my expectations are derived from fairly solid past medical care. I can't say enough. I'm going to continue care with him and U of U orthopedics.
I would recommend Dr Ernat to anyone looking for an Orthopedic surgeon who is knowledgeable and very skilled, and also caring. He is confident without arrogance. Communication is excellent!
Dr. Ernat explained everything in such good detail that at the end of my appointment, he asked me for questions and I didn't have any. He made me feel very confident in where I am in the healing process.
Dr. Ernat is the best. I would seek him out regardless of distance. I am a high level athlete that's played football, basketball, skiing, motocross and downhill biking. I thought I'd have lost the ability to do these sports after 2 serious knee traumas, but his expertise and skill has put me on track to return to these at full capacity!! Thanks Dr. Ernat!
He came in and was very approachable. He gave me the information I needed and worked with me to make sure we had a treatment plan that I understood and agreed with and gave me options when appropriate.
He's a great doctor, and took my concerns into consideration

He is literally the best doctor Ive ever been to. I cant say enough good things. I was in bad shape and he got me through the system so I didnt have to wait and immediately everything was taken care of. Hes very knowledgeable, personable , kind, and generous with his time, if I could have him be my doctor for everything that I have to go to, that would be a dream. obviously thats not possible but I highly highly recommend him for shoulder and knee issues
Pleasant but hurried, young and unable to fill my needs, referred me to a surgeon for best results.
Very professional, super informative, was able to get me in right away for surgery. And I'm already after 10 days feeling noticeable improvement without any of the side effects that he is spoke about that could have happened.
Justin always sought first to determine my goals then he presented appropriate options
I expected a lot more than what I got
Dr Ernat really listens and explains what is happening. He makes me feel like I am his only patient when he sees me.
Dr. Ernat is an amazing surgeon. He is always very patient when I need things explained to me. He also values my input, and uses my input when formulating my care plan. I will recommend him to everyone!
I am amazed at how rapidly I was diagnosed, given an MRI and scheduled for/received surgery and post-op follow-up
Un doctor muy amable y se sabe explicarle al paciente el porqu se necesita atencin mdica
Dr. Ernat was listening to all of my comments and concerns very carefully, and he incorporated the information I provided him when structuring a care plan. It brought great peace of mind to know that I was being heard, and that my care was being tailored to my situation.
Justin listened carefully to my concerns and responded with appropriate options for my consideration. He displays a confident but flexible attitude.
A very good experience.. Dr. Ernat cares.
Justin Ernat goes above and beyond in every way. Beside being a great surgeon, he's just a nice guy who cares about people. In my opinion, Dr. Ernat treats his patients the way he would treat a neighbor, friend of member of his family.
Dr. Ernat is very friendly and easy to talk to. He listen to me and always explains my options. He cares about me and my health.
After giving me the options of PT, shoulder surgery or shoulder replacement he supported my decision of PT. Im very pleased with his support and will definitely look him up when Im ready for shoulder replacement.
Surprisingly down-to-earth and a really great guy. He was easy to talk to, listen to everything I had to say and made everything easy to understand.
He takes his time and doesn't rush through your visit. He includes you in formulating a treatment plan rather than telling you what he thinks. He's inclusive and compassionate. I live in Montana and come to the University of Utah just for him. I also pay out of pocket just for him! That speaks volume to the kind of care he delivers.
He was extremely arrogant and smirked if I mentioned any non-operative options. When I asked him what a non-operative protocol might look like, he said, "I can't force you to have the surgery we'd make a treatment plan." Then he hurried out of the room with no explanation of what that might look like and no opportunity for me to ask questions.
Dr. Ernst is simply awesome, and his staff over-the-top fantastic.
Dr Ernat was happy to answer my (many) questions in detail, and gave me really interesting explanations for what we were seeing in my knee. I'm very grateful to have seen him for this appointment.
The doctor and his staff are wonderful.
Incredibly supportive interaction from Dr. Ernat
Dr.Ernat was very kind and patient with me. He took his time explaining things in a clear and concise way. He didn't hesitate to go back over things I didn't understand, and made sure I was comfortable with understanding every aspect of my situation.
He went over all of my options. When I declined the treatment I then asked him if I could get surgery at a later date if I change my mind. He said I would be able to do that.
Dr. Ernat is a great orthopedic surgeon and an even nicer person. He treats his patients like they are his friends, the way he would treat members of his own family. I can't say enough good things about my experience having him as a doctor.
Simply outstanding in all areas!
Excellent doc!
Very good experience
Great encounter
THANK YOU!!!!!!!!!!!
Post surgery, my appointments with Dr. Ernat are a delight. He is just a nice person to meet with and sincere in his desire to have his patients achieve a great outcome.
Again, thank you!!!
Dr. Ernat was able to quickly realize that I've spent a significant period of time in the emergency medical field and therefore discussions of my situation did not have to be simplified down to the most basic layman's terms, which I appreciated.
Explained everything very well. I was super nervous about the whole situation because of the way my previous doctor explained it but He helped me understand
Dr listened very carefully and understood my concerns and goals around the injury
Exceptional service
Very good experience
I really like the way Dr. Ernat goes out of his way to explain things. Comparing one x-ray to another, talking about how this shoulder will be different from the other. (I hit the jackpot with both sides.) He's just a nice guy, talking to me more like a friend than a patient.
I was very grateful that he found that on my MRI IT showed I have a ligament that has torn completely off my shoulder bone that has been causing me extreme pain and said he can fix it!! NOT just put a band aide on it, (Like my last Dr). But to FIX the problem!. This means a lot to me!!
