Total Joint Replacement



My whole experience before I had my left total hip replacement through my PT has been amazing. Everyone is so friendly! Dr. Schnell is awesome and I can't say enough about Shyanne keeping me on task to meet my goals. My total hip replacement has given me my life back!


I have been seeing Dr. Peter Goldschmidt for more than 12 years and have had multiple surgeries including both hands, both shoulders and many other treatments. I first met him when I came to the Emergency Room with unbearable pain in my wrist. I had had surgery elsewhere and Dr. Goldschmidt discovered my median nerve had been cut. It was 8:00 p.m. and he took me into surgery that very night and corrected the problem immediately. Since that day I have been confident that I am receiving the best care possible with Dr. Goldschmidt. He is someone who stands behind you, goes above and beyond, and truly cares about his patients. He even calls my home to check on me after a surgery — that is something a person never forgets.


Dr. Hanson took time to draw me a diagram and made me feel like the only patient he was seeing the day I was there. Your office has helped me more than anyone else and when I met Dr. Hanson I was thinking I should have just started with him.


Dr. Zamzow did the surgery for my ankle fracture which was very severe. I do not know how he could take such a mess of broken bones and repair them. I recall seeing his hands which are large and yet they do such delicate reconstructive work. Thank God that Dr. Zamzow is my surgeon. I have PT to go through yet but am sure with his expertise and the PT folks I will be up and walking in no time! Thank you Dr. Z.


I just want to thank the OA team for my new hip I received January 22. Everything is going very well. Thank you Dr. Momont!


Dr. Hall stopped me and thanked me for working with a patient from Virginia yesterday. He called her with the MRI results before she got home! She was delighted at the quick service.


I chose Dr. Goldschmidt because I knew he was a skilled surgeon.


I just had my second total knee replacement by Dr. Harms. My first round of physical therapy was with Ann Farley, and I have requested her for round two. Wonderful, competent, kind professionals. Orthopaedic Associates is my first choice for orthopaedic work. They kept me going for 6 years with physical therapy until my right knee hurt at night, then they replaced my bad right knee. Three months later Dr. Harms replaced my left knee. Both he and Ann Farley are superb. Thank you.


I had Dr. Hall do a complete hip replacement. I was in so much pain that I couldn't stand it. He did the hip replacement at 8pm, I got up at 11pm and walked all the way down the hallway with no pain. This is simply the best experience one person could ever have. Dr. Hall is the most amazing guy you'd ever want to meet. He is the best doctor I've ever had in all my life. I was so miserable, he literally saved my life. He replaced it from the front-- I've been walking every day since the day after surgery with no limp. I would recommend him to everybody and anybody, you couldn't have a nicer man in your life. I am honored to have him as my doctor. Thank you.


I wanted to thank Teri for scheduling me to have surgery with Dr. Schnell. You worked your "magic" to fit me in. You did a great job and were always so friendly and kind. Thank you.


Dr. Hall was excellent at explaining the break and showing us x-rays. He even asked about a family event we had going on during our stay.


I was truly impressed with the skill, compassion, and efficiency of my treatment. Thank you to Dr. Momont, Dr. Speer, and Josh Peterson for their superb treatment of my needs. They gave me my athletic way back. I can't overstate how much this meant to me. Thank you.


Love Dr. Zamzow. A great surgeon with a very caring personality.


Had a very information office visit with Dr. Hall. He took the time to explain all of the images on the MRI test. You can tell he loves his job. His kindness shows through.


Dr. Rother and his team did an awesome job for me. Did a total knee replacement and both my shoulders were repaired by total reverse replacements. I'm 82 years old, independent, and work out at a fitness center 3 times a week.


Dr. Hanson is a miracle worker! I am completely pain free.


This summer I tore two tendons in my left ankle. Dr. Reinking did the surgery to mend them. I was on crutches for two months which I didn't like but I followed his instructions and now my ankle is doing well. Thank you Ryan!


I had Carpal Tunnel surgery with Dr. Goldschmidt. Every single person I came in contact with was great! The front desk staff was always friendly and the services you provide are amazing!


I would strongly advise anyone needing a hip replacement or knee replacement to put themselves in the hands of Dr. Rother. He is the best. I originally chose him because I had received numerous recommendations from friends and acquaintances on whom he had performed surgery. They all had extremely positive results, as I discovered for myself when I had my knee replacement. He is a great communicator, a good listener, and a caring physician. I also strongly recommend any one of the exceptionally competent Therapists.


I would like to thank Dr. Reinking for giving me my foot back, and along with that, my health/fitness, my sport of martial arts, jogging and dance. About a year ago he totally reconstructed my foot. It took several months and PT and exercises to heal properly just like he said it would, and it was so worthwhile. I am so pleased. My foot was a mess from all the above mentioned activities. I am able to jog, kick the bags, do my martial arts and fight. I am getting my fitness back. I do not have any significant pain, and best of all, I danced barefoot for two hours at my friends wild and crazy wedding!


Before hip surgery my pain and movement was terrible. Dr. Harms gave me back my life. I had no life before my surgery. After my surgery i was able to walk down the aisle for my son's wedding and be pain free.


A special thanks to Orthopaedic Associates of Duluth including office staff, PT, PAs, and especially to Dr. Momont for my right hip replacement. I am able to walk pain free and enjoy getting back to tennis, competitive table tennis, mountain biking, hiking, and enjoying the great outdoors. I try feel blessed to stay active again. Thanks for all you do.


I had surgery to repair my torn rotator cuff on January 5. Dr. Harms did an excellent job; the surgery was a complete success. I am so excited to be free of pain and be able to get back to my active lifestyle! Thank you again Dr. Harms and also to the staff at Duluth Surgical Suites; I received top notch care and everyone was very compassionate and professional!


I had hand surgery on September 11 to have my basilar joint reconstructed. Pete Goldschmidt performed my surgery at the Lakewalk Surgery Center. My surgery was a complete success and my scars are barely visible. I have had Carpal Tunnel surgery on both hands, an elbow repair and a knee replacement all done by Pete Goldschmidt and Michael Momont. My husband has also been treated by them as well. I highly recommend Orthopaedic Associates for any of your needs. Very professional and friendly to their patients.


In July I had a pretty bad fall where I severely broke my left foot AND my right ankle. I needed emergency surgery on both, with plenty of hardware to keep all the broken bones together. Dr. Hendricks was one of the most compassionate doctors throughout the entire ordeal, and spent time discussing my situation during the follow up. I didn't feel rushed, I felt that he actually cared. I was told that because of the complexity of the breaks, it would most likely be a few months before I could bear weight on either leg, and much longer before I could walk again unassisted. He did such an amazing job with the surgery that I was able to stand at 6 weeks, and walk unassisted by 8 weeks. It's just now 13 weeks post-surgery, and I am almost completely back to normal. I am so grateful to Dr. Hendricks and the staff at Orthopaedic Associates!


In May of 2015 Dr. Schnell replaced my knee joint. I couldn't be more pleased with the care I received. A year and a half later, everything is great! No pain! What a blessing Dr. Schnell is to our community! 


On April 22nd, my life changed in a matter of seconds. I suffered an extensive knee injury after falling from my horse. I ended up with complete tears of my patellar tendon, MCL, ACL and two tears in my meniscus. I was terrified after the ER doctor told me that I needed reconstructive surgery of my left knee. I ended up getting an appointment with Dr. Harms just a couple days after my injury and he scheduled surgery immediately for the following day. I am now 4 months post op and walking on my own. Dr. Harms has been part of the entire process, communicating with me and my physical therapist to decide the best treatment plan for me. I can't thank Dr. Harms enough for everything he has done. Although I still have a long road of therapy, I am starting to feel more like myself again. Dr. Harms is a miracle worker and I highly recommend him! I wouldn't be where I am today if it weren't for him! Thank you!


I just have to put in a super plug for one very special doctor named Dr. Pat Hall, of Orthopaedic Associates in Duluth. He comes to Burnett Medical Center Mondays (weekly with an occasional exception.) Anyway, I had knee arthroscopy at BMC a few weeks ago, which was an easy procedure and I was well cared for. But to make a long story short, I developed more knee pain a week or two after the surgery (not in an area of the surgery) which has gotten so difficult that walking has been a real trial. So, I called him this last Tuesday and he urged me to drive up to Duluth today (rather than wait for Monday) so he could try to help me out (I leave next week for Mongolia, which he knows). I did that today and got almost immediate relief from a knee injection which should last 4-5 months, long past the time I'm back home from my trip. Dr. Hall is so kind, gentle, caring and has excellent skills, so he's got my vote for doctor of the year, at least at the Carlson household! Thank you, Dr. Hall!


Dr. Hall literally came to my rescue when I had an accident while hiking in Colorado. He splinted my broken ankle using a diaper changing pad, granola box, and hammock straps; he helped the group of people carry me down the mountain; and he stayed with me until we made it to the ambulance. His professionalism and compassion to a total stranger on a hiking trail speak volumes about his character.


I am so thankful for Dr. Reinking. I am 8 months post ankle surgery; I am able to walk, lightly jog, and wear a low heel, all without pain.  I never thought I would be able to do any of these three again without consequence. I feel like I got my life back! I would recommend him to anyone dealing with ankle/foot pain.


 I have been a patient of Dr. Zamzow for over 20 years. He has replaced both of my knees and my right hip so far. I would not hesitate to recommend Dr. Zamzow to any of my friends. He is always there to answer any questions and takes a personal interest in his patients.

T. Fitzgerald

Thank you Dr. Schnell for your dedication to the field of orthopaedics. We appreciate your honest opinions and concern for our family. We are grateful to have found you to help with all of our orthopaedic needs. Thanks again.


Thank you for your compassion and education today for my shoulder. I appreciate your thorough explanation and plan for my care. You are so approachable and I value that in my surgeon. Thanks again!


My whole experience for a total knee replacement was so very positive, from my initial appointment with Dr. Rother, the Rainy Lake Medical Center that enabled me to have this procedure at home, no travel! Follow up appointment with his associate, and the end of the month again with Dr. Rother. Thank you Orthopaedic Associates for the traveling and skill you bring to our community.


I have had ankle and shoulder surgery with Dr. Zamzow and he is the best orthopedic doctor anyone could have. His compassion and caring is outstanding. Just recently went to Dani in the therapy department after surgery and she was excellent and helped me greatly with her expertise. I would not hesitate to recommend the doctors or staff to anyone.


I broke my femur and dislocated my knee my freshman year of high school. Dr. Momont went in and repaired my knee and femur. With the job he did and the rehab after, I was able to play 3 sports the next 3 years of highschool. I was even able to play 2 years of college baseball on scholarship. Thank you Dr. Momont!


I saw Dr. Patrick Hall a couple weeks ago and was very pleased. He seems concerned and is very easy to talk to. I've always had a good rapport with your doctors.


I was so skeptical about surgery for the plantar fasciitis that I've dealt with for almost 2 years. Sometimes it goes away on its own, but I couldn't live with the pain and function normally any more. My biggest thanks to Jesus Christ for His healing hands and Dr. Ryan Reinking for his confidence and expertise. I felt like I was in the most trustworthy hands.

Today, I am 2 weeks post-op and completely free of the pain that was disabling me. I do have sugucal and incision pain which is minimal, but I feel like I have my life back. I don't think Dr. Reinking has a clue what impact this has on the rest of my life.


Gary Andrews has been wonderful to my dad. He has shown great compassion and patience working with my dad throughout the years and now during his knee replacement. Thanks Gary!!


About 8 weeks ago I suffered a broken ankle and broken tibia. Dr. Hendricks was my surgeon at St. Luke's and I continue to follow up with him. He has taken the time each and every time I visit to explain what's happening, the healing process, why to wait and how long to wait before I can be "normal" again. He is the kindest doctor and I would be lost without someone like him during this ordeal. Your expertise and professionalism and your extreme kindness and that of all your staff, and your assistant, Laura, is overwhelming. Thank you.


I just wanted to mention how pleased I was with the whole knee replacement process I experienced earlier this year with Dr. Momont and staff. The rehab and PT process with Kim was simply amazing. She was knowledgeable, personable, encouraging and patiently answered seemingly hundreds of questions during the whole process. Thanks again for all of it.


A few years ago my daughter broke her wrist in several places, it was iffy if it would ever be normal again. Dr. Peter Goldschmidt, MD did an excellent job of mending the bones, and she has full use of her wrist.


Dr. Peter G. Goldschmidt fixed my broken finger and did a good job. I am glad I found him right on time. He helped me so much and I love him for that. I recommend Dr. Goldschmidt 100%.


October 29th 2014 was life changing ... at 49, and severe degenerative OA in both knees. Doctors Goldschmidt and Zamzow replaced both of my knees, and one month later I can still say it was the best decision of my life! Teamwork at it's finest! And, as many times as I've been asked ... YES, I would do it again! Thank you for giving me my life back! I am so very grateful and thankful to you and your Hermantown therapy department!

Sandra Willis

I am ever so thankful to Dr. Peter Goldschmidt for doing two successful surgeries on both my thumbs – basilar thumb surgery. He explained the surgery beautifully so that anyone could understand. He is down to earth and is very easy to talk to, which is very important for a patient/doctor relationship. And, answers all questions! I rate him 5 stars!

Peggy Fabish

I had an Anterior Total Hip Replacement on 1/17/2014. Dr. Rother has given me my life back. I have no more pain and my limp is gone. I am so happy I chose him to perform my surgery. He has a kind and gentle manner and is an excellent skilled surgeon. Thank you again Dr. Rother.


I had a shoulder manipulation done in November of 2008. The procedure went very well and I would highly recommend the Orthopaedic Associates and Lakewalk surgery center.

Joseph Jagunich

Dr. Rother successfully replaced my arthritic hip on 12/2/09 with the minimally-invasive Zimmer 2-Incision procedure. I am greatly impressed with Dr. Rother's surgical skills, as well as his bedside manner and follow-up. I'm totally pain-free!

Donna Hill

I had a total right hip replacement done by Dr. Schnell on 3-2-10 and have been completely satisfied with the experience start to finish. Thanks, Dr. Schnell, for giving me my life back!

Denis Holman

At the risk of sounding accident prone, I have seen Dr. Robin W. Hendricks on 4 different occasions. He repaired my MCL, ACL, PCL and AC shoulder separation. Each time I knew I was in excellent hands and healed quickly. I highly recommend Orthopaedic Associates because of their outstanding level of care and professionalism.

Dawn Terwey

I am very pleased with Dr. Rother's surgical skills, and bedside manners as well. His professionalism is incredible. His way of getting rid of the pressure and pain is "WOW"!! I would recommend anyone to see him.

William E. Tolrud

Dr. Hall did an excellent job on fixing my fractured Femur after I fell. To get the alignment fixed and stabilized required a technical mind and a steady hand. I wish to thank him and the staff for doing such a great job.


Dr Schnell – can't say enough about how great this guy is. Professional, personable, knowledgeable, skilled. He takes time to talk and figure out what is what and what needs to be done, then takes care of it. Awesome experience, even in these times.

Juanita Whitebird

I have received medical care through different physicians at Orthopaedic Associates. The advice and treatment have been the highest quality. I have utmost faith in their medical knowledge, treatment and surgery skills. The excellent patient care received by doctors and staff is of high quality. I could only wish all medical facilities could match that of Orthopaedic Associates. My heartfelt thanks to all who have ever given care to me.
