Patient Testimonials

I started seeing Dr. Arntson in April 2023 for my right knee pain. I had meniscus repair surgery on my right knee in May 2023, and he told me that I would likely need my right knee replaced in the future due to arthritis. Since then, he ended up performing carpal tunnel surgery on my right hand in March 2024, and a total knee replacement on my left knee in November 2024. The left knee had become more painful than my right knee, so I got that one done first. Finally, he did a total knee replacement surgery on my right knee in February 2025.

I would highly recommend Dr. Arntson to anyone looking for an orthopedic surgeon. I was planning my surgeries around life events, like my daughter’s wedding, and would get cortisone shots in between. Dr. Arntson gave advice but understood that I needed to decide when it was best for me to have the surgeries. I trust and appreciate Dr. Arntson so much! He always took time to explain everything thoroughly, sometimes more than once. He has a good sense of humor which I appreciated very much.

Everything he said turned out to be true, even when I didn’t want it to be. For example, Dr. Arntson explained how long the recoveries for the different procedures would be. He told me that they would be long and I shouldn’t get discouraged. Of course, he was right. I am just over a year out from my second total knee replacement surgery. My overall quality of life and day to day living is much better because of Dr. Arntson and his wonderful team!

The Twin Cities Orthopedics staff was very pleasant and professional from start to finish. Dr. Lewis did a fabulous job, beginning with cortisone shots and continuing throughout the journey of having my knee replaced. Having Jordan as my physical therapist made my recovery so much better. She was very pleasant, always greeted me with a smile, and was easy to work with. I cannot say enough about the whole team, and I have already made three referrals to friends and family. Thanks again to the amazing team at TCO!

I cannot say enough wonderful things about Dr. Bircher and his team. I had a total knee replacement in January 2026 and was feeling understandably nervous beforehand. Dr. Bircher immediately put me at ease with his kindness, confidence, and exceptional skill. His caring demeanor made such a difference, and the prayer he offered before surgery was something I truly appreciated. It brought me comfort and peace right when I needed it most

My care after surgery was just as impressive. The staff at EXCEL were exceptional! They were kind, attentive, and encouraging throughout my recovery. The team at Twin Cities Orthopedics were also wonderful and made every step of the process smooth and reassuring. I would highly recommend getting the Berg ice/compression machine as it was incredibly helpful during recovery and made a big difference in managing discomfort.

I also want to mention Jamie in Dr. Bircher’s office, who was amazing to work with. She was always helpful, answered my questions promptly, and went above and beyond with paperwork, especially navigating the new Minnesota paid leave process. I highly recommend Dr. Bircher to anyone considering knee replacement surgery. The level of compassion, professionalism, and support I received from Dr. Bircher and his entire team was outstanding!

Dr. Bircher has tremendous skill with robotic surgery. I had my right knee replaced seven years ago and my left knee in January 2026. I can’t believe how different the healing time has been! He is patient, kind, understanding, and encouraging. He offered a prayer before my surgery which helped put me at ease. I had physical therapy before and after my surgery which was very importance. Renting an ice machine for three weeks made a big difference in my recovery. I highly recommend Dr. Bircher and have already referred him to many of my friends.

I was a patient of Dr. Knowlan during my knee replacement surgery. Dr. Knowlan did an incredible job. I must also mention, my nurses Angela B, Brenna P, Delaney, and Emily. They went way out of their way to accommodate my disability, macular degeneration. I will never forget their kindness and caring nature. They made the knee surgery a pleasant experience. Also, both physical therapists were wonderful as well. Thank you!

I am a huge fan of Dr. James Bircher. I had a total knee replacement on January 14, 2026. Pain aside, which is part of the deal, he set me up for a great recovery. The ROMTech cycle and NICE machine helped, and of course the physical therapy sessions. However, it is Dr. Bircher who made the difference with his brilliance, skill, and altogether lovely demeanor. He even called me once during pre-surgery to explain something which isn’t always typical for a doctor to do. He is exceptional!

I am now eleven weeks out from surgery and my ability to bend my knee is great. My straightening still needs a bit of work. Dr. Bircher has advised me to keep at the PT for continued results, even though he is quite happy with my present status. I ditched the walker after a week and the cane a week later. I was back to using a recumbent bicycle only a few weeks out of surgery. I could not recommend a doctor more highly. I will be booking Dr. Bircher for my other leg, whenever that will be!

Dr. Mittelsteadt and his team are amazing! He replaced both of my knees and preformed two trigger finger surgeries for me. With my last knee surgery, I was surprised at how fast I recovered from the procedure. It’s a tough recovery, but within two months I was back to doing most of the things I did before surgery. The entire team including Annie Drabot, the anesthesiologist, and nurses are extremely knowledgeable and took the time to listen to me. I received the best care and would highly recommend Dr. Mittelsteadt.

I broke the plastic piece of a 16-year-old total knee replacement. After doing some research, I went to see Dr. James Bircher who was local and available. We hit it off immediately and it didn’t take him long to diagnose my problem. I went into the surgery very confident that all would go well. The entire procedure and recovery exceeded my expectations. A big thank you to Dr. Bircher. I’m so glad we crossed paths!

I am 69 years old and had a wonderful experience with my knee replacement performed by Dr. Bircher. He took time answering my questions and his team gave me a lot of information throughout the procedure journey. Their communication truly helped reduce the stress of having a major surgery. I loved that he took the time to talk with me and I never felt rushed. I was able to walk immediately after surgery and now I am four months post-operation. I am doing very well thanks to him and his team. If you are needing a knee surgery, Dr. Bircher should be your doctor!

In 2021 and 2022, I had my left and right knee replacements done with Dr. Eric Busse. He is wonderful! He used robotics for a quad sparing technique replacement. I have had no complications since he has the best surgical skill and outcomes. I have sent family members and friends to him, and their outcomes have been excellent as well. I am a Registered Nurse, so I was very picky about who I wanted as my orthopedic surgeon. I can honestly say I picked the best! Thank you to Dr. Busse and his team!
