I was hit by a car in a parking garage in 2012. My left knee meniscus was heavily damaged and was cleaned up microscopically, however I was told at that time that I would likely need a knee replacement before age 65. After moving to MN, I transferred care to Dr. Arntson at TCO. Due to arthritis, my knee would periodically swell, which was very painful. I had it drained with corticosteroid injection which worked extremely well for a number of years but, as forewarned, it eventually stopped being effective.
I had a total knee replacement, spent the next day at Mercy Hospital, and after my second PT session I was able to return home. The first couple of days were rough (pain wise). Within 2 weeks I was able to walk unassisted. Within 6 weeks I was able to engage in most of my prior daily routine. Continuing PT and exercise, I anticipate being better than I have felt in a couple of years. Thank you TCO, Dr. Arntson, Megan Nelson (PT), and Bri Lund (PA)!

I had a knee replacement with Dr. Arntson on June 2, 2020. The surgery went so well, I cannot say anything bad about the care I received from Dr. Arntson and his team. It was so good and I get to go back to work on July 13. I feel great.
February 24, 2020
Right after surgery I felt so much better, for I had so much pain before. The week before surgery, when I had to go off all NSAIDs and anti-inflammatories, was very painful. After surgery I didn’t need any narcotics, just hydroxyzine for 7 nights while at home. I am now walking without pain- a little numbness by the incision and a little pain up the buttocks after doing exercises, but do not need to take anything for it. My hip has felt so much better since surgery. Thank you so much.

I am a 79 year old patient of Dr. Arntson and have been for about 6 or 7 years. I had been struggling with knee problems for several years, the cartilage had worn away on the insides of both knees. In the beginning, Dr. Arntson started me on Synvisc shots in the knees which worked well at the time and kept me pain free for about six months. After about 3 years, the Synvisc no longer worked and Dr. Arntson started telling me the insides of the knees were now bone on bone. He tried to tell me it was time for knee replacement but I kept holding off thinking they were close to making stem cell therapy work for the knees which would naturally grow new cartilage in the knees. Dr. Arntson, as you have seen in other reviews, is a kind and caring man, pleasant to talk to, who explains everything to you in depth and gives you his best opinion but leaves the decision up to you. I then started getting cortisone shots for the next 3 years, which only helped for about 2 months between shots. Finally they got so bad I talked with Mayo Clinic about the stem cell replacement and they told me that they could replace stem cells and grow cartilage in the knees but had problems with getting blood to the knees to keep them alive and growing. They would only last several months. Finally Dr. Arntson convinced me to do partial knee surgery, which replaces the joint on the inside knee bone and leaves the rest of the knee alone. He told me he would do both knees at once and I finally agreed. It has been almost 5 months since the surgery and I couldn’t be happier with the surgery and Dr. Arntson. I am doing everything with these new knees – biking, golfing, dancing, bowling, and on and on with no pain. I will say, however, that I constantly and religiously did my therapy after the surgery and continued it at home plus I am not overweight, I try to keep myself in shape. I believe that makes a great deal of difference. Thank you so much Dr. Arntson.

It’s been a year now since my PKR surgery and my knee looks and feels great! Dr. Arntson is kind, caring and well respected by patients and co-workers. Got questions? He’ll answer them all. He seems rather quiet but tells it like it is. Its ok if you’re not ready for surgery. He will address your fears and maybe you will change your mind, as I did. I look forward to eventually having two good knees with a little help from my favorite surgeon. Dr. Arntson is simply the best and I hope you’ll visit with him to see for yourself why he’s highly recommended.
December 19, 2019
Right from the start I knew I was in good hands with Dr. Arntson. He told me everything I needed to know about my right hip replacement surgery and answered all of my questions. I felt confident and positive about Dr. Arntson and the surgery, which I believe helped the outcome. I feel great! I felt good right after the surgery and it only improved as time went on. Here at the 4 week mark I have no pain and my mobility is amazing. This surgery with Dr. Arntson is near to miraculous. I have my life back and I know shortly I will be able to do all the things I love to do. I know that if I need this procedure in my left hip in the future, Dr. Arntson will be my go to doctor. Thank you for giving me my life back!
December 10, 2019
Dr. Arntson is a very humble but extraordinary doctor. His ability to work with patients and together come up with a plan to fit their needs is remarkable. I was able to plan my surgery at the best possible time for me and my knee. After my surgery, I had no pain. That’s right – no pain. The only pain I had was when I did my physical therapy.
Dr. Arntson was careful with the procedure, making sure that I did not get an infection. I searched and researched a long time to find a great surgeon, and I found one. I will recommend Dr. Arntson to anyone who needs a great surgeon. And he’s Norwegian!
December 10, 2019
Very happy with my results from my anterior hip replacement with Dr. Arntson. Surgery went well, feeling much better and getting around easier. A real life saver, thank you so much.
November 14, 2019
This is just to let you know how pleased I am with the surgery. It is so good to not experience pain, limping, etc. anymore. Dr. Arntson was superb! He takes genuine interest in the patient and also takes time to address any question without making one feel rushed. I chose Dr. Arntson because a friend of mine had him do two shoulder replacements and she couldn’t say enough nice things about him. I have suggested him to several of my friends and two are for sure going to see him. Thank you for a “10” experience. Also, I am very grateful for the kindness shown by the Mercy Hospital staff including the doctor of anesthesiology and his assistant. Both were very understanding and kind.
November 6, 2019
Three years after my first total knee replacement went awry, I have now had a highly successful replacement — of the replacement. Dr. Arntson’s reputation in the community for being a gifted surgeon made my decision easy when selecting him. What came as an unexpected bonus was that his kindness and underlying sense of humor during office and hospital interactions with him brought me joy.
November 6, 2019
I am so pleased with my surgical experience. Facing a total hip replacement can be scary. The experience went so much better than I expected. I know every person is different but, at the end of 6 weeks, I have no pain or discomfort. Dr. Arntson – thanks for your skill and encouragement.
September 25, 2019
Everyone at TCO was the best I could ask for. They took great care of me, like family. Also, everything was right there for my recovery. I will be getting my hand done next. Thank you all and see you again soon!
I am overjoyed at the outcome of my surgery! I suffered for quite awhile before realizing I had a fractured hip. Dr. Arntson was amazing during the whole process. I am 6 weeks out from surgery and my hip feels brand new.
August 21, 2019
Dr. Arntson did a remarkable job assessing my broken hip that resulted from a fall on ice while playing hockey. Dr. Arntson and his surgical team were outstanding in their preparation and the procedure of my hip replacement. I feel very fortunate that Dr. Arntson was on call at Mercy Hospital in Coon Rapids, MN. As a result, with Dr. Arntson’s fine work and dedicated rehab, I have regained full function of my hip and could not be more satisfied.
August 19, 2019
I feel so very fortunate in having Dr. Arntson – he is so compassionate! He took care of all my needs and worries. I voiced my opinion at the hospital and he is so very well liked and respected there.
August 12, 2019
Received a cortisone shot in November from Dr. Arntson which really helped the pain in my hip, then proceeded with anterior hip replacement surgery on my left hip in March. Surgery went well and I was out of the hospital in 2 days. Did at-home exercises and took pain meds – after 2 weeks only needed Tylenol for pain and continued home exercises for 2 months or so. Now well healed, pain free – right choice for me.
June 28, 2019
On May 23rd 2019, I had my left hip replaced by Dr. Arntson through the EXCEL joint replacement program. He has an excellent bed side manner and is truly a compassionate man. I was apprehensive at first but after meeting him and his team, I knew I was in good hands. Dr. Arntson and his team are true professionals. Through my journey, pre and post-op, the whole team was awesome. I highly recommend him, TCO, and his staff for your surgical needs.
May 20, 2019
Dr. Arntson is an excellent doctor, very informative, excellent bedside manner. My whole experience with knee injections and a knee replacement has turned out very well and healing faster than normal because of very good care all around!
April 17, 2019
After a bad experience with 2 knee replacements and years of pain from another physician, I went to Dr. Arntson with hopes he could help me. He has done a great job revising both knees and making them pain free. I would recommend to any patients to see Dr. Arntson!
April 17, 2019
Dr. Arntson was amazing and so helpful before, during and after my surgery. He was thoughtful, thorough and set me at ease that a hip replacement was the right thing to do! I was in severe pain before my surgery – worked out 5 days a week in pain. 6 months later and I workout pain free, have no pain and I’m living life to the fullest. It was a blessing! Dr. A is the best!
April 3, 2019
I was surprised that I was released from the hospital only 36 hours after having my left hip replaced by Dr. Arntson. There was no significant pain or discomfort after the spinal blog wore off. I attempt to do 90 minutes of water aerobics 5 days a week. There have been no negative outcomes or consequences. I have noticed an increase in mobility mirroring someone with no artificial hips.
April 3, 2019
Dr. Arntson performed a left hip replacement for me after I fell and broke my hip on ice. I was able to begin waling the next day with a walker. Within 2 weeks, I was walking on my own without a walker. Now, six weeks later, I am functioning normally with only a slight limp. Getting stronger each day. I am grateful to Dr. Arntson for putting me back together so well! Thanks!
I have very little pain now, and am looking forward to spring/summer activities soon! My dog is happy now that we can go for walks again!
March 8, 2019
I had to use a cane, wheelchair and walker before I had my knee replacement. I had taken shots as long as I could to get relief from the pain. I asked for the surgery and I am so glad I did! It wasn’t long after the surgery that I could enjoy taking steps without pain. My knee works fine! Looking forward to summer as it will be 1 year in July that I had my knee replaced. I am also looking forward to resuming garding and walking without pain and now with a stronger knee. Dr. Arntson explained everything to me. He always had time for my questions and concerns. His gentle spirit always calmed me.
March 8, 2019
I had a left hip replacement through the TCO EXCEL Program done by Dr. Arntson and within a few weeks, I had no use for a walker or cane. The surgery was perfect and Dr. Arntson was always there if I had a question or a concern. I totally recommend Dr. Arntson!
February 1, 2019
I recently had a total knee replacement through Twin Cities Orthopedic and the EXCEL Surgery & Recovery program. My surgeon was Dr. Zachary Arntson, I could not be any happier with the results. I was so scared to do this surgery but it had to be done. I could not walk without being in a lot of pain. Dr. Arntson was compassionate, very informative and really listened to my concerns. After 5 weeks I am going back to work, It feels so good to be able to walk without pain. If you are thinking about doing a surgery soon I highly recommend meeting with Dr. Arntson you will not be disappointed.
January 4, 2019
My knee deteriorated quickly after injury and arthritis. Deciding to have a new knee was not an easy decision at age 53. Having a total knee done by Dr. Arntson was an excellent choice and experience. My only regret is that I didn’t do it sooner. I stayed two nights at Mercy, which was a good experience. Four weeks after surgery, I felt ready to go back to my nursing job which requires walking and standing most of the day. I actually went back at six weeks which worked out well. Now it has been three months and I feel like I can do everything I want to do (except kneel on my knee).
Thank you Dr. Arntson
November 26, 2018
This was the second hip replacement. The first replacement (done by another provider) was good. This one by Dr. Arntson on my left hip was great. I recovered faster with less pain than the first. Sincerely thankful for the kind care.
November 12, 2018
I am very happy and pleased with my anterior total hip replacement surgery and the aftercare. Dr. Arntson is a great surgeon who really cares.
October 18, 2018
I had a very painful left knee, I could not walk without pain or a limp. I went to Twin Cities Orthopedics and saw Dr. Arntson. He found that I had bone on bone in my left knee. Dr. Arntson helped me understand the problem, he was very compassionate and caring. He explained that I needed my knee replaced. Dr. Arntson did the surgery at Mercy Hospital and he did a wonderful job. My knee is healing wonderfully and I am able to walk without pain or a limp. My follow-up appointment went very well, he explained everything about the healing process. I would highly recommend Dr. Arntson, he did a wonderful job on my knee and I now walk without pain and up-right. Janet P.
October 15, 2018
Dr. Arntson replaced my left hip joint 5 months ago with very good results. Before the surgery I had a lot of pain and trouble walking more than 100 yards. I trusted him so much that I had him perform surgery on my right wrist for carpal tunnel 6 weeks ago. Both surgeries were successful. He is a caring professional in and out of the surgery suite. He is also a sharp dresser when not in scrubs.
August 3, 2018
Dr. Arntson performed a shoulder joint replacement for me. The surgery went perfectly, and I had no pain following surgery. Dr. Arntson gave me his full attention whenever I had an office visit and I was treated very professionally. I will be having my other shoulder joint replaced in the fall, and I actually am looking forward to it. Of course, I will have Dr. Arntson doing the surgery.
August 3, 2018
Dr. Arntson diagnosed my shoulder problem and operated on it. The surgery was a success, I have no pain and I feel great! He did a great job and I’m glad I went with Dr. Arntson.
August 3, 2018
Being 53 and living an active lifestyle include hockey, hunting and a physically demanding job, I started to feel pain and loss of mobility in my left hip. A visit to a surgeon was in order. Upon leaving the consultation with a different doctor I felt like I was keeping him from something more important than me. That was not the case with Dr. Arntson. Upon leaving I knew he was going to be my surgeon. A total hip replacement was performed with the anterior approach. Amazing!! Within 8 weeks I was back to work doing my job delivering beer and ready for the fall hunting season not babying my new hip at all. I highly recommend Dr. Arntson and his staff so much that when my right side is to be replaced he will be performing the surgery.
August 2, 2018
Dr. Arntson was honest, informative and an excellent surgeon. He was clear in the objectives my partial knee replacement would achieve. He made no outlandish promises of a “fountain of youth.” I am relatively young at 53 years old and wanted a procedure that was viable to help me enjoy my work/recreational life but also allow flexibility if 15-20 years down the road if I needed more surgery.
The Dr. Arntson and staff are excellent with providing information you truly need and respecting the educational background you also possess (I worked in physical therapy 18 years and am currently Hospice RN). I am post-surgery day 3 and have not used any pain medications and have minimal swelling. Today was also my first day evaluated by TCO Physical Therapist Eric who is also eager to listen to my goals and questions following surgery. So far 6 stars out of 5!
I have been employed in Healthcare for 27 years and never experienced this level of world-class expertise combined with people who truly care! Dr. Arntson and TCO have assembled a unique team of people dedicated to improving my work/life balance.

I have been dealing with osteoarthritis for a number of years. When I finally decided to do something about it, I had Dr. Arntson recommended to me. I couldn’t have asked for a better doctor in every way. He is kind, a good listener and really cares about his patients. But, most important, he is an excellent surgeon. I have had very quick recoveries in both hips as his surgery experience is the less traumatic anterior hip replacement. Thank you Dr. Arntson, from the bottom of my heart. I look forward to better days ahead.
June 7, 2018
Dr. Zachary Arntson was my fabulous surgeon for my full knee replacement in April 2018. During my year of developing pain, Dr. Arntson listened and explained with devout compassion. When I decided to go ahead with knee replacement he explained everything thoroughly and didn’t sugar coat it. He made sure my expectations were in line regarding this challenging recovery. He did a brilliant job replacing the joint. And, because I have followed his care instructions to the letter, I am walking pain-free in just 6 weeks. Of course there is continuing recovery, but my year-long battle with bone-on-bone arthritic pain is history. May I also say that the Mercy Hospital staff and my physical therapists at TCO (Seth and Jared) have been outstanding! I couldn’t be happier with my results. If you need a knee consultation, please don’t wait. Start by seeing Dr. Arntson and then get it done and get your life back!
June 1, 2018
Dr. Arntson and the team at Mercy gave me a new hip 2 weeks ago. The first meeting with him was very positive. He was calm and thoughtful during my visits. He thoroughly explained the whole procedure to me and I left knowing he is a great surgeon. Dr. Arntson told me I was a good candidate for an anterior total hip replacement. The evening after my morning surgery I was walking with a walker and no joint pain. The next day he came to my hospital room to check on me and give me some guidance. He explained what my responsibilities for a full recovery would be. His follow up call a week after surgery was surprising but very appreciated. I am thankful to him and the people at Mercy for their skill and kindness. I would recommend Dr. Arntson to all my friends and family.
May 9, 2018
In November 2016, I underwent a total knee replacement by Dr. Arntson. I could not be happier with the results. I felt that through the entire process Dr. Arntson was there for me. I followed all of his post op instructions, attended my prescribed therapy appointments, exercised at home and today my knee is pain free. I actually took a two week cruise just a mere 8 weeks after my knee replacement. I was able to take walking tours, go up and down steps and resume my normal activities by that time. Plus there was only minimal scarring, so I was able to wear shorts. Dr. Arntson is a talented doctor and surgeon. I still need to have a total knee replacement on my other knee and when the time comes I will be seeing Dr. Arntson for that too. My husband tore his meniscus in a fall during the winter and Dr. Arntson repaired his knee too! My husband was back to work in 4 short days! We both agree that Dr. Arntson is OUR orthopedic go-to.
March 28, 2018
I struggled with hip pain for over 1 ½ years. I could hardly function, walked with a severe limp and I could not get on the floor to play with my grandsons. My primary care physician determined that I had severe osteoarthritis in my left hip. The first orthopedic surgeon I met with said we could do steroid injections to reduce and potentially eliminate the pain from the osteoarthritis. The injections were a treatment for the symptoms but not a “repair”. This doctor also said that we could do a posterior approach hip replacement. I have family and friends that have had hip replacements. All of them told me to have an anterior approach hip replacement because the recovery is faster and less painful. I chose to get a second opinion and look for a surgeon that did the anterior approach arthroplasty. Dr. Butterfield from TCO, who repaired my shoulders, recommended Dr. Arntson. Dr. Arntson did a fellowship in North Carolina where he had been trained in Anterior Approach Total Hip Arthroplasty. My hip replacement experience with Dr. Arntson of Twin Cities Orthopedics was excellent. 2 hours after waking from surgery, I was walking to the bathroom with a walker. I work in medical devices and Dr. Arntson was very direct, clear and accurate on what he would do, how it would be done and what the post-surgical procedures would involve. All of it has come true and I am very happy with the outcome. I only needed crutches or a cane for 2 weeks after the surgery. I am pain free and my limp is almost completely gone.

Dr. Arntson’s Checklist:
Listens – CHECK
Does Not Judge – CHECK
Knowledge – CHECK
Provides Options (when appropriate) – CHECK
Straight Forward – CHECK
Compassionate/Cares About His Patients – CHECK, CHECK, CHECK
Above is just a short list of reasons I would recommend Dr. Arntson to anyone struggling with making that all important decision to move ahead with joint replacement. At age 48, I had my first total knee replacement by another reputable surgeon (now retired) with Twin Cities Orthopedics. Based on the success of that replacement, 5 years later I knew I needed the other knee replaced. Sticking with TCO, I had my left knee replaced in November 2015. 6-months post-op my knee just didn’t feel right so I continued with visits to my doctor until finally at the 1-year post-op mark I went in for arthroscopy, resulting in the removal of minimal scar tissue. Still not confident things were right, my doctor offered to scope again, but made the recommendation I see Dr. Arntson for a 2nd opinion.
My initial consult with Dr. Arntson resulted in his giving 100% to listening to me share my issues of both knees and replacement history. Following a line of questioning, checking the stability, etc., of my problem knee he informed me that with everything described and done to that point it was a “red flag” that the new joint of less than 2 years needed to be replaced. Needless to say I was shocked, and disappointed. Options were provided and all tried (lab work to rule out infection, injection, another scope). After all was said and done, and the shock of a revised replacement wore off, I knew what needed to be done and felt very prepared to go through another replacement; more importantly, I was very confident that Dr. Arntson was going to make this revision a success.
In early October 2017, the revision went ahead at Mercy Hospital. Unlike any other past surgeon, Dr. Arntson visited me each day I was in the hospital to ensure all was going well, changed the dressing and provided me information about the procedure itself. My first day of therapy in the hospital amazed both myself & my therapists. I made more progress in the first few days than expected and certainly far sooner than in the past! After 2-3 weeks I was experiencing some rather severe calf pain so Dr. Arntson ordered a scan to rule out a blood clot, which thankfully turned out negative. He called me at home with the results, as well as followed back around with another phone call a few days later to see how I was doing. I am now at week 5 post-op and doing very well. Without a doubt, this “Rolls Royce” of new knees is going to get me back to my bowling average in no time at all. Thank you to Dr. Arntson, his surgical team and Mercy Hospital staff!
It would be remiss of me if I didn’t also give kudos to Kristen V., Dr. Arntson’s patient care coordinator! Kristen, as a supervisor in a different line of medical profession, I know just how tough some days can be. I truly appreciate all of the help you provided me before, during and after my surgery.
July 31, 2017
Let’s hear it now, three cheers for Dr. Zachary Arntson and Twin Cities Orthopedics (TCO) – HIP HIP Hooray, HIP HIP Hooray, HIP HIP Hooray!
I first met Dr. Arntson on June 14, 2017. He walked into the room and began his initial exam, asking questions and listening to my answers. I sensed a feeling of confidence in this young doctor that was tempered with an abundance of humility. I knew he understood the pain I was in, and he quickly put the steps in motion for a total hip replacement. He explained the surgical procedure (direct anterior approach) and its associated risks while reassuring me at the same time that I would be in good hands. I left the clinic that day feeling like there was finally a light at the end of the pain tunnel.
My surgery was scheduled for July 10th at Mercy Hospital in Coon Rapids, MN. I was in the pre-surgery room waiting for Dr. Arntson to arrive for a last minute check in when he walked in to sign my right hip. We chatted about his recent vacation (my wife and I had been to the same place a few months before) and then it was time to head for the operating room.
The rest, as they say, is history. True to his word, I was up walking the halls WITH NO BONE ON BONE HIP PAIN that afternoon! I was discharged the next day and have continued to improve. This procedure is the best – no follow up physical therapy other than walking everyday and doing the exercises sent home by the physical therapist.
I can’t say enough about the staff at the TCO Fridley clinic. Courteous, friendly and professional, there was hardly any wait time for appointments. As for Dr. Arntson, his sly smile is disarming and his sense of humor immediately puts you at ease. His calm and quiet confidence is surpassed only by his humility. He has been blessed with excellent surgical skills which he uses to serve others. If you need a hip replacement, this is the guy you want on your side.
Thank you, Dr. Arntson, for making the quality of my life better.

I have had problems with my knees for 15+ years. I had a torn meniscus, acl, mcl and a lot of arthritis. Dr. Bocklage and Dr. Kraft have both done surgeries on me. I called to make an appointment with Dr. Kraft but he had retired. The nurse suggested Dr. Arntson. When I first met him he was very nice and helpful. He explained all the options to my husband and myself and answered all my questions. I decided on a knee replacement. I have heard many horror stories about the pain and it didn’t work and so on, but I felt very confident with Dr. Arntson and he reassured me that everything would be fine and I would be well taken care of. I felt very calm going into surgery and knew that he would do a great job.. He talked to my husband after surgery and said everything went well. From the time I was in recovery throughout my hospital stay (3days ) I had very little pain. The nurses at Mercy were very nice and were always there when I needed them. Dr Arnston came on the second day and removed the bandages. I was really shocked because it looked so good. Lots of swelling and pretty colors but the incision looked great. He did a great job.
Dr. Arntson and his staff have all be wonderful. He is an amazing surgeon, very kind and caring. I would recommend him to everyone 100% I would also like to mention the physical therapist at Mercy. Denise is great and my two outpatient therapists, Seth and Jared. They push me to do what I need to get better. I am doing great and with a little more time I’ll be walking and hiking the way I use to.

I am a 52 yr. old who suffered a meniscus tear on my right knee while working out. I just had knee artroscopy surgery and am extremely pleased with the results. I was able to bear weight on my leg immediately. I had minimal to no pain. I was back to walking around lake Calhoun within days. I recommend Dr. Arntson very highly.

May 30, 2017
Dr. Arntson performed anterior total hip replacement on my left hip at the end of March. I was amazed at how well I felt when I was able to walk on it only several hours after surgery (with the aid of a walker). I went home the next day. The PT at home was “walk, walk, walk,” and that’s exactly what I did. In less than a week I was using a cane to help get around. I had no pain in that hip the entire time. At my two week checkup Dr. Arntson told me that I could move my leg in any direction I wished, including crossing my legs. Something I wasn’t expecting to be able to do for another month or two. I was amazed at how there were no restrictions after two weeks. Walking, stairs, stationary bike, etc. only limited to my tolerance for any activity. That made a difference in healing. My recovery time was so much less than I thought it would be.
Dr. Arntson is very kind and caring. I had other health issues of which he was very accommodating, making sure I would be as comfortable as possible. I appreciated that very much. Sometimes it’s the little things that help make the big things not seem so frightening. I had no fears going into surgery, I felt I was in great hands, and I was. He is a considerate and compassionate person. His concern is sincere. He listened to all of my questions and respectfully provided me with answers to each one. He has a great beside manner and a wonderful sense of humor.
Words can not express how much I appreciated such a kind, caring, compassionate, skilled and experienced surgeon. My experience was remarkable and the care I received exceeded my expectations. I highly recommend Dr. Arntson.
Oh, the places I can go and the things I can do!

I was kicked by a horse on February 14th and ended up with a tibial plateau fracture. I could have opted to “fix” that or have a knee replacement, Dr Arntson was very informative about the pros and cons of my options and i scheduled a minimally invasive knee replacement with him on March 21st. I was insistent on the best care as I was determined to be back riding horse again for the spring, summer and fall season. I was not disappointed. The surgery and the therapy all went well. I drove myself to my first physical therapy session (this was a right knee replacement) one day short of four weeks after my surgery. This is not recommended but my ride to therapy fell through. I was able to quit the prescription pain medication less than 2 weeks after surgery and soon after that quit taking the Tylenol. The first week in May I was able to ride horse for the first time since getting kicked, I quit wearing the TED stockings and pretty much resumed my normal schedule with no residual pain and no limp whatsoever. I still have a long way to go to build my stamina/endurance back up again as I was pretty much non-weight bearing on my right leg between getting kicked and the surgery but i couldn’t be happier with my progress and my results. I have a shoulder that needs attention also and I already warned Dr.Arntson that I will be making an appointment with him once horse riding season in MN is coming to an end this year.

Trust is the glue of life. Dr. Arntson’s had a distinct ability to calmly and professionally answer my questions about my anterior hip replacement, hospitalization and rehabilitation. This was my third attempt to find a surgeon that I trusted. This trust carried through the pre-surgery questions, my family’s post-surgery meeting and my follow up surgical appointments. I not only trust Dr. Arnston’s words, I trust his actions. I have had a much quicker rehabilitation than my former hip surgery. Such professionalism is an art. As such, Dr. Arntson is an artist I unqualifiedly endorse.

I have had a very good experience under Dr. Arntson and his team!
All aspects from preoperative to after surgery of my rotator cuff was wonderful
I had this surgery performed 30 years ago and extensive surgery which was much more painful recovery being non-arthroscopic
Every detail has been covered
My surgery went very well and recovery time has been much faster than I ever expected.
I just want to thank him and the team for such great job.

On November 14, 2014, in Wausau WI, I had a Total Left Knee Replacement, at the age of 63. On December 26, 2014, I was going down stairs to our lower level, and my left foot slipped on the 2nd to last stair, hit the floor hard, but I did not fall. I immediately had extreme pain in my left knee area. My doctor was on vacation and I was 5 weeks into my PT for my knee replacement. When PT examined my knee they were pretty sure I had torn my Quad Muscle , since I could no longer lift my leg. My surgeon confirmed, this and I had surgery on January 13, 2015 to repair my Quad. We moved to Elk River MN in July of 2015. Of course that meant finding all new doctors. We heard great things about Dr. Nathan Norquist and I met with him and knew right away, he was the doctor I was looking for. I was not feeling well at all. I had lost a lot of wait and my left knee/quad area was causing me pain. He referred me to Twin Cities Orthopedics and gave me names of two doctors that he felt could help me. One of those was Dr. Kruse. I met with him and I saw him a couple of times. He said he would like me to see another TCO doctor at another location. I saw this doctor a number of times and he thought it was my Quad Muscle that was not fully healed or strained. He put me back in a brace so I could rest it, and I was eventually released with the thought that the problem was the Quad Muscle. In December 2016, I went back to Dr. Kruse, and he asked me how my knee was doing, and I told him not good. He remembered that he had referred me to another doctor, so he asked his assistant to pull up all the records of what had been done. I told him I was so frustrated, because everyone was pointing to the Quad as the problem, but it was the knee that was causing the problem. My left knee was extremely warmer than my right, and any time I would walk or do really anything, my knee would turn red. Also, it felt like my knee was filled with Arthritis. As I would walk, it would just stiffen up more and more. It felt like I could feel the parts in my artificial knee bend with each step I took. Dr. Kruse, after examining me, told me I was right, and there was something wrong. The first thing he did was check to see if I had an infection in the knee. That came back negative. The next thing he wanted to check was to see if I was allergic to any of the metals in my knee. I told him that I would buy costume jewelry, and I had no problems with it. But, I did remember that way back in high school, my class ring did give me problems. Well the test came back saying I was Highly Reactive to Nickel and Mildly Reactive to Aluminum. I knew immediately that I wanted that knee taken out, and replaced with a new knee, minus the Nickel and Aluminum! Dr. Kruse referred me to Dr. Arntson for my total knee replacement / revision. I will never be able to thank Dr. Kruse enough, for taking the time and steps he did, in finding out what was really wrong with my knee replacement! I also want to thank him for referring me to Dr. Arntson. My total knee replacement / revision went so well. I walked out of the hospital and just used one crutch, when I went out of the house, for the first two weeks. After that I did not need it at all. I was released from PT at the end of 5 weeks and I could bend my knee to 138 and straighten in to 0. Thank you Dr. Arntson! I also feel so much better health wise. I had changes/symptoms to my body happen, after my first knee replacement, but I never related them to the knee. After, my revision they went away. Also, I wish I could have had the test to see, if I was allergic to any metals, before I had my first knee replacement. It would have saved me from years of pain and a knee revision after only 2 years and 3 months. Now, I am looking forward to enjoying the summer walking and riding my bike!

When I sought out a 3rd opinion on my left knee, I was scheduled with Dr. Arntson. My first appointment was very cordial and I remember leaving the office that day feeling very optimistic about my potential treatment. He ordered several tests, which is the first time a doctor has listened to me and not looked at me like my pain is all in my head. I’ve been in pain since 2012, had meniscus repaired, didn’t hold. Had partial, didn’t work for me.
Fast forward to after all the testing was complete, Dr. Arntson took the time to fully answer any and all questions about a total knee replacement, which he recommended. I started to feel very much at ease with my new Doctor – who then ruled out everything from the testing. So after the Holidays in 2016, I knew I had to make the appointment to get my surgery done.
Long story short; I had my total knee replacement revision on January 31st 2017 at Mercy Hospital, done by the amazing Dr. Arntson. From the morning I got to the hospital, to recovery, to my hospital stay, to home, I was well taken care of. And now 6 weeks out I am walking without pain!
Having my total knee replacement was the best thing I could have ever done for myself to get rid of the constant pain I was in. Dr. Arntson is literally an Angel. He has made my life better and I can now look forward to the rest of my life pain free!! I highly recommend Dr. Arntson and his staff.

I had a surgery with Dr. Arntson to repair a torn meniscus. Dr. Arntson was very informative with options, thorough with imaging and always took the time to listen and answer questions. Due to other medical reasons, I’ve had 12 surgeries over the past 8 years. This was my first surgery with Dr. Arntson. He was on time for the surgery, explained the procedure to myself and my husband and answered all our questions. He met with my husband after surgery, showed pictures of the procedure, explaining each one. I was extremely impressed when the bandages came off to barely see a trace of where the procedure took place. Recovery time was minimal. It was so refreshing to meet a doctor who truly put the patient first!

This is the 3rd total knee replacement revision in 10 years. The first two revisions were done by other physicians. Dr. Arntson performed the third revision and it is the best one yet. Dr. Arntson and his team were awesome. They seemed to care about me and this surgery more than any surgeries I had previously. I just want to thank Dr. Arntson for doing a great job and making me feel special.

Dr. Arntson performed a left anterior hip replacement on me. His professional pre surgery advice and recommendation left me with no questions. The surgery was completed with no complications. Dr. Arntson called me at home twice to check on my healing process. I am now pain free and live with no restrictions as the result of the surgery.

As an avid golfer and pickleball player, I was experiencing knee join pain and was unable to enjoy the two sports I love. I sought out an experienced (sports injuries) orthopedic doctor and located Dr. Arntson on the Twin Cities Orthopedics website and made an appointment with him. After examining my knee, he initially suggested an MRI however, his second option was the use of a Reaction Knee Brace. I’ve been wearing the brace now for three weeks particularly when I play Pickleball. The brace has provided good support for those times when I move quickly on the court. Thank you Dr. Arntson for your expertise with this issue. I would highly recommend him to anyone who plays sports and would like to continue playing without pain.

I am a 66 year old, very active woman. I was referred to your practice group by my chiropractor who had experienced fabulous results at the TCO Southdale clinic after breaking her leg.
Dr. Arntson seemed like a good fit and had a clinic location near me, so I came to see him about my knee pain. I had previously been seen by three MDs, one of whom specializes in sports medicine, and one who is an orthopedic surgeon. All three were quite dismissive about my pain, and all told me that “it’s just arthritis, everyone gets it.” When asked what I could do, none of them offered any solution other than leg exercises, which hurt so much that I couldn’t do them.
Dr. Arntson gave me his undivided attention and it was clear that he took me very seriously. We discussed the different alternatives available (cortisone injections, gel injections and knee replacement) at length, and I fully understood the options. I opted to go with cortisone injections. He was very helpful in making sure that my insurance would cover the visits and the procedures, and I received the first injection in my right knee.
It seems to make an immediate difference, so I came back one week later for the injection in my left knee. His bedside manner, gentleness in prepping and injecting my knees was remarkable. I had absolutely no pain either time.
Unfortunately, the relief only lasted about 6 weeks, so I returned, and we decided to try the injections of gel. These have been very helpful, again, no pain upon injections, and increased flexibility and comfort in walking.
I know that Dr. Arntson believes that I will let him know if I need further treatment, and if so, we can assess my progress and discuss my options. I would happily recommend him and the entire staff at the clinic to anyone.

Dr. Arntson and staff have been Fantastic, the nursing staff ( Fridley, CR, Otsego) have been so kind and comforting through this tough surgery and recovery process, including the X-ray & MRI techs. Kristin, Dr. Arntson assistant has been so kind and helpful making sure I don’t miss any appts. I would highly recommend Dr. Arntson to anyone for ACL surgery he is very transparent and truly cares about his patients.
