Dr. Dieterle replaced my left shoulder and the caliber of his workmanship and skill level is incomprehensible! Within 3 days post-surgery I was using my left arm for pretty much everything that I needed to. My pain level was next to nothing, and within 3 weeks I was able to do anything that I wanted to. By the 7th week, I could say it’s as if I never had it replaced. It is performing as well as my shoulder did when I was young. This is attributed to his skill level. In my opinion, Dr. Dieterle is a marvelous surgeon.

Ever since I was young, my passions have been playing basketball and volleyball. During my eighth grade season of basketball, I tore my ACL and meniscus in my right knee. I’ve never had a serious injury before so the orthopedic field was new to me.

My mom took me directly to TCO to get specialized care. This is where I met with Dr. Jason Dieterle. It was an amazing first experience. Dr. Dieterle gave me valuable input and made me feel cared for as a young, injured athlete. At the time, I was extremely scared and nervous about the road ahead, but I knew I had a great team to support me.

After spending months recovering, I was blessed with a healthy nine months of playing sports. During my sophomore volleyball season, I tore the ACL in my opposite knee. I immediately made an appointment with my favorite person at TCO, Dr. Dieterle. He performed my ACL reconstruction surgery and did amazing work!

Although I am not sure about y future sports career, I know that whenever I choose to play I will be extremely strong! Both surgeries and recoveries made me who I am today. The group of physicians and staff at TCO will make sure you get back to doing what you love in no time!

As I contemplated the prospect of a total knee replacement, I knew that I had to place my trust in the skillset of the surgeon. As patients we basically surrender to the process and hope for the best possible outcome. I decided on the surgery because my knee pain after exertion was limiting my ability to do the things I loved. My experience with Dr. Dieterle has proven to be transformational. I am 9 weeks post-surgery and my new knee is functioning at a high level. I am walking and biking for 1-2 hours is back in my routine. Now instead of my knee getting worse every day I feel it’s getting better each and every day. Dr. Dieterle is an expert. Do not hesitate to put your trust in him!

Thanks to Dr. Jason Dieterle and TCO’s EXCEL Program, I’m feeling great after a total knee replacement. In fact, just 3 months after surgery, I had more mobility in my knee than I’ve had in the past 15 years. Dr. Dieterle was very professional, honest, and straightforward. As a toolmaker for over 30 years, I’m someone who appreciates quality work, and Dr. Dieterle went the extra mile to make sure I had a great experience. Just recently, I returned from a bucket list fly fishing trip to Canada that I couldn’t have done without this new knee. I already have my next trip scheduled!

Sharon S.

I can’t believe how great this surgery performed by Dr. Dieterle was! If I need my other shoulder replaced, I would do it in a heartbeat. My shoulder is as good as new! After surgery I had NO pain either!

April 6, 2022

Sonia H.

The improvement was felt very quickly. Soon after my knee surgery with Dr. Dieterle I could walk without pain. It was the first I could walk without pain in years!

April 4, 2022

Deborah K.

I had an excellent experience with my full knee replacement performed by Dr. Dieterle. From the original diagnosis, surgery 3 months later, and after 6 months, I am very satisfied with my recovery to date. The physical therapy staff and receptionist staff were great as well!

March 28, 2022

Staci B.

Dr. Dieterle and the entire staff kept me informed and made me feel normal with everything I was experiencing. They reassured me that what I was feeling was part of the process. Everyone has been supportive, informative, and so great to work with. I hope that I don’t have to ever see them again, but if I do, I will come back to TCO!

Lynda O.

Before surgery the pain was constant and I couldn’t do many normal things. The surgery was instant relief thanks to Dr. Dieterle. I am able to do my housework and many other activities including golf!

February 26, 2022

Scott P.

My surgery with Dr. Dieterle was to reattach my rotator cuff and bicep tendons. The surgery went well, completely restoring my strength and range of motion, eliminating the pain! Post-op sleeping up right was a little difficult, but a cushy recliner made a huge difference. The physical therapy was critical in my recovery. Do your PT!

February 20, 2022

Mark M.

My shoulder surgery went very well! If it wasn’t for Dr. Dieterle and the staff at TCO, I might not have been able to repair my injury.

Elli L.

Communication with my healthcare providers is key. With that said, I did initiate conversation with my surgeon, Dr. Dieterle, who is a wonderful listener and highly skilled doctor specializing in shoulder issues. I had trust in him as I learned about his history of performing successful rotator cuff procedures. He did not hurry me in asking my questions, nor dismiss me in any way of my concerns. Secondly, the anesthesiologist called me as I requested, I had airway issues in past surgeries, so I could discuss concerns for any potential breathing problems. He was so considerate and thanked me for the heads up. From time I walked into Lakeview Hospital, I was greeted courteously and respectfully. The nurse’s assistants and other providers made my experience well tolerated and the careful manner in which my extremity was handled allowed me to feel very little pain and recover with significantly less pain than anticipated. Thank you, I would utilize this same system of providers if needed!

Grace G.

After my shoulder surgery with Dr. Dieterle, the pain is gone that was present for a long time. Physical therapy is crucial to recovery in range of motion and strength. It restored my ability to resume my daily routine.

December 15, 2021

Robert S.

I’m very happy with the results of my shoulder surgery performed by Dr. Dieterle. I was able to play a total of 63 holes of golf before my 2 month anniversary of surgery!

Margaret H.

My shoulder replacement surgery with Dr. Dieterle went extremely well. Physical therapy post surgery went great too. I continued my exercises after I was released from therapy and now have extremely good range in my shoulder. This surgery was a godsend for me as I was in constant pain before I had it. What a miracle!

Pauline A.

Left shoulder replacement surgery was a total success! I should have had it done sooner because it was extremely successful and took all my pain away, almost immediately! Dr. Dieterle and all staff, including the Lakeview Hospital in Stillwater, were more than competent and always answered my questions (and I had a lot). I know I’ll need my right shoulder done eventually and will ask Dr. Dieterle to do my surgery.

August 3, 2021

Mary S.

My shoulder replacement with Dr. Dieterle was the best thing that happened. After excellent physical therapy, I felt great! Don’t wait until the pain is intolerable, you’ll be wishing you had the replacement surgery sooner rather than later!

July 2, 2021

Robert H.

Dr. Dieterle did an excellent job replacing my right shoulder. It was the first time in my lifetime that I did not experience post-op pain (after 12 surgeries by other surgeons). My recovery has been painless and fast. After hearing about many experiences of others who had shoulder surgeries, I still cannot believe how painless and easy my surgery and recovery was. I am scheduled to have Dr. Dieterle replace my left shoulder in September. I heard from other patients, as well as doctors, how great Dr. Dieterle is and I can now add my endorsement testimonial with great appreciation for what he did for me. Thank you Dr. Dieterle.

June 6, 2021

Wanda K.

Having my knee pain and going through the steps I needed to do to get my knee replaced was worth it. Just do your therapy and keep moving forward. Dr. Dieterle and the whole medical team were great. My husband has a new knee too and is doing great. Thank You TCO!

Brendan I.

I’m glad I went through with the surgery with Dr. Dieterle. I put it off too long but now I have confidence in my knee again. I am in the best shape of my life now and am regularly running and biking farther than I was before.

Patricia F.

I had my right shoulder done in 2019 and my left done in 2020. My surgeries went very well. Recovery with physical therapy was intense but very successful. For 20 years I struggled with not being able to dress properly, reach above my head, lift grocery bags, golf, and many other things needed in daily life. No one offered help until I saw Dr. Dieterle and he suggested a reverse total shoulder surgery because both rotator cuffs were not good. I am very pleased with the outcome and that I am able to do most everything like normal. If anyone needs to have this procedure done do not wait years, it’s not worth the misery of pain and inconveniences.

Jeffrey S.

Dr. Jason Dieterle and his team at Twin Cities Orthopedics have been fantastic. I have had two rotator cuff surgeries in the last six months and I had little to no pain with either surgery. Everyone has been great to work with!

April 22, 2021

Donald A.

I had injured my shoulder bad enough that I almost couldn’t use my arm. The surgery went very well! I have been healing and regaining strength in my shoulder as I continue my exercises every day. Life is good thanks to Dr. Dieterle and the modern technology used in the surgery I had.

March 28, 2021

Bruce R.

My shoulder surgery was a complete success thanks to Dr. Dieterle.

Nolan H.

Surgery with Dr. Dieterle was the best decision I’ve made and am now pain-free and fully recovered! There was no loss of mobility and I have resumed all normal activities. What more could you ask for?

February 26, 2021

Susan C.

I would definitely recommend knee replacement for those who need it. Now I can do almost everything I need. I can’t imagine what life would be like without my replacement surgery performed by Dr. Dieterle!

February 12, 2021

Eric L.

The surgery went much better than I anticipated. The pain actually went away a couple of days after surgery. Dr. Dieterle and the entire team were very professional and caring.

February 11, 2021

Jay K.

Dr. Dieterle is a very skilled surgeon! I have and will continue to refer others to him.

January 26, 2021

Steven U.

The result of the shoulder surgery performed by Dr. Dieterle gave me full, pain free movement. The recovery and therapy take time, but the result is worth the effort. My physical therapist was excellent in providing support, informing me on what to expect and the time required for recovery.

January 18, 2021

Christopher G.

I was recommended to Dr. Dieterle by another orthopedic surgeon that said “If I’m having my shoulder done, Dr. Dieterle is doing it.” That’s all I needed to hear, I made the appointment the same day and couldn’t be happier! My left shoulder injury included torn rotator, labrum tear, bone spurs, arthritis and issues with the bicep tendon. Dr. Dieterle knocked it out of the park! Before and after surgery I worked with physical therapist extraordinaire, Brett Peterson. What a remarkable team these guys make!! There is both pre- and post-surgery therapy to be done. DO YOUR THERAPY! TCO has the best support system that I have encountered to help me reach my goals. Not a chance that I would go anywhere else for surgery or rehab! Thanks TCO!

January 6, 2021

Jon S.

I’m very happy with the shoulder surgery and physical therapy. It exceeded my expectations. Dr. Dieterle is amazing!

October 7, 2020

Dr. Dieterle and staff (Scott) in PT were excellent! They did what they promised and cared for all concerns. TCO is the best! Thanks again for the great care and professionalism. Good job guys!

Surgery with Dr. Dieterle got me back to 100% normal life and activity and PT was very beneficial.

July 2, 2020

Donald H.

Prior to surgery, I was bone on bone with both knees and in very much pain, relying on a cane to walk. After surgery with Dr. Dieterle, I’m now able to resume activities at a near normal level and feeling good again.

July 1, 2020

Howard K.

Prior to surgery, the right shoulder pain was excruciating and use of the arm was limited at best. I could not lift the arm past elbow height. After surgery, the pain was immediately relieved. After a month of rehab, pain was gone and movement of the shoulder and right arm was nearly normal again. I had pain-free movement that I hadn’t had in years. After nearly a year, the surgery is nearly forgotten and life and activities have increased. Thank you Dr. Dieterle for helping me to get back to being pain free.

May 10, 2020

Jaime O.

Dr. Dieterle set realistic expectations and exceeded them all. I had very little pain during this process and on a much faster recovery cycle than expected. The PT team is outstanding, and the results achieved to date could not have been achieved without the surgery and PT team’s well coordinated efforts.

May 8, 2020

Greg M.

Before surgery with Dr. Dieterle, my pain was terrible and I couldn’t do much of anything. After 2 knee replacements, my life is back to normal and pain is at a minimum.

May 5, 2020

Maurice P.

I am definitely glad I had my rotator cuff repair done with Dr. Dieterle.

March 13, 2020

Cheryl L.

Following my total knee replacement with Dr. Dieterle, there is no more pain! I can even get down on my knee! It is so, well, I can’t explain how wonderful that is. Now I need a hip and other knee done and am really looking forward to it!

March 7, 2020

Maryanne R.

I had a total knee replacement done with Dr. Dieterle and now I can walk with no pain and it feels amazing!

January 14, 2020

Howard K.

After not being able to perform even simple tasks with my right arm, physical therapy did not help. The reverse shoulder replacement was performed by Dr. Dieterle and the pain relief was immediate. Function of the shoulder was better with therapy. After 6 months post surgery, I have movement I have not had in 5 years and it improves daily. I can move and perform tasks over my head that I could not do previously. Shoulder does fatigue after a long day but it improves daily.

Jeanine K.

The pain I was having limited so many things in my daily routine, it change the LIFE I was living. Now, after a total knee replacement with Dr. Dieterle, things seem so normal.

December 31, 2019

Jean S.

After my total knee replacement performed by Dr. Dieterle, I am able to walk down hill with no pain and can walk much faster, leading to more activity and taking more walks.

Carole S.

Recovered quickly after surgery with Dr. Dieterle. Little pain. Resumed normal activities within a couple weeks. Zip lined at 6 weeks and sky dived within a couple of months. Great outcome.

Caroline B.

It happened so fast! Wham, I fell forward hitting my right shoulder on the pavement/curb. ER trip indicated multiple bone fractures on my upper right humerus. My call to TCO was “I want the best shoulder doctor available”. Enter Dr. Jason Dieterle and his fabulous team. Surgery was scheduled 4 days out at Lakeview Hospital. The surprise was that it was actually shattered and the doc had to remove fragments of bone before inserting a plate held together with pins. Seven months later, a pin pulled out of the bone and scans indicated that the bone would not mend. A second surgery was scheduled to remove plate and pins which were replaced by reverse shoulder equipment. Through all the pain and rehabilitation and dealing with my disappointment about an added surgery, Dr. Dieterle and his team consoled and encouraged me. I am so grateful. I got the best shoulder doctor plus his fantastic team.

Cecilia W.

I have pain free range of motion and will continue to regain all ROM and strength. I had this shoulder replaced far earlier than I had done the right shoulder and saved myself from further pain, discomfort, and decreased ability to use the shoulder.

I’m very verbal about my surgery and hopefully am empowering others who have joint pain (of any joint) to consider replacement. If it’s a shoulder, I always recommend Dr. Dieterle.

October 21, 2019

George K.

I had a total knee replacement with Dr. Dieterle and the only thing I can said is that I should have done it sooner, years sooner.

October 9, 2019

Jackie H.

I had a bad result from a previous surgery with another orthopedic practice. My shoulder was painful most of the time. I had a re-tear and nerve issues along with frozen shoulder. I was expecting about a 50% improvement after Dr. Dieterle did the surgery and Lisa Richardson the therapy. My arm is about 95%+ better! I am very happy and relieved and I even surprised the doctor. He said he was amazed and surprised I got back the rotation and movement with very little pain. Both did a fantastic job cleaning up the mess I was left with after previous surgery. I tell everyone how great they are!

September 3, 2019

Betty O.

Everyone is amazed at how well the reverse total shoulder replacement surgery went. Dr. Dieterle has done an amazing job and I would strongly encourage anyone that needs the surgery to do so.

August 17, 2019

Arthur F.

I had a reverse total shoulder replacement performed by Dr. Dieterle. Now, my right arm feels better and I can use the right arm more often for daily activities.

My rotator cuff repair with Dr. Dieterle has given me a much more positive outlook on life.

Dear Dr. Dieterle,

I wanted to take the time to personally thank you for seeing me on July 6th for severe shoulder pain. You were very respectful and caring as you reviewed my shoulder range of motion. How fortunate I was to be able to see you so quickly. Your expertise was evident and your willingness to try and further educate me on the issue at hand as well as future care was most appreciated. The cortisone shot relieved much of the extremely excruciating pain within 6 hours. It allowed me to use my hand; forearm and some shoulder motion and of course receive some much-needed rest. It provided me with the ability to once again type with this specific note to you. Your entire staff at the urgent care center was very helpful and understood my anxiety from the pain and lack of sleep. Please compliment them for me. Note that what may have been a routine review of a patient was most appreciated.

Your most helpful service was valued and your organization should know of your talent and skill with patients. Thank you again.

Fell off my mountain bike and busted my collar bone into 4 pieces. Although it would have healed on it’s own, there was a chance that it would do so incorrectly. Dr. Dieterle put me back together (anatomically correct!) and I’m pleased. I’ve had colds last longer.
