Linda J.

I can hardly believe that it’s now been over 3 years since Dr. Mark Fischer did my successful Carpal Tunnel Surgery. EMG results and clinical tests had confirmed my bilateral struggle was worthy of getting them both fixed, so I did both hands one month apart (but with 2 different surgeons). After knowing my 1st surgery’s struggle, I was so grateful that he didn’t put me under anesthesia for the surgery. I enjoyed being awake during the surgery with just the operable area isolated for surgery. I got to ask questions of him and the team and watch the screen during the surgery. Yes, some of us geeks love that stuff. I only regret that I hadn’t first met Dr. Fischer so both hands could have been successes.

I was suffering for quite a while from bursitis and thumb arthritis. I called Twin Cities Orthopedics who connected me with Dr. Fischer. He was wonderful. In a matter of minutes Dr. Fischer knew exactly what my problems were and how to fix them. I had heard horror stories for years about how painful cortisone shots were. That was not the case with Dr. Fischer. I was pain free within a day. He works miracles and I am so glad I found him. He specializes in hand and wrist areas but was kind enough to help me with both of my shoulders. What a wonderful and caring doctor.

Dr. Fischer was wonderful. He diagnosed my problems immediately and within a day, because of his expertise, I starting getting relief.

Falling and fracturing a finger was traumatic for me but being able to be seen immediately was a relief. The surgery was a success, occupational therapy was a success, and the end result was what I expected. My experience from check in, to the nurse, x-ray tech, patient care coordinator and surgeon was wonderful! Much time was spent during my appointments and I never felt rushed. I recommend TCO and Dr. Mark Fischer. Thank you!

My wife and I both suffered from severe arthritis in our thumbs. We both followed Dr. Fischer’s non-surgical treatment plan, and ultimately took his advice to have the related surgery. With each of us having the surgery on both of our thumbs, we carefully timed them to give each hand recovery time between surgeries. Between the two of us, we have always had one functional hand! Today we both have the function of our thumbs back, without the arthritic pain that had severely limited our daily activities. Long story short, and four thumbs later, we are both grateful to Dr. Fischer for his surgical skills to give us back the function of our hands, and his excellent staff that took care of all the administrative, physical therapy and nursing details.

I just wanted to send a thank you to Twin Cities Orthopedics for the excellent care I have received. From my first contact with TCO to Dr. Fischer‘s surgery, I have felt well taken care of on my road to recovery. The week of my fall is a blear, so I am grateful to you all for your help. Dr. Fischer’s surgery was excellent and I am confident that I will be functioning at a normal level soon.

I want to take this opportunity to thank Dr. Fischer. I feel blessed to have had the thumb CMC arthroplasty I so needed. I have been suffering with severe arthritis for the last 10 years and no medication ever helped the pain. The surgery and tissue transplant has allowed me to feel great. No pain in that area and I have better range of motion with higher functioning.

Dr. Mark Fischer saw me quickly and scheduled surgery in 2 days. I had a horribly fractured wrist that needed 2 plates and 10 screws to repair. He was a wonderful technician with great bedside manner. I healed with no infection or complications. Therapy has helped get me close to normal. It has been 7 weeks. I would recommend him highly.

I’ve had three hand surgeries with Dr. Fischer. He is THE hand guy in MN. Transplants in both thumbs due to arthritis and trigger finger surgery in two fingers. This man is talented. The arthritis in my thumbs hurt so bad I couldn’t sleep. So, I decided to have the transplant surgery. Recovery took about a month. Eight years later, my thumbs are still perfect…no pain…I can do everything I want to do again. If you need this type of surgery, don’t be afraid. Recovery is quick and results are perfect. Dr. Fischer is the right guy to do this.

Dr. Fischer has been my doctor for the last eight years. When I first came to him my right hand and arm were crushed and badly burned by CO2. Dr. Fischer is a very thorough doctor. I now have full function of my hand. While it may not be the strongest, I still have my hand. Thank you Dr. Fischer for doing your best so I have the use of my right hand and arm.

I came in with a cut hand that needed surgery. I was rather scared. Your front end staff was excellent. They helped me with all my needs! Dr. Fischer was great, he explained the procedure to me, and was very kind. I also worked with Amy, and she was very helpful, and very friendly.
I have been back to have therapy, and your therapists have been wonderful. I have been working with Rochelle.
Your clinic is a busy clinic, but I have never felt rushed.
Thanks to all the staff for excellent customer service.

My hands had been bothering me for quite some time and would even fall asleep while I was sleeping. After I realized that the pain wasn’t going to get any better, I decided to make an appointment with my doctor who then referred me on to Dr. Fischer with Twin Cities Orthopedics.

From the first appointment with Dr. Fischer I felt very comfortable. After taking one look at my hands, he knew exactly what I had been suffering from and decided that it would be in my best interest to move forward with a surgical approach.

Everyone we came into contact with at Twin Cities Orthopedics was extremely friendly. From the front desk reception staff to the surgical staff, they always made me feel comfortable and relaxed. My procedure went very smoothly and Dr. Fischer made sure to check on me to after I left the operating room. I could not believe how attentive the staff was!

My recovery has been stress-free and I am following along with the recommended exercises at home. A month after my surgery and I am almost completely pain free!

My first meeting with Dr. Fischer was quick, professional, and down to the point. The fact that he has done so many procedures was important to me, and that he used a very small incision was a plus. The whole team for surgery was very proficient, explained what they were doing and what to expect. This goes a long way for most people. In my case there was little or no discomfort, more of an inconvenience than anything.

The feeling in my hand steadily improves each week, and is close to being normal again. I would personally recommend Dr. Fischer.

Thank you, Dr. Fischer, for a job well done.
