Hello, my name is Floyd, and a patient of Dr. Sumko. I’ve had two total knee arthroplasty surgeries. Both of which have been a wonderful success. I am pleased to say that, I’ve just received my release to return to work and have no problems or concerns regarding my ability to perform my duties. In 2017, I had the two surgeries done the first on 6-7-17 and the other on 12-20-17. Anyone who is considering knee surgery, under Dr. Sumko’s care and professionalism, you can be assured that in the state of Arizona you’ll be in the best care possible. Dr. Sumko is respectful, humble, and above all, a true professional in his field. I cannot emphasize how grateful and satisfied I am with the outcome of both surgeries. I am back to walking my dogs again, about three miles a day and haven’t any issues with my knees. Thank you, Dr. Sumko.

On Nov 27.2017 Dr. Sumko performed a total left knee replacement. That day I was up and walking. The next day I went home. I never needed anything stronger than Tylenol for pain. This is the second
knee I have done, the first was 14 years ago. Remembering that discomfort kept me from doing my left until I couldn’t put it off any longer. Dr. Sumko did an amazing job, if you need knee work do not put it off go see Dr. Sumko today.

I am the niece of Ellen who is 88 years young. 8 weeks ago Dr. Sumko did surgery for a Rt knee replacement for Ellen. From the first consultation to the last clinic appointment Dr. Sumko exceeded our expectations. His bedside manner shines and Ellen is now walking pain free. His office assistant Lisha is top notch! Every professional who assisted us throughout her procedure, including the physical therapist who worked with Ellen afterwards, had great things to say about how well Dr Sumko’s patients recovered after surgery. I give Dr Sumko and his office assistant Lisha an A+!

My hip feels terrific! Six weeks ago I had my right hip replaced by Dr. Sumko. In three days I was walking so well that I have not used a cane or walker since. I found a surgeon I could trust in Dr. Sumko and have no regrets that it took me eight years to find him as the results have been spectacular. Dr. Sumko is one of the best surgeons doing one of the most current hip replacement procedures. He has a great assistant Lisha who is always responsive to any questions or concerns that I have. The procedure took place at Tempe St. Luke’s Hospital, and the staff that provided the preoperative and post operative care, were conscientious and reliable. I received the best care possible. It is now seven weeks after the operation and I am swimming (the operation site is securely healed) and riding my bike. No pain, fast healing and my leg is, for the first time in eight years, normal. I am so impressed with the results! Thank you Dr. Sumko!

After suffering with bilateral knee for over six months, having cortisone and gel injections with no relief, it became obvious that surgery was the only alternative left. I searched for an orthopaedic surgeon. I was led to Dr. Michael Sumko by patient testimonials from physical therapy. I found him to be very friendly, knowledgeable and open to answering any questions I had. I never felt rushed or that he didn’t care. The day of my knee replacement surgery he asked if I had any questions and explained the procedure again. He saw me after surgery to let me know how the surgery went and what to expect. I’m exceptionally happy with the results and I’m having my other knee repaired in a few weeks. I WOULD DEFINITELY RECOMMEND DR. SUMKO TO ANYONE thinking of knee or hip surgery. THANK YOU DR SUMKO!

Ever since December 2014 I had a rapid onset of difficulty standing. This progressed until I started to use a cane. I saw a doctor who referred me to a back surgeon and had surgery on my back in June 2015 in the Dallas, TX metro area. From then on I never recovered my ability to walk properly. We moved to Surprise, AZ in April 2016. All this time I was getting worse, and the pain was worse than ever. Again, I saw a doctor who referred me to Dr. Michael Sumko at [Steward Orthopedic & Sports Medicine Center] after x-rays were taken. Since that time meeting with Dr. Sumko, and him doing Rt. Hip Arthroplasty, my pain on that side is non-existent. And I am anticipating with great expectancy the left hip to be done by Dr. Sumko also. He has literally given me my life back. The mobility is returning, and I know it’s just a matter of time before I will “skip” down that office hall to report to him. After two years of being in pain, and not able to walk or do what I need to do, Dr. Sumko has restored that ability for me. I am eternally grateful, and have recommended him to some folks in need just as I was. May God bless [Steward Orthopedic & Sports Medicine Center], and Dr. Sumko richly. He is a shining star and a good person to know. Your light will shine bright for a long, long time.

After he reviewed the x-ray of my hip, Dr. MIchael Sumko told me that I needed a total hip arthroplasty and that I had waited much too long. My right hip had been bothering me for about 6 years, and I had seen a couple of Orthopedic Surgeons in Australia about 2 to 2.5 years ago. They said that I had end-stage arthritis in my knee and hip, but replacing them was a “quality of life” decision. The pain had been manageable while the hip deteriorated slowly for the past 5 years. This past year the deterioration of the hip and the associated pain exacerbated. Dr. Sumko told me that after the surgery that I would walk. I thought that sure, I will walk in spite of the pain from the incision. Well after having the surgery October 5, 2016, and awakening from the anesthesia, I walked and for the first time in 6 years, I walked pain-free. The pain associated with the incision was about 10% of the pain I have endured much of the past 6 years! Bravo Dr Sumko and the direct superior approach to hip replacement!

I was on short term disability and being seen by another Pain Management doctor. Three epidurals later I was still in pain. I realized during this time of my life that some doctors are not the perfect fit. Decided to change doctors and went to Dr. Walter Damper and what a miracle he has been to me. My very first visit he examined my spine and realized why my pain was radiating in my hip and knee which I had explained to my previous doctor. Dr. Damper on my first visit gave me an injection in my knee and hip which relieved some of my pain. The next few weeks he did a sacroiliac joint injection in my low back which started to relieve more of my pain. Within a few weeks of these SI injections, I was back to work and feeling great and able to take my walks again. I highly recommend Dr. Walter Damper. I feel like he came into my life at the right time to help me get out of the tremendous pain I was in. To me, his bedside manner is wonderful and a true blessing as a doctor.

Back in 1980 I suffered a broken knee while working in a South American country. My knee was reconstructed using the technology that was available at the time in a third world country. As expected, the procedure did not go well. Over the decades I experienced increasing pain from arthritis. The pain got to the point that it became intolerable. Then on April 4th, 2016 I took the plunge and had Dr. MIchael Sumko perform a total knee replacement. I was impressed with the modern technology. I only spent one day in the hospital and was walking around a few hours after the surgery. Four days later I started rehab. After six weeks I obtained considerable mobility and now have a totally functional knee. I am very pleased with the outcome and impressed by Dr. Sumko’s bed side manners and his surgical skills. I will not hesitate to recommend him to anyone who needs a total knee replacement.

After over a year of having trouble walking I saw Dr. MIchael Sumko. He replaced my right knee and I was good to go after 6 weeks! I can’t tell you what a change this has made in my life. I will be getting the other knee done so I can enjoy the lifestyle of hiking, biking, and the gym! I can’t praise Dr. Sumko enough for his bedside manner and skill as a surgeon.

For the past year my mobility has gradually diminished to the point that I was unable to walk without assistance and then not able to walk at all. Suffering with excruciating pain, I met with Dr. Michael Sumko of [Steward Orthopedic & Sports Medicine Center]. After the initial consultation, I left knowing I was in good hands. Dr. Sumko was attentive and listened to my concerns. He was thorough in evaluating my situation. I was not your typical text book case for a hip replacement. Everything about my hip was a disaster!! I was bone on bone with bone fragments visible in the x-ray. My bones were worn down and miss-shaped. Dr. Sumko and I both knew this surgery would be difficult but agreed it needed to be done. Two days prior to my surgery I was admitted to the hospital. During this time Dr. Sumko listened to, and responded to the concerns my family had for my welfare. This has been a humbling experience for me. Not only am I grateful for Dr. Sumko’s skills as a surgeon, but for his ability to see and understand what needed to be done in difficult circumstances such as mine. He was confident, yet cautious in addressing my specific needs and as a result I couldn’t be more pleased with the outcome of my surgery. It’s great to be walking pain free!

Thank you to Dr. Tim Bert and [Steward Orthopedic & Sports Medicine Center] for making the process of Hip Arthroscopy a (relatively) painless one! I am extremely happy with the level of care I have received from Dr. Bert, his MA Jennifer, and the additional office staff. He is extremely knowledgeable on hip labrum tears and FAI impingement, and incredibly skilled in this rather new corrective procedure. This surgery is technically difficult, and you NEED to have the best trained and skilled surgeon! I suffered for two years with hip pain and instability after the birth of my daughter, and after several rounds of PT, I decided to see if there was a structural reason for my pain. I was referred to Dr. Bert from my Physical Medicine physician, and I’m so happy he was my surgeon. He is up on the latest research with this technique, and his guidance has helped me to recover quickly from this surgery! His MA Jennifer answered all of my questions before and after surgery in an extremely efficient manner, which helped ease my mind as I was approaching surgery and in the days after. I am also very happy with the level of care I was given at St. Luke’s Medical Center’s surgical Orthopaedic unit, they are great! If you have a hip labrum tear and/or FAI impingement, Dr. Bert at [Steward Orthopedic & Sports Medicine Center] should be your first consult. I highly recommend him without reservation!
