For 5 years, I have known I needed both of my hips replaced. I put off the surgery and dealt with the pain until it started to affect my back. I knew I had to do something and finally, I had an in-depth conversation about the surgery with Dr. Lewis. I had high anxiety, not about the surgery or recovery, but due to waiting and thinking about the process. Dr. Lewis reassured me about the process. I finally agreed to have my right hip surgery done at the Minnesota Valley Surgery Center. As soon as I checked in, I was put at ease. The first nurse I talked to (without being prompted) acknowledged my anxiety and said it would be addressed. A short time later, I met with the Anesthesiologist. He too, without being prompted, said he knew of my anxiety and would take care of me. I was given some pills and was very comfortable leading up to my arrival at the operating room. I don’t remember a lot about the surgery itself but the rest of my stay at the Surgery Center was very comfortable.

They were a great and caring nursing staff. The entire visit, from the home nurse to the physical therapist, went smoothly. My follow up visit with Libby Witchger and Dr. Lewis went well and truly, the entire process went so well. I am considering have my other hip done as soon as I can. My biggest concern was the pre-surgery anxiety but because of the caring and concerned staff, it was barely noticeable.

Dr. Lewis replaced both of my knees, one year apart from each other, and he and his staff are rock stars. He also did my wife’s knee replacement. I also want to say that his assistant,Libby, is the best. I would definitely recommend him and Libby for your orthopedic needs. I developed scar tissue in both knees and Dr. Lewis said a small number of patients get this and that it’s common. They both made noise and hurt when getting up from a sitting position. It was about a 20 minute procedure and they are perfect. Many thanks Dr. Lewis and Libby. You guys are great.

I can’t say enough good things about Dr. Lewis and his team. He did two total knee replacements for me, three months apart. Everything went exceedingly well from the first appointment to the final appointment. I experienced good communication, along with friendly and helpful staff. My recovery with PT was fast and successful. At all times during the process, the staff was friendly & helpful. Dr. Lewis is friendly, funny, & kind. He is also amazingly prompt in updating health records so you know what is going on. I recommend Dr. Lewis, without reservations, to anyone needing knee surgery.

I am passionate about teaching therapeutic horseback riding and showing my horses. During the 2019 show season, I had to have help getting on my horse because of the terrible hip pain. My performance was suffering and so was I. Dr Lewis replaced my left hip in January 2020. I couldn’t believe the relief! I was riding again by spring and showed all summer, even though my right hip was still a problem. In October, Dr. Lewis replaced my right hip. I have a matched set now. The recovery from the right hip was even easier and I was back to riding 6 weeks later. I can hardly wait for show season to start in the spring!

Dr. Lewis and his staff were wonderful. I felt like they were as vested in my recovery as I was. Every detail of this surgery went smoothly. All my questions were answered clearly and I was completely at ease with the process. These people are in a class by themselves!

I’m so lucky Dr. Lewis was on duty when I fell ice skating and fractured my right femur. He is kind and caring and has a lot of expertise. My leg has three big pins, but feels normal with no more pain. I was a lucky person.

Dr. Lewis was wonderful in the replacing and recovery on my knee. Very compassionate and always took time to listen to my concerns. I will highly recommend him to my family and friends.

Thank you, Dr. Lewis and Libby, for the excellent care! In the past year, I have had both knees replaced with great success. I am now 10 weeks post-op of the second replacement and I am already doing things physically that I haven’t been able to do in over 10 years. Dr. Lewis is kind, caring, honest, knowledgeable and competent. I greatly appreciated that he and Libby always took the time to answer my questions and provide me with options for my care. Dr. Lewis didn’t try to “persuade” me to have surgery but initially used more conservative practices to treat my knee issues. When the time came for me to proceed with replacement surgery, there was no doubt in my mind who I would trust to do the surgery. I can’t thank Dr. Lewis and Libby enough for providing such great care.

I needed a knee replacement since November of 2016. I was reluctant to do the surgery but I finally had the surgery on July 15th, 2019. The results are amazing! I could put weight on the knee immediately with no pain. I used a walker for a week and then used a cane for another week or two as needed. After three weeks I could do almost everything. PT and home exercise really helped me heal. I want to thank Dr. Lewis and his staff for the great care!

Thanks to Dr. Lewis I am a new man! I had been suffering for quite some time. My right hip had deteriorated to the point where it was bone on bone. My quality of life was at an all-time low. I went to TCO and met with Dr. Lewis. He immediately had a plan to help me, and I was able to schedule a hip replacement surgery in no time. The surgery was a complete success, and I was home within a few days. No long recovery time. I was back to my ol’ self. I felt fantastic! No more pain! I could go back to everyday living and be able to do the things I loved but couldn’t because of my hip. Thanks to Dr. Lewis and his team at TCO! I can’t find the words to tell you how much I appreciate what you have done for me.

Ann R.

Hello! My name is Ann and I’ve been a nurse for 40 years now, started when I was 6! I manage the MN Veterans Home Adult Day Center, where a group of “angels” care for our nations Veterans who mostly suffer from Alzheimer’s disease. We call it, “the Vet’s Club”. I got up at 4am on the morning of December 7th, 2018 (D-Day) – should have known, and was so excited because we were having a holiday party for our Veterans and their families, and all the staff dress up silly. Well, coffee cup in hand and still half asleep, I tripped over a boot in the hallway at home, and went airborne landing on my left shoulder. All I saw were stars and felt pain like I’ve never felt before, made labor pains feel like a walk in the park. I crawled to my phone, called for help, and ended up at Fairview Ridges ER. Long story short, shattered neck of my humerus (not humorous to me!) and was sent to Burnsville TCO to see Dr. Lewis, who felt I had fallen the correct way and could possibly heal without surgery – I fell the right way! Yaay! Was he kidding? I could hardly move and about wanted to die from the pain. It’s funny how you take simple, everyday things for granted, like fixing your hair or brushing your teeth, until you can’t do them by yourself and have to rely on others – nurse’s are not good at asking for help! I, of course went back to work after 9 days, way before Doc Lewis said I could (don’t tell him!). Nurse’s make really bad patients! When Doc Lewis gave the okay, I was put into the wonderful hands of a physical therapist, Alex Niznik, who made me feel I could get my life back – no whining allowed! I worked with Alex every week and was doing so well, I graduated early! It’s been almost five months now, and nothing can stop this old nurse, daughter of a Marine – pain is just weakness leaving the body! I told that to Alex all the time. I really learned from Alex that if you think you can, and stay positive, you can do it! Alex – you ROCK! All my thanks, always, Ann.

In August of 2018 I shredded my patellar tendon jumping trying to win a $2 t-shirt for hitting a volleyball. 10 days later, Dr. Lewis was performing the first surgery to repair the damage. After surgery, I was in an immobilizer for around 12 weeks. During this time, I met with Tegan and Hannah to start physical therapy. During this time therapy went fine. I was able to do straight leg raises fairly quickly and progressed as expected.

The next phase is to start to bend the knee. I equate it as the tendon is like a frozen bungee cord, has to stretch it out. Along the way there were many hurdles, swelling in the knee, tightness in the hamstrings and t band slowed progress as well as the knee already being arthritic . At 1 point I was measured at 80 degrees and was stuck there. After a follow-up with Dr. Lewis he said he believed that scar tissue had built up on the repaired tendon and was keeping me from progressing any farther, so back under the knife I went to clean up the scar tissue and knee manipulation. After that we continued PT 3 times a week and made some progress but again because stuck but now at 90 degrees.

Back to Dr. Lewis for another follow-up. Dr. Lewis was not unsure what was keeping me from bending past 90 degrees and proceeded to give me the bad news. He was unsure if I would be able to walk normal again let alone play sports. This was difficult for me to hear as sports and being active have been my life. If I’m not playing a game I’m coaching a game. At this time this is where Tegan shined! Not only did she continue to push me during my therapy, she helped me with my mental and emotional state! And to be honest that was probably the most important therapy she provided. We continued to work hard, bending and pushing until I couldn’t do more. In my next follow-up I’m proud to say Dr. Lewis said in a couple of months you should be able to run and jump again!!!

Tegan stayed with me the whole time, assisting me to trust my knee as I ran, made cuts and jumped! Last week I played volleyball for the first time since August 27th and it was great! Being able to compete again is such a huge accomplishment for me!!! And without Tegan I strongly believe that I would not have been able to accomplish this!

Thank you Tegan, Hannah and of course Dr. Lewis for helping me get right!!!

I can’t say enough good things about Dr. Lewis and his staff! I’ve had very painful elbow and knee conditions that were addressed with the most conservative care practices first — both of which were highly successful. I’ve been to doctors who go right to surgical options first, but Dr. Lewis guided me to cortisone, physical therapy, and ergonomic solutions that worked wonders. Not only that, he seems genuinely interested in me and has a very kind and reassuring manner.

Dr. Lewis – We want to thank you and your staff for all you did for Mason in surgery on March 13th enabling him to be able to set out on two goals he had going in to that day. He had a personal goal to be back for his first game of his senior football season, August 30th. He also had a team goal to be playing in the Prep Bowl.  He was able to achieve both of those goals, not missing a snap along the way as Lakeville North’s starting left guard. Below is a picture from that first game and then two from their state championship win.

With all of our thanks,

Brian & Jennifer M.

I cannot say enough about how well my experiences were with my knee replacements. From my initial evaluation, developing a plan of action, the cortisone shots, the actual replacements, all the way through to post surgery pain management protocol and follow up visits, Dr. Lewis, Libby, PA and staff were professional yet personable, experts at what they do, and extremely skilled. I am 5 months out from my last knee replacement and just finished a 5.7 mile organized hill-filled walk which I have not been able to do in 3 years. I highly recommend this team!

Would like to thank Dr. Lewis and the excellent staff and especially Nurse Peggy for the care they provided to my brother Jon while having his hip replaced. Amazingly, he was home 24 hours later and is doing very well.

Hi Dr. Lewis and Libby,
A big thank you! The removal of fluid from my right knee and the following injection has been wonderful. We just returned from our trip in France and my right knee continues to be “pain free!” I was amazed at how well my left knee and right hip replacements felt, but more so, how the right knee responded to heavy days of walking in Normandy, the Loire Valley and Paris. Keep up the great work of helping to make people’s lives better!

Extremely happy with the care I received from Dr. Lewis and the entire staff at Twin Cities Orthopedics. Five stars all around! From the receptionist, to the nurses, to the doctor and especially to “Libby” (Dr. Lewis right hand women), I felt in great and confident hands. I run a small business and understand good service, and would strongly recommend this kind and qualified group of medical staff.

On June 26th of 2017, I checked in to The Ridges in Burnsville and Dr. Lewis performed a total knee replacement on my right knee.  My recovery from this surgery has been easier than I expected. The care I received at The Ridges was wonderful. All of the TCO providers, including the Physical Therapists at the Eden Prairie location have been awesome. I couldn’t be happier with my recovery and my follow up visits with Dr. Lewis. I have recommended him to many people.

I was very fortunate to select Dr. Randall Lewis to perform my knee replacement surgery. He is a skilled surgeon that takes the time to listen to your concerns and does his best to eliminate any anxiety you may have. He leads a team of well trained professionals that clearly care for the well-being of their patients.  I am an ordinary guy that was treated like the most important person on earth on the day of my surgery.  From the time I checked in until the time I was discharged from the hospital things could not have gone better.  I am forever grateful to Dr. Lewis and his entire staff!

Today I am 5 weeks post-surgery for my knee replacement. Dr. Lewis did a fantastic job on my knee and of course, we can’t forget about his PA, Libby. The two of them always give me excellent care. Since my progress has been superb, today is my last day of physical therapy. What a team. They have taken care of me for years. Thank you.

Bill R.

Dr. Randall Lewis is great person and terrific surgeon. He listens carefully, answers all your questions, and then delivers the exact surgical results he promises. We have 4 new knee replacements between my wife and myself over approximately 2 years. He restored our ability to walk again without any pain and in reality gave us back our quality of life, as well as a healthy body, positive mind-set, and the ability to participate in all activities we enjoy. He is compassionate, caring, confident in his abilities, and has a fun personality and sense of humor. We recommend him very highly. His PA Libby is also outstanding helping in surgery, recovery, with medication direction , and other post-surgical answers and direction. Her follow-up is flawless with a caring and fun personality and a finely-honed skill set. The two together are a winning combination at the top of their game. Calling them to help you would be one of the best calls you make this year.

Dr. Lewis and Libby Witchger replaced one of my knees in 2008 and the other in 2015. Dr. Lewis is extremely adept at what he does. He is accurate, skilled, caring, and compassionate. He is a patient’s partner in the process of identifying the problem and solving the problem. Both of my surgeries were very successful and I am pain free! Libby and Dr. Lewis are a great team. Libby always returns calls and stays with the patient through the entire recovery process. I highly recommend both of them!

I am writing to express my appreciation for the outstanding care I received from Dr. Randall Lewis, Orthopedic Surgeon and my entire TCO care team including Libby Witchger, PA. For several years I suffered with serious knee issues from sports injuries and arthritis. Initially Dr. Lewis cared for me using non-surgical options.  Ultimately I decided the optimal option was to replace both knees and Dr. Lewis performed the surgeries. Throughout my care experience both Dr. Lewis and Libby impressed me with the personal and genuine care I received. I always received all the information I needed to make informed and clinically sound care decisions based on all options. My surgeries went so well I am now back to walking the golf course, road biking and hiking the national parks. I simply could not recommend a physician and care team more highly.

Darvin K.

Really impressed by the movement I have and how pain free I am since the replacement just 12 weeks ago. Been in Arizona playing golf while carrying my bag just as I did last summer only its now pain-free! Back on the elliptical in the gym with no problems with the leg and knee getting stronger all the time. Thank You Dr. Lewis, you have my vote of confidence!

Debbie J.

Going into my TKR I was nervous but could barely walk and desperately needed the surgery. Dr. Lewis and Libby were fabulous! I had no swelling or bruising and was up and walking around pretty independently by the end of second day. I totally love these two as I have gotten my life back….I can walk again!! Thank you!!

Most people are aware that physical therapists play crucial roles in helping patients recover following injuries or orthopedic surgery. But therapists also work with patients to help them get into better shape before surgery, to shorten the post-surgical recovery time and expedite healing. Eighty-two year old Ann B., of Savage, is a good example. For several years, Ann had been plagued by steadily worsening pain in her right knee (four years earlier, she had undergone arthroscopic surgery to repair her left knee). “The pain had become terrible. I couldn’t walk through the living room without having to brace myself on furniture. I put off the surgery for two years, until I couldn’t bear it any longer.”After consulting with her orthopedic surgeon, Randy Lewis, MD, of Twin Cities Orthopedics, Ann decided to undergo knee replacement surgery, and an Oct. 1, 2010 date was set for the surgery. Dr. Lewis told his patient to expect a recovery period of about six months.In the packet of pre-op information the doctor gave her, Ann read about the importance of exercising prior to surgery, in order to enable a better, quicker recovery. She checked with Mark Froemke, PT, the director of physical therapy at Twin Cities Orthopedics’ Burnsville Clinic, who prescribed a daily exercise regimen she could do at home in the five weeks leading up to her operation.“In two visits prior to surgery we identified her limitations and gave her specific exercises,” Froemke explains. “She went home and did them consistently and that obviously made a difference.”Why are pre-surgical, prescribed exercises so important? “If you can go into surgery with a good range of motion and ability to straighten the knee, that makes rehab easier, quicker and less expensive. For example, if you go into surgery with a loss of 10 degrees in being able to straighten the knee,  having surgery doesn’t mean you will have good extension of the knee,” Froemke notes. “But if you do exercises to stretch the muscles around the knee, that will make it much easier.”Froemke’s examination of the knee indicated she lacked the ability to straighten the knee and also lacked strength in the quadriceps muscles, which support the knee. He suggested gentle, repetitive exercises to increase the knee’s flexibility – extending and bending the leg, and some mild resistance training using an exercise bike, with the amount of resistance appropriate for her physical condition and age.From his perspective, Ann proved to be an ideal patient, Froemke notes. “If you go into surgery with the attitude that you are going to do the exercises the therapist recommends and are consistently motivated – as Ann was – it makes a big difference in recovery.”“The therapists at the Transitional Care Unit (TCU) at the Masonic Home in Bloomington were also surprised at my recovery and I was released early from rehab to home”, Ann recalled. Post release from the TCU, she returned to the therapy clinic at TCO in Burnsville for three more exercise sessions to stretch muscles and improve her flexibility. She walked with a cane for about a week, and then was able to walk unaided, enjoying her annual vacation in Florida with enthusiasm. “I’m better than I thought I could be!”
