Patient Testimonials


Over a 10 year period I have suffered with knee problems. I had 3 arthroscopic knee surgeries to clean up the knees and trim the meniscus, none of which relieved the pain I had. I even had a series of shots several times that relieved the pain for a few weeks, but as the shots wore off the pain returned.

Through prayer and research I was able to find Dr. David Mack and soon had an appointment to see if I could get relief from my knee pain in both knees. I can tell you that it turned out to be a real miracle.

In January, 2015 Dr. Mack performed a partial replacement on my left knee and within 6 weeks it was completely healed and through physical therapy I had a healthy knee, free of pain. On August 11th Dr. Mack performed a partial replacement on my right knee. This time the knee healed even faster than the right one. I am a 79 year old male and after 5 weeks I was actually able to run on the beach, although my Physical Therapist cautioned against it (after I had already done it). Dr. Mack released me on October 6th and I am pain free in both of my knees. Without question, my knees feel better than they have for the past 20 – 25 years.

Not only has Dr. Mack, and God given me a new lease on life with pain free knees, but his staff, especially Julie, his nurse and Victoria the physical therapist responsible gave special attention to detail and made the entire process flow smoothly.

I highly recommend Dr. David Mack and his method of doing “partial knee replacement” or any other type he may do. I would also recommend that the physical therapy be done according to the doctor’s instructions.

Two weeks ago, as I limped into the hospital for a total knee replacement, I was filled with lots of mixed emotions.

I was quickly made comfortable by a pleasant and efficient staff. Dr. Mack came in to greet me with a cheery, "Good Morning." What seemed like moments later, I woke in the recovery room with little discomfort and a brand new knee!

Needless to say, I am in a state of utter amazement and wonderment at the miracle of modern day medical technology and the doctors, like Dr. Mack, that are contributing to these cutting edge advancements.

Thank you Dr. Mack and staff!

My worries are long gone, and I am looking forward to the next 25 years filled with active, fun-filled, pain free, adventurous living.

My wife and I cannot be more pleased with the entire knee replacement process and procedure. Dr. Mack and his excellent professional and knowledgeable staff kept us informed as to what to expect along each step of the way. The Pre-Op and Post-Op information provided was most helpful and assuring. Attention was paid to every detail of the process, all on an extremely personal and caring level.

The entire experience, from initial examination and diagnosis through rehabilitation, has been handled in a most professional and personable manner. We truly appreciate the efforts of Dr. Mack and his entire staff.

At the age of 44, I never thought I would have to say I had total knee replacement surgery on both knees, but the way Dr. Mack and his staff approached my situation of replacing my partial knee replacements made it a more comfortable decision. Any questions or concerns/fears I had were quickly and professionally answered and assuaged, and I believe that is what made an impact on what I was choosing to do. I am very pleased with the outcome of the surgery, recovery and physical therapy of going through such a major process twice. The pain I had prior to the surgery was gone the day of the surgery, and that was a great feeling.

In the late mid 70's my wife & I spoke with Greg S. and asked him "how they did it"...rode their bikes from Alaska to South America. His response; it's easy, "just do it". Fast forward to last week-end and picture your patient, 4 months after a total patient specific knee replacement, up on his wake board and skiing well. I couldn't be happier with every facet of my choice to have Dr. Mack & his team replace my knee! Everyone from Dr. Mack's office, the surgical team at North Cypress, the caring nurses on the 4th floor, & the energy of the staff at North Cypress Sports Medicine Center were outstanding. So for anyone considering a Dr. Mack knee replacement I'd say "just do it"!

It has been eight weeks since my partial knee replacement and now I realized just how much I was missing. Having it done has made such a difference to my life. For a start my leg is now straight and my knees actually touch! I have started walking and even plan to ride my bike. The most thrilling part is that I am playing and dancing with my grandchildren again.

Thank you Dr. Mack

As a student at Jersey Village HS, Dr. Mack found that I tore ligaments in my ankle in 2002 after reviewing hospital x-rays that didn't look right. Because of him, it has pushed me into becoming an orthopedic surgeon as well. I also want to thank Dr. Mack, because without him I probably wouldn't be running or even walking.

To any prospective partial knee replacement candidates,

A little more than a year ago, my knees caused me an extraordinary amount of pain whenever I stood or walked for any significant amount of time. I had been doing ongoing, extensive research into knee replacement surgury, including a search for surgeons. Fortunately, I found Dr. David Mack. Dr. Mack offered me a partial knee replacement option which I had not known would be a possibility for me. To make a long story short, I agreed and had bilateral partial knee replacement with the ConFormis implants. Before the surgery, It was difficult for me to walk the short distance to Dr. Mack's office from the parking lot. At my year anniversary, I had to park in the far back parking lot and had no problem walking the distance whatsoever. I can now walk as far as I want with minimal to no knee pain. The procedure has provided me with a remarkable improvement in the quality of my life.

Dancing has always played a major role in my life. You can imagine the amount of damage to my knees after 60+ years. The pain was severe and my fear of surgery kept me off the dance floor for a few years.

My family finally persuaded me to try surgery because of the recent technological advances in procedures and recovery time is shorter.

I had a partial knee replacement 3 months ago. I'm recovering quite well and expect to be dancing very soon.

Dr. Mack is my hero and I would encourage anyone who fears knee surgery to give it a try!

Dr. David R. Mack replaced my right hip in June 2009, and my left in October 2010. I am already able to go places and do things on my own again. His excellent staff are very caring and helpful throughout the entire process, including recovery. The out-patient therapy is the best. I am walking very well now and am very pleased to have my life back. Thank you so much Dr. Mack and your great staff! Sincerely,

Judy W


Dr. Mack did reverse total shoulder joint replacement surgery on me with fantastic results. After a serious fall, I was in considerable pain and now a short two months after surgery, I am pain free. Thank you Dr. Mack!!!

Dr. Mack explained the entire procedure to me including possible problems and then answered all my questions. I would highly recommend Dr. Mack to anyone who has a need for orthopedic surgery.

Thank you again Dr. Mack and all of your very knowledge and helpful staff.

Thank you, thank you, thank you, Dr. Mack, your staff, the physical therapy department, and the staff at North Cypress Medical Center.

It is has been 5 months since I had my partial knee replacement with the Comformis IUni. I am totally happy with the results. The surgery went just like Dr. Mack and his staff explained and my recovery has gone along much faster and smoother than I had ever anticipated. When I refer my friends to Dr. Mack I tell them he is just like meeting your next door neighbor. Dr. Mack and his staff are extremely professional but yet very caring.

Recovery at home went very well. The incision healed quickly with no problem. My husband worked during the day, and so I was alone, but I didn't have much difficulty at all. It really amazed me how simple everything was.

Followup visits were rewarding. Dr. Mack told me I was doing very well. I was happy because it seemed like I was progressing very fast toward my goals.

Today I am walking as far as I want everyday. I'm so glad friends referred me to Dr. Mack. They had said a lot of good things about him, and I'm one who can confirm this!

Now I have full use of my knee and it is hard to even find the 4 inch scar. I can walk with no more leg pain, and I am grateful to Dr. Mack for his professional work. I am a senior citizen and consider the procedure easy.
