Welcome to OrthoIllinois!

My name is Mark Barba and I would like to take this opportunity to tell you more about myself, and how I became committed to healthcare. I am a subspecialized orthopedic surgeon with a practice in joint replacement and a special interest in replacements of the hip joint.

When I was growing up, I had a garage full of automotive tools and a father who patiently taught me how they worked. He was also very concerned that I properly cared for the tools and remained disciplined and organized. A place for everything and everything in its place was his lesson — boring for a child, but a great foundation for a surgeon.

I always knew I wanted to be a doctor. I could not understand how a kid would want to be anything else. I needed stitches three times while growing up and loved every visit to the emergency room! In medical school I chose to focus on orthopedics; the instruments just felt natural in my hand, and no one had to tell me which way to tighten a screw.

I chose to further subspecialize in joint replacement because I have a hard time with failure and replacement of an arthritic joint is almost always a victory. I did not see this in any other aspect of medicine I studied. I love it even more now than ever. Joint replacement implants have evolved to provide amazing results. I especially focus on devices that now allow people to return to even higher levels of activity. Ask me about the Birmingham Hip and the Oxford Knee and I think you will be impressed with how far the science of joint replacement has progressed. No matter what the reason for your appointment, I look forward to our visit because it is people that are my motivation. Otherwise, I would probably be working on cars.

Here's what my patients are saying:

The second opinion I scheduled with Dr. Barba was the best decision I could have made. A knee replacement done in 2014 with a different physician in a different city had failed and that doctor could not find the issue. Dr. Barba found the problem immediately. A few weeks later, a revision surgery was done and now six short weeks later at the end of 2015, I am in less pain and have more flexion than I did for the last two years.

At the age of 38, I was told I had arthritis in my hip, and my only option was a hip replacement. I ignored that advice. Dr. Barba was highly recommended by a close personal friend. I met with Dr. Barba as a second opinion shortly before my 42nd birthday. Being a young person for this type of operation, I was reluctant, but not being able to live with the unbearable pain any longer, I decided it was time. I wish I would have done this years ago! Dr. Barba has literally changed my life. I am almost 44, have ...

I started having hip problems at age 52 and went to several doctors in another state, who all told me I was too young for surgery(since "hips wear out.") When I moved to Illinois and connected with Dr. Barba at 62, he said "What are you waiting for? Let's do it." Thank goodness!! I had the right hip done several months later and when the left hip started going bad about 2 years after that, I had that done right away rather than suffer 10 years with it. I feel wonderful!!! I'm walking like I did when I was in ...

Dr. Barba replaced both of my hips last year. Before having my hips replaced, I was in pain 24/7 due to osteoarthritis. Now, after having my hips replaced, I have not had any trouble with my recovery from surgery or with my new joints. I am in my 20s and lead an active life, working as a welder and riding horses as a pastime, so I can assure anyone considering Dr. Barba as a surgeon that he is good at his job because I would not have been able to continue my lifestyle had I not gotten replacements. His bedside ...

wonderful, wonderful surgeon!! Knows exactly what is wrong & fixes it. Have had both hips replaced by him and one knee (wish he'd stop tripping me!). He's always very concerned about me, and I appreciate the time he takes with me.

Thank you to the finest surgeon in all the world, Dr. Mark Barba. You have given me my life back by replacing my hips. You are so professional and you I am so appreciative to you and all of your staff!!!

"I had an anterior right hip replaced and woke up with a pain level of 0!  I went home 24 hours later after walking halfway around the hospital floor and going up and down 11 stairs.  I was limping and in extreme pain before surgery."

"He has the best bedside manner of any doctor that I have experienced in a long time."

"I was amazed at the results.  I had complete hip replacement.  I had virtually no pain after the procedure.  Dr. Barba is amazing."  Anonymous review post on
