About Dr Bader
I destroy body parts. My last incident involved my left knee. Tore everything! So far, physical therapy is going great which means the surgery was fantastic! Thanks Dr. Bader!!
I had my partial knee replacement surgery with Dr Bader on June 2022. I highly recommend him! He is very knowledgeable! He patiently listened and answered all my questions and concerns regarding my surgery. He was great with all my follow up appointments after surgery!
Very good and awesome place I could not have asked for more better care then what they gave me excellent service. I'm very pleased with the overall service and care they gave me.i would recommend this place to anyone if you want good service go here Thank you Dr Semon Bader.
My experience at the office was good. I’m just awaiting approval to have my meniscus repaired. I’m looking forward to having it repaired.
We had a lot of problems with communication with reception here, but everyone seemed nice and understanding. However, the doctor I saw was great and incredibly helpful. All in all, the good outweighed the bad.
I had surgery to repair a torn meniscus root on my left knee. The surgery seems to have gone well although I was advised that I had arthritis that might affect my recovery. It has been three months on and I have Physical Therapy twice weekly which is absolutely necessary to strengthen the muscles in the leg. You also need to be consistent and do assigned home exercises as well. While sometimes frustrated that the recovery process is slower than expected, I am becoming increasingly more mobile and confident with less fatigue. Dr.Bader is a well qualified orthopedist who is well versed in this procedure. He answers your questions directly and offers options as to what procedure to have that may be best suited for your particular injury.
I had surgery on my left knee but the Doctor completely botched it. I was referred by my doctor, Dr Khelia over to the orthopedic specialist, Dr. Bader. I was very glad my doctor said he lived breathe in digested orthopedics that he was phenomenal! So happy to have him now. He did both of my son knees and he is perfectly fine now. I now have a tear in my meniscus in my right knee. And after my first experience, I was scared to death to ever do operational any again, but I’m very confident that if this has to happen. I am absolutely with the right doctor. He’s amazing.
I have been seeing Dr. Bader for knee issues for about 15 years., He is kind, compassionate, conscientious, a good surgeon, and also receptive to non-surgical interventions. He has my total respect and confidence.
Dr. Bader explained with precision the diagnose with my labrum and meniscus issue. Offered paths with several options to proceed with. Greatly recommended.
Thank you Dr.Bader for your surgery my shoulder for my rotated cup. My hands is much feel better now and I can go back to work and I can do my job back again.

Reviews Mean So Much!
Reviews mean so much to both the doctor providing care as well as to prospective patients. We appreciate your reviews!
Both my surgeries were done by Dr Bader and he did a great job. He monitored my progress and ordered the appropriate physical therapy. He is very knowledgeable and takes great care of his patients.
Doctor Bader has been my specialist for two separate problems, a frozen shoulder and a torn ACL. In both of these situations he has taken wonderful care of me.
In my opinion he has amazing surgical skills to have repaired my knee in which pretty much everything was completely torn. I’m so glad I found him when I needed him. Excellent doctor!
