I had a bad dirt bike accident that required major knee surgery. Afterwards, my knee stiffened up and that’s when Dr.Bader came in to perform a MUA (manipulation of the knee to regain motion). I’m getting an ACL soon by Dr. Bader, and I’m looking forward to it.

Dr Bader repaired my right shoulder eight years ago and it's still strong and doing well. I moved out of state last year and needed my left shoulder repaired and traveled to California just so Dr. Bader would perform the surgery. He is a caring physician with great surgical outcomes!

Dr Bader was my second opinion to address the meniscal and ligament tear I had in my knee. I was already looking at surgery with another orthopedic Md but Dr Bader did not think that the long term outcomes would be good after surgery and being on crutches for 8 weeks. He offered hyaluronic viscous injections and a special brace to off load my knee. I have chosen to follow his recommendations and am greatly relieved.

Dr. Bader re-attached my healthy, but un-rooted meniscus. I was in a lot of pain before the surgery. It was a creepy idea- drilling my shin bone and using "filament" (or something) to re-seat the meniscus and have it held in place by the filament attached to my shin bone. BUT- It turned out great! I got to keep my own relatively healthy (I am 70) knee and it healed well and I can walk, hike, bike ride etc. without any pain now. I am so happy I didn't have to go the replacement route.

Dr. Bader is a very good Dr. I had left shoulder surgery in September, and to be honest, I didn't have allot of pain after the surgery, the most pain I had was when I started strength training on the shoulder, but other than that, I would recommend Dr. Bader for shoulder, knees, and all.

After a knee started acting up, I tried several times to figure it out with other doctors. Finally, Dr. Semon Bader noticed a chunk of rogue cartilage. He carefully removed it, and repaired a torn meniscus while rummaging around in there. Surgery was minimally invasive, and pain was almost nonexistent. My knee is back in action and I no longer stress about sudden pain when things pop out of place. One note: make sure that your insurance covers the physical therapy there, or make arrangements in advance. I wound up having to wait almost two months to get started with a professional. I managed to figure out my own PT, but it stressed my wife and mother, both. Dr. Bader is a fabulous doctor, and I would definitely seek out his services again. He finally solved my problem!

He's an old school Doctor ,Who practices the latest in medical procedures, not like normal surgeons that want to cut you up to make money. He used the PRP injections to cure my rotator cuff, instead of surgery. I have no pain and full reaching capacity. He is God sent, and I sincerely am grateful that doctors like him still exist.

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 just met Dr Bader today. He's my new ortho shoulder surgeon. He explained my MRI in a way that was easy for me to understand. He also demonstrated a problem with the big muscle that's very close to RC my injury; the pain from it was masked. It makes perfect sense that it should be injured due to how I fell. He spotted it quickly and took action. He immediately inspired my confidence. Now we can get to it.
