Patient Reviews

I had hip pain for a year. I wasn’t able to walk up and down stairs without being in pain. Before surgery, I was walking about 3000 steps a day in pain. Now I’m able to walk well over 20,000 steps a day with no pain. Love this Guy.
-OSI Patient
Waited 5 only minutes. He was familiar with my health history, explained the procedure well, answered all my questions thoroughly, and I was done and out the door. Exactly what I needed.
-OSI Patient
Dr. Lohrbach is very informative and makes sure his patients know all that is needed to insure that they have a good understanding and experience with their hip replacement surgery. He takes x-rays at the 6 week surgery checkup and explains and discusses the results with you. He and his well-trained staff contact you before and after surgery to make sure you’re doing okay and there are no problems. I especially like the daily informative and uplifting texts that are sent daily to keep you informed and inspired during your recovery.
