I saw Dr. O'Brien in the summer/fall of 2017. I was having calf pains and thought they were related to a bone fusion I had previously (hence, why I visited an orthopedic). During the physical exam, Dr. O'Brien put one hand on the inside of my right knee, and the other hand on the outside of my right ankle. He proceeded to push outward on my knee and inward in my ankle in what can only be described as a sudden, jerking motion. My knee and ankle both popped audibly and I could not believe that he had done that. He told me he needed to "see what my knee felt like" after the fusion surgery I had done previously. I was upset and in pain. Dr. O'Brien quickly denied that he had caused any damage and seemed immediately concerned with litigation rather than caring for me (for the record, I have not taken nor do I intend to take any legal action). This episode caused chronic pain and popping in my knee and chronic pain/crunching in my ankle. I saw 4 more orthopedics over the course of the last year and a half, had 3 MRIs, and an EMG done. Finally, an orthopedic surgeon recommend that I go to the Steadman Clinic in Vail, CO to help with the chronic pain. The specialist there was able to operate on my knee and resolve the issues. The takeaway of my story and the reason I am writing this review (something I rarely do) is to warn people against seeing Dr. O'Brien. He damaged my ankle and knee during what should have been a routine physical exam and was unsympathetic when I told him so. He has caused me chronic pain for over a year and a half and cost me thousand I medical bills. read more
