I had a hip replacement over 6 years ago and have had problems with the hip ever since. I went to about ten different orthopedic surgeons to try and figure out what was wrong and nobody could figure out what the problem was. I went to Dr. O’Neill and he determined what the problem was and performed a hip revision in April 2016. I still have a little muscle soreness but the hip is much improved from before. Unfortunately, I was unable to have the anterior approach performed but a number of people I know did have that procedure with Dr. O’Neill and they had excellent results. Also, the staff at North Memorial were superb.
