Dr. O'Neill replaced both of my hips one month apart. He used the new direct anterior approach. The results were amazing! Little or no pain. I never needed a cane or a walker. I was driving a car in 2 days and mowing my yard in one week. Dr. O'Neill and his staff are top notch. They are kind and explain everything precisely. I HIGHLY recommend Dr. O'Neill to anyone needing orthopedic surgery. You will be extremely pleased with the results!
