I'm a 79 year old woman whose knees had become so bad that I could only walk for short distances without pain. Dr. O'Neill
replaced first one knee and the other three months later. Two months after the second surgery I am able to walk over a mile without pain. I'm able to walk stairs with confidence, stoop to garden and generally back to my previous life. Dr. O'Neill made a huge difference in my life and I would (and have) heartily recommend him as a surgeon.
