Dr Umlas replaced both my hips 13 years ago. They are the same today as when he put the implants in. Absolutely perfect. He is an excellent surgeon. Never had a problem after surgery. No Pain. Was able to walk easily. I asked he to make my hips perfect so I would not be even one millimeter off and he did. I am perfectly even on both hips. Sometimes you can tell a person had hip surgery because they limp a bit, but Dr Umlas always will make you as even as he can. Highly recommend him.
