I went to Dr. Boettner for my left hip revision. I picked Dr. Boettner from the Vitals website and the good reviews from his past patients. As soon as I meet him I knew that he knew what he was talking about and I like his demeanor. Two years ago he did my revision and he will be replacing my other hip in January 2015. HSS is an excellent hospital and Dr. Boettner is an excellent surgeon.
