Comments: I was very nervous about the procedure, but Dr Chen simply explained my options and left it up to me to decide. This was back in February. I went for it and I'm so glad I did. I forgot all the things I used to do that prior to the hip replacement, I no longer could. It certainly made walking on cobble stone and hill in Europe a breeze. Many Many thanks! And a shoutout also to Courtney, she tirelessly answered my many questions. Excellent experience, thank you Dr Chen!!
