- I am a physical therapist and have had experience working with total joint patients. When the time came when I needed a hip replacement myself, I picked the best, Dr Nyack. He performed an anterior approach robotic replacement during the restrictions of Covid. He organized an at home monitoring system that allowed him to know my vitals without requiring that I come in unless they saw a problem. I also had some additional medical issues that could have caused a complication or a poor outcome. He addressed each one and my progress was smooth and uncomplicated. I am pain free, and healthier than ever because I am no longer restricted from doing all that I love to do.
