Dr. DiFelice and his team has been incredible throughout this entire process. I have never felt this sense of security with any other Dr./facility and I couldn’t imagine going anywhere but HSS for my knee surgery/care.

Dr. DiFelice is outstanding, explains everything to be done and what was done.
His office staff is extremely courteous and friendly as soon as you walk in the door.
The HSS hospital staff could not have been nicer to me and my family. Fantastic treatment from beginning to end. Highly recommended.

I am very happy with the care I receive from Dr. DiFelice and his staff. My knee replacement surgery has enabled me to live my life again as I had in the past. I am so grateful!

Dr.DiFelice comes highly recommended by a few friends. Previous physical therapists say there is no better hospital than HSS to do this surgery
