Our Patients

"Having been told I needed both of my knees replaced at the age of 57, I knew I had to find the best Orthopedist Surgeon who specialized in Total Knee Replacement. I called the Orthopedic Institute of NJ and they gave me an appointment that very week with Dr. Dundon. Dr. Dundon took Xrays and confirmed that I did need both knees replaced…he was so compassionate and gave me 100% of his attention answering all my questions.

In January 2018 I had my left total knee replacement and let me tell you, I received royal treatment from the pre-op procedures all the way through...I can’t sing my praises loud enough for Dr. Dundon and his team! It is my pleasure to write this review in hopes it helps someone else make the decision to choose the best of the best and have Dr. Dundon do their surgery and bring them from living with pain to being themself again!"
