What he did for me was almost like a miracle.

My knees had become so painful that I had to walk with a cane and I was on an aggressive pain medication. I was very limited in what I could do and I felt as if the pain was affecting my attitude toward everything. Dr. Ferro is marvelous! I felt relaxed and comfortable with him in the first visit. I was very confident in Dr. Ferro and ...

My knees had become so painful that I had to walk with a cane and I was on an aggressive pain medication. I was very limited in what I could do and I felt as if the pain was affecting my attitude toward everything. Dr. Ferro is marvelous! I felt relaxed and comfortable with him in the first visit. I was very confident in Dr. Ferro and wasn't a bit afraid. What he did for me was almost like a miracle.

Thank you Dr. Ferro for your exceptional medical skills and abilities...

Slowly but surely the pain in your knees robs you of your quality of life. The doctor tells you, "your knees are bone on bone." He answers your questions, then says "take your time and let me know when you are ready for surgery. After surgery your response is, "oh, why didn’t I have both knees replaced years ago!" Pain free to do ...

This is my second NanoKnee Replacement, the first was three years ago, and now one just a week ago. The first one was so much better that I could dreamed it could be, the speed of recovery and much less pain than I thought I could have and when all said and done it is 100% back and there is no feelings that tell me anything was ever do...

This is my second NanoKnee Replacement, the first was three years ago, and now one just a week ago. The first one was so much better that I could dreamed it could be, the speed of recovery and much less pain than I thought I could have and when all said and done it is 100% back and there is no feelings that tell me anything was ever done to my knee.

My new replacement is heading even better than the first. I had a big bow in my leg that was even affecting my ankle and now my leg is straight and no more ankle pain. I have talked to a lot of people who had knees replaced and none can say they are happy with it. I’m proud to say I had my knees done by NanoKnee. Do your research and I know you can’t go wrong with Nano Knee there the best!!

Received the best care and consideration from office personnel, surgical team, Janika NP and Dr Ferro from start to finish. Every facet was organized with prompt follow up to my needs. Now pain free and straight legged after a Total knee replacement for severe knock knee. Unfortunately, a few months later another issue arose not related to my knee… Dr Ferro went out of his way to find me an amazing surgeon.

Highly recommend Dr Ferro and NanoKnee Clinic!

My new knee feels great and I'm looking forward to 30 more years without pain.

The surgery went well, and I was walking without assistance in 4 days. My total recovery is ongoing, but at 3 months I'm back to walking 3 miles on the beach with no pain. My new knee feels great and I'm looking forward to 30 more years without pain.
