in Lindenwold nj |
Thank you Dr. Mariani for taking the time to explain things to me about my knee. I am so happy that Dr. Friedman sent me to see you.
in blackwood |
Dr.Mariani did the wrong surgery on my right knee. I conveyed my rheumatologist's message that I needed a knee replacement NOT arthroscopic surgery. He hesitated when I said that as if he were afraid of doing knee replacement. I trusted him and he ended up removing the little cartilage I had on one side of the knee. I suffered tremendously, limped, had excruciating pain for almost one year. After many visits to see him he turned to me and said" Can you leave with what you have left??I

Absolutely one of the best doctors I have ever dealt with. I recommend him to others all the time. Great bedside manner and a top notch surgeon.
