Dr. Arshi is a great surgeon! He did a total knee replacement for my mother. He not only performed a great procedure, but he also treated my mother with much care. He answered all our questions with clarity and patience. My mother is very pleased with the procedure and the treatment given by the entire staff.

I had a wonderful experience with Dr. Arshi and his entire team at NYU Orthopedic & Surgery. From the very beginning, Dr. Arshi was caring, supportive, and incredibly professional. He took the time to truly understand my fears and concerns, and his calm, reassuring bedside manner made all the difference. His team was just as impressive—always kind, helpful, and attentive. They clearly explained everything I needed to do before and after surgery, which gave me a lot of confidence going into the procedure. Every question I had was answered with patience and clarity, and I always felt like I was in good hands. Dr. Arshi and his staff were consistently available and responsive, which made me feel well cared for throughout the entire process. I’m extremely grateful for the exceptional care I received and would highly recommend Dr. Arshi and his team to anyone in need of orthopedic care.

I had hip surgery in March and was out of the hospital after 3 day they started therapy at home right away three times a week and then I went to occupational therapy for 20 sessions …and here. I am now going up and down steps to the city and to the city and back.on the subway .. but the best part was the Surgeon. His warmth and concern that I would be 100% was so encouraging for me to believe that everything he told me he was right on Dr Arshi.i recommend to anyone whoever is in my position and needs a hip replacement. Thank you Dr again.❤️
