About the Doctor

A Pioneer in
Joint Replacement Surgery

Dr. Amit Kumar Sinha is the first National Board Certified Joint Replacement Surgeon in entire Bihar and a pioneer in the minimally invasive Nano Technique in joint replacement surgeries — ensuring best results with minimal incision, minimal blood loss, minimal chances of infection, and faster return to daily activities.

Using this technique, Dr. Sinha enables patients to become mobile as soon as 4 hours after surgery, with full weight bearing and independent activity from the very next day — making hip and knee replacements a painless experience.

He is the proud author of the world's largest series on management of infected knees after multiple revision knee surgeries, and the world's largest series for distal femur non-unions. He has peer-reviewed over 50 papers for the Indian Journal of Orthopedics.

The Nano Technique
Difference

Dr. Amit Kumar Sinha is Bihar's pioneer in the Nano Technique for joint replacement surgeries — a minimally invasive approach that transforms the patient's surgical experience.

Traditional joint replacement surgery involves large incisions, significant blood loss, prolonged hospital stays, and weeks before patients regain mobility. The Nano Technique changes all of this.
