Bihar's Innovation

Smallest incision.
Fastest recovery.

The Nano Technique is Dr. Sinha's hallmark contribution to joint replacement in Bihar — a minimally invasive philosophy that reduces biological trauma and maximises recovery speed.

Traditional surgery requires large incisions, significant blood loss, and days before mobilisation. The Nano Technique changes all of this — patients walk in 4 hours and bear full weight from morning of Day 1.
