How the Technology Works
1. Pre-Operative 3D Digital Mapping
Prior to surgery, a detailed scan of the affected joint is compiled. Specialized robotic planning software renders a highly accurate 3D model of your bone architecture. Dr. Vikrant uses this model to plan the exact implant size, placement angle, and bone preparation depths.
2. Real-Time Dynamic Ligament Balancing
During the procedure, optical trackers feed real-time kinematic data to the surgical computer. As the joint is moved, the computer calculates ligament tension. This allows Dr. Vikrant to adjust implant parameters dynamically, ensuring a natural-feeling joint with optimal range of motion.
3. Robotic-Guided Execution
The robotic arm provides active feedback and establishes virtual boundaries (haptic zones). The system guides the cutting tool along the pre-planned path with sub-millimeter precision, preventing damage to surrounding ligaments, nerves, or soft tissues.
Key Clinical Benefits
Enhanced Longevity
Highly aligned implants distribute forces evenly, reducing localized friction and mechanical wear, thereby increasing implant life.
Preserved Anatomy
Robotic boundaries ensure only the damaged bone tissue is removed, preserving maximum healthy bone mass.
Reduced Complications
Precision bone cuts and ligament balancing reduce post-operative instability and localized discomfort.
Accelerated Mobility
Minimal muscle dissection and localized tissue preservation allow patients to walk within hours of surgery.

"I was amazed by the haptic feedback boundaries explained by Dr. Vikrant. Knowing the robotic arm would prevent the cutting tool from moving even a millimeter outside the safe zone gave me the confidence to go ahead."

Surgical Technology FAQs
No, the robot is an assistant. The surgery is performed entirely by Dr. Vikrant Sinha Roy. The robotic system provides haptic guidance, ensuring the surgical tools remain precisely within the pre-planned boundaries.
Robotic-assisted surgery may have a slight premium due to advanced software planning and consumables, but it offers better implant longevity, fewer complications, and a faster return to daily activity.
