Home / Robotic + Nano Technique

First & only robotic programme in the region

Nano access. Robotic accuracy.

Two innovations, one operating theatre. The Nano Technique keeps the surgery small — an incision under 10 cm, muscle-sparing, minimal blood loss. The ROSA® robotic system keeps it exact — computer-guided implant placement matched to your anatomy, millimetre by millimetre.

Meet the robot

What ROSA® actually does in surgery.

Scan
Maps your knee live

ROSA builds a real-time model of your joint during surgery — no extra CT radiation required.

Plan
Personalises the fit

Bone cuts and implant alignment are planned to your anatomy, not a one-size template.

Guide
Guides the surgeon's hand

The robotic arm holds guides at the planned position with millimetre accuracy. The surgeon operates; the robot ensures precision.

Verify
Checks balance before closing

Ligament tension and alignment are verified on-screen — a balanced knee is a natural-feeling knee.

The Nano Technique

Small incision. Smaller footprint on your body.

Pioneered by Dr. Sinha in Bihar, the Nano Technique is a minimally invasive approach to hip and knee replacement. Instead of cutting through muscle, it works between and around it — through an incision under 10 cm.

  • Incision under 10 cmA fraction of a conventional exposure — less tissue trauma, a smaller scar.
  • Muscle-sparing approachMuscles are moved aside, not cut — the single biggest reason recovery is faster.
  • Minimal blood lossMost patients need no blood transfusion.
  • Lower infection riskLess exposed tissue and shorter hospital stays reduce infection opportunity.
  • Walk within 4 hoursFull weight bearing and independent toilet visits from the very next day.

Side by side

Traditional surgery vs the Robotic + Nano programme.

Traditional approachRobotic + Nano Technique
IncisionLarge, extensive exposureUnder 10 cm, muscle-sparing
Implant alignmentManual jigs and visual judgementROSA® robotic guidance, millimetre accuracy
Blood lossHigher; transfusion more likelyMinimal; transfusion rarely needed
First walkOften 1–2 days after surgeryWithin ~4 hours for most patients
Weight bearingGradual, over daysFull weight bearing from day one
Pain & medicationMore tissue trauma, more painLess trauma, markedly less pain
Hospital stayLongerShorter — home sooner, healing at home

Outcomes vary by patient, joint condition and overall health. Suitability for the robotic or Nano approach is confirmed at consultation.

Is this for you?

Made for the patients who fear surgery most.

Advanced arthritis

Knee or hip pain that no longer responds to medicine, injections or physiotherapy.

Elderly patients

Shorter surgery, less blood loss and same-day mobility matter most at higher ages.

Both knees together

Bilateral replacement in one sitting — one anaesthesia, one recovery, one hospital bill.

People who can't stop

Farmers, shopkeepers, homemakers, professionals — anyone whose family depends on them being on their feet.
