VELYS — the imageless robotic knee replacement platform from Johnson & Johnson DePuy Synthes. Personalised, millimetre-accurate surgery without pre-op CT scans, delivered by Dr Hardik Shah in Ahmedabad.
VELYS is Johnson & Johnson's next-generation robotic platform for knee replacement. Launched in India in November 2022, it's now the fastest-growing robotic knee platform in the country, with over 1,000 procedures completed nationally in its first 12 months.
Unlike older robotic systems that require a pre-operative CT scan, VELYS is imageless — it maps your knee's anatomy in real-time during surgery. This means no extra radiation exposure, no additional scan cost, and faster pre-surgical workup. The robot analyses your knee's unique movement patterns and helps Dr Shah achieve precise bone cuts and implant placement.

| Real-Time Mapping | Yes | Yes (CT-based) | Yes | Yes |
| Radiation Exposure | None extra | CT scan radiation | Varies | None extra |
| India Launch | Nov 2022 | 2015 | 2017 | 2019 |
| Adoption Rate (India) | Rapidly growing | Widely established | Established | Growing |
Each platform has strengths — choice depends on surgeon expertise, implant preference, and case specifics.
Recent studies from India tracking the first 1,000 VELYS total knee arthroplasty cases show:
With 15,000+ knee replacements performed across multiple platforms, Dr Hardik Shah chooses the right tool for each patient. VELYS offers a compelling combination: imageless workflow, proven accuracy, and integration with the well-validated Attune implant system — one of the most successful knee implant designs of the last decade.
For patients, the practical benefits are significant: no pre-op CT scan (saves cost and radiation), shorter pre-surgical workup, and the confidence of a technology backed by rigorous clinical validation.
DHS is one of a growing number of Ahmedabad hospitals offering VELYS robotic knee replacement. Dr Shah has performed VELYS cases since the platform's early India rollout.
All major robotic platforms deliver excellent accuracy in experienced hands. VELYS's main advantage is being imageless (no pre-op CT), shorter workflow, and integration with the Attune implant. "Better" depends on your specific case and surgeon's expertise.
Similar price range to other robotic platforms in Ahmedabad — typically ₹3.5L – ₹5L per knee. VELYS may be slightly cheaper since there's no pre-op CT scan cost.
VELYS is designed to work specifically with the Johnson & Johnson Attune knee implant system — one of the most clinically validated modern knee implants.
Yes — VELYS robotic knee replacement is covered by most Indian health insurance policies the same way other robotic knee replacements are. Cashless treatment available at DHS Multispecialty Hospital.
The robotic precision typically translates to faster early recovery — many patients walk aided on day 0, are discharged in 2-3 days, and return to daily activities in 4-6 weeks.
