CORI robotic-assisted knee replacement at Aster MIMS Kannur — the only centre in Kannur district. Sub-millimetre precision, no CT scan required. Performed by Dr. Vishnu Baburaj, PGI-trained orthopaedic surgeon.
A next-generation surgical platform that brings computer-guided precision to knee replacement — without the drawbacks of older robotic systems.
CORI creates a precise 3D model of your knee during surgery using surface mapping — no preoperative CT scan, no extra radiation, no additional hospital visit.
The robotic handpiece provides haptic boundaries that prevent the surgeon from cutting beyond the planned area — ensuring the implant fits your anatomy precisely.
Unlike fully autonomous systems, CORI keeps the surgeon in control throughout. The robot assists — the surgeon operates. You benefit from both human expertise and robotic precision.
Both approaches are safe and effective. Here is how they compare.
| Feature | Conventional | Robotic (CORI) |
|---|---|---|
| Bone-cut accuracy | Manual jigs (±2-3°) | Robotic guidance (±1°) |
| Preoperative imaging | X-ray only | X-ray only (no CT needed) |
| Soft-tissue balance | Assessed manually | Real-time digital assessment |
| Hospital stay | 3-5 days | 3-5 days |
| Same-day walking | Yes | Yes |
| Best suited for | Most patients | Younger/active patients, complex deformities |
The CORI-assisted procedure at Aster MIMS Kannur, step by step.
Dr. Vishnu Baburaj reviews your X-rays, examines your knee, and discusses whether robotic-assisted surgery is the right approach for your case. Standard X-rays are sufficient — no CT scan is needed.
Once in the operating room, the CORI system maps the surface of your knee joint to build a precise 3D model. This captures your unique anatomy — bone shape, ligament tension, and joint gaps — in real time.
Using the 3D model, the surgeon plans the exact position, size, and alignment of the implant on screen. Adjustments are made until the plan achieves optimal balance and alignment for your knee.
The surgeon uses a robotic handpiece that provides haptic feedback — it physically prevents cutting beyond the planned boundaries. This ensures the bone is prepared to sub-millimetre accuracy, and the implant fits your anatomy precisely.
The implant is placed with precision-verified alignment. Physiotherapy begins on the same day. Most patients are walking with support within hours and discharged within 3-5 days.
Until recently, robotic knee replacement was only available at select hospitals in Kochi, Bangalore, and Chennai. Aster MIMS Kannur now offers the same CORI technology — closer to home for patients in North Kerala, Coorg, and South Karnataka. You get metro-level surgical precision without the travel, accommodation, and follow-up challenges of distant cities.
Patients from Thalassery, Payyannur, Taliparamba, Kasaragod, Wayanad, and Mangalore regularly visit Aster MIMS Kannur for robotic knee surgery.
