Knee replacement surgery has been transforming lives for over 50 years. But in the last decade, robotic-assisted surgery has revolutionized how it is performed—combining the surgeon’s expertise with the sub-millimeter precision of robotic technology.
At COJRI, we use robotic and computer-assisted surgical systems to plan and execute robotic knee replacement with a level of accuracy that is simply not possible with traditional methods. Here is why this matters for your outcome.
What Is Robotic-Assisted Knee Replacement?
Robotic-assisted surgery is not a procedure performed by a robot. The surgeon remains in complete control at all times. The robotic system acts as a highly sophisticated navigation and precision tool—creating a 3D digital model of your knee and guiding the surgeon to execute the preoperative plan with sub-millimeter accuracy.
Real-time feedback during surgery ensures optimal implant alignment, ligament balancing, and bone preparation — results that are difficult to consistently replicate by hand alone.
Traditional vs Robotic Knee Replacement—The Difference
| Aspect | Traditional Technique | Robotic-Assisted at COJRI |
| Planning accuracy | Manual X-ray templating | 3D digital model of your knee |
| Bone cut precision | ±2–3mm variation | ±0.5 mm precision |
| Ligament balancing | Surgeon experience only | Real-time computer feedback |
| Implant alignment | Manual cutting guides | Robotic arm-guided placement |
| Soft tissue protection | Standard retraction | Minimised trauma with precision |
| Recovery | Standard timeline | Often faster — less soft tissue damage |
Key Benefits of Robotic Knee Replacement at COJRI
- Sub-millimetre accuracy in bone cuts ensures the implant sits in the optimal position for your unique anatomy
- Personalized surgery—every patient’s knee geometry is different; robotic planning ensures yours is tailored exactly
- Faster recovery — precise cuts mean less trauma to bone and soft tissue, reducing swelling and healing time
- More natural-feeling knee—optimal alignment produces a joint that feels closer to your original knee
- Longer implant life — correctly aligned implants experience significantly less wear over time
- Less blood loss—precision minimises unnecessary bone removal and adjacent tissue damage
| COJRI’s Robotic Experience Our team has performed hundreds of robotic-assisted procedures. Combining Dr. Sandeep Gupta’s 15,000+ surgeries experience with robotic precision represents the gold standard of total knee replacement care in North India. |
The COJRI Robotic Procedure — Step by Step
- Pre-operative knee mapping creates an accurate 3D digital model of your joint
- Surgeon plans exact cuts and implant positioning digitally before the procedure begins
- During surgery, the robotic arm guides cutting instruments—if movement strays outside the planned safe zone, the system automatically stops
- Real-time soft tissue balancing data ensures natural movement after surgery
- Final implant placement verified by the system before wound closure
Who Is Suitable for Robotic Knee Replacement?
Robotic assistance is appropriate for most patients requiring primary or revision total knee replacement. It is particularly advantageous for younger patients who want maximum implant longevity, patients with knee deformity or complex anatomy, those with high post-operative activity goals, and revision cases. At COJRI, our surgeons assess every patient individually.
Frequently Asked Questions
Q: Does the robot perform the surgery?
A: No. The robotic system is a guidance and precision tool — the surgeon makes every decision and performs every step. The robot enhances human precision, it does not replace it.
Q: Is robotic knee replacement more expensive?
A: Yes, due to the additional technology involved. However, given superior alignment, reduced revision rates, and longer implant life, it represents excellent long-term value. Contact COJRI for a detailed cost breakdown.
Q: Is recovery different after robotic knee replacement?
A: Many patients report faster recovery due to reduced soft tissue trauma. The overall timeline is similar to traditional TKR but with typically less swelling and pain in the first 2 weeks.
Q: Is robotic knee replacement available in Chandigarh?
A: Yes. COJRI at Max Super Speciality Hospital, Mohali offers robotic and computer-assisted knee replacement — one of the few centres in the Chandigarh Tricity region with this capability.
Q: What is the precision advantage of robotic surgery?
A: Studies show robotic-assisted TKR achieves optimal alignment in 97%+ of cases versus 75–85% with traditional techniques. Superior alignment directly correlates with better long-term patient outcomes and implant longevity.
