What Is Robotic Knee Replacement?

Robotic knee replacement (or robotic-assisted knee arthroplasty) is a modern evolution of conventional knee replacement surgery. The surgeon uses robotic tools and advanced planning systems to improve precision, accuracy, and implant placement consistency. Under the expertise of a skilled robotic knee replacement surgeon in Chennai, this advanced technique ensures better alignment, quicker recovery, and longer-lasting results for patients.

How it works – in steps

1. Pre-operative planning
   A 3D model of the patient’s knee anatomy is generated using imaging (CT, MRI or intraoperative scans). The system helps simulate the ideal implant size, alignment, and bone cuts.
   
2. Intraoperative guidance
   During surgery, the robotic system assists the surgeon in executing the plan, by guiding bone resections or holding instruments within predefined boundaries. The surgeon remains in control.
   
3. Implant placement and balancing
   The robotic system helps ensure the implant is positioned with sub-millimetre accuracy and that soft tissue balancing is optimized for stability.
   
4. Final verification
   After placement, the system may verify alignment, gaps, and function before closure.
   

Types and systems

• Some systems are active (robot performs cut), others are semi-active (surgeon guided by robot).
  
• VELYS (by DePuy / Johnson & Johnson) is one such 4th generation system, which Dr. Arumugam uses.
  
• The advantage of newer robots is less reliance on preoperative CT scans (lower radiation) and more intraoperative flexibility.

Pros and Cons of Robotic Knee Replacement

✅ Advantages

• Enhanced precision & alignment
  Robotic guidance helps achieve better alignment and implant positioning, which correlates with longevity of the prosthesis.
  
• Bone- and tissue conservation
  Because cuts are controlled, less healthy bone or soft tissue is sacrificed.
  
• Reduced soft tissue trauma
  Less collateral injury leads to lesser pain, swelling, and bleeding.
  
• Faster recovery & early mobility
  Many patients mobilize earlier and regain function sooner than traditional methods.
  
• Lower risk of complications
  Due to improved accuracy, risks like uneven wear, loosening, or need for revision may reduce.
  
• Customised implant orientation
  The system factors in individual anatomy and gait to adapt implant placement.
  

⚠️ Limitations / Risks

• Cost
  Robotic surgery tends to cost more because of the technology, consumables, and training overhead.
  
• Learning curve
  Surgeons need experience to fully harness the system; early cases may take longer.
  
• Not suitable for all anatomies
  Severely deformed knees or prior surgeries may pose challenges to robotic navigation.
  
• Dependence on system integrity
  Malfunction or calibration errors, though rare, can lead to intraoperative issues.
  
• Limited long-term data
  While early outcomes are promising, decades-long results are still being studied.
  
• Equipment availability
  Only select high-end centres have the robotics platform, limiting access.
  

Overall, for suitable patients and in skilled hands, the benefits often outweigh the drawbacks. With advancements in technology and experienced specialists performing robotic knee replacement surgery in Chennai, patients can expect safer procedures, quicker recovery, and long-lasting results.

Typical Patient Journey & What to Expect

1. Initial consultation

A detailed medical history, physical examination, and imaging (X-ray, MRI) help evaluate knee damage. If you are a suitable candidate, robotic replacement may be offered.

2. Preoperative planning

A 3D plan is created, with simulations shared with you. Risk optimization (e.g. managing diabetes, hypertension) is done.

3. Surgery day

Under spinal or general anesthesia, surgery takes ~1.5 to 2 hours (depending on complexity). The robotic system guides bone cuts and implant placement.

4. Postoperative care & rehabilitation

• Early mobilization (day 1 or 2) with physiotherapy
  
• Pain control protocols
  
• Monitoring of swelling, wound healing
  
• Gradual strengthening & gait training
  

5. Follow-up & long-term monitoring

Routine checkups and imaging to ensure implant stability, function, and watch for complications.
