Robotic-assisted knee replacement surgery is an advanced treatment option for patients with severe knee arthritis and persistent pain that significantly affects daily activities and overall quality of life. When conservative treatments such as physiotherapy, medication, injections, and lifestyle modification no longer provide adequate relief, knee replacement may be considered to restore mobility and reduce chronic discomfort.
Dr. Meshram performs robotic-assisted knee replacement surgery using Johnson & Johnson’s VELYS™ Robotic-Assisted Solution. This technology enhances surgical precision through data-driven planning and real-time intraoperative guidance. While robotic assistance improves accuracy and consistency, the procedure remains entirely surgeon-led. Clinical expertise, anatomical understanding, and intraoperative judgement guide every stage of surgery.
Understanding Advanced Knee Arthritis
Knee replacement surgery is typically recommended for patients with advanced osteoarthritis, rheumatoid arthritis, or post-traumatic arthritis. These conditions lead to progressive cartilage loss, joint space narrowing, bone deformity, and chronic inflammation.
Common symptoms include:
Persistent knee pain during walking or standing
Morning stiffness
Swelling
Reduced range of motion
Difficulty climbing stairs
Night pain disturbing sleep
Progressive bow-leg or knock-knee deformity
When joint degeneration becomes severe and affects independence, surgical intervention may offer long-term relief and improved function.
What Is Robotic-Assisted Knee Replacement?
Robotic-assisted knee replacement integrates advanced technology into conventional joint replacement surgery. The VELYS™ Robotic-Assisted Solution supports personalized surgical planning and precise implant placement.
It is important to clarify that the robotic system does not perform surgery independently. The surgeon controls all steps of the procedure. The robotic platform provides real-time data, measurement tools, and guidance that enhance accuracy.
The system assists in:
Creating a patient-specific surgical plan
Assessing joint alignment
Mapping bone anatomy intraoperatively
Guiding precise bone preparation
Supporting accurate implant positioning
This level of precision aims to optimize joint mechanics and implant longevity.
Individualised Joint Alignment
Every knee joint is unique. Factors such as bone structure, ligament balance, and pre-existing deformity vary between individuals. Robotic technology allows for individualized alignment strategies tailored to each patient’s anatomy rather than applying a uniform alignment model.
During surgery, the robotic system helps assess:
Natural joint alignment
Soft tissue balance
Bone geometry
Flexion and extension gaps
This information allows for fine adjustments to achieve balanced knee mechanics.
Personalized alignment may contribute to:
Improved joint stability
More natural knee movement
Enhanced patient satisfaction
However, final decisions remain under the surgeon’s control.
Precision-Guided Implant Positioning
Correct implant positioning is critical in knee replacement surgery. Even small alignment deviations may affect joint mechanics and long-term outcomes.
The VELYS™ system supports:
Accurate bone resection
Controlled implant placement
Consistency in execution
Precision-guided implant positioning may help reduce variability and improve reproducibility across cases. Accurate placement can support:
Better load distribution
Reduced implant wear
Improved functional outcomes
Despite technological assistance, surgical expertise remains the most important determinant of success.
Improved Consistency in Surgical Execution
One of the advantages of robotic assistance is enhanced intraoperative consistency. The system provides real-time feedback that helps confirm surgical accuracy before final implant placement.
This structured guidance may:
Reduce the likelihood of alignment errors
Support balanced ligament tension
Improve overall surgical reproducibility
However, it is essential to understand that technology supports — but does not replace — clinical judgement.
Surgeon-Led Procedure with Technological Support
Robotic-assisted knee replacement is entirely surgeon-led. The robotic platform functions as a precision tool controlled by the operating surgeon.
Dr. Meshram’s role includes:
Evaluating patient suitability
Planning surgical strategy
Performing bone preparation
Assessing soft tissue balance
Making intraoperative adjustments
Ensuring implant stability
Technology enhances accuracy and data interpretation, but surgical decisions are based on clinical expertise and experience.
This balanced integration of technology and surgical judgement ensures that patient safety remains the top priority.
The Surgical Process
The procedure generally involves:
Pre-operative evaluation and imaging
Detailed surgical planning
Intraoperative mapping of knee anatomy
Precision-guided bone preparation
Implant placement
Stability and alignment verification
Post-operatively, patients begin structured rehabilitation aimed at restoring mobility and strength.
Recovery and Rehabilitation
Recovery after robotic-assisted knee replacement is similar to conventional knee replacement, though some patients may experience improved early functional confidence due to precise alignment.
Rehabilitation focuses on:
Pain and swelling control
Range-of-motion exercises
Progressive strengthening
Gait training
Gradual return to daily activities
Adherence to physiotherapy protocols plays a major role in achieving optimal outcomes.
Long-term success depends on:
Proper implant positioning
Muscle strengthening
Weight management
Regular follow-up
Who May Benefit from Robotic-Assisted Surgery?
Robotic-assisted knee replacement may be considered for patients with:
Advanced osteoarthritis
Significant joint deformity
Persistent pain despite conservative treatment
Functional limitation affecting quality of life
Suitability is determined after detailed clinical evaluation and imaging assessment.
Not all patients require robotic assistance, and the decision is based on individual anatomical and clinical factors.
Evidence-Based and Patient-Centered Care
Robotic knee replacement represents an advancement in orthopaedic surgical technology. However, outcomes depend on comprehensive care — from diagnosis to rehabilitation.
Dr. Meshram emphasizes:
Accurate clinical evaluation
Conservative-first treatment approach
Clear surgical indications
Transparent discussion of risks and benefits
Structured post-operative follow-up
The integration of robotic technology is used when it supports precision and personalized alignment, while maintaining surgeon control at every stage.
Core Principles of Robotic Knee Replacement
Robotic assistance supports:
Individualised joint alignment
Precision-guided implant positioning
Improved consistency in surgical execution
The procedure remains surgeon-led, with technology enhancing accuracy while clinical judgement remains central.
Commitment to Precision and Long-Term Outcomes
The goal of robotic-assisted knee replacement is to relieve pain, restore alignment, and improve long-term joint function. By combining advanced surgical technology with clinical expertise and structured rehabilitation, treatment aims to deliver reliable, patient-focused outcomes.
Patients are encouraged to undergo thorough consultation to determine whether robotic-assisted knee replacement is the appropriate option for their condition and lifestyle goals.
