Robotic Total Knee Replacement in Chennai

Severe knee arthritis can gradually make everyday activities such as walking, climbing stairs, standing for long periods, and getting up from a chair increasingly difficult. When knee pain and stiffness continue despite appropriate non-surgical treatment, total knee replacement may be recommended to restore joint function and improve quality of life.

Robotic total knee replacement in Chennai is an advanced orthopedic procedure that combines established knee replacement techniques with robotic-assisted surgical planning and guidance. The technology helps the orthopedic surgeon assess the knee, plan implant positioning, and perform selected surgical steps with greater precision.

At Shri Bone & Joint Clinic, Dr. Shriram Krishnamoorthy provides evaluation and treatment planning for patients with advanced knee joint damage. The clinic's robotic knee replacement approach uses the VELYS Robotic-Assisted Solution, which supports personalised surgical planning and intraoperative guidance without requiring a preoperative CT scan for the robotic workflow.

What Is Robotic Total Knee Replacement?

Robotic total knee replacement, also called robotic-assisted total knee arthroplasty, is a surgical procedure in which the damaged joint surfaces of the knee are replaced with artificial components using robotic assistance.

The knee joint consists of three main compartments:

• Medial compartment – the inner side of the knee
• Lateral compartment – the outer side of the knee
• Patellofemoral compartment – the area between the kneecap and thigh bone

When arthritis affects multiple compartments and causes significant pain, stiffness, and functional limitations, total knee replacement may be considered.

During the procedure, the damaged surfaces at the ends of the thigh bone and shin bone are prepared and replaced with artificial components. The kneecap surface may also be resurfaced when clinically appropriate.

Robotic assistance helps the surgeon plan and guide bone preparation, assess alignment, and evaluate joint balance during the operation.

Importantly, the robotic system does not independently perform the surgery. The orthopedic surgeon remains responsible for planning, controlling, and carrying out the procedure.

When Is Robotic Total Knee Replacement Recommended?

Robotic total knee replacement may be considered for patients with advanced knee joint damage who continue to experience substantial symptoms despite appropriate conservative treatment.

Severe Knee Osteoarthritis

Osteoarthritis causes progressive deterioration of the cartilage that protects the surfaces of the knee joint.

As cartilage wears away, patients may experience increasing pain, stiffness, swelling, and difficulty with movement.

When arthritis becomes advanced and affects multiple compartments, total knee replacement may be recommended.

Persistent Knee Pain Despite Treatment

Patients who continue to experience significant pain despite appropriate medication, physiotherapy, activity modification, injections, or other non-surgical treatments may require further evaluation.

The decision to proceed with surgery depends on symptom severity, functional limitations, examination findings, imaging, and individual patient requirements.

Difficulty Walking and Climbing Stairs

Advanced knee arthritis can interfere with activities that were previously comfortable.

Patients may struggle with walking, standing, climbing stairs, getting into vehicles, or rising from a seated position.

When these limitations significantly affect independence and quality of life, knee replacement may be considered.

Severe Knee Stiffness and Reduced Movement

Progressive arthritis can reduce the knee's ability to bend and straighten.

Patients may experience difficulty performing everyday movements because of joint stiffness, pain, or deformity.

Knee Deformity Associated With Arthritis

Advanced arthritis may contribute to bow-legged or knock-kneed alignment.

Robotic assistance can help the surgeon assess alignment and plan implant positioning according to the patient's anatomy and surgical requirements.

However, robotic technology does not make every deformity suitable for routine knee replacement. Complex cases require individual surgical assessment.

What Are the Benefits of Robotic Total Knee Replacement?

Robotic-assisted total knee replacement provides additional planning and intraoperative guidance tools that can help surgeons perform selected steps of knee replacement with greater precision.

Potential benefits include:

Personalised Surgical Planning

The VELYS Robotic-Assisted Solution allows the surgeon to evaluate patient-specific knee anatomy and intraoperative measurements.

This information supports individualised planning of bone preparation and implant positioning.

Precise Bone Preparation

Robotic assistance provides guidance during selected bone preparation steps.

This can help the surgeon execute the surgical plan with precision while accounting for the patient's anatomy.

Assessment of Knee Alignment

Correct implant positioning and knee alignment are important considerations in total knee replacement.

Robotic technology provides information that assists the surgeon in assessing and adjusting the surgical plan.

Intraoperative Joint Balance Assessment

The surgeon can evaluate knee movement and soft-tissue balance during the procedure.

Robotic-assisted measurements may help guide adjustments intended to achieve a stable and functional knee replacement.

CT-Free Robotic Workflow

The VELYS system supports robotic-assisted knee replacement without requiring a preoperative CT scan specifically for robotic planning.

Other imaging or investigations may still be required depending on the patient's condition.

Potential for Improved Surgical Consistency

Robotic assistance may improve the precision and consistency of certain technical aspects of knee replacement.

However, improved technical precision does not automatically guarantee less pain, faster recovery, longer implant survival, or better long-term outcomes for every patient.

How Is Robotic Total Knee Replacement Performed?

Robotic total knee replacement involves several stages, beginning with patient evaluation and ending with postoperative rehabilitation.

Step 1: Preoperative Knee Assessment

The orthopedic surgeon evaluates the patient's symptoms, knee movement, deformity, ligament stability, medical history, and previous treatments.

Weight-bearing X-rays are commonly used to assess the extent of arthritis and joint damage.

Additional investigations may be recommended based on the patient's medical condition and surgical requirements.

Step 2: Anaesthesia and Surgical Preparation

The procedure is performed under appropriate anaesthesia.

The surgical team positions and prepares the patient, and the orthopedic surgeon accesses the knee joint.

Step 3: Intraoperative Knee Mapping

The VELYS Robotic-Assisted Solution uses intraoperative information to support surgical planning.

The surgeon assesses the patient's knee anatomy, alignment, and joint characteristics.

This information helps guide the planned bone preparation and implant positioning.

Step 4: Robotic-Assisted Bone Preparation

The damaged joint surfaces are prepared to accommodate the knee replacement components.

Robotic assistance guides selected bone preparation steps according to the surgical plan.

The surgeon remains in control throughout the procedure.

Step 5: Implant Positioning and Joint Balancing

Artificial components are positioned to replace the damaged joint surfaces.

The surgeon evaluates implant fit, knee stability, alignment, range of movement, and soft-tissue balance.

Adjustments may be made when necessary.

Step 6: Final Implant Placement and Closure

Once the replacement components have been positioned and assessed, the surgeon completes the implantation and closes the surgical site.

The patient is subsequently monitored during the immediate postoperative period.

Step 7: Early Mobilisation and Rehabilitation

Depending on the patient's condition and the treating team's protocol, assisted standing and walking may begin early after surgery.

Physiotherapy helps patients progressively regain knee movement, muscle strength, balance, and functional independence.

What Is Recovery Like After Robotic Total Knee Replacement?

Recovery after robotic total knee replacement is a gradual process involving wound healing, pain management, walking practice, physiotherapy, and progressive strengthening.

Although robotic assistance supports surgical planning and execution, recovery still depends on the patient's overall health, preoperative condition, surgical factors, and rehabilitation.

Early Recovery After Surgery

During the initial postoperative period, patients are monitored for pain, swelling, wound healing, circulation, and mobility.

The medical team may encourage assisted walking and gentle knee movement when clinically appropriate.

Patients are also advised about wound care, medications, and precautions.

Walking and Knee Movement

Walking is an important part of rehabilitation after knee replacement.

Patients may initially use a walker or other walking aid before progressing according to their strength, balance, and confidence.

Knee bending and straightening exercises are introduced under professional guidance.

Strengthening and Physiotherapy

Physiotherapy focuses on restoring the function of muscles supporting the knee, particularly the quadriceps.

Rehabilitation may include:

• Knee range-of-motion exercises
• Quadriceps activation
• Gentle strengthening
• Walking practice
• Balance training
• Stair-climbing practice
• Functional movement exercises

The programme is adjusted according to pain, swelling, healing, and individual progress.

Returning to Everyday Activities

Patients gradually return to activities such as walking independently, sitting comfortably, climbing stairs, and performing routine household tasks.

Higher-impact activities and strenuous exercise may require longer restrictions or permanent modifications depending on the surgeon's advice.

How Long Does Recovery Take After Robotic Total Knee Replacement?

Recovery timelines vary between patients. Robotic assistance does not guarantee a particular recovery period.

Recovery Stage	General Expectations
First 1–3 days	Pain management, assisted mobilisation, gentle knee exercises
Weeks 1–2	Wound healing, walking practice, swelling management, physiotherapy
Weeks 3–6	Progressive mobility, strengthening, improved daily activities
Weeks 6–12	Further improvements in walking, endurance, knee movement, and function
3–6 months	Continued gains in strength, confidence, and everyday mobility
6–12 months	Additional improvements in comfort, function, and recovery may continue

These are broad recovery stages rather than fixed milestones.

Some patients progress more quickly, while others need additional rehabilitation because of age, preoperative stiffness, muscle weakness, medical conditions, or postoperative complications.

Regular follow-up with the treating orthopedic surgeon is important throughout recovery.

FAQs

1. What is the difference between robotic total knee replacement and conventional total knee replacement?

Both procedures replace damaged knee joint surfaces with artificial components. The main difference is the use of robotic assistance during surgical planning and selected steps of the operation.

Robotic systems provide additional measurements and guidance that may improve the precision of bone preparation and implant positioning. However, both procedures require an experienced surgeon, appropriate patient selection, and postoperative rehabilitation.

2. Is robotic total knee replacement suitable for severe knee arthritis?

Robotic-assisted total knee replacement may be considered for patients with advanced knee arthritis when total knee replacement is clinically indicated.

The surgeon evaluates the extent of joint damage, knee deformity, ligament stability, medical fitness, and previous treatments before deciding whether surgery is appropriate. Not every patient with knee arthritis requires replacement surgery.

3. Does robotic total knee replacement involve a robot performing the surgery?

No. Robotic-assisted knee replacement is performed by an orthopedic surgeon who remains responsible for planning, controlling, and completing the procedure.

The robotic system provides measurements and guidance during selected surgical steps. It does not independently decide how to operate or replace the surgeon's clinical judgement.

4. Can patients walk after robotic total knee replacement?

Many patients begin assisted standing and walking early after total knee replacement, depending on their medical condition and the surgeon's postoperative protocol.

Walking aids may initially be required. Patients gradually improve mobility through supervised physiotherapy, strengthening, balance training, and regular follow-up.

5. How long does a robotic total knee replacement implant last?

Modern knee replacement implants are designed for long-term use, and many remain functional for 15–20 years or longer. However, implant lifespan varies, and no specific duration can be guaranteed.
