Robotic Knee Replacement Surgery: A Breakthrough in Joint Care

Knee pain caused by arthritis is one of the leading reasons patients above 50 years seek medical help. As arthritis progresses, the cartilage, meniscus, and joint surfaces gradually wear down, leading to pain, stiffness, deformity, and difficulty walking. When conservative treatments no longer provide relief, knee replacement surgery becomes the best solution.

Over the past decade, joint replacement has advanced dramatically with the introduction of robotic-assisted technology. At Lokmanya Hospitals, Pune, we perform robotic-assisted total knee replacement surgeries that combine surgical expertise with artificial intelligence-driven precision.

What is Knee Replacement Surgery?

Knee replacement surgery involves replacing the damaged or worn-out surfaces of the knee joint with artificial implants. The procedure removes only the diseased cartilage and bone at the ends of the femur (thigh bone) and tibia (shin bone), replacing them with:

• Metal covers for durability
• Highly cross-linked polyethylene inserts for smooth movement

This restores normal joint function, reduces pain, and improves mobility.

Conventional vs. Robotic Knee Replacement

For more than 15 years, surgeons have been performing knee replacement surgeries using conventional techniques. While effective, these procedures rely entirely on manual alignment and measurement.

Since 2016, robotic-assisted knee replacement has revolutionized the process. Robotic systems act as an advanced partner in the operating theater, providing unparalleled precision and safety.

How Does Robotic Assistance Work?

Robotic-assisted systems use artificial intelligence and advanced sensors to help surgeons perform highly accurate procedures.

• Meticulous mapping: Creates a 3D model of the patient’s knee for precise planning.
• Accurate bone preparation: Robotic arms assist in drilling and cutting only the diseased surface.
• Better alignment: Ensures implants are placed in the most natural position.
• Controlled accuracy: Robotics prevents unnecessary bone or tissue damage.

Think of robotics as a faithful assistant that enhances the surgeon’s skills, ensuring better outcomes for every patient.

Advantages of Robotic Knee Replacement

Robotic-assisted surgery offers several benefits compared to conventional methods:

1. Smaller incision and less bleeding
2. Minimal soft tissue dissection
3. Reduced post-operative pain
4. Shorter hospital stay (2–3 days vs. 5–7 days)
5. Faster recovery – patients can walk with support the very next day
6. More natural knee movement due to better alignment
7. Lower risk of complications

Recovery After Surgery

• Day 1 post-surgery: Patients are encouraged to walk with a walker or sometimes even without support.
• Hospital stay: Typically 2–3 days with robotic surgery.
• Rehabilitation: Structured physiotherapy helps restore mobility and strengthen the joint.
• Return to normal life: Most patients resume daily activities within weeks, with improved long-term joint function.

Final Thoughts

Robotic-assisted knee replacement surgery is truly a boon in orthopedic care. By combining surgical expertise with artificial intelligence, it ensures greater precision, faster recovery, and better quality of life for patients suffering from advanced arthritis.

If knee pain is affecting your ability to walk, work, or enjoy life, consult a joint replacement specialist to explore whether robotic-assisted knee replacement is the right option for you.

Frequently Asked Questions (FAQs)

1. Who is a candidate for robotic knee replacement?
Patients with advanced arthritis (stage 3 or 4) who experience pain, stiffness, or deformity despite conservative treatments are ideal candidates.
2. Is robotic knee replacement better than conventional surgery?
Yes. Robotic-assisted surgery offers better precision, smaller incisions, faster recovery, and more natural joint function.
3. How long is the recovery after robotic knee replacement?
Most patients start walking the next day and recover significantly within 6–8 weeks, with continued improvement over months.
4. Is robotic surgery safe?
Absolutely. Robotics enhances the surgeon’s accuracy. The surgeon remains in control at all times, while robotics acts as a precision guide.
5. Will I need physiotherapy after robotic knee replacement?
Yes. Physiotherapy is essential to regain strength, flexibility, and full joint function, even though recovery is faster with robotics.
6. How long do robotic knee implants last?
Modern implants can last 15–20 years or longer, depending on activity level, weight, and lifestyle.
7. Can both knees be replaced at the same time?
Yes, if the patient’s health condition allows, bilateral robotic knee replacement can be performed safely with excellent outcomes.
