Know All About Robotic Knee Replacement Surgery
Knee replacement surgery is a common treatment for severe arthritis or knee damage when medication and other therapies no longer provide relief. In recent years, robotic-assisted knee replacement surgery has emerged as an advanced technique that improves precision, reduces recovery time, and enhances patient outcomes compared to traditional methods.
🔹 What is Robotic Knee Replacement?
Robotic knee replacement is a procedure where a surgeon uses a robot-assisted system to perform knee replacement with greater accuracy.
The robot does not replace the surgeon; it assists in planning and guiding the procedure.
A 3D model of the knee is created before surgery, allowing for a personalized surgical plan.
During surgery, the robotic arm helps the surgeon remove damaged bone and cartilage and place the implant with extreme precision.
🔹 Benefits of Robotic Knee Replacement
Higher Accuracy – Implants are positioned with millimeter precision.
Personalized Surgery – Tailored to the patient’s anatomy and movement.
Less Pain & Blood Loss – Smaller incisions and less tissue damage.
Faster Recovery – Patients often return to normal activities sooner.
Lower Risk of Complications – Reduced chances of implant misalignment and wear.
🔹 Who Needs It?
Robotic knee replacement is recommended for patients with:
Severe osteoarthritis or rheumatoid arthritis
Chronic knee pain not relieved by medicines, injections, or physiotherapy
Difficulty walking, climbing stairs, or performing daily activities
Knee deformities such as bow legs or knock knees
🔹 Procedure Steps
Pre-Surgical Planning – A CT scan or 3D imaging is done to create a detailed model of the knee.
Customized Surgical Plan – The robotic software maps out exactly where to cut and place the implant.
Surgery Day – The surgeon controls the robotic arm to remove damaged bone and cartilage.
Implant Placement – The artificial joint is placed with the help of robotic guidance.
Recovery Phase – Early mobilization, physiotherapy, and follow-up care.
🔹 Risks and Considerations
Like any surgery, robotic knee replacement has some risks, including:
Infection
Blood clots
Implant loosening (rare with robotic precision)
Higher cost compared to traditional surgery
🔹 Recovery Timeline
Hospital Stay: 1–3 days (sometimes same-day discharge)
Walking with Support: Within 24–48 hours
Physiotherapy: Essential for 6–12 weeks
Back to Normal Activities: Usually 6–12 weeks, depending on individual progress
🔹 Cost & Availability
Robotic knee replacement is more expensive than traditional methods due to advanced technology.
Available in specialized hospitals and orthopedic centers worldwide.
✅ Bottom Line: Robotic knee replacement surgery is a modern, safe, and highly precise treatment for severe knee arthritis or damage. It offers better accuracy, faster recovery, and longer-lasting results — though cost and accessibility may vary.
