Advantages and Disadvantages of Robotic Knee Replacement
Know about the robotic knee replacement, advantages, disadvantages, who is a good candidate, after-surgery support therapy and more.
Introduction
If you or a loved one is considering knee replacement surgery, you may have heard about robotic knee replacement. This advanced surgical technique is becoming increasingly popular, but like any medical procedure, it has its pros and cons. In this article, we’ll break down the advantages and disadvantages of robotic knee replacement in simple terms to help you make an informed decision.
What Is Robotic Knee Replacement?
Robotic knee replacement is a type of surgery where a surgeon uses a robotic arm to assist in performing a knee replacement. The robot does not operate on its own—it works under the surgeon’s control to improve precision and accuracy.
How Does It Work?
1. Pre-Surgical Planning: A 3D model of your knee is created using scans to customise the surgery.
2. Guided Assistance: The robotic arm helps the surgeon make precise cuts and place the implant accurately.
3. Real-Time Adjustments: The robot provides feedback during surgery to ensure optimal alignment.
Now, let’s explore the advantages and disadvantages of this procedure.

Advantages of Robotic Knee Replacement
The advantages of robotic knee replacement include:
1. Greater Precision and Accuracy
The robotic system allows for highly precise bone cuts, ensuring the implant fits perfectly.
Better alignment reduces wear and tear on the new joint, potentially making it last longer.
2. Personalised Surgery
The 3D planning ensures the procedure is tailored to your unique anatomy, improving outcomes.
Customisation helps in restoring natural knee movement.
3. Smaller Incisions and Less Tissue Damage
Robotic assistance allows for minimally invasive techniques, meaning smaller cuts and less trauma to muscles and ligaments.
This can lead to faster recovery and less post-surgical pain.
4. Reduced Risk of Complications
Since the robot helps in precise placement, the chances of implant misalignment or instability are lower.
Lower risk of nerve or blood vessel damage due to controlled movements.
5. Faster Recovery and Rehabilitation
Patients often experience less pain and swelling after surgery.
Many can walk sooner and return to daily activities faster compared to traditional knee replacement.
6. Improved Longevity of the Implant
Better alignment means less stress on the implant, which may help it last longer.
Studies suggest robotic-assisted replacements may have lower revision rates (fewer repeat surgeries).
Disadvantages of Robotic Knee Replacement
While robotic knee replacement has many benefits, there are some drawbacks to consider:
1. Higher Cost
Robotic-assisted surgery is more expensive than traditional knee replacement due to advanced technology.
Insurance coverage may vary, so check with your provider beforehand.
2. Limited Availability
Not all hospitals or surgeons offer robotic knee replacement.
You may need to travel to a specialised centre for this procedure.
3. Longer Surgery Time
The setup for robotic assistance can extend the duration of surgery, though the actual procedure may be more precise.
4. Learning Curve for Surgeons
Surgeons need specialised training to use robotic systems effectively.
Choosing an experienced robotic surgeon is crucial for the best results.
5. Not Suitable for All Patients
Some patients with severe deformities or bone loss may not be ideal candidates.
Your doctor will evaluate whether robotic surgery is right for you.
Who Is a Good Candidate for Robotic Knee Replacement?
You may be a good candidate if:
You have chronic knee pain due to arthritis or injury.
Non-surgical treatments (medications, injections, physical therapy) haven’t helped.
You want a more precise and customised surgical option.
However, if you have:
Severe osteoporosis (weak bones)
Active infections
Poor overall health
Your doctor may recommend alternative treatments.
Recovery Tips After Robotic Knee Replacement
To ensure a smooth recovery:
Follow Physical Therapy – Helps regain strength and mobility.
Use Assistive Devices – Crutches or walkers may be needed initially.
Manage Pain & Swelling – Ice packs and prescribed medications help.
Stay Active (Gradually) – Light walking improves circulation.
Eat a Balanced Diet – Protein and calcium support healing.
Should You Choose Robotic Knee Replacement?
Robotic knee replacement offers greater precision, faster recovery, and better long-term results for many patients. However, it may not be the best option for everyone due to cost and availability.
Final Thoughts
Robotic knee replacement is a modern, effective solution for severe knee problems, but it’s important to weigh the pros and cons with your doctor. With the right guidance, you can make the best choice for your health and mobility.
