Robotic Assisted Knee Replacement
Robotic-assisted knee replacement surgery is an advanced procedure that uses computer-guided technology to help the surgeon perform knee replacement with exceptional precision. The robotic system creates a detailed 3D model of your knee, allowing for a highly accurate plan that is tailored to your unique anatomy. This ensures the implant is positioned and aligned as precisely as possible, improving joint function and potentially enhancing long-term outcomes.
​
This type of surgery is typically recommended for patients with arthritis or damage to the knee joint that causes pain, stiffness, or reduced mobility, especially when symptoms have not improved with non-surgical treatments such as physiotherapy, medication, or injections.
The aim of robotic-assisted knee replacement is to relieve pain, restore movement, and improve overall quality of life, while maximising the natural feel and function of your new knee. Because the robotic system allows for smaller, more accurate adjustments, many patients experience less soft tissue trauma, reduced pain, and a quicker recovery compared to traditional techniques.
​
Most patients are able to walk with support shortly after surgery, and recovery progresses gradually over the following weeks. Physiotherapy plays an important role in regaining strength, flexibility, and balance.
If you are experiencing ongoing knee pain or stiffness, you can complete the Oxford Knee Score, a short questionnaire that helps assess how much your knee symptoms are affecting your daily life.
Frequently Asked Questions - Robotic Assisted Knee Replacement Surgery
1. What is robotic-assisted knee replacement surgery?
Robotic-assisted knee replacement surgery uses advanced computer-guided technology to help the surgeon perform knee replacement with exceptional precision. A 3D model of your knee is created from scans, allowing the surgeon to plan the exact placement and alignment of the implant. The robotic system assists in executing this plan accurately, helping restore knee function and improve long-term outcomes.
​
2. Who is suitable for robotic-assisted knee replacement?
This surgery is usually recommended for patients with knee arthritis or damage causing pain, stiffness, or reduced mobility, particularly when non-surgical treatments such as physiotherapy, medication, or injections have not provided relief. Your surgeon will review your symptoms, medical history, and imaging to determine if robotic-assisted surgery is appropriate for you.
​
3. How does robotic-assisted knee replacement differ from traditional knee replacement?
In traditional knee replacement, the surgeon manually positions the implant based on experience and measurements. In robotic-assisted surgery, the robotic system provides real-time guidance and precision, improving implant alignment and soft tissue balance. This can result in a more natural feel, less tissue trauma, and potentially quicker recovery.
​
4. What are the benefits of robotic-assisted knee replacement?
The procedure can significantly reduce pain, improve mobility, and restore knee function. The robotic system allows for smaller, more precise bone cuts, which may lead to less discomfort after surgery, a quicker recovery, and more natural knee movement.
​
5. What are the risks or downsides?
As with any surgery, there are risks such as infection, blood clots, stiffness, small risk of pin site fracture or implant issues. While robotic-assisted surgery offers greater precision, it does not eliminate the general surgical risks, and further treatment may be needed in rare cases. Your surgeon will discuss all possible risks before the procedure.
​
6. How long is the recovery period?
Most patients start walking with support within a day of surgery. Physiotherapy is important to restore strength and movement. Many people can return to normal daily activities within 4–6 weeks. The majority of recovery takes place during the first 3 months, with continued improvement for up to a year, depending on your overall health and progress.
​
7. When can I return to sports or exercise?
Low-impact activities such as walking, swimming, or cycling are generally safe after recovery. High-impact activities, including running or jumping, should be avoided to protect the implant and ensure its longevity.
​
8. How long does a robotic-assisted knee replacement last?
Modern implants can last 15–20 years or more. The longevity depends on factors such as age, activity level, and weight. Regular follow-up appointments help monitor the knee’s function and ensure long-term success.
​
9. Will I have a scar?
Yes, there will be a small scar on the front or side of the knee where the incision is made. The scar is usually neat and fades over time.
​
10. How do I find out if robotic-assisted knee replacement is right for me?
Your surgeon will review your symptoms, medical history, and imaging to determine if robotic-assisted knee replacement is suitable. This approach may be recommended when precision placement and optimal knee function are important for your recovery and long-term mobility.
