Robotic knee surgery for arthritis
Knee arthritis is a common condition that causes pain, stiffness and reduced mobility, affecting quality of life. It often develops gradually and may result from ageing, injury, or joint wear and tear. When non-surgical treatments such as medication, physiotherapy, or lifestyle changes no longer provide relief, surgery might be necessary. One of the most advanced surgical options available today is robotic knee surgery, which provides enhanced accuracy and better outcomes for arthritis patients.
What is arthritis of the knee?
Arthritis of the knee typically involves the breakdown of cartilage within the joint, causing bones to rub together. The most common types include:
- Osteoarthritis: The most prevalent form, linked to ageing and joint overuse
- Rheumatoid arthritis: An autoimmune condition affecting joint linings
- Post-traumatic arthritis: Resulting from previous injury to the knee
Symptoms include pain, swelling, reduced flexibility, and difficulty walking. If left untreated, arthritis can severely limit daily activities.
How does robotic knee surgery work?
Robotic knee surgery uses state-of-the-art technology to assist the surgeon in performing joint replacement procedures with high precision. The robot does not operate independently — instead, it is a tool guided by the surgeon.
Before surgery, 3D imaging is used to develop a detailed map of the patient’s knee. This allows for a customised surgical plan tailored to the individual’s anatomy. During the operation, the robotic system provides real-time data and feedback, ensuring optimal alignment and positioning of the implant components.
What are the benefits of robotic surgery for arthritis?
Compared to traditional techniques, robotic-assisted knee surgery offers several advantages for eligible patients:
- Improved implant positioning: Reducing wear and increasing implant longevity
- Smaller incisions: Leading to less soft tissue damage
- Reduced pain and blood loss: Aiding faster recovery
- Faster rehabilitation: Allowing patients to return to normal activities sooner
- Lower complication and revision rates: Particularly in knee replacement procedures
When is robotic knee surgery recommended for arthritis?
Robotic surgery is primarily used for:
- Partial knee replacement: In cases where arthritis affects only one compartment of the knee
- Total knee replacement: For patients with widespread damage across the joint
It's especially suitable for patients with complex anatomy or those seeking high-performance outcomes from their knee replacement.
Who's a candidate for robotic-assisted knee replacement?
Patients with moderate to severe knee arthritis who haven't responded to conservative treatments may be considered. Ideal candidates include those who:
- Experience persistent knee pain and stiffness
- Have difficulty walking, climbing stairs or standing for long periods
- Want a more accurate and potentially longer-lasting joint replacement
A consultation with an orthopaedic knee specialist is necessary to assess the joint and determine if robotic-assisted surgery is the best option.
