Knee arthritis can significantly affect mobility, comfort, and daily activities. When non-operative treatments are no longer providing relief, knee replacement surgery may be recommended. Modern surgical tools, including robotic-assisted technology, are increasingly being used by orthopaedic surgeons to support accuracy and patient-specific planning.
This article explains what robotic-assisted knee replacement involves, how it works, and what patients can expect when discussing this option with Dr George Awwad.
What is robotic-assisted knee replacement surgery?
Robotic-assisted knee replacement is a technique that uses advanced computer guidance to help the surgeon plan and perform joint replacement with a high degree of accuracy.
It is important to understand that:
- The surgeon remains fully in control at all times
- The robotic system does not perform the surgery on its own
- The technology acts as a precision tool to support the surgeon’s decisions
Robotic systems may assist with planning implant size, alignment, and positioning based on each patient’s individual anatomy.
How robotic technology supports personalised planning
Before surgery, patients typically undergo detailed imaging such as X-rays or a CT scan. These images are used to create a digital map of the knee, which helps the surgeon understand the exact shape, wear pattern, and alignment of the joint.
This allows the surgeon to:
- Analyse joint deformities or arthritis patterns
- Plan implant size and positioning
- Tailor the surgical approach to the patient’s anatomy
- Make adjustments digitally before entering the operating theatre
Dr Awwad uses robotic-assisted planning tools where appropriate to support accuracy and surgical decision-making.
What happens during robotic-assisted knee replacement?
During the procedure, the robotic system provides real-time feedback to the surgeon. This may include information about bone angles, ligament tension, and joint alignment.
The technology can help:
- Guide the positioning of surgical instruments
- Assist the surgeon in placing the implants in the planned orientation
- Support balance between the soft tissues around the knee
All critical decisions are made by the surgeon, with the robotic system acting as a supportive tool to help achieve the planned alignment.
Potential benefits of robotic-assisted knee replacement
While outcomes vary between individuals, robotic-assisted techniques may offer several potential advantages:
- More personalised implant positioning based on your anatomy
- Improved planning through digital mapping before surgery
- Consistent alignment accuracy supported by computer guidance
- Support in managing complex deformities or unusual joint shapes
It is important to note that robotic assistance is just one part of a successful knee replacement. Surgeon expertise, medical management, physiotherapy, and patient participation in rehabilitation remain equally important.
Is robotic-assisted knee replacement suitable for everyone?
Not all patients require robotic-assisted surgery.
Dr Awwad will consider a number of factors including:
- The severity and pattern of arthritis
- Your overall health and activity level
- Previous injuries or surgeries
- Whether robotic planning will meaningfully assist your case
During your consultation, you can discuss whether robotic-assisted planning is appropriate for your individual condition.
Recovery and what to expect
Recovery after robotic-assisted knee replacement is similar to traditional knee replacement. Key elements include:
- Early mobilisation with physiotherapy
- Pain management
- Wound care
- Regular follow-up appointments
- Gradual return to daily activities
Dr Awwad will outline a personalised recovery plan and monitor your progress through follow-up assessments.
A balanced and informed decision
Robotic-assisted technology offers additional planning and guidance during surgery, but it is not the only factor that determines a successful outcome.
A well-informed decision is based on understanding:
- Your diagnosis
- All available treatment options
- The surgeon’s recommendations
- Realistic expectations about recovery
Dr Awwad ensures that each patient receives a personalised assessment and clear explanation of whether robotic-assisted knee replacement is suitable for their situation.
