Robotic-Assisted Surgery
Robotic-assisted surgery uses a computer-controlled robotic system to augment the surgeon's precision during joint replacement and other complex procedures. In orthopaedics, the robotic arm (such as the MAKO system) guides the surgeon to place implants with sub-millimetre accuracy based on a pre-operative 3D plan. The robot does not operate independently — the surgeon is in full control at all times. Studies show robotic-assisted joint replacement achieves more accurate implant positioning, more natural limb alignment, and potentially longer implant survival compared with conventional techniques.
How Robotic-Assisted Surgery is performed
- 1
Pre-operative CT scan of the joint is used to create a personalised 3D plan.
- 2
In the operating theatre, the robotic system is registered to the patient's anatomy.
- 3
The surgeon makes the incision and proceeds with the operation.
- 4
The robotic arm provides real-time guidance and boundary control during bone preparation.
- 5
Implants are placed exactly as planned; the robot provides feedback if the surgeon deviates.
- 6
The wound is closed in the usual manner.
Benefits of Robotic-Assisted Surgery
- ✓Sub-millimetre accuracy in implant placement
- ✓Personalised 3D pre-operative plan for each patient's unique anatomy
- ✓Less bone is removed — only what is needed
- ✓More natural joint kinematics and alignment
- ✓Potential for faster rehabilitation and longer implant survival
Preparing for Robotic-Assisted Surgery
- Pre-operative CT scan (in addition to standard X-rays) is required for robotic planning.
- All other preparation is the same as for conventional knee or hip replacement.
Risks and side effects of Robotic-Assisted Surgery
- Same risks as conventional joint replacement (infection, DVT, stiffness)
- Slightly longer operating time in some cases
- The benefits over conventional surgery are still being confirmed by long-term studies
Your surgeon will discuss all risks with you before the procedure and take appropriate precautions to minimise them.
Recovery after Robotic-Assisted Surgery
- Post-operative care and physiotherapy are the same as for conventional joint replacement.
- Many surgeons report that patients progress faster with robotic-assisted surgery, though protocols are similar.
Robotic-Assisted Surgery FAQs
Does the robot perform the surgery on its own?
No. The robotic arm is a precision tool that assists the surgeon — it does not operate independently. The surgeon is in complete control at all times.
Is robotic surgery available for all joints?
Robotic-assisted systems are currently most established for knee and hip replacement. Research into shoulder and ankle replacement with robotic assistance is ongoing.
