Robotic-assisted surgery planned around you

Robotic technology can support surgical planning and help guide parts of the procedure. Mr Unnithan remains responsible for the surgery and the decisions made throughout. The approach and equipment used will be explained during your consultation.

1

Your assessment

Your symptoms, examination and imaging help determine whether joint replacement is appropriate and whether robotic assistance may be suitable.

2

Your surgical plan

A personalised plan is developed for your joint replacement. Depending on the system used, this may include a CT scan and a three-dimensional model to support planning.

3

Your surgery

During the operation, the robotic system assists with aspects of the planned procedure under the surgeon’s control.

4

Your recovery

Your rehabilitation is tailored to your procedure and progress. You will receive guidance on movement, exercises and returning to everyday activities.
