Knee and hip replacements at Nuffield Health Exeter Hospital can now be performed using robotic arm technology.

How does robotic arm assisted surgery work?

Before surgery

In the weeks before your operation, our robotic arm, or Boris as we like to call him, processes the information taken from a 3D CT scan of your body. Your consultant then plans the operation to within fractions of a millimetre with the help of Boris.

During surgery

Your consultant is always in control during the operation. Boris allows the consultant to perform the joint replacement with pinpoint accuracy. The consultant uses Boris's arm as an extension of his or herself, guiding surgical tools to the correct position.


Higher accuracy means the replacement fits as well as it possibly can and ensures the joint functions as normally as possible after surgery.

It's been shown to result in a shorter hospital stay, quicker recovery and higher satisfaction. There's also strong evidence of decreased pain and fewer complications following surgery.

Who is robotic arm surgery suitable for?

Robotic arm surgery may not be appropriate for all patients. Your consultant will advise you on the best treatments for your condition.
