A Cambridge University vet has carried out pioneering surgery to repair a dog's knee - with the help of a 3D printer.

Professor Matthew Allen used a printed version of the knee to help design a bespoke tool, which he also 3D printed, to guide him when cutting away damaged bone from the joint.

3D printing replicas from CT scans of bones is not new but in this case they then used it to help design a surgical tool.

They believe it's the first time a 3D printer has been used to create a surgical guide for a partial knee replacement.

Printing bones can also help them to prepare for the surgery.
