A cat has received two bionic legs in a world-first operation set to transform treatment for human amputees.

Oscar, whose paws were cut off by a combine harvester, can run and leap thanks to the mechanical implants.

They were drilled into his ankle then treated with a substance that allows bone and skin to grow around them.

Fake paws were then fitted on "see-saw" joints at the end of the prosthetics, giving full movement.

Four months later he bore weight equally. Now he runs.

Fitzpatrick said the techniques he used are "set to transform the future" of orthopedics.
