With remarkable success, surgeons are using the same technology that guides motorists through our streets to replace joints like knees and hips.
Developed in the UK, the system, called Orthopilot, allows surgeons to align artificial knee joints far more accurately than the could using conventional methods.
“It is really nothing more than a GPS system,” surgeon Derek Bickerstaff told Sky News.
“Medicine has now been dragged up to the technology we have today.
“It is a natural progression and can be applied to so many things.”
Jane Ford, 62, from Derbyshire has a total knee replacement for her right knee in June last year using the new technology.
