Zimmer 'smart knee' gets FDA nod as ortho rivalry with Stryker heats up

FDA on Monday granted De Novo marketing authorization to Zimmer Biomet and Canary Medical's "smart knee" implant for total knee replacement. The device, called Persona IQ, combines Zimmer's Persona knee with Canary's implantable sensor technology to measure a patient's range of motion, step count, walking speed and other metrics.
