Gosford Private Hospital, the Mater Hospital in Brisbane and the Mater Private are three of the expected five hospitals that are involved in a CSIRO-led trial of a smartphone app that delivers pre-surgery preparation and post-surgery rehabilitation for patients undergoing total knee replacements.

The trial, which kicked off last November and aims to recruit 300 patients to test the technology before launching it on the market, is being led by researchers from CSIRO's Australian e-Health Research Centre, Health and Biosecurity and Data61.
