Can a smartphone-based care platform rival traditional care models?


Study finds evidence of similar early outcomes to traditional care models in primary knee arthroplasty


This multi-centre prospective randomised control trial – presented as an e-poster at the AAHKS November 2020 – evaluated the use of the mymobility® smartphone-based care platform for primary total and partial knee replacement. 1

The control group consisting of 224 patients received the usual standard of care, which normally involved some formal physical therapy. The 192 patients randomised to the treatment group were given an Apple Watch and the mymobility smartphone application. There were no significant between-group differences in age, BMI or gender. 1

Early outcomes assessed were: 

  • 90-day knee range of motion
  • KOOS Jr scores
  • 30-day single leg stance (SLS) time
  • Timed up and Go (TUG) time 
  • Necessity for manipulation under anaesthesia (MUA). 

There were no statistically significant between group differences in any of the early outcome measures assessed. 1 

The authors concluded that: “The use of the mymobility care platform demonstrated similar early outcomes to traditional care models, while providing communication and insights into patient engagement with the care plan. There was no significant difference in 90-day range of motion or need for MUA.”1
