Motivational Feedback Following Total or Unicompartmental Knee Arthroplasty
Sponsor: Odense University Hospital
Summary
The goal of this randomized controlled trial (RCT) nested in a prospective cohort study is to investigate whether physical activity (PA) following total knee arthroplasty (TKA) or unicompartmental knee arthroplasty (UKA) can be optimized by the use of an activity tracking device including motivational feedback in comparison with activity tracking without feedback. Furthermore, the project will investigate the predictive value of PA level prior to TKA/UKA for the length of stay, return to work, and quality of life. The main hypothese of the study are: RCT study: * Using an activity tracking device, including motivational feed-back on PA show a superior short-term effect on increased PA (Total counts; primary outcome measure), physical functioning, return to work, and quality of life in comparison with no motivational feed-back from the activity tracker, defined as 'care as usual', in TKA and UKA patients * Using an activity tracking device, including motivational feedback, will have a superior effect on step counts, activity types and pain compared to the standard care, in TKA and UKA patients Prospective cohort: * PA prior to TKA or UKA can work as a predictive measure for function and quality of life following surgery * PA prior to TKA or UKA can work as a predictive measure for the length of hospital stay and return to work Patients will be randomized to activity tracking and motivational feed-back by gamification for patient self-mobilization (Intervention-group) or 'care-as-usual' including activity tracking without motivational feed-back (Control-group). Patients not eligible and/or willing to participate in the RCT study, will be offered to participate in a prospective non-interventional cohort study.

Interventions
SENS Motion + Motivational Feedback
To weeks prior to surgery and in a 12-week period following discharge after TKA/UKA patients will be equipped with a discrete patch and built-in accelerometer (SENS Motion, Denmark, Copenhagen) attached on the thigh of the leg not undergoing surgery. Following discharge after TKA/UKA patients randomized to the intervention-group will receive the app ("SENS motion"). On their provided app, patients will be able to choose between two tabs. Tab 1 will allow patients to view predefined goals, all of which are locations in a self-selected city. The sensor will measure the physical activity and daily rhythm of the patient, and accelerometer counts will be converted into daily steps, which will be visible to the patients. In Tab 2, patients will be able to see graphical representations of their daily activity as well as their history during the period in which they have worn the accelerometer. The graphical representations include: Daily steps, physical active minutes, and type of activity.
