Patient Reported Outcome Measures (PROMs) in Rehabilitation With or Without the Possible Use of a Mobile Application After Primary Knee or Hip Arthroplasty
Patient Reported Outcome Measures (PROMs) in Rehabilitation With or Without the Possible Use of a Mobile Application After Primary Knee or Hip Arthroplasty
Rehabilitation after primary knee or hip arthroplasty traditionally includes performing
 exercises with a physiotherapist. For patients who can work well with a computer, tablet or
 smartphone, it is now possible to use a mobile application (e.g. moveUp) to carry out a large
 part of the exercises more independently. This is done with online guidance by a
 physiotherapist via a mobile application that is CE marked in Europe.

 This study will investigate whether the effect of the mobile application on knee or hip
 rehabilitation and quality of life is equal to that of standard care (i.e. performing
 exercises with a physiotherapist).
Via the moveUP Coach App, patients receive personalized rehabilitation for knee or hip
 replacement, both before and after surgery. This mobile application is on the market, meets
 the legal requirements in Europe and has been provisionally remunerated under an agreement
 (convention) between the mandatory health insurance (NIHDI) and the hospital that participate
 in this study.

 Eligible patients will be randomized to one of the three treatment options of the study:

 1. The "usual care group" will not be informed about the mobile application and will
 perform exercises as per standard of care with a physiotherapist during face to face
 visits.

 2. The group "possibility to use the mobile application with a predefined number of
 physiotherapy sessions" will receive all necessary information on the mobile application
 and can still decide whether or not to use the mobile application. A predefined number
 of traditional physiotherapy sessions is combined with the use of the mobile app in this
 group.

 3. The group "possibility to use the mobile application without a predetermined number of
 physiotherapy sessions" will receive all necessary information on the mobile application
 and can still decide whether or not to use the mobile application. No predefined number
 of traditional physiotherapy sessions are required.

 The patient will be asked to complete 3 questionnaires (KOOS-JR, HOOS-JR and EQ5D-5L) at
 baseline, 6 weeks and 6 months after arthroplasty. These patient reported outcomes will give
 an indication on the rehabilitation outcome and quality of life compared in the 3 groups.

 Additionally, a health economic evaluation is foreseen by the Federal Knowledge Center for
 Healthcare (KCE) in cooperation with the sponsor UZ Ghent. In this way the results can be
 helpful in getting a more definitive refund for the mobile application in Belgium.
Eligibility criteria:

 1. The patient is aged 18 years or older, has a Belgian National Number, is insured by a
 Belgian sickness fund, and is not staying in a nursing home or long term
 rehabilitation centre.

 2. The patient has sufficient knowledge of Dutch, French, German or English.

 3. The patient has a planned date within the next 8 weeks for a primary unilateral
 unicompartmental knee arthroplasty (UKA); a bicompartmental knee arthroplasty, (BKA),
 consisting of either two UKA or a UKA and a patellar replacement; or a total knee
 arthroplasty (TKA) or a total hip arthroplasty (THA).

 4. The patient is not planned to have a peri-operative procedure (e.g. intra-articular
 catheter) or postoperative procedure that is expected to significantly impact the
 rehabilitation in and out of hospital.

 5. In the 6 months after arthroplasty the patient is not planned to have surgery that may
 impact the arthroplasty rehabilitation.

 6. The patient is not suffering from a medical condition (e.g. Parkinson, multiple
 sclerosis, cerebrovascular accident) that is expected to significantly impact the
 rehabilitation or that constitutes a contra-indication for the use of the mobile
 application.

 7. The patient confirms to have easy and daily access to the internet, a mobile phone, a
 personal email address and a computer, tablet or smartphone, now and over the next 8
 months.

 8. The patient does not upfront exclude the possibility whereby part of the
 rehabilitation is performed without a physical therapist physically being present.

 9. The patient is willing to complete online the patient reported outcomes and is aware
 that if he/she fails in this computer literacy test (performed before randomization)
 he/she will not be randomized and hence not included in the study. He/she will receive
 usual rehabilitation care.
