REHAPT: Evaluation of Safety and Efficacy of ReHub in Patients Who Underwent Primary Total Knee Arthroplasty
Study Details
Study Description
Brief Summary
This is a randomized, non-blinded, parallel assignment, clinical trial for the evaluation of safety and efficacy of ReHub, a telerehabilitation system made up of a cloud platform and an exercise kit with smart sensors, for performing rehabilitation exercises after a primary Total Knee Arthroplasty.
Primary TKA patients are allocated randomly to the control arm or the experimental arm with a 1:1 ratio. Both arms follow the usual rapid recovery protocol for TKA surgeries at Hospital Clínic de Barcelona, which includes discharge after 2-3 days from the surgery, the prescription of a daily plan of 5 exercises for autonomous rehabilitation and domiciliary visits by a physiotherapist starting approximately 2 weeks after the surgery. The experimental arm participants use ReHub to do their exercises instead of working independently and physiotherapists monitor their performance and adherence remotely.
Outcomes assessment is performed at hospital discharge (baseline), at stitch removal (2 weeks after baseline) and 2 weeks after stitch removal (4 weeks after baseline).

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: Conventional Rehabilitation Group Participants follow the usual fast-track protocol used at Hospital Clínic de Barcelona for Total Knee Arthroplasty and perform a daily 5-exercise plan autonomously. |
Other: Rapid Recovery Rehabilitation Programme
Usual intervention at Hospital Clínic de Barcelona for post-operative rehabilitation of TKA patients. Participants, already at home after hospital discharge, must perform 5 different exercises 4 times a day (twice in the morning, twice in the afternoon).
Participants are also encouraged to walk and stretch their legs. Domiciliary visits by a physiotherapist start at approximately 2 weeks after the surgery to help participants do the exercises.

| Experimental: ReHub Group Participants follow the usual fast-track protocol used at Hospital Clínic de Barcelona for Total Knee Arthroplasty but use the telerehabilitation platform ReHub to do the exercises in their rehabilitation plan at home and to have their progress monitored. |
Other: Rapid Recovery Rehabilitation Programme
Usual intervention at Hospital Clínic de Barcelona for post-operative rehabilitation of TKA patients. Participants, already at home after hospital discharge, must perform 5 different exercises 4 times a day (twice in the morning, twice in the afternoon).
Participants are also encouraged to walk and stretch their legs. Domiciliary visits by a physiotherapist start at approximately 2 weeks after the surgery to help participants do the exercises.
Device: ReHub
Participants use a telerehabilitation platform, ReHub, as a guide to perform the TKA rehabilitation exercises of the Rapid Recovery Rehabilitation Programme intervention.
The exercise plan in ReHub is carried out by a site physiotherapist on the first day after discharge by using ReHub to acquire the participant's movement pattern with a wearable inertial sensor that transmits data to the platform.
The wearable inertial sensor participants must wear tracks movement while they do the TKA rehabilitation exercises. Movement is analysed and feedback is given in real time. At the end of each exercise, participants can select if they have felt pain in a scale from 1 to 10. A physiotherapist monitors the participants' progress remotely.

Outcome Measures
Primary Outcome Measures
- Change in Active Knee Range of Motion (º) [Baseline, 2 weeks and 4 weeks after discharge]
Range of motion of the replaced knee without the aid of the outcomes assessor will be measured with a conventional goniometer.
Secondary Outcome Measures
- Change in the Timed Up-and-Go test score (s) [Baseline, 2 weeks and 4 weeks after discharge]
The TUG test outcome is the time that a person takes to rise from a chair, walk three meters, turn around, walk back to the chair, and sit down.
- Change in Self-Reported Pain Level: Visual Analogue Scale [Baseline, 2 weeks and 4 weeks after discharge]
The pain level will be reported by the participant with a Visual Analogue Scale from 0 to 10, with 0 being the absence of pain and 10 being the worst pain imaginable.
- Change in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score [Baseline, 2 weeks and 4 weeks after discharge]
Scores for the WOMAC questionnaire range from 0 to 96, with 0 being the best state and 96 the worst state.
- Change in EuroQol-5D-5L (EQ-5D-5L) score [Baseline, 2 weeks and 4 weeks after discharge]
Scores for the EQ-5D-5L questionnaire are 5-digit numbers, each one representing a different aspect of quality of life. Digits can range from 1 to 5. 11111 is considered the ideal state and 55555 the worst state. 9 is used for absent or non-valid answers. The questionnaire also includes a Visual Analogue Scale for indicating perceived self's health state in a scale from 0 (worst state) to 100 (best state).
- Change in Quadriceps Strength (kg) [Baseline, 2 weeks and 4 weeks after discharge]
Strength of the quadriceps in the intervened leg will be measured with a dynamometer.
- Change in Hamstring Strength (kg) [Baseline, 2 weeks and 4 weeks after discharge]
Strength of the hamstring muscles in the intervened leg will be measured with a dynamometer.
- Satisfaction with ReHub: System Usability Scale [4 weeks after discharge]
Measured with the score from the System Usability Scale questionnaire, which can range from 0 (worst result) to 100 (best result). Only for participants in the experimental arm.
- Change in Passive Knee Range of Motion (º) [Baseline, 2 weeks and 4 weeks after discharge]
Range of motion of the replaced knee with the aid of the outcomes assessor will be measured with a conventional goniometer.
