Evaluation of Safety and Efficacy of ReHub in Patients Who Underwent Primary Total Knee Arthroplasty

Not Applicable
Completed
Conditions
Knee Osteoarthritis

Device: ReHub
Registration Number
NCT04155957
Lead Sponsor
Bio-Sensing Solutions S.L. (DyCare)
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).

Primary Outcome Measures
NameTimeMethod
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
NameTimeMethod
Change in EuroQol-5D-5L (EQ-5D-5L) scoreBaseline, 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 Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scoreBaseline, 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 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 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.

Change in Self-Reported Pain Level: Visual Analogue ScaleBaseline, 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 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.

Satisfaction with ReHub: System Usability Scale4 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.
