Clinical Trial Summary

This study will investigate whether the recovery of muscle function of total knee arthroplasty is accelerated with the use of the gekoTM device along with its effect on reducing symptoms such as oedema and inhibition of the muscle function.


Description:

This study will investigate total knee arthroplasty patients: - One group gets standard of care (i.e. performing exercises & guidance by a physiotherapist via a CE-marked mobile application, called moveUP) - Second group gets standard of care + GekoTM device (i.e. non-invasive neuromuscular electrostimulation applied at the peroneal nerve for 10 days after the operation date.) The primary objective of the study is to assess the post-operative effect of gekoTM on formation of oedema (measured by perometer). The effect of the gekoTM device on the muscle function & the overall recovery will be also investigated. To collect parameters, the patient will be asked to complete questionnaires, including the following patient reported outcomes (PROMs): Knee Injury and Osteoarthritis Outcome Score (KOOS), Knee Society Score (KSS), Euroqol Health questionnaire EQ5D, Forgotten Joint Score (FJS), Oxford Knee Score (OKS). The collection of the PROMs will give an indication on outcome and overal recovery in the 2 groups.

Study Design


Intervention

Device:
gekoTM
The gekoTM device is a small, transcutaneous nerve stimulator that is placed non-invasively on the skin, whereby the surface electrodes will be attached close to the peroneal nerve. Activation of the peroneal nerve causes contraction of the calf muscle pump, which will increase blood circulation that corresponds to 60% of walking. The increased blood circulation reduces the pressure difference between capillaries and the surrounding tissue and transfers the tissue fluid back into the veins and lymph fibers

Outcome

Type Measure Description Time frame Safety issue
Primary The primary objective of the study is to assess the post-operative effect of gekoTM on formation of oedema following Total Knee Arthroplasty (TKA) This is measured by the use of a perometer. For each patient, change in limb volume shall be calculated as a percentage of original limb volume.
Shapiro-Wilk test shall be used to test whether there is a significant (p<0.05) departure from normal distribution in either group.
until end of rehabilitation (+- 3 months after TKA operation)
Secondary Incidence of Adverse Events Any untoward medical occurrence, unintended disease or injury or any untoward clinical signs, including an abnormal laboratory finding, in subjects, users or other persons, in the context of a clinical investigation, whether or not related to the investigational device.
(MDR Article 2(57)). The total number adverse events and the total number (%) of patients that had at least 1 adverse event will be stated.
until end of rehabilitation (+- 3 months after TKA operation)
Secondary Incidence of Device Deficiency Any inadequacy in the identity, quality, durability, reliability, safety or performance of an investigational device, including malfunction, use errors or inadequacy in information supplied by the manufacturer.(MDR Article 2(59)) during 10 days after TKA operation
Secondary Oedema measurements - subjective slider Temperature/swelling: Identical subjective slider as daily evaluated by the patient itself presenting the result as a Visual Analog Scale score, minimum 0 (no swelling) maximum 100 (Very swollen) until end of rehabilitation (+- 3 months after TKA operation)
Secondary Oedema measurements - photographic evaluation picture of both knees (moveUP): Patients need to make a picture of both knees, using the photo camera on their smartphone to see the swelling of the operated leg compared to the non-operated leg and to evaluate the swelling of the operated leg.
This blind assessment of pictures is performed by a physical therapist.
until end of rehabilitation (+- 3 months after TKA operation)
Secondary Patient Reported Outcome Measures (PROM's) The PROMS's measured:
- KOOS: Knee injury and Osteoarthritis Outcome Score for Joint Replacement. 42 items on 5-point Likert scale (multiple choice), total score is on 100, lower scores being indicative of worse knee conditions and higher scores being indicative of better knee condition
2 weeks pre-operative until end of rehabilitation (+- 3 months after TKA operation)
Secondary Patient Reported Outcome Measures (PROM's) The PROMS's measured:
- KSS: Knee Satisfaction Score. Multiple choice scale. Total score on 100, lower scores being indicative of worse knee conditions and higher scores being indicative of better knee conditions.
2 weeks pre-operative until end of rehabilitation (+- 3 months after TKA operation)
Secondary Patient Reported Outcome Measures (PROM's) The PROMS's measured:
- EQ5-D: Euroqol Health questionnaire. 5 items on 5-point Likert scale (multiple choice). Total score on 100. Secondly there is also 1 visual analog scale (VAS). The VAS Score is scored separately with lower scores being indicative of worse health and higher scores being indicative of better health (generic questionnaire, not disease specific)
2 weeks pre-operative until end of rehabilitation (+- 3 months after TKA operation)
Secondary Patient Reported Outcome Measures (PROM's) The PROMS's measured:
- OKS: Oxford Knee Score. 12 items Multiple choice. a lower score can be indicative for bad function or pain after TKA
2 weeks pre-operative until end of rehabilitation (+- 3 months after TKA operation)
Secondary Patient Reported Outcome Measures (PROM's) The PROMS's measured:
- FJS: Forgotten Joint score. 12-item mutiple choice score. Total score on 100 (%), lower scores being indicative of worse knee conditions and higher scores being indicative of better knee conditions.
2 weeks pre-operative until end of rehabilitation (+- 3 months after TKA operation)
Secondary Pain level Visual analogue scale (VAS), a 0-100 scale with 100 score = the worst pain the patient can feel and 0 = the patient feels no pain 2 weeks pre-operative until end of rehabilitation (+- 3 months after TKA operation)
Secondary Number of days of Painkiller intake PK intake stop is defined as no PK consumption for 3 consecutive days with no new 3 day-period of PK intake. 2 weeks pre-operative until end of rehabilitation (+- 3 months after TKA operation)
Secondary Dosage Painkiller intake 2 weeks pre-operative until end of rehabilitation (+- 3 months after TKA operation)
Secondary Number of days of NSAID intake NSAID intake stop is defined as no NSAID consumption for 3 consecutive days with no new 3 day-period of NSAID intake. 2 weeks pre-operative until end of rehabilitation (+- 3 months after TKA operation)
Secondary Dosage NSAID intake 2 weeks pre-operative until end of rehabilitation (+- 3 months after TKA operation)
Secondary Sleep duration the wearable measures accelerations during 23h-8h and gives an assumption duration of sleep during the night. The assumption of amount of sleep is based on: very little registration (deep sleep), little movements (light sleep), a lot of movements (waking up). 2 weeks pre-operative until end of rehabilitation (+- 3 months after TKA operation)
Secondary Sleep quality the wearable measures accelerations during 23h-8h and gives an assumption quality of sleep during the night. The assumption of amount of sleep is based on: very little registration (deep sleep), little movements (light sleep), a lot of movements (waking up). 2 weeks pre-operative until end of rehabilitation (+- 3 months after TKA operation)
Secondary Recovery of physical activity (PA) number of weeks until post-operative PA level is similar to pre-operative PA level, meaning there is no significant difference between mean post-operative step count (calculated on each post-operative week) and mean pre-operative step count (calculated on 7 days before surgery). 2 weeks pre-operative until end of rehabilitation (+- 3 months after TKA operation)
Secondary Number of days of crutches use until end of rehabilitation (+- 3 months after TKA operation)
Secondary Resume driving a car Number of days post-operative until end of rehabilitation (+- 3 months after TKA operation)
Secondary Overall Net Promotor Score (NPS) of the rehabilitation in general NPS = How likely would you recommend the rehabilitation to your friends or family?". Visual analogue scale (VAS), a 0-100 scale with 100 score = very likely and 0 = not likely 2 weeks pre-operative until end of rehabilitation (+- 3 months after TKA operation)
Secondary Satisfaction and feedback on the geko device (only for patients using the geko) Including:
Ease of use
Required level of stimulation (1 to 11)
Adherence to the geko use: daily collection of number of hours worn during the 10 days the geko device is used
during 10 days after TKA operation
