About this study
The device "Patello" was designed to passively mobilize the Patella in cranial-caudal direction. Its application field lays in the rehabilitation of any knee pathology where knee range of motion may be restricted due to the Patella mobility.
Read the detailed description
The effectiveness of the device Patello has not been tested so far. This clinical study aims to assess and proof the effectiveness of this device. The aim is to objectify the movement of the Patella induced by the device Patello in cranial / caudal direction. As outcome parameter serve ultrasound measurements of a bony reference point of the femur and the Patella and its displacement / distance after mobilization.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
PatelloDevice
The Patello is a new intervention device which mobilizes the Patella passively and continuously in cranial-caudal direction to increase Patella mobility.
| Study group | Role | What they receive |
|---|---|---|
| Patello | Experimental | The participants' right knee was placed inside the patello device, a total of 50 repetitions, with a constant mobilisation speed, was conducted and the degree of translation was assessed after 1, 10, 20, 30 and 50 repetitions. Receives: Device: Patello |
What is being measured
The primary outcome is the main question the study is designed to answer.
Patellofemoral Translation
Patellar cranial-caudal translation (in centimeters) is assessed repeatedly within a single passive continuous mobilization session. A total of 50 repetitions are performed at a constant mobilization speed. Ultrasound video sequences are recorded, and patellar translation is analyzed immediately after 1, 10, 20, 30, and 50 repetitions during the same session.
Measured: Assessed after 1, 10, 20, 30 and 50 mobilization repetitions during a single continous passieve patellar moblizitaion session of 50 repetitions (total duration approximately 5-10 minutes)

Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 2 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 2 Dec 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Patellofemoral Translation (time frame: Assessed after 1, 10, 20, 30 and 50 mobilization repetitions during a single continous passieve patellar moblizitaion session of 50 repetitions (total duration approximately 5-10 minutes)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03512652, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Dec 2025.
