What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Biomechanical analysisProcedure or surgery
Biomechanical assessment is performed using a set of sensors (Qualisys Sports Marker Set - functional assessment, already in use at the Clinique du Sport) as well as 3D optoelectronic cameras and force and pressure platforms. These sensors are placed at various points on both lower limbs (hip, knee, ankle) and provide data in different planes (sagittal, frontal, transverse), as well as a comparison of both sides.

What is being measured
The primary outcome is the main question the study is designed to answer.
Angular measurements by biomechanical sensors
Angle measurements at hip, pelvis, knee and ankle in the three planes of space (sagittal, frontal and transverse), measured by biomechanical sensors.
Measured: 6 months after surgery
Vertical forces measured by biomechanical sensors
Vertical forces, push and landing, will be evaluated for each phase of the movements. Biomechanical specific sensors will be used to measure these data
Measured: 6 months after surgery

Who may be eligible to take part?
The sponsor lists 4 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 9 Jul 2026. 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 France. 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.

How can a doctor refer a patient or contact the research team?
Contact Pierre Laboudie, MD (+33671270463, pierre.laboudie@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Angular measurements by biomechanical sensors (time frame: 6 months after surgery). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 9 Jul 2026.
