Biomechanical analysis

Procedure: Biomechanical analysis; 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 the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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.	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	6 months after surgery
