Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

After anterior cruciate ligament reconstruction (ACL-R), Single Hop for Distance (SHD) performance aids in decision-making, particularly for return-to-sport assessments. However, asymmetrical landing kinematics are common after ACL-R, even with symmetrical performances, and increase the risk of re-injury. To support clinical practice, several qualitative scales have been developed as valid and reliable tools for assessing landing quality. In 2022, Measson et al. adapted the Landing Error Scoring System for use during an SHD task (SHD-LESS scale) and demonstrated its reliability among healthy individuals.

The aim of this study is to test the validity of this scale after ACL-R by evaluating its ability to identify asymmetrical landing and characterize differences between the operated and uninjured limb. The second objective is to assess its association with knee muscle strength, functional status and psychological readiness.

Landing error assessment during a SHD task using the SHD-LESS scale

Intervention Type DIAGNOSTIC_TEST

Participants will perform a 2D-camera-recorded SHD task, with the SHD-LESS scored by two sports medicine physicians. Additional tests include isokinetic muscle testing, as well as functional and psychological status assessments, following standard clinical practice.
