Brief Summary

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.

Conditions

ACL Reconstruction; ACL Injury

Outcome Measures

Primary Outcomes (1)

• Single Hop for Distance, Landing Error Scoring System (SHD-LESS) scale

  The LESS (Landing Error Scoring System) scale is a 13-item tool used to assess landing technique during a hop task.

  One measurement during the visit at 6 to 12 months after surgery

Secondary Outcomes (3)

• Strength

  One measurement during the visit at 6 to 12 months after surgery

• ACL-RSI questionnaire (Anterior Cruciate Ligament-Return to Sport after Injury)

  One measurement during the visit at 6 to 12 months after surgery

• International Knee Documentation Committee (IKDC) score

  One measurement during the visit at 6 to 12 months after surgery

Study Arms (1)

ACL reconstruction group

All sports patients who had a muscle evaluation at 6 to 12 months after ACLR since March 2024

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

Interventions

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

ACL reconstruction group
