Validity of the SHD-LESS Scale After ACL Reconstruction

Recruiting

• Conditions: ACL Reconstruction; ACL Injury

• Registration Number: NCT06829849
• Lead Sponsor: University Hospital, Caen

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.

Primary Outcome Measures

Name	Time	Method
Single Hop for Distance, Landing Error Scoring System (SHD-LESS) scale	One measurement during the visit at 6 to 12 months after surgery	The LESS (Landing Error Scoring System) scale is a 13-item tool used to assess landing technique during a hop task.

Secondary Outcome Measures

Name	Time	Method
Strength	One measurement during the visit at 6 to 12 months after surgery	Measurement of knee extensors and flexors peak strength (in newton.meter, Nm) on isokinetic dynamometer
ACL-RSI questionnaire (Anterior Cruciate Ligament-Return to Sport after Injury)	One measurement during the visit at 6 to 12 months after surgery	The ACL-RSI measures the patient's understanding of his knee. It comprises 12 questions with a score of 1 to 10 for each
International Knee Documentation Committee (IKDC) score	One measurement during the visit at 6 to 12 months after surgery	Knee level of function based on patient-reported measures from symptoms to daily activities. The IKDC score includes sections on knee symptoms (7 items), function (2 items), and sports activities (2 items), with scores ranging from 0 (lowest function, highest symptoms) to 100 (highest function, lowest symptoms).
