ACL Injury, ACL Reconstruction
Conditions
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.
Interventions
DIAGNOSTIC_TESTLanding error assessment during a SHD task using the SHD-LESS scale
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.

Exclusion criteria
* Previous ligament surgery of the lower limbs prior to ACL reconstruction * Complex ligament injury (lateral ligaments, posterior cruciate ligament) * Recent muscle injuries * History of injury to the uninjured knee * Pregnant woman * Inability to perform a muscular assessment * Postoperative complications (deep vein thrombosis, sepsis, stiffness/arthrofibrosis) * Neurological history with residual effects or taking medication that affects balance/coordination
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame | Description |
|---|---|---|
| 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). |
