# Validity of the SHD-LESS Scale After ACL Reconstruction

**Official Title:** Validity of the SHD-LESS Scale in Detecting Landing Asymmetry and Its Association With Functional Status After ACL Reconstruction.

**NCT ID:** [NCT06829849](https://clinicaltrials.gov/study/NCT06829849)

## Key Facts

- **Status:** COMPLETED
- **Study Type:** OBSERVATIONAL
- **Target Enrollment:** 60
- **Lead Sponsor:** University Hospital, Caen
- **Conditions:** ACL Reconstruction, ACL Injury
- **Start Date:** 2024-03-01
- **Completion Date:** 2025-11-15
- **CT.gov Last Update:** 2026-04-01

## 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.

## Eligibility

- **Minimum age:** 18 Years
- **Maximum age:** 40 Years
- **Sex:** ALL
- **Healthy Volunteers:** No

```
Inclusion Criteria:

* Patients aged 18-40, who have undergone a first ACL reconstruction more than 6 months ago and are being followed in a sports medicine care pathway
* Affiliated with a health insurance plan
* Information form: Non-objection to the use of data for research purposes

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
```

## Arms

- **ACL reconstruction group** — All sports patients who had a muscle evaluation at 6 to 12 months after ACLR since March 2024

## 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.

## Primary Outcomes

- **Single Hop for Distance, Landing Error Scoring System (SHD-LESS) scale** _(time frame: 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 Outcomes

- **Strength** _(time frame: One measurement during the visit at 6 to 12 months after surgery)_
- **ACL-RSI questionnaire (Anterior Cruciate Ligament-Return to Sport after Injury)** _(time frame: One measurement during the visit at 6 to 12 months after surgery)_
- **International Knee Documentation Committee (IKDC) score** _(time frame: One measurement during the visit at 6 to 12 months after surgery)_
