What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tested a new scale called SHD-LESS to see if it can detect landing asymmetry in people who had ACL reconstruction surgery. Sixty participants performed a single hop for distance while being recorded on video, and two doctors scored their landing technique. The goal is to improve return-to-sport decisions and reduce the chance of re-injury.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Landing error assessment using the SHD-LESS scale (diagnostic test)
What this could lead to
If successful, this scale could help doctors better identify who is ready to safely return to sports after ACL surgery, potentially reducing re-injury risk.
What could go wrong
This is a small, completed study with only 60 participants, so results may not apply to everyone. The scale is new and needs more testing before routine use.
