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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 is testing whether artificial intelligence can accurately analyze knee MRI images. Researchers will review thousands of existing knee scans to see if AI can identify and measure knee structures and abnormalities as well as trained experts. The goal is to make knee imaging evaluation more objective and consistent, potentially improving how knee conditions are diagnosed and monitored.

What this could mean

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

Active substance
Artificial intelligence-based image analysis of knee MRI scans
What this could lead to
If successful, this could lead to more objective and consistent AI tools for reading knee MRIs, potentially aiding diagnosis and treatment planning.
What could go wrong
This is an observational study using existing scans, so it cannot prove AI improves patient outcomes. The AI's performance may not generalize to other hospitals or MRI machines.
