What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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.

Summary

This study tests whether a 4-week exercise program delivered through a smartphone app works as well as supervised sessions with a physical therapist before anterior cruciate ligament (ACL) knee surgery. Sixty-six adults aged 18 to 45 with an ACL tear will be split into three groups: app-based exercises, therapist-supervised exercises, or no specific exercise plan. Researchers will measure knee strength, range of motion, and patient-reported function before and after surgery to see which approach leads to better recovery.

What this could mean

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

Active substance
exercise program (via smartphone app or supervised by a physiotherapist)
What this could lead to
If it works, this could show that a simple phone app is as effective as in-person physical therapy for preparing patients for ACL surgery, making pre-surgery exercise more accessible.
What could go wrong
This is a small, early-stage trial with only 66 participants, so results may not apply to everyone. The app may not match the benefits of personalized supervision, and some patients might not follow the program correctly.
