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.

Stopped early This study
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.

Summary

This study aimed to see if using a tourniquet less during ACL reconstruction surgery helps patients recover quadriceps muscle function faster and with less pain. Only 1 person was enrolled before the trial was terminated, so no meaningful results were obtained. The study was designed to compare limited tourniquet use versus standard use in adults having ACL surgery with a patellar tendon graft.

What this could mean

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

What this could lead to
If successful, this could show that using a tourniquet less during ACL surgery helps patients recover quadriceps strength faster and with less pain.
What could go wrong
The trial was terminated early with only 1 participant, so no reliable conclusions can be drawn. Results may not apply to all ACL patients.
