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 Results may not be published yet.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.

Summary

This trial compared two types of hamstring tendon grafts for repairing a torn anterior cruciate ligament (ACL) in the knee. 42 patients received either a graft using only the semitendinosus tendon or a graft using both the semitendinosus and gracilis tendons. The main goal was to see if using just one tendon affected leg strength differently than using two.

What this could mean

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

Active substance
surgical procedure (quadrupled semitendinosus graft or combined semitendinosus-gracilis graft)
What this could lead to
If successful, this could show that using only the semitendinosus tendon preserves hamstring strength just as well as using both tendons, potentially reducing surgical side effects.
What could go wrong
This is a small, completed trial with only 42 participants, so results may not apply to everyone. The study focuses on strength and re-rupture rates, but long-term outcomes are not yet clear.
