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 This study
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 Results may not be published yet.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

Summary

This study will compare two surgical techniques for children who have repeated kneecap dislocations. One surgery repairs only the main ligament (MPFL), while the other also repairs a secondary ligament (MPTL). The goal is to see which approach better prevents future dislocations and improves knee function. Twenty-two children under 18 will be followed for at least two years.

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 (MPFL reconstruction alone or combined with MPTL reconstruction)
What this could lead to
If successful, this study could show that adding a second ligament reconstruction reduces the chance of the kneecap dislocating again and improves knee function in children.
What could go wrong
This is a very small, early study with only 22 children, and it hasn't started yet. Surgery always carries risks like infection or stiffness, and the best approach is still debated.
