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 Results may not be published yet.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

Summary

Researchers are testing whether giving the steroid dexamethasone during total knee replacement helps with pain, nausea, and recovery, and whether it matters if the drug goes into a vein or is injected around the knee joint. The trial enrolls 159 adults with knee osteoarthritis having their first knee replacement at one hospital. Participants are randomly assigned to receive intravenous dexamethasone, periarticular dexamethasone, or standard care without steroids, and researchers track pain scores, knee function, nausea, hospital stay length, and complications.

What this could mean

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

Active substance
dexamethasone, a steroid given either into a vein or injected around the knee joint
What this could lead to
If one method works better, it could give surgeons a clearer way to reduce pain and nausea after knee replacement, possibly helping patients recover with less discomfort.
What could go wrong
This is a single-center study of 159 people, so results may not apply everywhere. Steroids can raise blood sugar and slightly increase infection risk, and the differences between the three approaches may turn out to be small.
