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 Results may not be published yet.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 trial tests whether adding platelet-rich plasma (PRP) — made from a person's own blood — to a standard hyaluronic acid injection improves knee pain and function in people with knee osteoarthritis. Half of the 50 participants receive the combined injection, while the other half get hyaluronic acid alone. The study tracks pain, mobility, and quality of life over 18 months to see if the combination offers extra benefit.

What this could mean

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

Active substance
A single injection combining hyaluronic acid with the participant's own platelet-rich plasma (PRP), compared with hyaluronic acid alone.
What this could lead to
If the combination works, it could offer a more effective injection therapy for knee osteoarthritis, potentially reducing pain and improving function without surgery.
What could go wrong
This is a small, early-stage study (50 people), so results may not apply broadly. The added benefit of PRP over hyaluronic acid alone is unproven, and injections carry risks like pain or infection.
