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 Results may not be published yet.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

Summary

This study follows 5,000 adults receiving SERF hip prostheses for up to 15 years to see how long the implants last and how well patients function afterward. Researchers will track survival rates of the devices and measure improvements in mobility and pain using standard scores. The goal is to confirm the real-world safety and performance of these hip replacements.

What this could mean

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

Active substance
SERF hip prostheses (medical device)
What this could lead to
If successful, this study will confirm that SERF hip prostheses are safe and durable over the long term, helping doctors and patients choose reliable implants.
What could go wrong
This is an observational study, not a test of a new treatment. It simply collects data on existing devices, so it won't lead to a new cure or therapy. Results depend on real-world factors like patient health and surgeon skill.
