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 Results may not be published yet.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.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This trial compares two types of surgical tools used during total hip replacement: single-use (disposable) reaming instruments and conventional reusable ones. The main focus is on the overall cost of surgery, including sterilization, materials, and operating room time. Researchers will also track surgical time and patient recovery scores. The study involves 40 adults undergoing their first hip replacement due to arthritis.

What this could mean

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

Active substance
single-use ancillary reaming material
What this could lead to
If single-use tools prove cost-effective and safe, they could become a standard option for hip replacement surgery, potentially reducing infection risks and streamlining hospital logistics.
What could go wrong
The trial is small and early, so results may not apply broadly. Single-use tools might be more expensive or offer no clear benefit over reusable ones.
