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 Results may not be published yet.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 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 study compares three types of hip replacement surgery—traditional total hip arthroplasty, a neck-preserving Minihip, and hip resurfacing—to see which one best restores the hip's natural biomechanics. Researchers will use CT scans and X-rays before and after surgery to measure hip alignment and offset. 165 adults with hip arthritis will be followed for one year to assess both mechanical and clinical outcomes.

What this could mean

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

What this could lead to
If successful, this study could help surgeons choose the best hip replacement technique for restoring natural hip function.
What could go wrong
This is an observational study, not a treatment trial. It may not lead to immediate changes in surgical practice or patient outcomes.
