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 This study
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 Results may not be published yet.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.

This status has not been confirmed recently, so it may be out of date.

Summary

Researchers are comparing two common surgical approaches during total hip replacement: removing the acetabular labrum (a ring of cartilage around the hip socket) or leaving it in place. The trial enrolls 200 adults with hip osteoarthritis who are scheduled for a primary unilateral hip replacement. By tracking pain, physical and mental health scores, satisfaction, and surgical factors like operative time and implant positioning, the study aims to determine whether one method leads to better outcomes.

What this could mean

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

Active substance
Surgical technique for handling the acetabular labrum during total hip replacement: either removing it or leaving it in place
What this could lead to
If one approach proves better, surgeons could adopt it as a standard step in hip replacement, potentially improving pain relief, function, and satisfaction for patients.
What could go wrong
Both techniques are already common, and differences may turn out to be small or not meaningful. The trial may not capture long-term effects, and results might not apply to all patients or surgeons.

Study facts

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 200 people

The number the study aims to enrol. It can still change while the study runs.

Show the full entry requirements

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age ≥ 18 years. * Indication for primary unilateral total hip arthroplasty for osteoarthritis (Tonnis grade ≥2 or surgeon's standard indication). * Able to provide informed consent and complete PROMs in English (or validated local language instruments). Exclusion Criteria: * Prior ipsilateral hip replacement or resurfacing. * Active infection or inflammatory arthritis where labral management is judged by the surgeon to be non-standard. * Severe acetabular bone loss or deformity requiring custom implants or complex reconstruction (Crowe III/IV dysplasia). * Planned simultaneous bilateral hip arthroplasty. * Preoperative heterotopic ossification. * Cognitive impairment preventing consent or completion of PROMs. * Patients for whom the surgeon believes leaving the labrum would be unsafe (e.g., gross interposed soft tissue preventing any reasonable cup placement without removal)
