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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether a supervised resistance exercise program, done for 2 weeks before and 12 weeks after total hip replacement, improves muscle mass and strength in adults aged 60 and older with severe hip osteoarthritis. Participants are randomly assigned to either the exercise program or standard rehabilitation. The study also looks at biological markers in blood and tissue samples to understand how the body responds to exercise.

What this could mean

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

Active substance
resistance exercise training
What this could lead to
If it works, this could show that a short course of strength training before and after hip replacement helps older adults recover muscle and function better than standard care.
What could go wrong
This is a small, early-stage trial with 70 participants, so results may not apply to everyone. The exercise program is demanding and may be hard for some to complete.

Study facts

What this study's own registry entry says, in plain language.

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 70 people

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

Expected to start

Aug 2026

An estimate. Start dates often move.

Expected to finish

Mar 2029

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

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

Inclusion Criteria: * Individuals aged from 60 y and over. * 18.5 \< BMI \< 40 kg/m2. * Individuals on waiting list to undergo a unilateral elective surgery for Total Hip Replacement due to primary severe Osteoarthritis. Exclusion Criteria: * Individuals with severe OA in the contralateral hip. * Individuals who has been performing regular RET (2 or more times per week) in the previous 6 months. * Individuals who smoke. * Significant psychiatric or neurological disorders, with the use of acetylcholinesterase inhibitors, and untreated mood disorders or depressive pathology. * Neuromuscular or mobility disorders that prevent safe resistance training (debilitating arthritis, spasticity/rigidity, and paralysis), along with untreated metabolic disorders (such as uncontrolled systemic hypertension).
