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 Results may not be published yet.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.

Summary

This study aims to translate and culturally adapt the Hip Disability and Osteoarthritis Outcome Score-12 (HOOS-12) into Turkish and test its reliability and validity in patients with hip osteoarthritis. Participants will complete the Turkish HOOS-12 and a general health survey at several time points, including before and after hip replacement surgery. The goal is to provide a trusted tool for measuring hip pain, function, and quality of life in Turkish-speaking patients.

What this could mean

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

Active substance
Patient-reported outcome assessment using the Turkish version of the HOOS-12 questionnaire
What this could lead to
If successful, this could provide a reliable Turkish tool for measuring hip osteoarthritis symptoms and treatment outcomes in clinical practice and research.
What could go wrong
This is an observational study focused on questionnaire validation, not a treatment trial. The results may not apply to all Turkish-speaking patients or other settings.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population will consist of Turkish-speaking adults diagnosed with primary hip osteoarthritis who are scheduled to undergo primary total hip arthroplasty at the Department of Orthopedics and Traumatology. Eligible participants will be recruited consecutively during routine preoperative outpatient visits. Participants will complete the Turkish version of the Hip Disability and Osteoarthritis Outcome Score-12 (HOOS-12) and the Short Form-12 Health Survey (SF-12) before surgery. A subgroup of clinically stable participants will complete the HOOS-12 again seven days after the initial assessment to evaluate test-retest reliability. All participants will be reassessed three months after surgery to evaluate the responsiveness of the Turkish HOOS-12.
