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 Results may not be published yet.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

Summary

This study investigates whether taking X-rays while standing on one leg gives a more accurate picture of bow-leg deformity (genu varum) than the standard two-legged stance. Researchers will compare alignment measurements from both positions before and after corrective surgery in 70 adults aged 18-65. The goal is to see which stance better predicts how well patients recover function after surgery, potentially improving surgical planning and 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 single-leg stance X-rays prove more accurate, surgeons could better plan corrections for bow-leg deformity, potentially improving long-term knee function and reducing arthritis risk.
What could go wrong
This is a small, early-stage observational study. Differences between stance types may not translate into better surgical outcomes, and results may not apply to all patients.
