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
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 is testing whether a special ultrasound technique called shear-wave elastography can measure the quality and elasticity of tendons after arthroscopic rotator cuff repair surgery. Researchers will compare the operated shoulder to the healthy one in 75 people who had surgery between 2015 and 2020. They will also use standard ultrasound, physical exams, and patient questionnaires to see if this new method provides useful information about healing and function.

What this could mean

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

Active substance
Shear-wave elastography (SWE) ultrasound examination
What this could lead to
If successful, this could lead to better ways to monitor tendon healing after rotator cuff surgery, helping doctors identify problems earlier and improve recovery strategies.
What could go wrong
This is an exploratory study, so it may not change clinical practice. Ultrasound measurements can vary and may not perfectly reflect true tendon strength or function.
