What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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

The ROCKETS trial compares robot-assisted total knee replacement with conventional total knee replacement in adults with knee osteoarthritis. Researchers randomly assign up to 1,600 participants to one of the two surgical approaches and follow them for two years. The main question is how many people in each group score 80 or higher on a scale that measures whether they forget about their replaced knee during everyday activities. The trial also tracks pain, function, quality of life, complications, and costs.

What this could mean

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

Active substance
Robot-assisted total knee replacement surgery compared with conventional total knee replacement surgery
What this could lead to
If robot-assisted surgery helps more people stop noticing their new knee, hospitals could adopt it more widely and patients might regain a more natural feel during daily activities.
What could go wrong
Robotic systems are costly and add operating time, and any advantage over standard surgery may be small or fade over years. Results from this trial may not apply to all surgeons or hospitals.
