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 Results may not be published yet.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

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This study tests a device called the MISHA Knee System, a small implant placed under the skin near the knee to absorb shock and reduce pain from medial knee osteoarthritis. Researchers will compare it to non-surgical treatments like physical therapy and medication in 100 adults who haven't found relief. The goal is to see if the implant improves pain and knee function after 6 months.

What this could mean

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

Active substance
MISHA Knee System (a knee implant that absorbs shock to reduce pressure on the inner knee)
What this could lead to
If it works, this could offer a new option for people with knee osteoarthritis who haven't found relief from non-surgical treatments, potentially reducing pain and improving function.
What could go wrong
This is an early head-to-head study with only 100 participants, so results may not apply to everyone. The implant requires surgery, which carries risks like infection or device issues.
