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 Results may not be published yet.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

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.

Summary

This study investigates whether low-dose radiation therapy (LDRT) can reduce pain and improve function in people with osteoarthritis of the hips, knees, hands, shoulders, ankles, or elbows. Participants who have not responded to standard treatments will receive one or two courses of LDRT and report their pain and well-being over a year. The goal is to see if this old technique, used cautiously, can offer relief and possibly delay the need for joint replacement.

What this could mean

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

Active substance
low-dose radiation therapy
What this could lead to
If it works, this could offer a non-surgical option for osteoarthritis pain relief, potentially delaying or avoiding joint replacement.
What could go wrong
This is a small, single-arm study without a placebo group, so results may not prove effectiveness. Radiation, even at low doses, carries a small long-term cancer risk.
