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 This study

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 early-stage study tests a handheld imaging device that uses magnetic particles to track stem cells after they are injected into the knee. Ten adults with mild-to-moderate knee osteoarthritis will receive a single injection of labeled stem cells, and the device will monitor their location and survival over 30 days. The goal is to see if this new imaging method can better predict treatment success than standard MRI scans.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Diagnosis of knee osteoarthritis according to internationally accepted criteria (e.g., American College of Rheumatology criteria). 2. Age between 18 and 75 years, inclusive. 3. Radiographic Kellgren-Lawrence grade II or III in the target knee. 4. Chronic knee pain of arthritic origin. 5. Absence of local or systemic infection. 6. No contraindications to joint cavity puncture as determined by hematological and biochemical tests. 7. Willing and able to understand the study, provide informed consent, and comply with all study procedures. Exclusion Criteria: 1. Lack of legal capacity or impaired capacity to provide informed consent. 2. Known active infection with HIV, hepatitis B virus, hepatitis C virus, or syphilis (positive serology). 3. Body mass index (BMI) \> 30 kg/m². 4. Congenital or acquired deformity of the target knee. 5. Pregnant or breastfeeding women. 6. History of or current active malignancy. 7. Known immunodeficiency disorder. 8. Intra-articular injection (e.g., corticosteroids, hyaluronic acid) in the target knee within the past 3 months. 9. Concurrent participation in another interventional clinical trial. 10. Any other condition that, in the opinion of the investigator, would make the participant unsuitable for the study (e.g., significant comorbid illness).
