Is this trial a fit for you?

Likely a good fit

Adults 18 and older with OA lasting more than 3 months in the hips, knees, hands, shoulders, ankles, or elbows who have not responded to standard therapies or are being considered for more aggressive interventions but prefer conservative options.

Probably not a fit

Patients who cannot complete the study instruments or do not experience changes in pain or function may not benefit.

What this trial studies

This is a single-arm prospective study conducted at a single institution across multiple sites to evaluate the effects of low-dose radiotherapy on pain and function in osteoarthritis. Participants will complete patient-reported outcome measures to track changes in pain, function, and well-being after treatment. Instruments used include BPI-SF, LEFS, UEFI, and PROMIS Global to capture patient-centered outcomes. The study focuses on individuals who are refractory to standard therapies or are being considered for more aggressive interventions but prefer less invasive options. Results will inform whether LDRT is a feasible option for symptom relief in OA.

Why it matters

Potential benefit: If successful, patients may experience reduced pain and improved function following low-dose radiotherapy.

How similar studies have gone: Previous research in similar approaches has shown mixed results but provides a basis for exploring LDRT in OA.
