What this trial studies

This observational study aims to gather data on patient-reported outcomes such as pain, function, and quality of life in individuals with osteoarthritis receiving standard radiation therapy. It is a single-institution, single-arm study that will systematically collect information to optimize radiation therapy management and clinical care. The primary focus is on changes in pain levels measured by a visual analog scale three months after treatment, alongside secondary endpoints assessing disease control and potential surgery avoidance. Participants will complete surveys to report their experiences and outcomes.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 55 and older with osteoarthritis in at least one joint, experiencing inadequately controlled pain despite previous treatments.

Not a fit: Patients who are pregnant, have a life expectancy of less than six months, or have shoulder osteoarthritis will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the management of osteoarthritis through improved understanding of radiation therapy's effects on pain and function.

How similar studies have performed: While there is limited data on the specific use of low-dose radiation for osteoarthritis, similar approaches in pain management have shown promise in other contexts.

Eligibility criteria

Inclusion Criteria:

* Willing and able to provide informed consent
* Established diagnosis of OA of at least 1 joint

* Will undergo radiation as part of their standard of care for OA.
* At least 55 years old
* Ability to read and speak English.

Exclusion Criteria:

* Any woman who is pregnant or has reason to believe she is pregnant (the possibility of pregnancy has to be excluded by negative urine ß-HCG results, obtained within 2 weeks of CT simulation for radiation planning, or on the basis of patient history, e.g.: tubal ligation, hysterectomy or a minimum of 1 year without menses).
