LDRT Retreatment for Knee Osteoarthritis
UW26092: Low-Dose Radiation Therapy for Osteoarthritis of the Knee: A Phase 2 Randomized Trial of Dual-Course Versus Single-Course Radiation
The goal of this clinical trial is to learn if one course of low-dose radiation therapy (LDRT) helps as much as two courses of LDRT in people with osteoarthritis.
The main questions it aims to answer are whether pain control, joint function, and quality of life are the same with one course of LDRT.
Participants will receive LDRT and can expect to be in the study for up to 3 months.

Beschrijving
Inclusion Criteria:
- Clinical diagnosis of osteoarthritis of the knee
- Age ≥40 years at the time of consent
- Joint pain which has persisted for ≥3 months
- Completed imaging of the involved joint in the past 3 months (including MRI, CT, X-ray, or bone scan)
- Negative pregnancy test
Exclusion Criteria:
- Previous surgery to the affected joint or planned surgery to the affected joint in the next 6 months

Change in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score - 6 months
Tijdsspanne: Baseline to 6 months
|
WOMAC is a 24 item questionnaire that evaluates pain, stiffness, and physical function in patients with hip or knee osteoarthritis. Typically rated using a 0 to 4 scale (0 = none, mild, moderate, severe, 4 = extreme), scores range from 0 to 96 points. Higher scores indicate worse symptoms and greater functional limitation. |
