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.

详细说明
This study is being done to evaluate the degree of symptom improvement after dual-course low-dose radiation therapy (LDRT) compared to single-course LDRT in participants with osteoarthritis (OA) of the knee.

- Negative pregnancy test
Exclusion Criteria:
- Previous surgery to the affected joint or planned surgery to the affected joint in the next 6 months
- Previous radiation treatment targeting the affected joint. Previous radiation targeting any other body site does not exclude from participation as long as there is no clinically meaningful overlap, as determined at the discretion of the treating physician.

措施说明 |
大体时间 |
|---|---|---|

Change in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score - 6 months
大体时间：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. |

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. |
Baseline to 12 months

|
Change in WOMAC pain sub-domain score
大体时间：Baseline to 12 months
|
Pain sub-domain has 5 items that evaluate pain 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 20 points. Higher scores indicate worse pain. |
Baseline to 12 months
|
|
Change in WOMAC stiffness sub-domain score
大体时间：Baseline to 12 months
|
Stiffness sub-domain has 2 items that evaluate stiffness 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 8 points. Higher scores indicate worse stiffness. |
Baseline to 12 months
|
|
Change in WOMAC joint function sub-domain score
大体时间：Baseline to 12 months
|
Stiffness sub-domain has 17 items that evaluate joint 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 68 points. Higher scores indicate greater physical limitations. |
