Summary

Description
This single center, single-blinded, sham-controlled randomized controlled trial will compare low dose radiation therapy and sham radiation therapy for knee osteoarthritis. Participants with symptomatic knee OA based on clinical and radiographic criteria will be randomized 1:1 to receive 0.5 Gy LDRT over 2 weeks ideally on a Monday-Wednesday-Friday three times each week for two weeks treatment course for a total of 3 Gray or identical sham treatment (an identical procedure without the radiation). Non-responders to the initial Low-Dose Radiotherapy (LDRT)/sham treatment will receive a second tre…
