About this trial

The primary aim of this study is to investigate whether low-dose radiotherapy is an effective treatment to reduce the pain of knee osteoarthritis. A secondary aim is to determine whether patients experience any more measurable side effects than those receiving sham treatments.

Treatments tested in this trial

  • Low dose radiotherapy

    Radiation

    Low-Dose Radiation Therapy (LDRT) delivered at 0.5 Gy per fraction for 6 fractions, administered on a Monday-Wednesday-Friday schedule over 2 weeks, for a total cumulative dose of 3 Gy. Delivered to the more symptomatic (index) knee. Participants who report no improvement in knee pain at their 2-month assessment will receive a second identical round of LDRT (totaling an additional 3 Gy).

  • Sham comparator

    Other intervention

    An identical sham procedure without radiation delivery, administered to the more symptomatic (index) knee on a Monday-Wednesday-Friday schedule over 2 weeks (6 sessions total). Participants who report no improvement in knee pain at their 2-month assessment will receive a second identical round of the sham procedure.
