Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in knee pain as assessed by the WOMAC	Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain index assesses participants' pain on a scale ranging from 0 (none) to 4 (extreme). The pain subscale consists of 5 items and total scores can range from 0-20, with larger scores indicating greater pain.	Baseline, 24 Weeks (Post Embolization Surgery)
Primary	Incidence of treatment related adverse events	Procedure-related and target knee osteoarthritis-related adverse events as assessed by treating physician	Up to 4 weeks (Post Embolization Surgery)
Secondary	Change in knee pain as assessed by VAS	Visual Analog Scale (VAS) has a total score ranging from 0-10 with the higher score indicating greater pain	Baseline, up to 52 weeks (Post Embolization Surgery)
Secondary	Change in knee pain	Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain index assesses participants' pain on a scale ranging from 0 (none) to 4 (extreme). The pain subscale consists of 5 items and total scores can range from 0-20, with larger scores indicating greater pain.	Baseline, up to 52 weeks (Post Embolization Surgery)
Secondary	Incidence of adverse events	Procedure-related and target knee osteoarthritis-related adverse events as assessed by treating physician	Up to 52 weeks (Post Embolization Surgery)
Secondary	WORMS Score for Synovitis	Whole-Organ Magnetic Resonance Imaging Score (WORMS) has a score ranging from zero representing no knee problems and 332 representing knee problems	Baseline, up to 52 weeks (Post Embolization Surgery)
Secondary	Kellgren-Lawrence Grade	As assessed by X-Ray. Radiograph imaging graded on scale 1 (no arthritis) to 4 (severe arthritis)	Baseline, up to 52 weeks (Post Embolization Surgery)
