Brief Summary
Among knee degenerative osteoarthritis patients aged 50 or older, it will prove the therapeutic effect and safety of Nexsphere-F embolization for patients who need additional treatment because pain is not controlled even if conventional treatments are taken.

Outcome Measures
Primary Outcomes (2)
Rate of WOMAC Score Reduction
The rate of change of WOMAC Score before and after application of medical devices for clinical trials. The definition of clinical success is a reduction of more than 50% of baseline scores (WOMAC and VAS) in six-month observations after at least one knee vascular embolization without additional combination treatment.
1 day, 14 days, 1 month, 3 months, 6 months
Rate of VAS Score (patient pain intensity) Reduction
The rate of change of VAS Score before and after application of medical devices for clinical trials. The definition of clinical success is a reduction of more than 50% of baseline scores (WOMAC and VAS) in six-month observations after at least one knee vascular embolization without additional combination treatment.
1 day, 14 days, 1 month, 3 months, 6 months
Secondary Outcomes (3)
Rate of change in WORMS (Whole-Organ Magnetic Resonance Imaging Score)
1 month
The rate of reduction of medication
6 months
The rate of discontinuation of combination treatment
6 months
Other Outcomes (1)
Number of participants with abnormal cases during follow-up (AVN, skin necrosis, dermal toxicity, acute lower extremity ischemia)
1 day, 14 days, 1 month, 3 months, 6 months
Study Arms (1)
Transcatheter Arterial Micro-Embolization
EXPERIMENTALIf abnormal blood vessels related to pain are identified by angiography, selective embolization is performed using Nexsphere-F.
Interventions
Participants will undergo TAME with Nexsphere-F.
Eligibility Criteria
You may qualify if:
- Those who fall under Kellgren-Lawrence grade 2 to 3 according to the criteria in accordance with ACR guidelines and X-ray findings used within 12 months

You may not qualify if:
- A locally infected patient
- A person whose life expectancy is less than six months

- Those who have a taboo on MR videos
- Pregnant women
- Other cases where it is deemed inappropriate to participate in this clinical trial at the discretion of the researcher
