Transcatheter Arterial Micro-Embolization (TAME) Using Nexsphere-F in Patients With Knee Degenerative Osteoarthritis
A Single Arm, Single Center, Open Label , Pilot Clinical Study to Evaluate the Efficacy and Safety of Transcatheter Arterial Micro Embolization (TAME) Using Nexsphere F in Patients With Knee Degenerative Osteoarthritis

Detailed Description
This clinical trial is a single arm, single center, open label, and pilot clinical trial to prove the performance and safety of Nexsphere-F in patients over the age of 50 who need additional treatment because pain is not controlled even after conventional treatments are taken.
Since consent cannot be obtained during surgery from a subject who meets the inclusion and exclusion criteria, a written consent is obtained in advance between four weeks before the procedure and the day. As one of the usual orthopedic evaluations, baseline MRI will be performed and WORMS will be evaluated. In addition, the WOMAC score and the VAS score will be measured before the procedure and used as a baseline for evaluation variables. Since it is a pilot study to evaluate the validity, all subjects will undergo a Transcatheter Arterial Micro-Embolization (TAME).

1 day, 14 days, 1 month, 3 months, 6 months
|
Rate of VAS Score (patient pain intensity) Reduction
Time Frame: 1 day, 14 days, 1 month, 3 months, 6 months
|
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.
