Summary

The goal of this study was to perform pulsed radiofrequency ablation with a modified target suggested in the cadaver study by Park et al. (The Knee 27 (2020) 1577-1584) on knee osteoarthritis patients, and to evaluate the effect of reducing the frequency of intravascular injection and reducing pain.

Conditions

• Knee Osteoarthritis

Interventions

Type	Name	Description
PROCEDURE	pulsed radiofrequency ablation to modifined points group	Point 1 place 10mm higher than the boundary between Femur's medial epicondyle and shaft. The 2nd point is targeted 20mm above the patella. Point 3 is targeted 10mm above the femur lateral epicondyle and shaft boundary. At point 4, find the boundary position between the tibia epicondyle and the shaft in the AP view and move it superolateral by 10 mm to target the central part of the medial shaft of the tibia and perform the main touch. Point 5 targets the center of the fibular head.
PROCEDURE	pulsed radiofrequency ablation to conventional points group	Under AP view X-ray fluoroscopy, enter the cannula into the tunnel view until reaching the bone, reaching the border of the shaft and epicondyle, then stop the cannula tip at the anterior 2/3 junction in the lateral view. A total of three target points are the boundary position between the femur medial epicondyle and the shaft, the boundary position between the femur lateral epicondyle and the shaft, and the boundary position between the tibia meidal epiconcyle and the shaft. Subsequent procedure will be proceed same as Arm 1
