Fig. 4. Fluoroscopic images of the cooled radiofrequency ablation for genicular nerves of the left knee. (A) Anteroposterior fluoroscopic view after cannula insertion for the placement of cooled radiofrequency electrodes into the junction between the shaft and epicondyle of the tibia and femur. (B) Location of electrodes for the cooled radiofrequency ablation of genicular nerves in the lateral fluoroscopic image. Optionally, the suprapatellar genicular intervention can be performed by inserting the needle 3 cm above the superior patella border at the midline of the anterior distal femoral diaphysis (asterisk). Dashed arrow indicates the needle pathway for the suprapatellar genicular intervention.
