No results posted yet for this study

Summary

the aim of our study is to compare effectiveness (satisfaction) and duration of pain relief between patients receiving the conventional thermal radiofrequency on the genicular nerves alone vs patients who will receive the conventional method plus alcohol neurolysis of the targeted nerves.

Interventions

PROCEDURE

genicular nerve ablation by thermal radiofrequency

radio-frequency will be done using the Neurotherm NT1100 re-generator. The 3 entry sites will be detected under fluoroscopy then local anesthesia will be performed using lidocaine 2% followed by the insertion of the 3 radiofrequency cannulas (STRYKER 20 G, 9 cm with 1 cm active tip) targeting the 3 main nerves ( superior medial genicular, superior lateral genicular and the inferior medial genicular nerves ) . A confirmation of the targeted sites is done under fluoroscopy in both A-P and lateral views then a motor stimulation will be done to ensure no undesirable motor response followed by lidocaine 1 % injection and placing of the radiofrequency cables and ablation was done at 80 degrees for 90 seconds . The procedure will be repeated 3 times at different levels in the lateral view separated by 0,5 cm to ensure successful targeting. Then remove the needles.

PROCEDURE

genicular nerve ablation by thermal radiofrequency plus alcohol neurolysis

radio-frequency will be done using the Neurotherm NT1100 re-generator. The 3 entry sites will be detected under fluoroscopy then local anesthesia will be performed using lidocaine 2% followed by the insertion of the 3 radiofrequency cannulas (STRYKER 20 G, 9 cm with 1 cm active tip) targeting the 3 main nerves of the knee. A confirmation of the targeted sites is done under fluoroscopy in both A-P and lateral views then a motor stimulation will be done to ensure no undesirable motor response followed by lidocaine 1 % injection and placing of the radio-frequency cables and ablation was done at 80 degrees for 90 seconds . The procedure will be repeated 3 times at different levels in the lateral view. After the radiofrequency is done at each level a 1 ml of 70% alcohol will be injected making a total of 3 ml injection to each nerve Then remove the needles.
