Summary

This is a prospective randomized controlled trial study will aim to evaluate the the efficacy and procedural pain of BRFA and to compare it with conventional technique (MRFA). And to compare the complications and time taken to complete the procedures.

Conditions

  • Osteoarthritis, Knee

Interventions

PROCEDURE

Monopolar radiofrequency

In monopolar group : . Inferomedial, superomedial, and superolateral GN branches of the patients were identified with ultrasonography, and a 22 Gauge, 10 cm radiofrequency (RF) cannula with a 10 mm active tip was advanced to the targeted nerves under fluoroscopy guidance. The location of the RF cannula was visualized by anteriorposterior and lateral images. Sensory stimulation was applied at 50 Hz to determine the nerve position. Since the sensory stimulation threshold must be \< 0.6 V, nerve position was tested with the absence of fasciculation in the relevant area of the lower extremity upon 2.0 V stimulation at 2 Hz.

PROCEDURE

Bipolar radiofrequency

a similar technique will be used to insert the canula, except that, instead of one cannula two cannulae (approximately 10 mm apart) apart) will be inserted and no manipulation of cannulae was done to stimulate the target nerve as done in MRFA Target areas were similar to monopolar technique Each nerve will be ablated for 90 s in both the groups. All procedures were done by one pain physician who had more then 10 years' experience of radiofrequency procedures.
