Summary

Chronic osteoarthritis (OA) pain of the knee is not effectively abrogated by the available non-pharmacologic or pharmacologic treatments. Radiofrequency (RF) neurotomy is a therapeutic alternative for chronic pain. Here, the researchers investigate the efficacy of RF neurotomy applied to articular branches (genicular nerves) in treating knee joint pain.

Conditions

  • Osteoarthritis, Knee

Interventions

PROCEDURE

radiofrequency neurotomy for genicular nerve

RF cannula was advanced percutaneously towards areas connecting the shaft to epicondyle of femur or tibia. Lidocaine (1 mL of 2%) was injected before activation of the RF generator (NeuroThermTM, Morgan automation LTD, Liss, UK). RF electrode was inserted through RF cannula. The temperature of the electrode tip was raised to 70℃ for 90 seconds by radiofrequency generator.

PROCEDURE

radiofrequency neurotomy sham therapy

The placebo (sham) group received the same procedure without activation of the RF generator.
