Summary

Analyze the results of cooled radiofrequency in patients with chronic knee pain after one year of follow- up.

Detailed description

The investigators performed a retrospective case-series reviewed of 40 patients who underwent cooled RF of genicular nerves. The investigators evaluated results of the survey of quality of life (SF36), knee society score (KSS) and the Visual Analogue Scale (VAS).

Conditions

• Osteoarthritis, Knee

Interventions

Type	Name	Description
PROCEDURE	cooled radiofrequency ablation of genicular nerves	Cooled RF consists of creating an injury in the nerve trough a high frequency flow. Unlike conventional RF, in cooled RF through a closed circuit where intravenous flows, we can create an injury for a longer period of time, at a lower temperature (standard RFA 90º C, cooled RFA 60º C) and within an area 8 times larger. As the lesion is spherical, and larger (about 10-12 mm in diameter), the chances of neurolysis of the nerve increase.
