Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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).

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.

Intervention Type PROCEDURE

Eligibility Criteria
