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

| Treatment success was defined as the number of subjects whose knee pain is reduced by ± 50% based on the Visual Analogue Scale (VAS). | The VAS is a 11- point scale (0 points to 10 points), where 0 points equals "no pain" and 10 points equals the "worst pain". | one year after the procedure |
| Measure | Description | Time Frame |
|---|---|---|
| Short Form (36) Health Survey | The SF36 values eight parameters: physical function, social function, physical role, emotional role, mental health, vitality, pain and general health. Zero is the worst conceivable health and 100 the best. | one year after the procedure |
| Knee Society Score (KSS) |

The KSS consists of two parts. KS measures pain, range of motion, stability and alignment. FS measures the distance able to walk, the difficulty in going up or down stairs and the need for walking aids. The result is rated as excellent (80-100), good (70-79), regular (60-69) and bad (<60). |
