Study Overview

Brief 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).

Inclusion Criteria

  • •Chronic knee pain (older than 3 months, with no response to physiotherapy, medication or hyaluronic acid infiltration) with a pain intensity according to VAS>7/10
  • •The radiological criteria were witness of OA with Kellgren-Lawrence index of 2 to
  • •Painful TKA with no apparent cause and with a radiological image where a proper placement was observed

Exclusion Criteria

  • •Infection or lymphangitis of the member
  • •Acute knee pain
  • •Corticoids or hyaluronic acid infiltration with a high molecular weight prior to the surgery
  • •Pregnancy
  • •Severe neurological or psychiatric disorders
  • •Patients with pacemakers

Outcomes

Primary Outcomes

Treatment success was defined as the number of subjects whose knee pain is reduced by ± 50% based on the Visual Analogue Scale (VAS).

Time Frame: one year after the procedure

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".

Secondary Outcomes

  • Short Form (36) Health Survey(one year after the procedure)
  • Knee Society Score (KSS)(one year after the procedure)
