Indicações da neurotomia dos nervos geniculares por radiofrequência para o tratamento da osteoartrite do joelho: uma revisão de literatura

Abstract

Osteoarthritis is one of the most frequent and incapacitating pathologies today, especially of the knee. Among the possible approaches for knee osteoarthritis, the neurotomy of the genicular nerves by radiofrequency has been gaining prominence. However, as this is a relatively new procedure, indications for its implementation are still unclear. The objective of this review is to identify the main indications of the use of radiofrequency for the treatment of knee osteoarthritis in the medical literature. A review of the literature was performed in January 2018, through a search in PubMed, Clinicalkey and Google Scholar databases. After reviewing the main articles in the subject, it was concluded that the main indications of the use of radiofrequency for the treatment of knee osteoarthritis were: osteoarthritis grade 3 and 4 Kellgren- Lawrence, with moderate to severe pain and failure of conservative treatment, mainly elderly people; Persistence of pain even after total knee arthroplasty; Patients with an indication for total knee arthroplasty who refuse to undergo surgical treatment.
