Bloqueo ecoguiado de los nervios geniculados en el manejo analgésico de la artroplastia de rodilla: descripción de la técnica y resultados clínicos preliminares

The administration of 4 ml of local anaesthetic at the level of the 4 genicular nerves of the knee produces a wide periarticular distribution. Our preliminary data in a series of 12 patients undergoing TKA seems to be clinically effective. Nevertheless, extensive case series and comparative studies with local infiltration techniques with anaesthetics are needed to support these encouraging results.
