Abstract [eng] This study investigates radiofrequency (RF) plasma temperatures around the active electrode of a bipolar arthroscopic RF resector and human knee meniscus tissue temperatures during RF resection. The aim of this study was investigating radiofrequency (RF) plasma temperatures around the active electrode of a bipolar arthroscopic RF resector and human knee meniscus tissue temperatures during RF resection. Knee arthroscopy knowing the optimal parameters for RF meniscus resection, such as resection temperature, mechanical stress on tissues, and process duration, is important. This study experimentally determined the temperature characteristics of RF meniscus resection using a bipolar RF arthroscopic resector and compared the results with a mathematical model of RF meniscus resection compiled in the COMSOL environment. Discrepancies between modelling and experimental research were obtained that determine the optimal temperature parameters for RF resection of the knee joint meniscus: temperature of HF plasma, meniscus heating temperature during RF resection using a resector in a conductive fluid, and meniscus heating temperature when using analogues in a conductive fluid. The proposed RF resection technology can be used to perform partial resection of the knee joint meniscus. Studies have shown that mathematical modelling of the knee joint meniscus and conductive fluid heating processes due to a bipolar electrode through which an HF current passes closely aligns with experimental data. The optimal conditions for RF resection obtained from thermographic studies and modelling, such as the temperature of the knee joint meniscus and conductive fluid and resection process duration, can improve meniscus injury treatment result.
