Summary
High-frequency electrosurgery for arthroscopic knee surgery, particularly meniscal resection, shows comparable results to traditional methods. This technique offers advantages in cutting and manipulation without compromising patient outcomes.
Area of Science:
- Orthopedic Surgery
- Minimally Invasive Procedures
- Electrosurgery
Background:
- High-frequency (HF) electrosurgery is routinely used in arthroscopic operations for meniscal resections, lateral release, plica cutting, and arthrolysis.
- The primary instrument is an insulated hook-knife that cuts meniscal tissue, with effectiveness influenced by current strength, instrument design, and cutting speed.
Purpose of the Study:
- To evaluate the efficacy and outcomes of HF electrosurgery in arthroscopic knee surgery.
- To compare the results of arthroscopic meniscal surgery with and without the use of the electric knife.
Main Methods:
- Retrospective analysis of 940 cases undergoing arthroscopic meniscal surgery.
- Assessment of outcomes following procedures utilizing HF electrosurgery versus conventional methods.
Main Results:
- HF electrosurgery provides advantages such as cutting in all directions without resistance and ease of manipulation in confined joint spaces.
- The necrotic depth of meniscal cartilage was not found to be excessive with this technique.
- Follow-up studies exceeding one year showed no significant difference in outcomes between arthroscopic meniscal surgery performed with or without the electric knife.
Conclusions:
- HF electrosurgery is a viable and effective tool for various arthroscopic knee procedures.
- The use of HF electrosurgery in arthroscopic meniscal surgery does not negatively impact patient outcomes compared to traditional instruments.
