Meniscus arthroscopy is usually performed using intralesional anesthesia, or hemianesthesia. General anesthesia may also be chosen depending on the specific condition and the recommendation of the anesthesiologist. Since meniscus arthroscopy is performed on the lower limbs and is not an open surgery, general anesthesia can meet the needs of the surgery. However, general anesthesia can also be chosen in special circumstances, such as the patient’s inability to cooperate or the effect of anesthesia is not good. General anesthesia surgery process, the patient is completely unconscious, the doctor is operating in the patient’s unconscious state, conducive to muscle relaxation during surgery. However, general anesthesia on the respiratory and circulatory system has a certain inhibitory effect, and general anesthesia surgery needs to be awake after the end of the process, the patient is also prone to drug-induced nausea, vomiting and dizziness. Semi-anesthesia when the patient loses the lower body pain, but the sense of touch has not completely disappeared, and in the operation the patient is conscious, the patient needs to cooperate with the doctor to carry out the operation, there may be nervousness, anxiety, fear and other psychological.

Before the operation, the patient needs to cooperate with the doctor to carry out relevant examinations, so that the doctor fully understand the patient’s physical condition, the choice of appropriate anesthesia.
