- The part of the body:
Generally, I only keep patient's awake for arthroscopic knee surgery. Most other arthroscopic procedures required a general anesthesia. There may be some exceptions, you can discuss this with your physician.
- The type of procedure:
Arthroscopic knee procedures that involved more than a meniscus trimming or simple cartilage work, may require more extensive anesthesia. For example, in patients with exposed bone who are undergoing a microfracture, they would usually require more significant anesthesia.
- The ability of the patient to relax:
It is necessary for the patient to be relaxed for the surgical procedure. During arthroscopic knee surgery, it is important for the surgeon to be able to manipulate the knee into certain positions. If the patient is tense, or cannot relax, performing the procedure can be difficult.
- Patient preference:
Some patients do not want to see or hear anything during their surgical procedure. Therefore, these patients may benefit from a deeper anesthesia.
