Abstract
We report our experience with knee arthroscopy in local anesthesia in 64 patients with subsequent arthrotomy in 14 of these. The effectiveness of the anesthetic method was evaluated by both the patient and the anesthetic personnel. There was no difference in pain assessment between arthroscopy alone and arthroscopy followed by arthrotomy. Half of the patients had no pain and only one regarded the procedure as very painful. Supplementary analgesia with 0.05 mg fentanyl was given to half of the patients not undergoing arthrotomy and to two thirds of those who had arthrotomy. It was not necessary to abandon any arthroscopic or surgical procedure because of pain. We conclude that local anesthesia is a safe and practical method for diagnostic arthroscopy, arthroscopic surgery, and minor arthrotomy.
