Outpatient arthroscopy of the knee under local anaesthesia.

Arthroscopy of the knee was carried out under local anaesthesia in 313 outpatients, with arthroscopic surgery in 81. The procedure had to be abandoned because of apprehension in only 0.9%. With increasing experience, the number of arthroscopic meniscectomies increased from 5% to 64% of the lesions found. The method was particularly valuable in the assessment of patello-femoral pain since dynamic evaluation of patellar alignment, and the localisation of sensitive structures by palpation, was possible. The method is a safe, reliable and inexpensive alternative to the use of spinal or general anaesthesia for arthroscopy.
