It is by no means a new procedure; Kenji Takazi reportedly was the first to explore the interior of the knee joint using a cystoscope in 1918. Since then, there have been only scattered reports of the use of arthroscopy; the procedure just has not caught on. However, in certain centers throughout the world, the equipment and technique have become quite sophisticated.
